[0001] This application claims priority both from U.S. Provisional Application Ser. No. 61/295,869, filed Jan. 18, 2010, and as a continuation-in-part of U.S. Non-Provisional patent application Ser. No. 12/114,454, filed on May 2, 2008, now U.S. Pat. No. 7,871,016, which claims priority both from U.S. Provisional Patent Application Ser. No. 60/915,524, filed on May 2, 2007, and as a continuation-in-part from U.S. patent application Ser. No. 11/509,332, filed on Aug. 24, 2006 now U.S. Pat. No. 7,641,130, which claims priority from U.S. Provisional Patent Application Ser. No. 60/711,858, filed on Aug. 26, 2005, each of which are incorporated herein by reference in their entirety.

[0002] The present invention relates to improved apparatuses and methods for the generation and application of an ultrasonically generated aerosol for uses including but not limited to the sanitization, detoxification, disinfection, high-level disinfection, or sterilization of one or more areas and the surfaces in those areas, as well as the delivery of other types of liquid agents, for various purposes to one or more areas, and without limitation, the surfaces in those area(s).

[0003] The apparatus described in U.S. Pat. No. 4,366,125, which is incorporated herein by reference in its entirety, including any references cited therein, generates a hydrogen peroxide mist by an ultrasonic wave vibrator. The mist adheres to the surface of materials being sterilized and is then irradiated with ultraviolet-ray lamps. U.S. Pat. Nos. 5,878,355 and 6,102,992, each of which is incorporated herein by reference in its entirety, including any references cited therein, disclose a method and device for decontamination of a contaminated process area whereby a fine aerosol of an encapsulant is generated to encapsulate contaminants within a contaminated environment. The aerosol is generated by one or more ultrasonic transducers located below the surface of a reservoir containing a liquid. The output of the transducers is focused to either a point and/or directed toward an area near the surface of the liquid to cause a surface disturbance, which results in the formation of an aerosol from the liquid. The transducers used in these apparatuses are made from lead-zirconate-titanate-four (PZT-4) or other piezoelectric materials. This material is coated with a conductive coating (electrode material) that enables an electrical signal to energize the transducer and causes it to emit high frequency pressure (energy).

[0004] While operating these prior art apparatuses and similar apparatuses, it has been found that certain liquids, especially acidic solutions, chemically react with the electrode materials of the transducers that generate the aerosol. The result is a noticeable deterioration of both the transducers and their performance. For example, acidic solutions of hydrogen peroxide and peroxyacetic acid have caused noticeable deterioration of the transducers within minutes of operation.

[0005] An attempt was made to prevent transducer degradation by coating the face of the transducers with a thin coating of different materials. None of these efforts have been successful. For example, U.S. Pat. No. 4,109,863, which is incorporated herein by reference in its entirety, including any references cited therein, discloses similar findings. The protective coating on the transducer deteriorated to a point where the transducer failed to be energized. It was initially believed that this deterioration was caused by transducer induced cavitation within the tank; however, the aforementioned coatings were also shown to fail in simple immersion tests, conducted over time in an acidic solution, with unpowered transducers. For example, laboratory work indicated that PZT material coated with an electroless nickel plating, or a glaze, were both found to be incompatible with a 4% solution of hydrogen peroxide and peroxyacetic acid, after being exposed to the solution for two weeks at 160° F.

[0006] In addition, it was found that various materials used to construct the transducer housing and assembly experienced deterioration after being subjected to a simulated long-term exposure to an acid solution of hydrogen peroxide and peroxyacetic acid. This was observed with an accelerated aging test. This test consisted of placing components constructed of various material types in vessels containing the hydrogen peroxide and peroxyacetic acid solution and subjecting them to increased temperature over a course of time. Without being limited to the theory, this test is based on the theory recognized in the art that at higher temperatures chemical or physical reactions will proceed faster due to the increased probability that two molecules will collide and chemically react.

[0007] Without being limited to a particular mechanism, method, or chemical, it is believed that chemically reactive liquids are necessary in sterilization processes to contact contaminants including but not limited to toxins, bacteria, virus, fungus, and spores (both fungal and bacterial), prions or protein structures, within a target area(s) either killing the bacteria, fungus, or spores, neutralizing or destroying toxins, or rendering a protein structure incapable of replication or otherwise interfering with the target's cellular physiology. These chemically reactive liquids may be provided as an aerosol. For example, U.S. Pat. No. 4,512,951, which is incorporated herein by reference in its entirety, including any references cited therein, teaches using hydrogen peroxide to sterilize medical devices by condensing hydrogen peroxide-water vapors to deposit a film of liquid on the devices. The liquid film is then evaporated.

[0008] While the prior art attempted to coat the transducer with a protective substance, there were problems with these coatings. U.S. Pat. Nos. 3,729,138; 4,109,863; and 4,976,259, each of which is incorporated herein by reference in its entirety, including any references cited therein, teach that the optimum thickness of a glass barrier, which may be used as a protective plate and/or cover, on a transducer should be any multiple of one-half (½) the wavelength of the transmitted pressure (energy). The thicknesses of protective barriers have been calculated using wave transmission theories and their respective mathematical formulas known to those skilled in the art. It is estimated that twenty percent (20%) of the energy emitted from the transducers is being transmitted into the liquid beyond the protective barrier. The prior art does not include techniques for further increasing the energy emitted from the transducer with a protective plate and/or cover.

[0009] U.S. Pat. Nos. 3,433,461; 3,729,138; 4,109,863; and 4,976,259, each of which is incorporated herein by reference in its entirety, including any references cited therein, teach that an effective thickness of a protective barrier material “interfaced with” a transducer can be approximately any multiple of one-half (½) the wavelength of the transmitted pressure (energy) from the transducer. Prior art has taught that barriers having a thickness equal to or about one-half (½) wavelength constructed from non-conductive and/or insulating type materials like glass, could be effectively coupled with an ultrasonic transducer for generating aerosol, as long as they included a special design consideration for cooling the transducer, or the transducer was separated from the glass barrier with a layer of liquid. U.S. Pat. No. 3,433,461 teaches utilizing a 1.5 inch diameter transducer bonded to a metal barrier that is a one-half wavelength thick. A problem associated with using metal barriers is corrosion, which was acknowledged in U.S. Pat. No. 3,729,138. In addition, U.S. Pat. No. 3,433,461 discloses that heat has a detrimental effect associated with the operation of a transducer and that a metal barrier interfaced with a transducer permitted the use of much higher driving powers than in prior art devices, since it provided more heat dissipation. Further, the driving power supplied to the transducers is limited by the heat dissipation in the device, which is a function, in each case, of the total area of the generator.

[0010] According to U.S. Pat. No. 4,976,259, an attempt was made to bond a glass barrier to a piezoelectric crystal with an adhesive, but such an attempt did not improve on the prior art and resulted in a major loss of acoustic coupling of the ultrasonic energy into the glass cover as the adhesive bond deteriorated. The deterioration was due to high localized temperatures caused by reflected energy resulting from mismatched acoustical impedances.

[0011] The prior art does not currently include commercially effective techniques for constructing and operating a high frequency and high power aerosol producing transducer assembly consisting of one or more transducers bonded or adhered to a protective barrier constructed from non-metallic and/or insulative type materials, such as glass, with a thickness that is not one-half (½) of a wavelength. Furthermore, the prior art does not currently include high frequency and high power aerosol producing glass barrier and transducer assemblies that are capable of operating without additional liquid layers or liquid cooling means incorporated into the transducer assembly design.

[0012] Therefore, the need for a protective barrier for the aerosol producing transducer that is highly resistant to degradation caused by chemically reactive solutions exists. The protective barrier should withstand the heat generated by a transducer and should function effectively with the transducer to produce a fine aerosol at high output levels (which requires high energy emitted by the transducer). This heat is due to the high frequency and energy that is needed to achieve a high output of aerosolized liquid per hour with the aerosol droplets being less than about 10 microns in size. In general, within the effective frequency band, the higher the power at the effective aerosol producing frequencies, the larger the quantity of aerosol produced; and the higher the effective frequency the smaller the droplet size in the aerosol.

[0013] The complete and assured sanitization, disinfection, high-level disinfection, or sterilization of devices, tools, machinery, or other objects or surfaces, within enclosed or unenclosed targeted areas or surfaces, related to industries including, but not limited to, health care, food production, medical device or products, clean rooms, and pharmaceutical, has always been a challenge in terms of overall effectiveness, processing time, cost, and engineering tradeoffs. In addition, the applied agents must have limited toxicity, be reasonably safe, as well as non-harmful to the materials or substances to which they are applied.

[0014] The prior art has extensively taught that relatively quick disinfection and sterilization of surfaces can be achieved by exposing them to an aerosol of a disinfectant/sterilizing agent created by ultrasonic nebulization. The apparatus described in U.S. Pat. No. 4,366,125 (Kodera et al., 1980), which is incorporated herein by reference in its entirety, including any references cited therein, generates a hydrogen peroxide mist by an ultrasonic waves vibrator. The aqueous hydrogen peroxide is heated as it travels from a tank into a basin (col. 4, line 6-8) where it is turned into a fog or mist as the surface of the germicidal liquid in the basin is acted upon by ultrasonic waves. The fog or mist will adhere to the surface of materials being sterilized or disinfected. The surface is then irradiated with ultraviolet-ray lamps.

[0015] G.B. Patent No. 1,128,245, (Rosdahl et al., 1968) which is incorporated herein by reference in its entirety, including any references cited therein, describes a device for disinfecting apparatuses and instruments, including medical instruments. This apparatus also generates a mist of disinfectant, including hydrogen peroxide, by means of an ultrasonic aerosol generator. According to Rosdahl et al., this patent was “primarily adapted for the disinfection of small medical instruments such as scalpels, tongs, syringes, or the like, positioned on a grid in a container” (pg. 3 col. 23-30). However, another separate intended use for a second described apparatus was to disinfect the interior surfaces of objects such as hollow tubing used for “breathing apparatuses” and “heart lung machines” (pg. 1 line 30-36 and pg 2 line 95-101). Rosdahl et al. also taught the use of the germicidal fogging technology to disinfect rooms, apartments and the like (pg. 2 col. 28-30). The pressurized air in Rosdahl et al. is supplied by way of a fan etc. or carrier gas, (pg. 2 line 48-49) and is used to move the generated aerosol as well as to dry objects placed within the enclosed area of the described apparatus. Rosdahl et al. also incorporated “a heating element in the flow path of the carrier gas, to increase drying efficiency” (pg. 3 line 123-127).

[0016] Ultrasonic nebulizers have a unique advantage in that they can create aerosol droplets less than 10 microns in size depending on the power and frequency used in their operation. The small size of the droplets enables them to penetrate small cracks and crevices and to behave like a gas due to Brownian movement and diffusion. In addition, the dense cloud of small droplets is able to form a very thin coating or film over surfaces. The thin coating or film of disinfectant or sterilization agent is able to dry much faster than coatings created by aerosols consisting of larger diameter droplets. It is also theorized that even partial contact of the aerosol droplets with the targeted contaminate(s), can contribute to the overall efficacy of the process. U.S. Pat. No. 4,366,125, (Kodera et al., 1980) taught that heated H2O2 was more efficacious than H2O2 used at room temperature (col. 1, line 19-25). In other words, (Kodera et al., 1980) taught that the efficacious nature of a liquid agent can be increased as it is heated to temperatures higher than ambient temperature. This is desired, without limitation, in the present invention. The text entitled, “Aerosol Technology” by William C. Hinds (1982), which is incorporated herein by reference in its entirety, including any references cited therein, also taught that the size of the aerosol particles produced by ultrasonic means is not only affected by the frequency of the transducer operation, but also by the surface tension and density of the liquid as shown by the following mathematical expression (page 382):
CMD=((y)/(pL)(f^2))^1/3  Equation 1

• • [0017] where: CMD=particle size produced; y=surface tension; pL=liquid density; and f=frequency
    It is commonly known that heating a liquid to point less than its boiling point will reduce its surface tension. Therefore, according to Equation 1 above, a direct relationship was established by William C. Hinds (1982) where one skilled in the art can ascertain that the higher the temperature of the liquid, the lower the liquid's surface tension, which will result in smaller sized aerosol particles. This principal is incorporated without limitation, in the present invention. William C. Hinds (1982) also taught in the same text that smaller diameter particles demonstrate characteristics such as but not limited to, a lower settling velocity, a higher diffusion coefficient, and a higher Brownian displacement (movement), which is desired, without limitation, in the present invention. William C. Hinds (1982) further taught that ultrasonic aerosol generating transducers can heat the surrounding liquid (page 382). This is also desired in the present invention.

[0018] Despite the plethora of advancements shown in the current art, limitations exist in many areas that reduce the effectiveness or viability of the ultrasonic aerosol generator technology in actual commercial applications. The methods and apparatuses of the present invention address the need for an ultrasonic aerosol generator that is, without limitation: (a) designed so that the apparatus can be quickly and easily set up and operated in a reproducible manner on uneven or angled surfaces(s), (b) designed so that the transducers can quickly heat the liquid and liquid surface above and/or around them, (c) designed to prevent or limit dust and debris contamination inside the pressurized air channels or pipes of the apparatus or in the tank in which one or more transducer(s) are located, (d) designed so that if a valve of a liquid storage, holding tank, or reservoir, breaks the tank(s) or reservoir(s) in which the transducer(s) is located is not flooded, (e) designed so that excess, leaked, or spilled liquid can be transferred to a separate containment tank or basin from sources such as but not limited to the fill pipe(s), blower housing(s), internal catch pan(s), transducer tank(s) or basin(s), (f) designed so that the liquid in the tank in which the transducers are located does not drop below the minimum or exceed the maximum operating temperature for that liquid or particular process, coupled with one or more sensor(s) that can determine when an effective or sufficient amount of aerosol has been applied or administered to the targeted area and/or surfaces, (g) designed so that a partially empty apparatus can be easily and effectively refilled, (h) designed to prevent expired liquid that has been added or is otherwise available to the apparatus from being administered by or deployed from the apparatus, (i) designed so that the stream of aerosol deployed from the apparatus can be simultaneously delivered to one or more separate areas.

[0019] It is obvious to those skilled in the art that an apparatus can automatically shut down if an insufficient amount of inventory or product is available with which to complete its defined operational cycle. This activity is also mentioned in French Patent No. FR2860721 (Schwal et al.), which is incorporated herein by reference in its entirety, including any references cited therein. This patent claims the use, by any aerosol generator, of single-use liquid refill/fill cartridges that are associated with specific identifiers, and a reader integrated into the aerosol generator apparatus that can read the said identifiers, all of which is dependently combined with a system of defined steps to establish a set process whereby the apparatus will not generate aerosol if there are any non-conformances related to the entire process, and each cycle of use is terminated with a recording of various information pertaining to the process as a whole. However, according to patent No. FR2860721, the apparatus only notifies the operator if an insufficient liquid quantity is available (pg. 6 line 15-25 and pg. 10 line 10-25) and when it is necessary to replace a filler cartridge (pg. 10 line 15-25).

[0020] Patent No. FR2860721, does not teach or describe an aerosol generator apparatus that can communicate, by any means, to the apparatus operator the quantity of liquid or at least the exact minimum quantity of liquid, expressed in units of measurement, that is necessary to add or make available to the apparatus so that it may successfully complete its desired or chosen operational time or run cycle. The methods and apparatuses of the present invention address the need to provide this information.

[0021] French Patent No. FR2860721 also fails to address the issue of preventing the apparatus from using expired or outdated liquid that is available to the apparatus from, without limitation, one or more tanks or reservoirs inside or attached to the apparatus that have been fed, supplied, or filled by a refill/fill cartridge or other means. This is critical since some liquid agents have a defined period of time of efficacious use once they have undergone, without limitation, dilution from a concentrate or exposure to air. The methods and apparatuses of the present invention address the need to prevent the use or deployment of a liquid agent that is available to the apparatus, but has expired, is unusable, or undesired.

[0022] The need for an ultrasonic aerosol generator that can be positioned and operated from within the area in which the aerosol is being dispersed so as to, without limitation, eliminate or reduce the effects of increased air pressure within the targeted area and operate without damage to its internal and external structures and components is also addressed in the present invention and includes, without limitation, methods and apparatuses such as: (a) means for cooling the various motors, electronics, and other components; (b) properly housing various motors, electronics, and other components to prevent their exposure to the environment surrounding the apparatus; (c) the remote control of and remote communication with the apparatus; (d) preventing any parts of the apparatus that are exposed to the aerosol from becoming higher in temperature than the temperature of the atmosphere surrounding the apparatus.

[0023] There is also a continued need in the market place to increase efficacy and effectiveness from the aerosol and the process of its administration, as well as a system that offers shortened cycle times. The present invention addresses these issues. One such means in the present invention is the utilization of thermal forces and their resultant effects, by cooling or decreasing the temperature of the objects, the atmosphere in which they reside, or the targeted area for the administration of an aerosol as well any surfaces in that area, before the administration of the aerosol to the targeted area or surfaces. Prior art has taught the step of cooling an enclosed area and its surfaces before the administration of a hydrogen peroxide disinfectant, however the hydrogen peroxide was first vaporized into a gaseous state before its administration, and the cooling step was intended to condense the vaporized hydrogen peroxide gas out of the atmosphere in which it was administered and onto the intended surfaces, as taught in U.S. Pat. No. 4,512,951 (Koubek et al., 1983), which is incorporated herein by reference in its entirety, including any references cited therein. More specifically, Koubek et al., teaches a method of sterilization where a liquid of aqueous hydrogen peroxide is vaporized, and the uniformly vaporized mixed hydrogen peroxide-water vapors are delivered into an evacuated sterilizer chamber. The articles to be sterilized are cooled if necessary prior to the introduction of the vapor (or are cooled by the evacuation of air from the sterilizing zone) to a temperature below the dew point of the entering vapors and the condensing vapor deposits a film of liquid on all such cool surfaces (col 2, line 40-51). Koubek et al., also mentions in claim 2 that the result of vaporization was a mixed “gaseous vapor” consisting of hydrogen peroxide and water vapor free of solid contaminants.

[0024] U.S. Pat. No. 4,952,370 (Cummings et al., 1988), which is incorporated herein by reference in its entirety, including any references cited therein, teaches a similar method of sterilization where a liquid of aqueous hydrogen peroxide is also vaporized into a gaseous state before its administration into an evacuated sterilizer chamber. However, Cummings et al., teaches improvements to the art where the hydrogen peroxide-water vapor is applied under vacuum to surfaces that are below 10 degree centigrade, or surfaces in an environment that are both below 10 degree centigrade and above 10 degree centigrade. The cold surfaces mentioned in Cummings et al., were not cooled to accentuate or enhance the process, but were surfaces of components that were inherently cold for their own operational purposes. This is mentioned in sections such as (col 2, line 4-9), (col 2, line 29-33), and (col 4, line 67 to col 5, line 2).

[0025] U.S. Patent Application No. 2005/0042130 A1 (Lin et al., 2003), which is incorporated herein by reference in its entirety, including any references cited therein, claims the use of an applied vacuum to move an ultrasonically derived aerosol, consisting of a sterilant, throughout the area of an enclosed chamber. The use of various vacuum pressures below atmospheric pressure was also mentioned as well as the possibility that vacuum pressures lower than 5 torr lower than atmospheric pressure would likely “enhance the results”, and that using a vacuum pressure low enough to vaporize the sterilant generally enhances sterilization (pg. 2, paragraph 28). However, Lin et al, was silent with respect to how the lower vacuum pressures would “enhance the results” other than any enhancement that vaporization of the aerosol might bring. Lin et al, was also silent with respect to the amount of time that is needed to elapse between lowering the pressure within the enclosed chamber and the application of an aerosol, in order to obtain the needed or desired level of efficacy. (Lin et al., 2003) was silent with respect to cooling any surfaces within the sterilization chamber or applying the aerosol to any cooled surfaces.

[0026] It is important to note that Lin et al, did not mention any process or method to heat the liquid of the aerosol or cool the surfaces in the sterilization chamber before or during the delivery of the aerosol, or any means to incur condensation if the liquid was vaporized. In fact, the 5 torr negative pressure that was used by Lin et al. to generate their findings was reported to be sufficient enough to disperse the mist within the sterilization chamber (pg. 2, paragraph 28), but was never mentioned to have cooled the surfaces within the sterilization chamber or to have that intended effect.

[0027] In addition, it is important to note that the cooling of a targeted environment(s) and/or the surfaces contained therein addressed by the present invention is intended, without limitation, for a completely different application and purpose. The present invention utilizes the principals of aerosol behavior to increase the performance of the process of the present invention, and not the condensation of a gas as taught in the prior art. This is further addressed in the present invention.

[0028] By comparison, the current invention utilizes, without limitation, the cooling of the targeted environment(s) and its surfaces to enhance the performance and efficacy of the aerosol administration process and not to condense a gas as taught by the prior art. The methods and apparatuses of the present invention also address the need to apply an aerosol to surfaces that are without limitation, difficult, impossible, time consuming, or not cost effective to enclose.

[0029] In view of the need for improvements in the current art, the present invention includes improved apparatuses and methods for the generation and application of an ultrasonically generated aerosol for uses including, but not limited to, the sanitization, disinfection, high-level disinfection, or sterilization of one or more areas and the surfaces in those areas, as well as the delivery of other types of liquid agents, for various purposes, to one or more areas, and the surfaces found therein.

[0030] It is preferred, without limitation, that the aerosol is generated within the apparatus and administered into a targeted area and/or onto targeted surfaces by pressurized air or the movement of air or gas. The generated aerosol can be of various sizes, mass concentration or density, and number concentration. It is preferred without limitation that the aerosol is a submicron droplet fog or aerosol of an anti-pathogen, toxin, fungal, sterilization, disinfection, or sporicidal agent(s) or mixtures thereof (herein collectively “agent(s)”). However, any liquid agent(s) may be used in the present invention for various purposes. The fog or aerosol can, without limitation, consist substantially of ten micron to submicron size aerosolized droplets. It is preferred, without limitation, that the aerosol has a higher rather than lower mass concentration or density of droplets. It is also preferred, without limitation, that the aerosol has a higher rather than lower number concentration of droplets.

[0031] The apparatus and methods described in the present invention can pertain to any ultrasonic aerosol producing apparatus. They can also pertain to an aerosol producing apparatus as described in the present invention. This apparatus, briefly described, has one or more piezoelectric transducers that are operated in parallel or series. The transducers are submerged in one or more tanks or reservoirs, and cause a surface disturbance, which results in the formation of an aerosol of the liquid in the tanks or reservoir(s). The one or more tanks or reservoirs in which the transducers are located can be connected to one or more additional tanks or reservoirs that hold the liquid agent. The liquid level in the tank(s) or reservoir(s) in which the transducers are located is controlled by one or more valves which are actuated when the liquid level drops to a certain level causing the valves to open and allows additional liquid to flow in. The tanks or reservoirs also have a means to sense if they are under or overfilled, and can cause the apparatus to shut down if this occurs. The tank(s) or reservoir(s) in which the transducers are located, can be positioned in a chamber that can have a flow of pressurized air/gas, or can be constructed in such a way so that pressurized air/gas can flow through or over them. The pressurized air/gas is intended to move the generated aerosol from the apparatus to the targeted areas or surfaces. The pressurized air/gas can be supplied from sources such as, but not limited to, one or more, fan(s), blower(s), or supply of pressurized air or gas. The apparatus in the present invention can be operated either from inside or outside of the targeted area.

[0032] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises constructing the apparatus so that the aerosol producing transducer(s) and/or their liquid facing surfaces, are able to, without limitation, automatically align themselves with, match the angle of, or remain level with, the surface of the liquid above them. This allows the apparatus to be quickly and easily set up and operated, in a reproducible manner, on uneven or angled surfaces. It also eliminates, without limitation, the need to operate the apparatus on level surfaces. This embodiment includes placing, positioning, or mounting the transducers to or with a gimbal or other similar means known in the art, where the transducers are located at an effective range or depth below the surface of the liquid during their operation. However, it is preferred without limitation that the transducer(s) and their associated parts and housing(s) are designed so that they can be suspended, positioned, held, or maintained, in numerous ways at an effective range or depth below the surface of the liquid during their operation. Without being limited, the transducer(s) and their housing(s) can be suspended, positioned, held, or maintained, at an effective range or depth below the surface of the liquid from an object or component that is floating on the surface of the liquid, partially submerged in the liquid, or completely submerged in the liquid.

[0033] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises interfacing the transducer(s) with a protective barrier that is ground and polished on one or more sides. Polishing the side of the barrier that interfaces with the liquid in the reservoir(s) offers advantages including, but not limited to, ease of cleaning, increased resistance to mineral or foreign object debris deposition or buildup, efficient and effective movement of liquid off of the barrier. In addition, polishing the side of the barrier that interfaces with the adhesive and transducer(s), offers advantages including, but not limited to, reduced variability in adhesive thickness due to diminished variability in the protective barrier's surface features, which can without limitation, reduce variability in transmission related issues.

[0034] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises constructing the enclosing glass plate to have approximately a thickness of about ¼ the wavelength in glass or other material forming the barrier of the transmitted pressure wave generated by the transducer at the natural resonant frequency of the transducer. When the barrier thickness has been calculated, the transducer can be operated at an operational frequency up to 60% percent greater than the natural resonant frequency to achieve a much more efficient operation for the transducer in forming the aerosol. Alternatively, the thickness of the barrier can be varied from the optimal thickness in the range of −0.010 inches to +0.024 inches to increase the efficiency of operation of the transducer. Further, it has been found that the glass or other material barrier thickness may be increased to around various odd multiples of ¼ wavelength and still operate effectively to provide a high volume small aerosol particle output.

[0035] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises enclosing or encircling aerosol producing transducers with one or more wall(s) or barrier(s), that can be, without limitation, continuous or discontinuous, sealed, partially sealed, or unsealed, of various heights including, but not limited to, above the surface of the liquid above the transducers. The purpose of the wall(s) or barrier(s) is to contain the liquid above and around the transducers and use the heat from the transducers to heat that liquid above and around the transducers, and without limitation, the liquid surface above the transducers. The wall(s) or barrier(s) can be perforated or have holes or notches in various orientations or locations in order to allow liquid of various temperatures to flow in and out of the enclosed or encircled areas.

[0036] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises filtering the pressurized air before it enters the apparatus, or at least before entering the aerosol generation chamber. Without limitation, it is preferred that one or more filter(s) is located where the air is drawn or pulled into the apparatus by a blower or fan. The filter(s) can be located either on the inside or outside of the apparatus. The addition of one or more filter(s) prevents or limits dust and debris contamination inside the pressurized air channels or pipes of the apparatus or in the tank or area in which the transducer(s) are located. Various types of filters can be used in the present invention and is dependent on the application. The filter(s), are not used in any configuration(s) or application(s) where aerosol is pulled or pushed from the area in which it was administered, back through the aerosol generator and filtered before it is exhausted out from the targeted or treated area.

[0037] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises connecting one or more tanks between the main tank(s) in which the liquid is stored in the apparatus, and the tank(s) in which the transducer(s) are located, and without limitation, each of the aforementioned tanks have one or more inline valve(s) or float valve(s) that controls the flow of liquid. Without limitation, these connecting tank(s) and valve(s) system(s) act as a check or failsafe mechanism to ensure that the tank(s) or basin(s) in which the transducer(s) are located is not over filled or flooded.

[0038] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises connecting, without limitation, the fill pipe(s) or their spill over tray(s) or basin(s), blower or fan housing(s), internal catch pan(s) or basin(s), transducer tank(s) or basin(s), to one or more liquid containment tank(s). Without limitation, the liquid containment tank(s) are designed to collect excess, spilled, leaked, gathered, or coalesced liquid. This collection system can be connected to the pipe(s) and valve(s) used to drain the apparatus, or it can also have its own drain pipe(s) and valve(s).

[0039] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the incorporation of a means to control or prevent the temperature of the liquid in the tank or basin in which the transducer(s) are located from exceeding the maximum desired, established, or required operating temperature for that liquid or particular process. The prior art has taught that the transducers impart heat into the liquid during their operation. The air that is used to transfer the aerosol from the basin or tank in which the transducer(s) are located to the targeted area(s), can function as a heat removal system. However this pressurized air flow can only remove a certain or calculated number of BTUs or watts of heat due to factors including, but not limited to, the surface area of the liquid in the basin or tank, and the volume and velocity of air that moves over that surface area. If more heat is imparted into the liquid than is removed or dissipated over time, the temperature of the liquid will continue to rise. The means to control or prevent the temperature of the liquid in the tank(s) or basin(s) in which the transducers are located from exceeding the aforementioned maximum desired, established, or required operating temperature, includes without limitation, pumping or otherwise moving the liquid that is in the basin(s) or tank(s) in which the transducer(s) are located, or any other liquid that could possibly have contact with that liquid, through one or more heat exchanger, cooling fins, cooling plate, cooling block, chiller, chilling or cooling apparatus, or other means to remove heat from the liquid. Without limitation, the liquid from the basin(s) or tank(s) in which the transducer(s) are located, can be pumped or moved through one or more cooling fins, chill block, or heat exchanger that is located in the path of the pressurized air that is used to move the generated aerosol out from the apparatus.

[0040] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the remote control of and communication with the apparatus in the present invention. This improvement in the present invention offers many advantages such as, but not limited to, reducing or eliminating the chance of the operator having an accidental exposure to the aerosol from an apparatus that is operated from within the same environment in which the aerosol is applied. The remote control of and communication with the apparatus can be accomplished by means such as, but not limited to, any radio frequency, any light frequency, or directly or indirectly connected wires, or any combination of the said means. Various information, data, and commands can be communicated between the apparatus and a separate means to send and receive information, data, or commands.

[0041] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the apparatus having one or more sensors or the communication with one or more sensors to determine when an effective or sufficient amount of aerosol has been applied to the targeted area and/or surfaces. The sensor(s) consists of a means of varying intensity to project one or more beams of light or a light source, and one or more means to sense the beam(s) of light or light source(s) and indicate its absence or presence. Without limitation, the means to sense the light can vary widely in its sensitivity, and can indicate the presence or absence of the beam or light with a signal such as but not limited to any electrical, fiber optic, or radio frequency signal. It is preferred, without limitation, the sensor consists of a laser and a photoelectric sensor.

[0042] The means to sense the beam of light communicates with a programmable logic circuit, computer, control mechanism or device, or other electronics that control or operate the apparatus (herein called “PLC”), and the presence or absence of a signal or communication causes or results in the apparatus to take actions or undergo activities, such as but not limited to, ceasing the production of aerosol, ceasing the operation of the blower or fan, or even shutting down. It is the intent of the present invention to generate and deliver aerosol into an area until a sufficient amount or density of aerosol is present which will, disrupt, diminish, or completely prevent, the light, beams of light, or light source, from reaching the means to sense the light. The amount of this applied aerosol can vary depending on the application.

[0043] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the apparatus alerting or communicating with the operator if he/she programs the apparatus or otherwise undertakes an activity that would cause the apparatus to operate and generate aerosol for a specific period of time or to fill a specific volume of space with aerosol, and there is an insufficient amount of liquid available in or available to the apparatus for the chosen operating time or volume of space to fill with aerosol, and communicating to the operator the quantity of liquid or at least the exact minimum quantity of liquid, expressed in units of measurement, that is necessary to add or make available to the apparatus so that it may successfully complete its desired or chosen operational time or run cycle. The actual number of needed fill/refill cartridges can also be communicated to the operator. This embodiment includes without limitation, the apparatus having the ability to sense or detect the liquid level or amount of liquid available to the apparatus, or calculating the total amount of liquid available in one or more reservoir(s) that are, without limitation, inside, attached, or otherwise connected to the apparatus. In addition, the means to alert and communicate information to the operator can include but is not limited to any alphanumeric image shown on a screen, monitor, or human-machine-interface (herein called “HMI”), any graphic-user-interface (GUI) shown on a screen, monitor, or human-machine-interface (HMI), lights, lights with associated text, voice commands or directions, or any audible signal.

[0044] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the apparatus having the ability to prevent the liquid agent from being dispersed, that is available to the apparatus from, without limitation, one or more tanks or reservoirs inside, attached, or connected, to the apparatus, which has exceeded its time or date of expiration, exceeded the time or date in which it can be efficaciously used, or has reached a point of time or date where it has degraded or aged to a point where its use is unacceptable. This embodiment does not encompass refill/fill cartridges. The apparatus in this embodiment possesses a means known in the art for measuring, comparing, calculating, or otherwise keeping track of the time between when the apparatus is initially charged or filled with the liquid agent, or the last purge of the apparatus of undesired or unusable liquid, and when the time has been reached when that liquid agent cannot be used and must be disposed of. Once the usable time for the liquid agent has expired, the apparatus can prevent the liquid agent from being dispersed with means including, but is not limited to, using a programmable logic circuit (PLC), control mechanism or device, or other electronics that control or operate the apparatus, to take action(s) that result in stopping the apparatus from generating aerosol. In addition, the apparatus can alert or communicate to the operator that the liquid agent has expired. The means to alert and communicate information to the operator can include but is not limited to any alphanumeric image shown on a screen, monitor, or human-machine-interface (HMI), any graphic-user-interface (GUI) shown on a screen, monitor, or human-machine-interface (HMI), lights, lights with associated text, voice commands or directions, any audible signal.

[0045] An apparatus and method of an embodiment of the present invention, briefly summarized, addresses the cooling of components that can heat up inside of the apparatus when it is being operated in areas such as, but not limited to, the area in which the aerosol is being applied. This situation presents engineering challenges because as the apparatus is operated, its components such as, but not limited to, motors or electronics heat up over time. They cannot be cooled by blowing air from outside of the apparatus past or onto them to remove heat if they are in an aerosol filled environment. This air would contain the administered aerosol and be wet. This condition could pose a risk for unwanted chemical reactions with the components depending on the chemical agent that is present in the aerosol. In one part of this embodiment, the electronics that are used to operate or power the transducer(s) are located in a sealed enclosure and cooled with a means that transfers the heat generated from the electronics into a pressurized air stream. It is preferred, without limitation, that this pressurized air stream is the same air stream that is used to move the generated aerosol out of the apparatus. This helps, without limitation, to minimize the total amperage that is utilized or needed for proper or effective function of the apparatus, which is a critical issue with regard to aerosol generators of this complexity. The one or more heat transfer point(s) can be located before or after the fan(s) or blower(s) that create the pressurized air stream. It is also preferred, without limitation, that the heat generated from the electronics is transferred in various ways known in the art to a heat sink that has fins or other cooling enhancements also known in the art, and the heat sink is positioned in the pressurized air stream. In another part of this embodiment, the components other than the electronics that are used to operate or power the transducer(s), including but not limited to motors or electronics, or the atmosphere in their enclosure(s), are also cooled with a means that transfers the heat generated from the components into a pressurized air stream.

[0046] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises constructing the apparatus in a way that prevents any exterior parts of the apparatus that are exposed to the aerosol from becoming higher in temperature than the temperature of the atmosphere surrounding the apparatus. Generally speaking, this is important because aerosol particles experience a force in the direction of decreasing temperature. This embodiment is applicable and especially beneficial for applications where the apparatus is operated from within the same environment in which the aerosol is applied, and it is desired or required that all of the exterior surfaces of the apparatus have interaction or contact with the administered aerosol. Without this improvement to the current art, the exterior surfaces of the apparatus could become warmer in temperature than the surrounding atmosphere and repel the aerosol, which would prevent the exterior surfaces from having interaction or contact with the administered aerosol if it is desired or required. The apparatus can be constructed in ways that include, but are not limited to, enclosing the components or parts that can heat up in a sealed enclosure and then placing that enclosure inside of another closure that is sealed or unsealed, or insulating the outer skin of the apparatus.

[0047] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises cooling or decreasing the temperature of the objects, the atmosphere in which they reside, or the targeted area for the administration of an aerosol as well any surfaces in that area with refrigerated or chilled air, before the administration of the aerosol to the targeted area or surfaces. This cooling activity or process enables the present invention to utilize the principals of aerosol behavior to increase the efficacy or performance of the process of the present invention. Aerosol particles experience a force in the direction of decreasing temperature. By decreasing the surface temperature of the targeted surfaces, the administered aerosol, and especially an aerosol where the liquid was heated, is drawn towards the cooled surfaces in the targeted area or environment where they interact, interface, or coat the said surfaces with the liquid agent.

[0048] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises utilizing a means to administer the mixture of aerosol and gas or air that is ejected or moved out of the apparatus to one or more separate enclosed rooms or areas. This embodiment does not encompass applications where the areas are within the same room, since this is already known in the art. The said means can include but is not limited to connecting one or more tubes to the apparatus, or splitting the flow from these tube(s) so that they can connect, interface, or otherwise empty into the one or more separate enclosed areas. The said means can also have a means to close off the flow of the air/gas and aerosol to one or more of the said tube(s).

[0049] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises designing the apparatus so that the electronics that operate or energize the transducer(s) may be able to adjust the frequency or frequency range of the signal that is sent to the transducer(s) multiple times during the lifespan of the transducer(s) so that the transducer(s) are able to be consistently operated at a frequency or within frequency range in which the they are able to have an effective or functional output and/or operate at their maximum performance or aerosol output.

[0050] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises connecting, interfacing, or attaching, the aerosol generating apparatus in the present invention to one or more sealed, semi-sealed, or semi-open enclosures or areas. The enclosure(s) has at least five distinguishing features: a) the enclosure(s) is designed to fit over or under various things such as, but not limited to, equipment, objects, or architectural features, etc., b) any walls can have various openings through which any objects may be moved or accessed, c) the enclosure can hang from hooks or other means of attachment that connect to the ceiling or other locations of the area in which the enclosure(s) is located, d) the floors of the enclosure(s) can be constructed with or utilize a surface design or accessory(s) so as to reduce any potential for slip hazards inside the enclosure(s), e) the enclosure can be interfaced with one or means for fire suppression inside or outside of the enclosure.

[0051] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises administering an aerosol into an enclosed area where the floor of that enclosed area is removed, and the surface(s) which the walls of the enclosed area interfaces forms the floor of the enclosed area. This interface can be fully sealed, semi sealed, or unsealed. In addition, one or more holes for access to the enclosed area can also be present in the walls of the enclosed area and the holes can be covered in a matter so that they are sealed or semi-sealed closed, or they can be open and unsealed.

[0052] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the incorporation of a means to add or remove one or more sources of weight or mass from various locations on any of the floated parts of the apparatus including, but not limited to, transducer housing(s), the buoyant objects or components, and/or any of the parts that are directly or indirectly connected to the buoyant objects or components, in order to position or maintain the position of each of the transducer(s) and/or their housing(s) at an effective range or depth below the surface of the liquid.

[0053] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, allowing the buoyant objects or components, and/or any of the parts that are directly or indirectly connected to the buoyant objects or components, as well as the transducers and their housing(s), to freely float in any tank(s) or reservoir(s), where the only anchor point(s) for these parts is the location where the transducer electrical cable(s) and any tubing through which they travel connect either directly or indirectly to the walls of the tank(s) or reservoir(s).

[0054] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises locating the inlet for the inbound air opposite from the air outlet of the fog tank or reservoir in which the transducers are located, and directing or moving the inbound air downward into the one or more reservoir(s) in which the transducer(s) are located. This is coupled with locating one or more openings of various sizes and shapes in the roof of the reservoir opposite from the air outlet. This means can reduce the number of larger droplets in the exiting air stream.

[0055] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises using one or more means to distribute the inbound air to more than one location in the fog tank(s) or reservoir(s) for purposes including, but not limited to eliminating or diminishing any, uneven airflow, uneven air distribution, turbulent air, or vortices, within the interior air space of the fog tank or reservoir. This means to move the air can also be perforated in various orientations with one or more orifices of various sizes and shapes.

[0056] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises reducing the feet per second output of the air exiting from the fog tank(s) or reservoir(s) in which the transducers are located, or otherwise the aerosol generating apparatus, any time near the end of the aerosol generation and delivery cycle. This procedure will promote faster accumulation of the aerosol cloud in the immediate vicinity of the aerosol generating apparatus.

[0057] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises equipping the aerosol generating apparatus with one or more sensors to determine when an effective or sufficient amount of aerosol has been applied to the targeted area and/or its targeted surfaces. The sensor(s) may be directly or indirectly attached to the apparatus, or they may be remotely located in any location where the aerosol is applied or administered. The sensor(s) can be positioned in any orientation and communicate with the aerosol generating apparatus in various ways such as, but not limited to, radio, sound, fiber optics, or wires, all in a manner known to those skilled in the art.

[0058] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the operation of a means to dehumidify the area in which the aerosol was administered, any time after the aerosol deployment cycle has finished, or the aerosol generating apparatus was shut down for any reason(s). In one embodiment, a dehumidifier is used as an independent apparatus “not” connected to the aerosol generating apparatus. It may be remotely controlled or programmed by the operator all in a manner all known to those skilled in the art. In another embodiment, an independent dehumidifier is used, but in this particular embodiment it is controlled by, and electrically connected to, the aerosol generating apparatus. The operation of the dehumidifying apparatus is controlled by the software or computer program that operates or controls the aerosol generating apparatus. In an additional embodiment, the means to dehumidify the area in which the aerosol was administered, is enhanced so that it contains one or more filter media to filter the aerosol before, during, or after it passes over the chill coils.

[0059] Filtering the deployed aerosol was initially demonstrated by the inventors of the present invention in a public area at the Richland, Wash. Municipal Airport on Oct. 9, 2003. Staff from Washington State University, observed aerosol created by the aerosol generating apparatus described in the present invention, pass through a long tortuous path created with 150 feet of six inch diameter flex ducting, that terminated with various filter media including a HEPA filter and a furnace filter. This same system was used to dehumidify and dry the system of ductwork, after the aerosol was deployed.

[0060] In an embodiment, the dehumidifier can also incorporate a means to receive any type of signal from various sources including, but not limited to, the aerosol generating apparatus, or any means for remote control, to not only signal the dehumidifier to dehumidify a targeted area or environment, but also to complete or terminate the dehumidification process by moving, switching, or directing the air flow through a separate filter, such as, but not limited to, an activated carbon filter, or any filter that can remove various gases or vapor(s) from the treated area(s).

[0061] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the construction and use of a means to effectively cover and/or seal the various types of vents that can be found in treated areas including, but not limited to, inbound and outbound air vents for a building HVAC system. These air vents are commonly found in facilities such as, hospitals, schools, clinics, factories, laboratories, and clean rooms. Many times these vents have one or more protruding metal geometries, which makes sealing the vents difficult or impossible with current means. In addition, sealing these vents can be time consuming as well as dangerous because ladders are often necessitated to reach the ceiling mounted vents. The improved means to effectively cover or seal the various types of vents, consists of parts such as but not limited to, a vent cover with sealing material to seal it to the vent or any surrounding or connected areas or materials, any pole which can, without limitation, be adjusted or modified for length, and a means to directly or indirectly connect the pole to the vent cover. In another embodiment, the pole with adjustable length can be constructed so that its one or more ends that are opposite from the vent cover has a means to swivel or articulate so that the base(s) of the pole can articulate at any angle with the floor or any other surface that it contacts. In an additional embodiment, any surfaces of the end(s) of the pole that is compressed or pushed down onto any surface that results in the compression of the vent cover or its seal material can be, without limitation, formed from, coated with, adhered with, or consist of any absorbent material. This material can be, without limitation, treated or saturated with any liquid, at any time, consisting of any anti-pathogen, toxin, fungal, sterilization, disinfection, or sporicidal agent(s) or mixtures thereof (herein collectively “agent(s)”). However, any liquid agent(s) may be used in the present invention for various purposes.

[0062] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises modifying a magnetic vent cover so that it has one or more attachment points where a means, such as, but not limited to, rope, cord, thread, wire, cable, twine, tube, or hose, can be attached to the vent cover so that it may be easily removed from a ceiling or ceiling vent eliminating the need to use a ladder. The magnetic vent cover is known to those skilled in the art, and is commonly found in the form of a flexible sheet that is embedded with one or magnets, or coated or laminated with one or more magnetic materials.

[0063] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the utilization of one or more means or holder to prop or hold any items such as, but not limited to, any hose(s), wire(s), cord(s) that are present in the area in which the aerosol is administered or lead to or from the aerosol generator(s), so that they are prevented from touching or contacting any floor or surface on which the holder is placed. The use of the holder(s) helps to reduce or eliminate an incomplete treatment or administration of the aerosol to all of the desired or needed surfaces in a targeted area. The holder(s) can, without limitation, have absorbent material placed between the holder and any surface(s) on which the holder is placed or interfaces. Absorbent material can also, without limitation, be placed between the holder(s) and any object(s) that it holds or supports. The absorbent material may, without limitation, be soaked, saturated, or contacted with any liquid or substance for various purposes before, during, or after the holder is interfaced with an object(s) or placed on a surface(s) or floor.

[0064] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the construction and use of a means to isolate or maintain one or more wheels, tracks, or other means for providing movement (herein collectively “wheel(s)”), that are directly or indirectly connected to the aerosol generating apparatus or any aerosol or vapor generating apparatus, so that they are in direct or indirect contact with one or more materials (herein collectively “absorbent material(s)”) that can hold, contain, or absorb, without limitation, any liquid, (a) mixture or solids suspended in any liquid, (b) solution, (c) medication, (d) organisms suspended in any liquid, (e) anti-pathogen/toxin/fungal/sporicidal agent(s) or substance(s), (herein collectively “agent(s)”), and prohibit the wheel(s) from directly touching any floor or other surface that it would otherwise come in contact with when it is moved, stopped, or held in a static or semi-static position. Furthermore, the absorbent material in this embodiment is treated with any liquid agent, in various ways known to those skilled in the art, and enables, without limitation, wheel surfaces and surfaces under the wheel to be treated or come in contact with the intended or applied agent(s). The implementation of this means improves the art, and can ensure, without limitation, that any surfaces under or associated with any wheels, tracks, or other supporting structures, are sterilized, sanitized, disinfected, high level disinfected, decontaminated, or otherwise treated with any agent(s) for any intended effect.

[0065] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, filtering any liquid utilized, processed, or located in the apparatus, in one of more locations, as well as anywhere along the path of any circulating or moving liquid in the apparatus. Furthermore, the aerosol generating device may be designed so that all pipes, filters, pumps, and valves may all be positioned and plumbed so that when the apparatus is drained, all of these components and plumbing may be fully emptied of any liquid.

[0066] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the design and/or plumbing of any housing, conduit, or cover, for any blower, fan, or other source of pressurized air, so that it can be drained of any accumulated liquid that may reside inside. The liquid can be drained to any location or ports in the apparatus in a manner known to those skilled in the art.

[0067] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the design of a sealed or semi-sealed tank or reservoir in which any aerosol is generated, where one or more pipe(s), tube(s), hose(s), or other enclosed means for transporting the generated aerosol (herein collectively “fog tube(s)”) out of the fog tank, protrudes into the fog tank or reservoir from the exterior of the machine, fog tank, or reservoir, and the orifice or open end of each fog tube is located approximately above and/or to the side, of each transducer, or other type of aerosol emanating device. The effectiveness of the fog tubes(s) diminishes at a distance greater than three (3) inches from the surface of the liquid under which the transducer(s) is located, or the source of the generated aerosol. Performance and effectiveness is also impacted by the length of the fog tube(s). A visually noticeable and desired behavior and consistency of the deployed aerosol is observed when these fog tube(s) are utilized. The deployed aerosol appears visually lighter, and it appears to float longer in the air, supporting the theory that this design enhancement enables the apparatus to deploy aerosol droplets with a smaller average size.

[0068] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the design of the air outlet of the fog tank or reservoir, so that it has a door or cover that can, without limitation, be effectively sealed closed or opened. This door can be mounted, removed, or attached, all in a manner known to those skilled in the art. This improvement can, without limitation, reduce or eliminate any vapor emanating from the apparatus when it is moved or sitting idle.

[0069] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the design of the apparatus and its software so that the programmable logic circuit (PLC) and/or HMI shall keep a record of the time between purges of the liquid agent(s) in the apparatus to ensure that expired agents are not utilized by preventing the operation of the apparatus. The apparatus can, without limitation, be prevented from or cease to function until the apparatus is drained and replenished with fresh liquid after it has expired or reached a point where it loses efficaciousness, or at a minimum prompting the operator though the use of an HMI that the liquid or agent in the apparatus has expired. This can help maintain quality control and quality assurance for the apparatus and its processes in a manner known to those skilled in the art.

[0070] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the positioning of one or more sensors to determine when an effective or sufficient amount of aerosol has been applied to the targeted area and/or surfaces, near the ceiling of the area in which the aerosol or agent is deployed. The sensor(s) can be, without limitation, mounted on any pole, tripod, or connected anywhere to any structure or apparatus. Furthermore, the sensor(s) mounted near the ceiling can work in tandem with similar sensor(s) located near approximately ground level. This is important since aerosol behavior can be impacted by various attributes such as, but not limited to, the temperature of the deployed aerosol, and the temperature of the atmosphere in the area in which the aerosol is deployed. This embodiment further improves the art to account for these different operating scenarios.

[0071] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, the incorporation and use of a device that includes one or more of any housing or area (herein collectively “blade housing(s)”) that holds, without limitation, a plurality of any paddle(s), blade(s), or other moving surface(s) (herein collectively “paddle(s)”), that are otherwise moved, rotated, or spun. This device is intended to cause aerosol particles to impact against, without limitation, any of the paddle(s) and/or any of the interior surfaces of the blade housing(s), resulting in the removal of aerosol from the air. It is preferred, without limitation, that one or more paddles attached to a movable shaft are positioned in front of each inlet and outlet for each blade housing(s). It is even more preferred, without limitation, that these paddles are mounted to a common shaft in different angles or orientations to create a more tortuous path for the air/gas and aerosol as it moves through the blade housing(s).

[0072] This device can improve the effectiveness and efficiency that is needed to remove various amounts of aerosol from any air or gas when it is necessary or desired to do so. This device can, without limitation, function independently, or be installed within any airflow of any apparatus, such as, but not limited to any aerosol generating apparatus, or any dehumidification apparatus.

[0073] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises improvements to the art as taught by U.S. patent application Ser. Nos.: 09/855,546 Morneault et al., 10/671,837 Morneault et al., and U.S. Pat. No. 7,045,096 B2 to D'Ottone, which are incorporated herein by reference in its entirety, including any references cited therein. The prior art and the improvements that they teach, as well as these new improvements can, without limitation, be incorporated into the present invention in order to help reduce or eliminate any odors at the end of a treatment cycle from any aerosol or vapor generating apparatus.

[0074] In the first part of this embodiment, one or more of any ultraviolet (UV) light sources of any wavelength can be, without limitation, contained in one or more of any enclosure connected to any air or gas stream, and the enclosure(s) can be of any size, shape, or made from any materials. Furthermore, at least one, but preferably all of the walls, ceilings, and floor, of the enclosure are, without limitation, lined with mirrors. The mirrors can help to increase the effectiveness and efficiency of the process of treating the air or gas that is moved through the enclosure, as greater amounts of the emitted light is bounced back or redirected from the mirrored surfaces and into the enclosure space.

[0075] In the second part of this embodiment, the processed air or gas can be, without limitation, channeled or moved through one or more tortuous path(s) or complex maze(s) of mirrored channels populated with one or more of any ultraviolet light sources positioned in various areas of the channels. This torturous path or complex maze serves various purposes including, but not limited to, increasing the amount of UV light exposure to the processed air or gas.

[0076] In the third part of this embodiment, the flow air or gas can be, without limitation, disrupted with various means, such as but not limited to baffles to cause a turbulent flow of air or gas at various locations within the enclosure in which the UV light sources are located, including, but not limited to, near the source(s) of UV light, or between the sources of UV light.

[0077] In the fourth part of this embodiment, the UV light lamps or bulbs, can not only be installed so that they are vertical and offset to the direction of the air or gas flow as taught by Morneault et al, in U.S. application Ser. No. 10/671,837, (paragraphs 19-20) but they may also, without limitation, be located in any angled orientations relative to the direction of the air or gas flow, and they can also be offset to one another as well. This can also help to increase the efficiency of the process as, without limitation, the UV light contacts the air or gas, first as the emitted UV light is redirected by the mirrors, and then again as the air or gas flows closer and then past the UV light source(s). The UV light source(s) can also be installed horizontally and offset, to the direction of the air or gas flow. This can, without limitation, be combined with the mirrored surfaces of the UV light source enclosure previously mentioned above.

[0078] In the fifth part of this embodiment, one or more of any UV light source(s) can be, without limitation, positioned anywhere in the air or gas stream of a dehumidifying apparatus. In addition any air or gas, from any area treated by any aerosol or vapor generating apparatus, can be processed or treated with any UV light source and/or any dehumidifier, at any time or during any stage of any treatment cycle, for any period of time, to reduce or eliminate any unwanted or undesired odors. The treated air or gas can, without limitation, contain any concentration of any aerosol or gas that contains any applied agent(s) in any concentration. The dehumidifier and UV light source(s) can, without limitation, be operated at the same time, or at different times.

[0079] In the sixth part of this embodiment, any aerosol generator can, without limitation, incorporate the use of one or more of any UV light source(s), and/or any dehumidification technology, anywhere in its design. The dehumidifier and UV light source(s) can, without limitation, be operated at the same time, or at different times. Any air or gas, from any area treated by any aerosol or vapor generating apparatus, with any liquid agent(s) can also be processed or treated with any UV light source and/or any dehumidifier, at any time and for any duration, or during any stage of any treatment cycle to reduce or eliminate any unwanted or undesired odors in the treated area.

[0080] In the seventh part of this embodiment, the UV light source(s) can, without limitation, be combined with any aerosol or vapor generating apparatus that emits an aerosol or vapor containing one or more of, in any concentration, hydrogen peroxide, peroxyacetic acid (PAA), or any other aqueous solutions or agent(s) that are acidic, or any combinations thereof. This embodiment can also, without limitation, be combined with the use of a dehumidification technology. According to U.S. Pat. No. 7,045,096 B2 to D'Ottone, a high relative humidity (RH) increases the effectiveness of the invention as water droplets can deliver concentrated solutions of hydroxyl free radicals throughout the area in which it is employed ('096 patent, line 56). This effect can be, without limitation, enhanced in the present invention, as the dense cloud of very small aerosol droplets and vapor that is suspended in the air or gas in the treated area(s), is pulled into the enclosure or area that houses the UV light source(s) and is treated by the UV light and then deployed back into the treated area(s). This may, without limitation, be more enhanced when the aerosol or vapor droplets are less than ten (10) micron in size. This may, without limitation, be even more enhanced when the droplets are generated with ultrasonic processes, which are known to emit large amounts of aerosol droplets less than five (5) microns in diameter.

[0081] The use of any dehumidifier that is, without limitation, directly or indirectly connected to one or more UV light source(s) can also add an additional synergistic effect by reducing the relative humidity of the air or gas stream that is presented to the UV light source(s) after one or more passes of the same air or gas from the treated area(s). This may be beneficial as it may, without limitation, be possible to initially inundate the UV light source(s) with limiting conditions such as, but not limited to, too much humidity, or too much aerosol, which could wet the UV light source(s) under certain conditions known to those skilled in the art, and their performance or efficiency of the UV light source(s), such as in eliminating bacteria in the air or gas stream, could be decreased. In addition, according to U.S. Pat. No. 7,045,096 B2 to D'Ottone, to reduce the rate at which the ozone spontaneously decomposes into oxygen it is preferable, if possible, to lower the temperature of the inside of the enclosure ('096 patent, lines 48-51), where the UV light source(s) are located. The UV light source(s) can, without limitation, be located in close proximity to, in the same enclosure as, or effectively near, any chill coil(s), cooling tube(s), or cooling surface(s), associated with any dehumidifier designs known to those skilled in the art, to help reduce the temperature of the air or gas near the UV light source(s) to an effective temperature between 0-70 degree Centigrade, and more preferably near 0-15 degree Centigrade.

[0082] According to U.S. application Ser. No. 10/671,837 by Morneault et al, (paragraph 8), “A variation of photocatalytic oxidation, dubbed Advanced Photocatalytic Oxidation (APO) is defined by the complementary utilization of any ozone, hydrogen peroxide, or reactive material surfaces such as titanium dioxide in tandem with UV energy, and is deemed to yield higher oxidation performance, but it comes with the higher costs to operate and bulkiness to the apparatus.” This effect can also, without limitation, be enhanced in the present invention, as the aqueous aerosol or vapor, containing any amount of hydrogen peroxide or peroxyacetic acid (PAA), is pulled into the enclosure or area that houses the UV light source(s), from the treated area(s), and is treated by the UV light. The aqueous aerosol or vapor in the present invention is unique because it provides the benefit of inherently providing the needed substance(s) to yield higher oxidation performance without any additional cost, bulkiness, or complexity to the apparatus. This synergism may also, without limitation, be accomplished with any other aerosols consisting of any other agent(s) that can have the same or similar effect.

[0083] The combination of one or more of these various technologies such as, but not limited to, any enclosed UV light source(s), dehumidification, and any aqueous aerosol generator or vapor generator, technologies, especially when combined with the use of any aerosol containing any hydrogen peroxide and/or peroxyacetic acid (PAA), can without limitation, create an enhanced synergy that can be used for a quicker process to not only decontaminate, sanitize, disinfect, or sterilize, a targeted area and various surfaces within the targeted area, but to also quickly reduce or eliminate odors or smells in the targeted area that results from these activities. This can, without limitation, be especially important when using agent(s) that contain ingredients such as, but not limited to, peroxyacetic acid (PAA). This synergy, can also, without limitation, be even more enhanced when acidic agent(s) are deployed into a targeted area and treated by the UV light source(s). This can translate to quicker overall cycle or turn over times for a treated space.

[0084] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises using any combination of sensors, programmable logic circuit (PLC), computer software, algorithms, or other automated means known to those skilled in the art, to automatically adjust and modify the timing sequences and time periods of various steps of the operational cycle performed by any aerosol generating apparatus or any ancillary equipment, at any time, to account for various attributes such as, but not limited to, the total volume of the treated space, temperature of the air or gas in the treated space, the relative humidity level in the treated space, the dew point in the treated space, and the atmospheric pressure in the treated space. In addition, the operator of the apparatus can, without limitation, manually enter into the apparatus one or more values such as, but not limited to, the volume of the room or treated space, or the desired operational time for any of the various steps of any operation cycle.

[0085] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the aerosol generator conducting or carrying out, without limitation, the following operational steps or sequences. One or more of the following steps can also, without limitation, be bypassed either temporarily or permanently per the desires or needs of the operator. Each step can vary for any length of time for any reason known to those skilled in the art. In addition the time between each step can also vary for any length of time for any reason. The first step is aerosol generation and deployment into the one or more targeted area(s). This step includes, without limitation, the additional step of heating the liquid that will be aerosolized to any preset temperature. The second step provides a dwell time to allow the aerosol and any vapor component to have efficacious contact with any targeted surfaces and/or area(s). The third step is dehumidification. Dehumidification can be achieved in various ways known to those skilled in the art. Dehumidification can also, without limitation, include operating any spinning paddles or blades as mentioned in the present invention, and this can be operated with our without any other dehumidification device(s) or methodologies. The fourth step is deodorization. This is achieved by using one or more UV light source(s) as described in the present invention. The fifth step is filtering the air with one or more of any filter(s) to remove any amount of any unwanted gases or vapor. Furthermore, the aerosol generating apparatus may stop all other steps and enter into or start the dehumidification step at any time for any reason. The dehumidification step may be started for reasons including, but not limited to, the apparatus or operator has detected a fault with any part or operation of the apparatus or any other ancillary equipment, an emergency stop has been actuated, or the operator has chosen to abort or stop the function of the apparatus. Finally, the operator of the apparatus can, without limitation, manually operate the dehumidification step or deodorization step either any time before the aerosol generating apparatus has started to generate and deploy any aerosol, or any time after the entire operational cycle is complete.

[0086] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises the construction and use of one or more means to effectively cover, plug, and/or seal any space(s) or gap(s) that can be present near or at the bottom of any door or set of doors when they are closed. These space(s) or gap(s) can also occur even when seals are attached to the bottom of a door(s). These spaces(s) or gap(s) can, without limitation, leak any applied aerosol depending on various variables known in the art, when a room or space is treated.

[0087] Various door seals are used in the present art to prevent drafts from emanating from under doors. However, the present invention improves the current art, by designing and constructing an enhanced door seal that it not only effectively seals the door, but it also insures that various surfaces such as, but not limited to, the surfaces of the door and door seal that are in contact with each other, as well as any floor, door frame, or flooring material, have sufficient exposure to any applied agent(s) so they may be sterilized, sanitized, disinfected, high level disinfected, or decontaminated.

[0088] An apparatus and method of an embodiment of the present invention, briefly summarized, comprises without limitation, moving or pumping any quantity of air or gas from any area treated with any agent(s), in the form of an aerosol, through a liquid contained in one or more tank(s) or reservoir(s). The liquid is any substance that can, without limitation, neutralize, degrade, or remove, any odors or vapor from the processed air or gas. The liquid can also, without limitation, neutralize or degrade any liquid agent(s) that the aerosol may contain. The air or gas can be, without limitation, recirculated one or more times before it returned to the treated area or any other designated space.

[0089] Numerous other features, aspects and advantages of the present invention will be made apparent from the following detailed description taken together with the drawing figures.

[0185] Detailed references to the embodiments of the invention, are illustrated in the accompanying drawings that serve as examples. While the invention will be described in conjunction with the embodiments, it is understood that they are not intended to limit the invention to those embodiments. On the contrary, the invention is intended to cover alternatives, modifications, and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims.

[0186] As illustrated in FIGS. 1-5B, an embodiment of the invention includes a method and apparatus for protecting and enhancing the performance of one or more aerosol generating ultrasonic transducer(s) (10) by adhering one or more protective barrier(s) (60) to a transducer(s) (10). Unless otherwise stated, adhering in this specification includes, but is not limited to adhering, coupling, gluing, attaching, cementing, cohering, fastening, pasting, depositing, applying, melting onto or melting together, and chemically, thermally, or physically bonding. According to an embodiment the transducer(s) (10) may be made of a piezoelectric material, preferably a lead-zirconate-titanate (PZT) material, and more preferably lead-zirconate-titanate-four (PZT-4). According to an embodiment, the protective barrier (60) may be any material that has an effective or high chemical resistance to a liquid (30); however any material that has an effective coefficient of conductivity for pressure (energy) could also be used. Further, the protective barrier (60) may be a pane, sheet, or plate, and may be made of materials such as glass, ceramic, or a polymer. According to an embodiment, the thickness of the protective barrier(s) (60) can range from about 0.001 inches to about 0.125 inches, wherein the thickness is not equal to or about n/2 of a wavelength of sound or pressure (energy), preferably in the form of a wave, generated by the transducer(s) (10) at a frequency, wherein n is any integer. In an embodiment, the liquid (30) may be, but is not limited to one or more of any chemical, compound, mixture, or substance, which is a liquid, preferably a solution, and may optionally include but is not limited to water, medicines, fertilizers, pesticides, fuels, chemical neutralizers, or anti-pathogen/toxin/fungal/sporicidal agents, substances, combinations thereof, and the like. According to an embodiment, the liquid (30) may also be heated to achieve a desired aerosol (200) output.

[0187] According to an embodiment, a protective barrier (60) is adhered to the side of the transducer(s) 10 that faces the liquid (30), preferably hydrogen peroxide and peroxyacetic acid in solution, to separate the transducer(s) (10) from the liquid (30). In an embodiment, the protective barrier (60) is quartz glass and is adhered to the transducer(s) (10) by an adhesive (70) whose performance is unaffected and/or not adversely affected by heat. No liquid or other medium, other than the adhesive (70) (and optionally, a conductive coating (50)), is necessary between the transducer(s) (10) and the protective barrier (60) for the transducer(s) (10) to function properly. According to an embodiment, the thickness of the protective barrier (60) ranges from about 0.001 inches to about 0.125 inches, wherein the thickness is not equal to or about n/2 of a wavelength of pressure generated by the transducer(s) (10) at a frequency between about 0.025 MHz and about 10 MHz, wherein n is any integer, preferably a thickness between about 0.026 inches and about 0.070 inches at a frequency between about 0.5 MHz and about 2.5 MHz, more preferably a thickness between about 0.030 inches and about 0.060 inches at a frequency between about 1.2 MHz and about 2.2 MHz, and even more preferably a thickness between about 0.029 inches and about 0.042 inches at a frequency between about 1.2 MHz and about 2.2 MHz.

[0188] Referring to FIGS. 1 and 2, an embodiment of the invention includes one or more aerosol generating ultrasonic transducer(s) (10) (and their housings (20), if utilized) located below the surface of a solution, fluid, or liquid (herein collectively “liquid”) (30) in a reservoir (40). According to an embodiment, the liquid (30) can be, but is not limited to one or more of any chemical, compound, mixture, or substance, which is a liquid, preferably a solution, and may optionally include but is not limited to water, medicines, fertilizers, pesticides, fuels, chemical neutralizers, or anti-pathogen/toxin/fungal/sporicidal agents, substances, combinations thereof, and the like.

[0189] According to a preferred embodiment, a preferred liquid (30) is hydrogen peroxide and peroxyacetic acid in an aqueous solution, which may be effective in sanitization, disinfection, high-level disinfection, and sterilization, and other applications, preferably approximately 2.2% hydrogen peroxide and approximately 0.45% peroxyacetic acid in solution, more preferably approximately 1% hydrogen peroxide and approximately 0.25% peroxyacetic acid in an aqueous solution. Other liquids (30) that may be used include, but are not limited to chlorine dioxide in solution and ozone in solution.

[0190] The tank or reservoir (40) may be made of any suitable material that is not affected by the chemical action of the liquid (30). Suitable materials of the reservoir (40) may include PVC, polypropylene, and stainless steel, but other suitable materials may be used. The aerosol (200) generated by operation of the transducer(s) (10) forms above the surface of the liquid (30) in the reservoir (40) and may be transferred from the reservoir (40) to the space to be treated by a blower (180) or other source of pressurized air, as will be described in greater detail below.

[0191] The output of the protected transducer(s) (10) may be focused or directed to a point and/or an area near the surface of the liquid (30) to cause a surface disturbance, which results in the formation of an aerosol (200) of the liquid (30) in the reservoir (40). The aerosol (200) is then blown or otherwise moved with pressurized air, into one or more targeted areas or chambers.

[0192] According to an embodiment, the transducer(s) (10) may be made of a piezoelectric material, preferably a lead-zirconate-titanate (PZT) material, and more preferably lead-zirconate-titanate-four (PZT-4). With reference to FIG. 2, the transducer(s) (10) is coated with a conductive coating (50) that enables an electrical signal to energize or drive the transducer(s) (10) causing it to emit pressure (energy) of a desired character. When a protective barrier (60) is adhered or otherwise coupled to a transducer(s) (10) it is understood to mean herein that a conductive coating (50) may exist between the protective barrier (60) and the transducer(s) (10). According to an embodiment, some or all of the conductive coating (50) may be removed from the back of the transducer(s) (10) to allow it to receive the radio frequency (RF) output from the amplifier. Moreover, according to an embodiment, an electrically conductive material (i.e., metal wire, conductive tab or spring, etc.) interfaces or is connected to the conductive coating (50) on the transducer(s) (10), and is then either electrically grounded or electrically connected back to the power amplifier to complete the circuit. This circuit is not polarity sensitive. The electrically conductive material can be attached in their reverse manner.

[0193] According to an embodiment, the transducer(s) (10) may be manufactured into various shapes and sizes according to a desired application, preferably circular in shape. Also, according to an embodiment, the transducer(s) (10) may have a diameter of various lengths, preferably about one (1) inch. By using a protective barrier (60) of the present invention, the transducer(s) (10) may have a smaller diameter and smaller surface area than that taught in the prior art without the problems of overheating and/or failing during operation, the need for a cooling mechanism to prevent the transducer(s) (10) from overheating and/or failing, and/or putting space between the protective barrier (60) and the transducer(s) (10) and/or filling that space with various cooling fluids.

[0194] Examples of electronic equipment and methods for operating or driving the transducer(s) (10) are discussed in U.S. Pat. Nos. 5,878,355 and 6,102,992 (both of which are incorporated herein by reference in its entirety, including any references cited therein). U.S. Pat. No. 5,925,966, which is incorporated herein by reference in its entirety, including any references cited therein, also provides details of the hardware necessary to operate the transducer(s) (10). Additional electronic equipment, tolerances, and methods for operating or driving the transducer(s) (10) known in the art may also be used. A variable frequency oscillator or signal generator is used to generate a high frequency wave, preferably a sine or square wave.

[0195] According to an embodiment, a preferred oscillator is a digital function generator/counter capable of producing sine, square, triangle, pulse and ramp waves. A preferred oscillator has an adjustable frequency range from about 0.025 MHz to about 12 MHz, and may be set or designed for a particular need or requirement. It preferably has variable output amplitude from 5 mV to 20 Vp-p (Volts peak to peak) being delivered to the amplifier, variable symmetry/duty cycle from 5% to 95% in the ramp or pulse mode, continuous or externally controlled outputs. This signal can then be optionally amplified using a power amplifier to increase the power to the optimum aerosol producing power. The volts peak to peak is a measure of power that is supplied to the transducer(s) (10). A direct current (D.C.) offset between −10 v to +10 v can be added to any of the output waveforms.

[0196] In one embodiment, the amplifier is a solid-state amplifier that provides up to 2500 watts of linear power with low harmonic and intermodulation distortion and peak to peak voltages of about 20 volts to about 300 volts; however the number of watts could also be increased in order to provide enough power to drive a desired number of transducers and the peak to peak voltages could also be increased, preferably about 100 watts of linear power per transducer(s) (10) with about 190 to about 230 Vp-p.

[0197] The amplified signal from the amplifier is used to operate or drive one or a plurality of transducer(s) (10), where in an embodiment each transducer(s) (10) is operated at a frequency range between about 0.025 MHz to about 10 MHz or higher, preferably between about 0.5 MHz to about 2.5 MHz, more preferably between about 1.2 MHz and about 2.2 MHz. Moreover, in such an embodiment each transducer(s) (10) has a resonant frequency between about 0.025 and about 10.0 MHz or higher. The operating frequency is the frequency at which the transducer(s) (10) is being driven or operated. The resonant frequency is the frequency of the transducer(s) (10), unloaded in air, without being adhered to the protective barrier (60) or other parts of the transducer assembly (100).

[0198] Optionally, in one embodiment, the conductive coating (50) may be applied to the entirety of the surface of each transducer(s) (10) so that it can be energized. According to an embodiment, some or all of the conductive coating (50) may be removed from the side (5) that faces away from the liquid (30) in the reservoir (40). The side (5) of the transducer(s) (10) is also the side that receives the radio frequency (RF) output from the amplifier. According to an embodiment, an electrically conductive material (i.e., metal wire, conductive tab or spring, etc.) interfaces or is connected to the conductive coating (50) on the transducer(s) (10), and is then either electrically grounded or electrically connected back to the power amplifier to complete the circuit. This circuit is not polarity sensitive. The electrically conductive material can be attached in their reverse manner.

[0199] The transducer(s) (10) is protected from chemical interaction with a liquid (30), as well as any erosion that could be caused by cavitation, by utilizing a protective barrier (60). In an embodiment, referring to FIG. 2, applying a protective barrier (60) onto the side of the transducer(s) (10) that faces the liquid (30); where the protective barrier (60) is first heated to a pliable or molten state and then applied to the transducer(s) (10). In another embodiment, referring to FIG. 3, adhering, or bonding the surface of one or more transducer(s) (10) that faces the liquid (30) with a protective barrier (60). According to an embodiment, the protective barrier (60) may be a pane or plate, and/or be made of materials such as glass, ceramic, or a polymer. Preferably the protective barrier (60) is a sheet of quartz glass. The material of a protective barrier (60) should have an effective or high chemical resistance to the liquid (30) used. The thickness of a protective barrier (60) is held to specific tolerances. In one embodiment, an adhesive, cement, epoxy, or bonding agent/compound, etc. (herein, collectively “adhesive” (70)), whose performance is unaffected and/or not adversely affected by heat, is utilized for adhering, or otherwise connecting a protective barrier (60) with a transducer(s) (10). An interface and/or connection between a protective barrier (60) and a transducer(s)(10) may also be established by other means known to those skilled in the art. Further, no liquid or other medium, other than the adhesive (70) (and optionally, a conductive coating (50)), is necessary between a transducer(s) (10) and a protective barrier (60) for the transducer(s) (10) to function properly. According to an embodiment, glass was chosen due to attributes including, but not limited to its physical and/or mechanical properties, and ability to withstand the heat generated by a transducer(s) (10) and its general ability to withstand chemical attack. The technique of adhering a transducer to a glass barrier material is taught in U.S. Pat. Nos. 4,109,863; 3,433,461; 3,729,138; and 4,976,259, each of which is incorporated herein by reference in its entirety, including the references cited therein.

[0200] According to a preferred embodiment, a transducer(s) (10) and/or a transducer assembly (100) are placed in a chemically resistant housing (20) or other chemically resistant means to hold, holdfast, secure, and/or protect the transducer(s) (10). Certain metals and plastics have demonstrated high chemical resistance to various liquids. A chemical resistant seal or O-ring (herein “O-ring”) (80) serves as a seal between the transducer assembly (100), and the liquid (30) in the reservoir (40). According to an embodiment, the O-ring (80) may be made of any chemically resistant material depending upon the composition of the liquid (30) utilized, preferably Viton®. The preferred material has the highest chemical resistance to the liquid used.

[0201] In each of the embodiments shown in FIGS. 2-5, the transducer assembly (100), including the transducer(s) (10) and the protective barrier (60), is enclosed or packaged in, assembled with, or coupled with, a housing (20). According to an embodiment, the housing (20) may be a hermitically or non-hermitically sealed or unsealed housing, or other hermitically or non-hermitically sealed or unsealed means to hold, holdfast, secure, and/or protect transducer(s) 10, that is either interfaced with the reservoir (40), or mounted to or in the reservoir (40), or positioned within the reservoir (40), or preferably coupled or attached to the bottom wall of the reservoir (40). According to an embodiment, a sealed interface exists between the protective barrier (60) and/or the housing (20) or means to hold, holdfast, secure, and/or protect the transducer(s) (10).

[0202] In one embodiment, see FIGS. 2 and 3, the O-ring seal (80) seals the interface between the protective barrier (60) and the open upper end (90) of the housing (20). In FIG. 4, the O-ring seal (80) is positioned below the protective barrier (60).

[0203] In FIGS. 5a and 5b, the transducer(s) 10 and the protective barrier (60), where the protective barrier (60) is formed and/or assembled by method (1) or (2), is molded, thermoformed, cemented, adhered, or otherwise interfaced with/to the reservoir (40), or the housing (20) or other means to hold, holdfast, secure, and/or protect the transducer(s) (10), which establishes an effective seal between the interfacing materials. Other methods known in the art can also be used to establish this interface. In an another embodiment, the surfaces within the reservoir (40), or other surfaces to which the transducer assembly (100) is coupled, interfaced, connected, or mounted, may also act or function as the housing (20) and FIGS. 2-4 are also applicable in this capacity. Finally, a sealed interface may also exist between the housing (20) or the means to hold, holdfast, secure, and/or protect the transducer(s) (10), and a wall of the reservoir (40), or other surface(s) with which it interfaces.

[0204] According to an embodiment, it is preferred that with both protective barrier (60) methods (1) and (2), when glass is used, the glass type used may be of any acid and/or alkaline resistant glass such as, for example, quartz, or Type I (borosilicate glass or Pyrex) or Type II glass as defined by the United States Pharmacopoeia. The protective barrier (60) may be any chemically resistant material. Preferably, the protective barrier (60) has a high chemical resistance to the liquid (30) used.

[0205] The selection of a material for either of the two protective barrier (60) assemblies and methods is further determined by the material's impedance properties according to known wave transmission theories. In other words, some materials are better at transmitting pressure (energy) than others. This correlates directly with the efficiency and effectiveness of the transducer(s) (10) and is represented by the maximum amount of aerosol (200) generated by the aerosol generating system (110) per unit of time. In order to maximize the energy transfer into the liquid (30), transmission coefficients for various protective barrier (60) materials are calculated by means of known mathematical formulas pertaining to the various theories of wave transmission known to those of skill in the art. The transmission coefficients are calculated and then compared and the highest transmission coefficient is chosen. Generally, the higher the energy transmitted through the protective barrier (60), the higher the aerosol (200) output. In addition, the higher the frequency, the smaller the particles. According to an embodiment, good wave transmission is achieved through the use of a quartz glass or a borosilicate glass protective barrier (60).

[0206] The thickness of the material of the protective barrier (60) is another factor that influences the efficiency and effectiveness of the transducer(s) (10) or the total amount of or size of aerosol (200) the transducer(s) (10) is able to generate. This relates to the fact that operational frequencies will dictate selected glass thicknesses, thinner glass being selected with higher frequencies. These higher operational frequencies produce smaller droplet sizes. In the first protective barrier method, the protective barrier (60) is either formed or applied to the proper thickness. If the thickness of the protective barrier (60) is not within specifications, the protective barrier (60) may be further processed or machined to achieve the proper thickness. The second protective barrier method involves adhering, or otherwise connecting the protective barrier (60), which may be processed or machined to the proper thickness, with the transducer(s) (10). In both methods, the thickness of the protective barrier (60) is controlled to tight tolerances in order to control its transmission coefficient.

[0207] It was thought in the prior art that the optimum protective barrier thickness was equal to or about one-half (½) or any multiple of one-half (½) of the wavelength of the transmitted pressure (energy) wave. According to the prior art, at this thickness, the protective barrier material looks acoustically invisible and roughly twenty percent (20%) of the energy emitted from the transducers is being transmitted into the liquid beyond the protective barrier.

[0208] However, according to an embodiment of the present invention, it has been found that the transmission of energy through a material can be further optimized or enhanced if the thickness of that material, is between about 0.001 inches and about 0.125 inches, wherein the thickness is not n/2 or about n/2 of the wavelength of a transmitted pressure (energy) that is generated by the transducer(s) (10), wherein n is any integer. Without being limited to the mechanism, it is believed that roughly seventy percent (70%) of the energy emitted from the transducer(s) (10) may be transmitted into the liquid (30) beyond the protective barrier (60) with the thicknesses of the present invention, which is significantly higher than the 20% emitted from the protective barrier (60) with a prior art thickness of one-half (½) or any multiple of ½ the wavelength. Without being limited to the mechanism of action, the material of the protective barrier (60) may actually maximize the transmission coefficient of the pressure (energy) and thus increase the efficiency and effectiveness of the aerosol (200) output of the transducer(s) (10), in addition to protecting the electrode material. A preferred material of the protective barrier (60) may be glass, more preferably quartz glass.

[0209] Based upon an embodiment, the invention gave rise to unexpected results, including, but not limited to a significant increase in aerosol (200) output, smaller aerosol (200) particle size, and more energy being transferred to the liquid (30). Additionally, in an embodiment of the apparatus and methods of protecting a transducer(s) (10), a cooling system to prevent the transducer(s) (10) from burning or otherwise failing at various operating frequencies is not necessary. For example, U.S. Pat. No. 4,109,863, which is incorporated herein by reference in its entirety, including the references cited therein, requires a means for circulating a fluid over the transducer and glass for cooling and stabilizing a transducer. However, according to U.S. Pat. No. 4,976,259, this method has the undesirable effect of acoustically dampening the back side of the transducer which reduces the efficiency of the nebulizer system.

[0210] When calculating the optimum thickness of the protective barrier (60) in an embodiment of the present invention, the following are considered: (1) operating frequency; (2) the specific natural frequency of the transducer(s) (10); (3) the type of protective barrier (60) material; (4) the thickness of the protective barrier (60); (5) optionally, a suitable adhesive/bonding agent (70); and (6) an acceptable and optimum level of aerosol (200) by sweeping the transducer assembly (100) with a range of frequencies and power to find the desired aerosol (200) output.

[0211] According to an embodiment, once the transducer assembly (100) is assembled it can be operated at a range of frequencies. The thickness of the protective barrier (60) may range depending upon the operating frequency of the transducer(s) (10). According to an embodiment, the thickness of the protective barrier (60) ranges from about 0.001 inches to about 0.125 inches, wherein the thickness is not equal to or about n/2 of the wavelength of pressure (energy) generated by the transducer(s) (10) at a frequency between about 0.025 MHz and about 10 MHz, wherein n is any integer, preferably a thickness between about 0.026 inches and about 0.070 inches at a frequency between about 0.5 MHz and about 2.5 MHz, more preferably a thickness between about 0.030 inches and about 0.060 inches at a frequency between about 1.2 MHz and about 2.2 MHz, and even more preferably a thickness between about 0.029 inches and about 0.042 inches at a frequency between about 1.2 MHz and about 2.2 MHz.

[0212] Empirical testing for hydrogen peroxide and peroxyacetic acid in solution; and water determined that the transducer(s) (10) generated the greatest amount of aerosol (200) when the liquid (30) above them was maintained at a temperature above about 80° F., preferably about 105° F. This is most likely due to the reduction of the surface tension of the liquid (30) as its temperature increases.

[0213] According to an embodiment, the liquid (30) may not have to be at least 80° F. for effective performance in certain circumstances where high aerosol output is not necessary, or the liquid already has a low enough surface tension to achieve a desired result. Further, according to an embodiment, any variations in the temperature may be made to optimize the aerosol (200) output based upon the type of liquid (30) used and the results desired by the user.

[0214] According to an embodiment, a protective barrier (60) for an aerosol (200) producing transducer(s) (10) has a thickness between about 0.001 inches and 0.125 inches, wherein the thickness is other than equal to or about n/2 of the wavelength of the transmitted pressure (energy) waves that are generated by the transducer(s) (10), wherein n is any integer. Thus, the thickness of the protective barrier (60) as described above permits the transducer(s) (10) to operate effectively to provide a high volume small aerosol (200) particle output, which is preferred, or any other desired output without the need for space between the transducer(s) (10) and the protective barrier (60) or a cooling mechanism.

[0215] Most preferably, in accordance with one aspect of the present invention, it has been found that the transmission of energy through a material can also be optimized if the thickness of that material, in this case glass, is about one quarter (¼) or any multiple of one quarter (¼) of the wavelength of the transmitted pressure waves generated at the natural resonant frequency of the transducer. The barrier material in this case will not only look acoustically invisible but will also maximize the transmission coefficient of the pressure waves and thus increase the efficiency and effectiveness of the transducer's aerosol output. The gain in power transmission for a particular transducer can, without limitation, increase from approximately 20%, for a barrier sized at one half (½) of the wavelength of the transmitted pressure waves generated by the transducer at the natural resonant frequency of the transducer, to approximately 71% for a barrier sized at one quarter (¼) of the wavelength of the transmitted pressure waves generated by the same transducer at the natural resonant frequency of that transducer.

[0216] Testing was conducted in the laboratory to determine what glass thickness when adhered to the transducer would generate the maximum amount of aerosol. Transducers with an adhered quartz glass thickness of 0.096 inch and 0.125 inch were tested first, and both suffered damage when the heat from operating the transducer burned the epoxy, which is used to adhere the glass to the transducer. This was evidence that a thinner glass material was needed in order to, without limitation, more effectively transmit the energy and heat produced by the transducer into the liquid above the glass. A quartz glass barrier of about ¼ wave length of the propagated pressure wave for a 1.5 Mhz transducer, or 0.036 inch, was manufactured, and its output greatly exceeded the target of 800 milliliters of aerosolized liquid per hour with an average output of 1500 milliliters per hour, as shown in the data in Table 1, along with data illustrating the effectiveness of barriers having other thicknesses with the 1.5 Mhz transducer.

[0218] As a result of this testing, it has recently been determined that the transducer incorporating the barrier provides the best results when the thickness is calculated as a multiple of about n/4 of the wavelength of the natural resonant frequency (unloaded in air) of the transducer. The transducer including the barrier having this calculated thickness must also be operated at an operational frequency that is greater than the natural resonant frequency of the transducer by between about 4% and about 60% of the natural resonant frequency of the transducer. This calculation of the barrier thickness and the resulting operational frequency to optimize the aerosol generation by the transducer can be utilized for transducers having natural resonant frequencies in the range of 0.5 Mhz to 8.0 Mhz.

[0219] Further empirical testing in the laboratory for a particular transducer also determined that the actual effective range of glass thickness for aerosol output of a transducer having a natural resonant frequency of 1.5 Mhz was minus 0.010 inches and plus 0.024 inches, from 0.036 inches, or the calculated barrier thickness of one quarter (¼) of the wavelength of the transmitted pressure waves from the 1.5 Mhz transducer. It was also found that this asymmetrical range is, without limitation, strongly correlated with the admittance vs. frequency sweeps for transducers with glass barriers of this type. These sweeps include, but are not limited to, showing two distinct and separate peaks or amplitudes that both exhibit a curve that has a pronounced or sharp drop to the right of each amplitude. Thus, the operation and effectiveness of the aerosol generator including the transducer (10) including the barrier (60) can also be increased by utilizing a barrier having a thickness in this range above and below the calculated barrier thickness at approximately n/4 for the wavelength of the transducer at its natural resonant frequency.

[0220] Also, empirical testing determined that the transducers generated the greatest amount of aerosol when the liquid above them was maintained at a temperature above 80 degree Fahrenheit. This is most likely due to the reduction of the liquid's surface tension as its temperature increases.

[0221] Therefore, in the present invention the optimum glass barrier thickness for the aerosol producing transducer, is approximately one quarter (¼) or approximately any multiple of one quarter (e.g., 0.5/4, ¼, 1.5/4, 2.5/4, ¾, 3.5/4, 5/4 . . . or n/4 where n=about any odd number, or the result of any mathematical operation) but not equal or about equal to any multiple of n/2 of the wavelength of the transmitted pressure waves from the transducer as calculated by the formula:

[0222] $\lambda \left(\mathrm{wavelength}\right)=\frac{c\left(\mathrm{speed}\mathrm{of}\mathrm{sound}\mathrm{in}\mathrm{the}\mathrm{selected}\mathrm{material}\right)}{f\left(\mathrm{natural}\mathrm{resonance}\mathrm{frequency}\right)}$
when the transducer is operated at an operation frequency of up to 60% above, preferably between 4% and 60% above, more preferably between 9% and 50% above or about 10% to about 45% above, and most preferably between about 18% and 27% above the natural resonant frequency of the transducer.

[0223] Additionally, the transducer can be constructed with a barrier within a range of minus 0.010 inches (−0.010 inches) and plus 0.024 inches (+0.024 inches) from the calculated optimum barrier thickness, where the n/4 multiple of the wavelength is not equal to or approximately equal to any multiple of one half (½) of a wavelength. These methods in their entirety can be used with any transducer with a natural resonant frequency, unloaded in air, between 0.5 MHz to 8.0 MHz.

[0224] Specifically, maximum aerosol output is achieved with a glass thickness within the range of minus (−) 0.010 inches and plus (+) 0.024 inches, from the optimum thickness calculated as the multiple of n/4 of the wavelength of the transmitted pressure waves, with this multiple more preferably being a multiple where n=an odd number (i.e., 1, 3, 5, 7, 9, etc.) and where n/4 is not equal to any multiple of n/2. More preferably, n is from 1 to 9. In a particularly preferred embodiment, the calculated glass barrier thickness is 0.036 inches (0.036-0.010 to 0.036+0.024 inches).

[0225] In a preferred embodiment, the transducers utilized with the barriers having these thicknesses have a natural resonant frequency, unloaded in air, between 1.25 to 1.65 MHz and their operating frequency range in liquid is between 1.71 to 2.00 MHz.

[0226] In one embodiment, the liquid depth above the transducers can range from 0.5 to 5.0 inches. In addition the liquid in the tank above the transducers should be maintained at a temperature of 80 degree Fahrenheit or greater in order to maximize the amount of aerosol that is generated.

[0227] When utilizing a barrier (60) having a thickness in this calculated range, the transmission of energy from the transducer (10) through the barrier (60) to the liquid (30) is increased from around 20% to around 70%. This increased transmission percentage greatly reduces the degradation of the bond formed by the adhesive (70) binding the barrier (60) to the transducer (10), allowing the adhesive (70) to hold the barrier (60) in place during operation of the transducer (10).

[0228] According to an embodiment, many depths of the liquid (30) above the transducer(s) (10) may be used; preferably the depth of the liquid (30) above the transducer(s) (10) is from about 0.25 inches to about 8.0 inches, and more preferably a depth of about 1.25 inches. However, it may be possible to operate the invention at levels below 0.25 inches if lower power and/or frequencies are used. Moreover, according to an embodiment, the liquid (30) may be maintained at any temperature necessary to achieve the desired results based upon the preferences of the user or the type of liquid used. Preferably any liquid (30), such as peroxyacetic acid and hydrogen peroxide, in the reservoir (40) may be maintained at a temperature of about 80° F. or greater in order to maximize the amount of aerosol (200) that is generated. However, the temperature of the liquid (30) may vary depending upon such parameters as the desired aerosol (200) output, the type of liquid (30) used, and the surface tension of the liquid (30).

[0229] Referring to FIGS. 6-15, there are shown embodiments of an aerosol generator (110) according to the present invention. The reservoir (40) contains a volume of liquid (30), the level of which is controlled by a dam (or weir gate) (120) operatively associated with a supply pump (130) and a supply line (140) to maintain the level of the liquid (30) at a preferred level above the transducer(s) (10) mounted on the bottom wall of the reservoir (40). The transducer(s) (10) may be individually mounted in separate housings (20), as shown in one of the embodiments of FIGS. 2-4, or they may all be coupled to a common protective barrier (60) wall and appropriately sealed from contact with the liquid (30). It has been found that efficiency of aerosol (200) generation is enhanced by heating the liquid (30) to at least 20° F. above ambient, preferably to at least about 80° F.; however the temperature may vary depending upon the type of liquid (30) used. A heater element (150) is coupled with a liquid supply sump (160) to control the temperature of the liquid (30). The aerosolized liquid (200) is delivered to the space to be treated via an exit orifice (170) of the aerosol generator (110) to which suitable piping (not shown) may be attached for delivery. A blower (180), fan, or other source of pressurized air generates the air flow necessary to deliver the aerosol (200), all in a manner well-known in the art.

[0230] According to an embodiment, the transducer(s) (10) and the protective barrier (60) may be sized to provide an optimized resonant frequency that is operative when driven or operated at an operating frequency in the range of about 0.5 MHz to about 2.5 MHz. This large range is due to the appearance of two separate operating ranges that are apparently unique to the transducer assembly (100). For example, using a transducer(s) (10) having a resonant frequency of about 1.40 MHz to about 1.48 MHz with a protective barrier (60) thickness of about 0.036 inches, driven at an operating frequency ranging from about 1.78 MHz to about 1.98 MHz will most commonly show a maximized aerosol (200) output of at least about 1,000 ml per hour of the liquid (30). A second effective operating frequency with lower output is noted at about 1.2 MHz. According to an embodiment, for certain applications where the volume of the space to be treated is small, an output of at least 1,000 ml/hr may not be necessary. In such a situation, the transducer(s) (10) may be operated or driven with various combinations of power or volts peak to peak, and frequencies that result in the generation of lower aerosolized (200) liquid output. For example, in the treatment of a space the size of about a small glove box or the like, an output of 10 ml/hr or less may be adequate.

[0231] The apparatus and methods of the present invention may yield aerosol (200) droplets of various sizes. According to an embodiment, they may yield aerosol (200) droplets with a defined size distribution of mostly less than about one (1) microns in diameter, without being limited to a mechanism it is believed this allows the droplets to behave more like a gas with respect to Brownian movement and diffusion. The size of the aerosol (200) droplets may be adjusted upward or downward according to the desired results. The small aerosol (200) droplet size enables the drops to penetrate small cracks and crevices, and apply very thin films on surfaces. In addition, the aerosol (200) may effectively reach and disinfect areas of contamination and areas of otherwise limited accessibility. Any means to create an aerosol (200) with droplets less than about 10 microns in size could be used in the present invention. Larger particles will by their nature cause less penetration and decrease the effectiveness for many but not all possible application. Thus, the present invention may generate predominantly submicron size droplets or sizes may be controlled for a desired result. According to an embodiment, the average particle size may range from less than one micron to about 10 microns, preferably less than about 5 microns, more preferably less than one micron, and even more preferably about 0.68 microns.

[0232] According to an embodiment, multiple transducer(s) (10) are typically used to provide an output volume of aerosolized liquid (200) sufficient to rapidly treat a large enclosed space. In such a case, the transducer(s) (10) may be mounted individually, or a plurality of transducer(s) (10) may be coupled to a single protective barrier (60), with one or more of the protective barrier (60) being coupled, mounted on or in a reservoir (40), or positioned within a reservoir (40) with an appropriate coupling device. Multiple transducer(s) (10) may be coupled to a single protective barrier (60) at varying distances apart, preferably between at least about 0.25 inches apart, more preferably about 0.75 inches apart.

[0233] The present invention includes apparatuses and methods related to the generation and delivery or application of an aerosol (200) of liquid (30) that is created with ultrasound or piezoelectric transducers (10), for a wide range of uses including but not limited to: (a) the sanitization, disinfection, high-level disinfection, or sterilization of one or more areas and the surfaces in those areas, (b) the delivery of other types of liquid (30) in the form of an aerosol (200) for various purposes, such as, but not limited to, the application of pesticides, moisture, medication, particles, or nano sized or smaller machines, to one or more areas and surfaces within those area(s). The attributes of the area to which the aerosol (200) is delivered or applied can vary and can include, but is not limited to: spaces that are open, enclosed, semi-enclosed, unsealed, sealed, or partially sealed. It is preferred, without limitation, that the area in which the aerosol is administered in the present invention is enclosed and effectively sealed to prevent the leakage of the aerosol from the enclosed area. Referring initially to FIGS. 7-9, the apparatus (215) can be operated either outside, partially inside and partially outside, or within the area in which the aerosol is deployed or administered.

[0234] Preferably and without limitation, an aerosol (200) of a liquid is first generated and/or administered in or into the intended or targeted area (210). This area can also, without limitation, contain one or more objects and surfaces. The aerosol (200) may have various mass concentrations, which is the mass of particulate matter in a unit volume of aerosol. The number concentration of the aerosol (200) may also vary. The number concentration is the number of particles per unit volume of aerosol. It is preferred without limitation, that the aerosol (200) has a higher rather than lower mass concentration of droplets. It is preferred without limitation, that the aerosol (200) has a higher rather than lower number concentration of droplets. The aerosol (200) droplets may be of various sizes. The aerosol may be created from any liquid containing one or more chemical(s) of any kind, or a combination of liquids each containing one or more of any kind of chemical(s).

[0235] According to an embodiment, it is preferred, without limitation, that the aerosol (200) is a ten micron to submicron size droplet. The fog or aerosol can, without limitation, consist substantially of submicron aerosolized droplets. The fog or aerosol can, without limitation, have characteristics that include but are not limited to (1) a faster anti-pathogen, toxin, fungal, sterilization, disinfection, or sporicidal effect than the non-aerosolized liquid; (2) the ability to penetrate and disinfect, high-level disinfect or sterilize, areas and surfaces where aerosols comprised of droplets greater than two microns may not work; (3) resists coalescence and condensation typical of larger size droplets; and/or (4) dense packing of small particles provides an unprecedented droplet surface area per volume of gas.

[0236] The apparatus and methods described in the present invention can pertain to any aerosol generator or aerosol generator that uses ultrasound or piezoelectric transducers (10). They may also pertain to an aerosol producing apparatus as described in the present invention, including the specifics of the present invention hereto mentioned. This apparatus is further described with the attributes discussed below. Referring to FIGS. 11-13, 16-32 and 35-36, which shows the preferred apparatus (215) in the present invention, the apparatus (215) generates aerosol (200) by operating one or more piezoelectric transducers (10), in parallel or series. One or more amplifiers (230) may be used. It is preferred, without limitation, that the transducer(s) (10) receive signal or power from at least one amplifier(s) (230), and that multiple transducers are operated in parallel. One or more transducers (10) are located under the surface of the liquid (30) in one or more reservoirs, chambers, basins, or tanks (40) (herein referred to as reservoir(s)) at an effective depth and orientation. The reservoir(s) (40) may be made from any material that is compatible, and suitable for use with the liquid (30). The aerosol (200) generated by operation of the transducer(s) (10) forms above the surface of the liquid (30) in the reservoir(s) (40) and may be transferred from the reservoir(s) (40) to one or more targeted area(s) or chamber(s) by one or more fan(s) or blower(s) or other source of pressurized air or gas (herein referred to as blower(s)) (180).

[0237] The air and aerosol (200) can, without limitation, flow from the aerosol generator (110) to the one or more targeted area(s) (210) through one or more pipe(s) (220). It is preferred, without limitation, that only one reservoir (40) in which the transducer(s) are located is utilized in the apparatus (215) of the present invention. The reservoir(s) (40) can be, without limitation, unenclosed, semi-enclosed, or enclosed. It is preferred, without limitation that an enclosed reservoir(s) is utilized, and is built in a manner known in the art so that air from a fan or blower can flow through it and carry the generated aerosol out of the reservoir and away from the apparatus (215).

[0238] The air and aerosol can flow through a zig-zag path or be directed around one or more baffle plates (250), positioned anywhere in the path of the air/aerosol as it moves from the reservoirs in which the transducers are located to the exterior of the apparatus (215). The use of the aforementioned baffle plate(s) is taught at (col. 4, line 18-22) of U.S. Pat. No. 4,366,125 (Kodera et al., 1980), which is incorporated herein by reference in its entirety, including any references cited therein.

[0239] If needed or desired, the apparatus (215) in the present invention can be connected in a closed loop or system as shown in FIG. 9, to the targeted area(s) or chamber(s) (210), as taught at (pg. 3 col. 23-34) of G.B. Patent No. 1,128,245, (Rosdahl et al., 1968), which is incorporated herein by reference in its entirety, including any references cited therein. The air and aerosol (200) discharged from the apparatus (215) in the present invention, can be delivered with one or more pipe(s) or conduit(s) (220). The air and aerosol (200) may also be recirculated through one or more return pipe(s) or conduit(s) (240) from the targeted area(s) or chamber(s) (210), back to the air/gas intake(s) (255) for the fan(s) or blower(s) (180). Throughout the present invention, the terms “pipe”, “pipes”, or “piping” includes pipes, ducts, conduits, tunnels, and the like. In addition, the aforementioned closed loop or system can have, without limitation, one or more air/gas valve(s) (260) that can allow non-filtered or filtered inbound air/gas into the said closed loop or system, as well as one or more air/gas valve(s) (265) that can allow non-filtered or filtered inbound air/gas out of the said closed loop or system. The air/gas that is supplied via the inbound air/gas valve(s) (260) can be supplied, without limitation, from the atmosphere surrounding the apparatus (215) and the air/gas that passes through the outbound air/gas valve can be, without limitation, vented into the atmosphere surrounding the apparatus (215). The filter(s) (265) can be or consist of any filter design, material, or other effective means for the intended application. The filter or its application can include, without limitation, what is taught in U.S. Pat. No. 4,512,951 (Koubek et al., 1983), and incorporated herein by reference in its entirety, including any references cited therein. The said air/gas valves (260) or (265) can, without limitation, be electronically or electrically opened and closed in a manner known to those skilled in the art, and can be positioned or interfaced in numerous places in the closed loop or system. The outbound air or aerosol can, without limitation, be filtered with one or more filters (270) to prevent any employees or operators from being exposed to any vented aerosol, and to comply with any worker safety or environmental safety guidelines or regulations.

[0240] The liquid capacity of the reservoir(s) (40) in which the transducer(s) (10) are located can vary, but the liquid level is at least at a suitable depth or level so that the transducer(s) (10) can effectively and safely operate. The reservoir(s) (40) in which the transducer(s) (10) are located is connected to one or more tanks(s) (280) that are connected and feed liquid to the reservoir(s) (40). The tank(s) (280) that feeds or supplies the liquid (30) can be of any size, geometry, shape, and capacity, and may be made from any material that is compatible, and suitable for use with the liquid (30). The tank(s) (280) may be non-ventilated, or ventilated in one or more places in a way know to those skilled in the art, and the means to ventilate the tank(s) (280) can incorporate a suitable filter. The filter(s) are any suitable filter for the intended application, and are known to those skilled in the art. It is preferred, without limitation, that the apparatus (215) in the present invention has only one tank (280) that feeds or supplies liquid to the reservoir (40) in which the transducer(s) (10) are located. However, a means known to those skilled in the art can be provided so that additional tanks (280) can be attached to or interfaced with the apparatus (215) and feed liquid to either the main feed or supply tank (280) or the reservoir(s) (40) in which the transducers (10) are located.

[0241] The one or more tank(s) (280), that feeds or supplies the liquid (30) to the reservoir(s) (40) in which the transducer(s) (10) are located, can be filled in various ways, including, but not limited to, directly pouring a liquid that is either mixed or unmixed into one or more feed interface(s) (285) or pipe(s) (295) that are connected to the said tank(s) (280). Without limitation, the feed interface(s) (285) or pipe(s) (295) orifices can have: (a) a funnel or be shaped like a funnel to make pouring the liquid (30) into the feed interface(s) (285) or pipe(s) orifices (295) easier, (b) a tray or bowl located under or around the outer edges of the feed interface(s) (285) or pipe(s) orifices (295) to catch any spilled liquid (30) in a manner known in the art. Without limitation, the apparatus (215) in the present invention can also be designed and constructed, in a manner that is known to those skilled in the art, so that it can interface with one or more disposable or reusable containers or cartridges (herein referred to as “cartridge”, “cartridges”, or “cartridge(s)”) (290) used to supply, fill, or refill the apparatus (215) with liquid (30). Without being limited, the cartridges (290) and apparatus (215) can be designed in a manner known in the art, so that only unique, special, or proprietary cartridges (290) may be used. The means to interface the cartridge(s)s with the apparatus (215) so that the liquid is effectively and safely transferred from the cartridges (290) into the said reservoir(s) (40), is known to those skilled in the art.

[0242] The reservoir(s) (40) in which the transducer(s) (10) are located can also have one or more valves (300) that can, without limitation, control the flow of liquid (30) from the tank(s) (280) that feed or supply the said reservoir(s) (40). Without limitation, the valve(s) (300) can be connected to one or more sensor(s) (305) or PLC(s) (315) which are known to those skilled in the art, that can cause the valve(s) (300) to close or open and allow liquid (30) to flow into the reservoir(s) (40) in which the transducer(s) (10) are located when the liquid (30) level or depth in the reservoir(s) (40) reaches a specified level. The depth or level of the liquid (30) causing the valve (300) to open can vary. The sensor (305) can include, but is not limited to a float switch. The valve (300) can include, but is not limited to, a solenoid valve. However, it is preferred in the present invention that at least one float-valve is used, which consists of a valve (300) that is mechanically or electrically opened or closed by the movement of a float which acts as the sensor (305).

[0243] The reservoir(s) (40) in which the transducer(s) (10) are located, can have one or more float switch(s) or other sensor(s) (305) that can cause the apparatus (215), the PLC, (315), HMI (320), or any other parts or components, to enter a fault/error mode or completely shut down if the depth of the liquid (30) exceeds a certain specified depth or level. The float switch or other sensor(s) (305) is actuated and communicates or is connected to suitable circuitry, all in a way known to those skilled in the art, to cause the apparatus (215), the PLC, (315), HMI (320), or any other parts or components to shut down or enter a fault or error mode when the depth or level of liquid (30) exceeds a specified depth. The positioning of the float switch(s) or other sensor(s) (305) can vary inside the reservoir(s) (40). It is preferred in the present invention that at least one float switch (305) is utilized for this purpose.

[0244] A float switch or other liquid level sensor(s) (305) can also be used to detect and communicate or is connected to suitable circuitry, all in a way known to those skilled in the art, to cause the apparatus (215), the PLC, (315), HMI (320), or any other parts or components to shut down or enter a fault or error mode when the depth or level of liquid (30) drops below a certain point or depth in the reservoir(s) (40) in which the transducer(s) (10) are located. This can, without limitation, prevent the liquid (30) in the reservoir(s) (40) from dropping to an ineffective or unsafe depth or level. This condition may occur from situations including, but not limited to, a valve (300) that is stuck closed from a tank (280) that supplies the liquid, or a leaking tank. The positioning of the float switch(s) or other sensor(s) (305) can vary inside the reservoir(s) (40). It is preferred in the present invention that at least one float switch or liquid level sensor (305) is utilized for this purpose.

[0245] The fan or blower (180), or other source of pressurized air or gas, may also be constructed from any suitable material that is not affected by the chemical action of the liquid (30). Suitable materials may include PVC, polypropylene, and stainless steel, but other suitable materials may also be used. The blower(s) can either push or pull the air or gas, as well as aerosol, through, or across, the chamber, reservoir, or other area in which the aerosol is generated to remove it from the apparatus (215). The blower(s) (180) or other source of pressurized air or gas can move any quantity of air at any speed sufficient for the intended application. The blower(s) (180) can also be chosen, without limitation, to meet the following variables that include, but are not limited to: (a) the quantity of aerosol that is being generated, (b) the amount of surface disruption that it might create and its effect on aerosol production, (c) the desired quantity of aerosol that is evacuated from the apparatus (215), (d) the geometry and volume of the targeted area, (e) the geometry and volume of any conduit or piping that may be used to deliver the aerosol, (f) the manner and effectiveness in which the targeted area is sealed, (g) and uniformity of the aerosol (200) deployment or administration in or into the targeted area. Without limitation, the blower(s) (180) can be controlled by the PLC (315) in a manner known in the art.

[0246] Certain applications will require lower airflows, while other applications will require higher airflows. It is preferred, without limitation, that the blower (180) used in the present invention is a centrifugal fan or blower and that it is constructed using polypropylene for a housing and impeller, and 316L stainless steel for its drive shaft. It is further preferred, without limitation, that the fan or blower (180) pushes air/gas and aerosol out of the chamber, reservoir, or other area in which the aerosol is generated. The housing or enclosure for the blower(s) (180) can be plumbed to remove any excess liquid that may collect as the blower is operated. It is preferred, without limitation, that the housing or enclosure for the blower(s) (180) is plumbed in the present invention.

[0247] According to the prior art established by U.S. Pat. No. 4,366,125 (Kodera et al., 1980), and the book titled, “Aerosol Technology” by William C. Hinds (1982), the liquid (30) utilized in the present invention can be heated by using three different means, or a combination of one or more of the three different means. First, the liquid (30) can be heated inside the reservoir(s) (40) in which the transducers (10) are located, by utilizing one or more means to provide heat (150) that is either in direct contact with the liquid or interface with the walls of the reservoir(s) (40), or both. Second, the liquid (30) in the reservoir(s) in which the transducer(s) (10) are located can also be heated by circulating it through one or more means to heat (310) the liquid, and back into the reservoir(s) (40). Third, the liquid can be heated as it flows from one or more tank(s) (280), that feeds or supplies the liquid (30) to the reservoir(s) (40) in which the transducers (10) are located.

[0248] In addition, and without limitation, the one or more valves (300) that control the flow of the liquid (30) can be electrically or electronically signaled to open, close, or semi-open, in a manner known in the art. A pump or other means (130) can move the liquid (30) intermittently or can continuously circulate the liquid (30) from the reservoir(s) (40) in which the transducers (10) are located, back to the aforementioned tank(s) that feeds or supplies the liquid (30) to the reservoir(s) (40). Without being limited, the valves (300) in this situation can be maintained in a semi-open or open position unless signaled or caused by some other means including, but not limited to, an electrical signal from an electronic controller or programmable logic circuit (315), to close, for various reasons including, but not limited to, a pump (130) failure that would cause the reservoir(s) (40) in which the transducers (10) are located to overflow.

[0249] It is preferred, without limitation, that one or more means (150) for heating the liquid (30) is located inside or partially inside the reservoir(s) (40) in which the transducers (10) are located, and is installed into or interfaced with the said reservoir(s) (40) in a way that is known to those skilled in the art. It is further preferred, without limitation, that the said means for heating (150) the liquid (30) is a cartridge heater.

[0250] The three aforementioned means to heat the liquid (30) are known to those skilled in the art, and are sufficiently designed and built for their intended purpose, and may be constructed from any material that is compatible, and suitable for use with the liquid (30). Properly heating the liquid (30) to the desired, or efficacious temperature can involve issues such as, but not limited to, the type of heater(s) that would be effective, the number of heater(s) used, the heat output of each heater, the duration and timing of operation for each heater, the intensity of the heat generated, the materials of construction, and are known to those skilled in the art. In addition, the pump or other means (130) used to circulate the liquid (30) provides the necessary flow rate or pumping capacity, which can vary, for the intended application and may be constructed from any material that is compatible, and suitable for use with the liquid (30).

[0251] As best shown in FIG. 10, the apparatus (215) in the present invention can be controlled, without limitation, by one or more programmable logic circuit(s) (PLC) or other suitable circuitry, computer, electrical system, or electronics (herein called “PLC or PLC(s)”) (315), and related software and program(s), known to those skilled in the art. Without limitation, one or more human machine interface(s) (HMI), screen, or other means to interact with the operator (herein called “HMI or HMI(s)”) (320), and related software and program(s), known to those skilled in the art, can be used, without limitation, to convey information as well as allow the operator to set parameters or enter commands. The PLC (315) and HMI (320) can be configured or programmed to enable the operator to, without limitation, enter information into the HMI (320) or PLC (315), program the HMI (320) or PLC (315), or execute command(s). The HMI (320) or PLC (315) can also provide a means, without limitation, for the operator to choose a specific volume or area for the apparatus (215) to administer or deploy the generated aerosol, or choose a specific aerosol deployment time. The HMI (320) or PLC (315) can be programmed to associate one or more values for volumes or areas chosen by the operator with specific aerosol deployment time(s). The menus, software, and programming for the HMI (320) or PLC (315) can be customized for each customer's needs and may include, without limitation, providing the operator with one or more menus that presents a plurality of room numbers or other attributes that the operator can choose, and each room number or attribute is associated with operational parameters and variables such as, but not limited to, liquid temperature(s), volume of the room or targeted area, and the total cycle time that the apparatus (215) would need to operate in order to efficaciously and effectively deploy the aerosol into the chosen room or targeted area. In addition, and without limitation, the HMI (320) or PLC (315) can have a provision in its program(s) or software to change the operational parameters that effect the performance of the apparatus (215) or process due to temperature and humidity values that are either reported to the HMI (320) or PLC (315) by the operator or by automated means known to those skilled in the art. The PLC (315) can, without limitation, include any PID, PID tuning, or PID auto tuning, functions, attributes, or activities. The PLC (315) can, without limitation, control and maintain the temperature of any liquid (30) to any desired or necessary temperature in any reservoir(s), including, but not limited to, the reservoir(s) (40) in which the transducers (10) are located. Without limitation, the PLC (315) can control liquid (30) temperature, by controlling one or more part(s) and component(s) of the apparatus (215) such as, but not limited to any: (a) blower(s), (b) valve(s), (c) heater(s), (d) pump(s), (e) amplifier(s) or other means to power or control the transducer(s) (10), or (f) any means used to cool the liquid (30). Without limitation, the PLC (315) can control liquid (30) temperature, by controlling or communicating with one or more part(s) and component(s) of the apparatus (215) such as, but not limited to any: (a) any thermostat or temperature controlling device (b) blower(s), (c) valve(s), (d) heater(s), (e) pump(s), (f) amplifier(s) or other means to power or control the transducer(s) (10), or (g) any means used to cool the liquid (30).

[0252] The PLC (315) can also, without limitation, send or receive or detect any signal, current, or other modes of communication, or their absence, from various components or parts of the apparatus (215) or components or parts related to effective operation of the apparatus (215). These signals, current, or other modes of communication, or their absence, can without limitation, be used by the PLC (315) to, control the apparatus (215) or its components and functions, or monitor the function or status of components or parts of the apparatus (215). Without limitation, the signals, current, or other modes of communication, or their absence, sent by the PLC or to the PLC, can result from the direct or indirect connection and communication of the PLC (315) with components such as, but not limited to, any: (a) current sensor(s) (325), (b) liquid level sensor(s) (305), (c) electronics that power, operate, or control, the transducer(s) (10) (herein referred to as “drive electronics”) (645), (d) air/gas temperature sensing thermocouple(s) (650) or other means to sense air/gas temperature, (e) liquid temperature sensing thermocouple(s) (820) or other means to sense liquid temperature, (f) humidity sensor(s) (335), (g) valve(s) (300) (660) that control the flow of liquid, (h) valve(s) (260) (265) (210) (815) (775) that control the flow of any air/gas or aerosol that can flow into or out of a targeted area, (i) wireless transceiver(s) (340) or other signal transmitter(s)/receiver(s).

[0253] One or more air/gas temperature sensor(s) (650) can be placed in various locations inside or outside of the apparatus(s) (215). It is preferred, without limitation, that at least one air/gas temperature sensor is positioned in any enclosure or NEMA or IP rated sealed enclosure (345) that has the potential for its internal atmosphere (740) to increase in temperature due to the operation of the apparatus(s) (215). The PLC(s) (315) can, without limitation, use the input from any sensors including, but not limited to, liquid temperature, air/gas temperature, or any other temperature sensor(s), to control activities such as, but not limited to, heating of any liquid and any related activities (30), cooling of any liquid and any related activities (30), or cooling of any part(s), component(s), or atmosphere(s) (740) in any enclosed space(s) found in the apparatus(s) (215) and any related activities. Any valve(s) utilized in the present invention can also, without limitation, be manually controlled and operated, or electronically controlled and operated by one or more PLC(s) (315) in a manner known to those skilled in the art. It is preferred, without limitation, that any electrically or electronically controlled valve(s) that can be utilized for various purposes and at various locations, are solenoid valve(s).

[0254] The drive electronics (645) can include, but is not limited to, the following parts or components: (a) one or more power supply(s), (b) one or more signal or waveform generator(s) (herein referred to as “signal generator(s)”) (c) one or more amplifier(s), or (d) other electronic equipment, components, parts, and methods for operating or driving the transducer(s) (10) known in the art may also be used. In addition, one or more sensors or means (1045) for determining the liquid level or the amount of liquid in the reservoir(s) (40) in which the transducers (10) are located or in the tank(s) (280) that feeds or supplies liquid (30) to the said reservoir(s) (40), can also be connected or communicate with the PLC (315), in a manner known in the art, and can enable the PLC (315) to determine if a sufficient quantity of liquid is available for any application time or volume of space chosen by the operator.

[0255] More specifically, the various signals, current, or other modes of communication, or their absence, received or detected by the PLC (315) can be used, without limitation to determine if the apparatus is functioning or operating within acceptable operational parameters. If the apparatus (215) is not operating within acceptable operational parameters, the PLC (315) can shut down, without limitation, the aerosol generation activity, any blower(s) (180), any means to heat the liquid (30), any means to cool the liquid (30), or any fluid pumps (130). The PLC (315) can also cause the apparatus (215) to shut down and enter a fault or error mode if the apparatus (215) is not functioning or operating within acceptable parameters. These can include, without limitation, the apparatus (215) shutting down all components and displaying a fault or error message on the HMI (320) communicating the source of the fault or error. Faults or errors can result from sources or situations including, but not limited to, insufficient liquid (30) availability to start or complete a cycle, failure to heat the liquid (30) to effective temperatures, overheating of the liquid (30) or components, failure of one or more components evidenced by the lack of current detected by a current sensor, under filling or over filling of the tank(s) (280) or reservoir(s) (40), failure of any drive electronics (645), failure of a transceiver(s) (340). If the apparatus (215) is not functioning or operating within acceptable operational parameters, the PLC (315) can also cause the apparatus (215) to emit an audible as well as visual warning. Without limitation, an audible as well as visual signal can also be communicated to the operator after the apparatus (215) has successfully completed administering the aerosol. The HMI (320) can be located inside, outside, or partially inside and outside of the apparatus (215).

[0256] At the end of the operational cycle, or upon a premature shut down of the apparatus (215) due to a failure of the apparatus (215) to function or operate within acceptable operational parameters, the apparatus (215) can create a record or report that can include, but is not limited to, whether or not there were any faults or errors during operation, the source of any faults or errors if they transpired, the lowest and highest recorded liquid (30) temperature that is in the reservoir(s) (40), the total time the aerosol was administered, the date and time the cycle was started, the date and time the cycle was completed, the room number or name if applicable, operator descriptor. The record or report may be stored, without limitation, in the memory of the PLC (315) or HMI (320), or on removable memory media, or other means known to those skilled in the art. The record or data may also be made available for printing or download via a USB port or other means known to those skilled in the art.

[0257] The PLC (315) can, without limitation, operate, energize, shut down, suspend, idle, or deactivate, one or more parts or components including, but not limited to any, (a) heater(s), (b) pump(s), (c) transceiver(s), (d) blower(s), (e) valve(s), (f) HMI(s), or (g) drive electronics, numerous times of various duration during the operation of the apparatus (215). This is particularly useful in situations that include, but are not limited to: (a) an insufficient amount of power is available to the apparatus(s) (215) to operate one or more of its parts or components simultaneously, necessitating that one or more parts and components such as, but not limited to, the blower(s) (180) and/or drive electronics (645) are temporarily idled, shut down, turned off, or suspended, to provide or make sufficient power available to the heater(s) (150) or (310), or other parts and components, (b) an insufficient amount of power is available to the apparatus(s) (215) to operate one or more of its parts or components simultaneously, necessitating that one or more parts and components such as, but not limited to, the heater(s) (150) or (310) is temporarily idled, shut down, turned off, or suspended, to provide or make sufficient power available to the drive electronics (645), or other parts or components.

[0258] The apparatus (215) can be designed, without limitation, so that all of the components or parts are mounted inside the skin or covering of the machine. For applications where the apparatus (215) is operated from within the area in which the aerosol is deployed or administered, the components or parts can be housed inside a suitable and effective NEMA or IP rated enclosure (345) that can keep any liquid, aerosol, or humidity from reaching or contacting any parts or components, and is accomplished in a manner known to those skilled in the art. The components can be independently or collectively housed in the aforementioned enclosure(s). The exterior or outside walls (755) (the term “wall(s)” can also refer to ceilings and floors in the present invention) of the apparatus (215) can, without limitation, form the NEMA or IP rated enclosure.

[0259] The apparatus (215) can, without limitation, be designed so that it can be mobile and easy to move. Without being limited, the apparatus (215) can have features including, but not limited to, a robust frame, robust wheels, bumpers, multiple grab and hoist points, and other design features known to those skilled in the art for designing a mobile apparatus (215) that can be of variable weight and size. The apparatus (215) may be constructed from any material that is compatible, and suitable for use with the liquid (30).

[0260] Without limitation, the administered or applied aerosol (200) can be removed from the area(s) in which it is applied during or after the application of the aerosol and can be accomplished with various means know to those skilled in the art. It is preferred, without limitation, that one or more ventilation or exhaust blower(s) (350) be used to pull or push air or gas and aerosol (200) out of the area(s) (210) in which the aerosol is administered or deployed. The said ventilation or exhaust blower(s) (350) can be controlled with one or more PLC(s) either not connected or connected directly or indirectly to the PLC(s) (315) of the apparatus of the present invention. The ventilation or exhaust blower(s) (350) can move any quantity of air/gas at any speed, but should have effective attributes and design for the intended application, all which is known by those skilled in the art. Anything that is removed from the area(s) (210) with the ventilation or exhaust blower(s) (350) can be done so in a manner known to those skilled in the art.

[0261] The ventilation or exhaust blower(s) (350) can also be used to bring fresh air into the area(s) in which the aerosol is applied either during or after the administration or deployment of the aerosol. The air or gas that is either removed or brought into the process area(s) can be accomplished in a manner known to those skilled in the art. The blower(s) (350) and related parts may be constructed from any material that is compatible, and suitable for use with the liquid (30).

[0262] The liquid (30) in any tank(s) or reservoir(s) (40) can be removed from the apparatus via one or more drain (655) in a manner known in the art. The movement of any liquid (30) out of the apparatus (215) can be controlled with one or more valve(s) (660). It is preferred, without limitation, that the valve(s) (660) is a solenoid valve and can communicate or send signal to one or more PLC(s) (315).

[0263] According to an embodiment, the apparatus is designed and constructed so that the aerosol producing transducer(s) (10) and/or their liquid facing surfaces or the surfaces from which there is aerosol-producing output, are able to match the angle of or remain level or parallel with, the surface of the liquid (30) above them. This is made possible by means including, but not limited to, a float assembly that holds, houses, or otherwise positions the transducers, and a gimbaled or articulating arm or holding assembly, as best shown in FIGS. 16-32. This embodiment is important for reasons including, but not limited to, the need to cover the transducers (10) with an effective amount or depth of liquid (30) to prevent the transducers (10) from being damaged due to being covered with an insufficient amount or depth of liquid (30), or to prevent the transducers (10) from being damaged by being operated without liquid above them. (30). This embodiment permits the present invention to be operated on or interfaced with surfaces that are without limitation, flat, semi-angled, angled, sloped, not sloped, or have various orientations. This embodiment does not claim, or attempt to claim, leveling the apparatus (215) by utilizing height adjustable legs or wheels that extend from the apparatus (215) and interface with a floor(s), a table top(s), or other surface(s) on which the apparatus (215) is placed or otherwise resting on, since this feature is taught in (col. 8, line 42-51) by U.S. Pat. No. 5,878,355 (Berg et al. 1996), and in (col. 8, line 50-58) by U.S. Pat. No. 6,102,992 (Berg et al. 1998). This embodiment includes interfacing, connecting, positioning, placing, or mounting, the transducers (10) to a means, or a material or object that is connected to a means, that can enable the transducer(s) (10) and/or their liquid facing surfaces or the surfaces from which there is aerosol-producing output, to match the angle of or remain aligned, level, or parallel with, the surface of the liquid (30) above them.

[0264] The first aspect of this embodiment includes, without limitation, mounting, interfacing, or connecting the aerosol generating transducers (10) to a reservoir (40) or into a reservoir (40), or to a means such as, but not limited to, one or more float(s) or float assembly(s) positioned or located in a reservoir (40), and the transducers (10) or reservoir(s) (40) is interfaced, connected, positioned, placed, or mounted, to a means (355), or a material or object that is connected to a means, that can enable the transducer(s) (10) and/or their liquid (30) facing surfaces or the surfaces from which there is aerosol (200) producing output, to match the angle of or remain aligned, level, or parallel with, the surface of the liquid (30) above them. The said means can include, but is not limited to, a ball joint, gimbal, or other means known to those skilled in the art. The components are designed and assembled in a manner known to those skilled in the art, but at least, without limitation, addresses design and assembly issues such that design considerations or variables like center of gravity and balance of the total system are sufficiently addressed and results in an effective apparatus (215). The transducers (10) in this first aspect can be, without limitation, mounted or interfaced with the reservoir(s) (40) through openings in the reservoir(s) in a way that is known to those skilled in the art, or they can be mounted, interfaced, or connected to the reservoir(s) either inside or outside of the reservoir. Without limitation, the reservoir(s) (40) can be fixed in position, free floated, or allowed to freely move. Without limitation, the reservoir(s) (40) can be enclosed, not enclosed, or semi-enclosed, so that air/gas can flow through it and carry the generated aerosol (200) away from the apparatus (215). The said means can also include, but is not limited to, hanging or suspending the entire nebulizing apparatus(s), or at least one or more of the reservoirs (40) in which the aerosol (200) is generated, from any means that would allow them to be freely hung or suspended in air or in a liquid, and have an effective free range of motion so that the transducer(s) (10) are covered with a sufficient or effective amount of liquid (30). It is preferred, without limitation, that if more than one transducer (10) is utilized, they are not only effectively covered with liquid, but that they are covered with an equal depth or amount of liquid (30). This may, without limitation, include suspending or hanging the entire nebulizing apparatus(s) or one or more of the reservoir(s) (40) in which the aerosol (200) is generated, from one or more of any pivot point, swivel, ball joint, gimbal, or other means known to those skilled in the art (1200), as shown in FIG. 51. The one or more attachment points that enable the entire nebulizing apparatus(s), reservoir(s), or chambers to be suspended or hung, are effectively positioned. The means to hang (1200) the reservoir(s) (40) or chambers may also, without limitation, attach to one or more of any pivot point, swivel, ball joint, gimbal, or other similar means known to those skilled in the art (1225), that may also be effectively connected or otherwise directly or indirectly attached to the entire nebulizing apparatus(s), or reservoir(s) (40). The nebulizing apparatus(s), reservoir(s) (40), or any related parts or components in the present invention may be attached to any material or components including, but not limited to, wiring, tubing, piping, or conduits, and they may be, without limitation, flexible. They may also, without limitation, have sufficient flexibility to enable the entire nebulizing apparatus(s) or reservoir(s) (40) to freely hang, suspend, or have an effective free range of motion.

[0265] The second aspect of this embodiment includes, without limitation, placing one or more reservoir(s) (herein referred to as “secondary reservoir(s)”) (360) inside of another reservoir(s) (herein referred to as “primary reservoir(s)”) (40). Transducer(s) (10) are mounted or interfaced to or with the secondary reservoir(s) (360) in a way that is effective and is known in the art, or they can be mounted, interfaced, or connected to the secondary reservoir(s) (360) either inside or outside of that reservoir(s) (360), in a way that is effective and known to those skilled in the art. The secondary reservoir(s) (360) may also be interfaced, connected, positioned, placed, or mounted, to a means (355), or a material or object that is connected to a means, that can enable the transducer(s) (10) and/or their liquid facing surfaces or the surfaces from which there is aerosol (200) producing output, to match the angle of or remain aligned, level, or parallel with, the surface of the liquid (30) above them. The said means can include, but is not limited to a spherical ball joint or gimbal. Without limitation, the secondary reservoir(s) (40) can be free floated or allowed to freely move. Again, the components are designed and assembled in a manner known to those skilled in the art, but at least, without limitation, addresses design and assembly issues such that the center of gravity and balance of the total system are effectively or sufficiently accommodated.

[0266] Liquid (30) from the primary reservoir(s) (40) may be pumped into the secondary reservoir(s) (360) in various ways and fill the secondary reservoir(s) (360) so that it an effective depth or amount of liquid (30) is maintained. The walls (365) of the secondary reservoir(s) (360) can be of various heights, including, but not limited to, a height that allows the liquid (30) in the secondary reservoir(s) (360) to attain at least an effective depth. More specifically, the effective liquid (30) depth in the secondary reservoir(s) (360) may be attained by means including, but not limited to, positioning one or more openings or notches in the walls (365) of the secondary reservoir(s) (360) so that a sufficient amount of liquid (30) is able to drain out into the primary reservoir(s) (40) to maintain an effective depth of liquid in the secondary reservoir(s) (360). However, it is preferred, without limitation, that the walls (365) of the secondary reservoir(s) (360) are of a height so that the liquid (30) crests and spills over the walls (365) and back into the primary reservoir(s) (40), to ensure that an effective depth of liquid (30) is maintained. The height of the walls (365) of the secondary reservoir(s) (360) can also be adjusted to compensate for any drain holes that may be present to ensure that the secondary reservoir(s) (360) may effectively drain into the primary reservoir(s) (40) once the apparatus (215) has shut down.

[0267] Without limitation, the secondary reservoir(s) (360) can be designed so that a hermitically sealed area or compartment(s) (370) with a sufficient airspace known to those skilled in the art, can connect to or is extended from at least the floor or bottom of the secondary reservoir(s) (360), or even its walls (365), to facilitate the mounting or interface of the transducers (10) and provide an environment where the transducers (10) can safely and effectively operate. Without limitation, the hermitically sealed compartment(s) (370) can extend with flexible wall material and interface with the floor, bottom, or wall(s), of the primary reservoir(s) (40), or even extend through the floor, bottom, or wall(s), of the primary reservoir(s) (40). The flexible wall material is sufficiently flexible to allow the secondary reservoir(s) (360) to effectively move. However, it is preferred without limitation that flexible tubing (375) connect the aforementioned hermitically sealed compartment(s) (370) with any airspace in which the drive electronics (645) or amplifier(s) (230) is located. Wiring from the drive electronics (645) or amplifier(s) (230) can travel through this tubing to the transducer(s) (10). The secondary reservoir(s) (360) and related components, hermitically sealed area(s) or compartment(s) (370), flexible wall material, and tubing, are constructed from any material that is compatible, and suitable for use with the liquid (30). The secondary reservoir(s) (360) can also have sensor(s) to determine if the liquid (30) is either above or below what is desired or needed. In addition, any reference made in the present invention, to any reservoir(s) (40) in which the transducer(s) (10) are located, can also apply to the reservoir(s) (360) and (40) referenced in this second aspect of the embodiment.

[0268] The third aspect of this embodiment is preferred, and it includes, without limitation, locating or suspending one or more transducer(s) (10), their wiring, and housing(s) (20), where the housing (20) can be shared or used independently with the one or more transducer(s) (10), with the transducer(s) (10) being independently, interchangeably or collectively mounted to the housing (20), and other associated circuitry, parts and components, (herein referred to as “transducer assembly(s)”) (100), at an effective orientation, depth, or distance below the surface of the liquid (30) in the reservoir(s) (40) during their operation. The transducer(s) (10) are a part of the transducer assembly(s) (100) and the transducer assembly(s) (100) may consist of one or more transducers (10). The transducer assembly(s) (100) consists of one or more transducer(s) (10) and their related parts, which are hermitically sealed in a housing (100). One or more transducers (10) and its associated parts may be located in or with a housing (20). There are numerous ways to effectively locate, position, or suspend the transducer assembly(s) (100) in the liquid (30) and includes, but is not limited to locating or suspending the transducer assembly(s) (100) at an effective distance, range, or depth, below the surface of the liquid (30), from one or more, wire(s), cable(s), tube(s), conduit(s), beam(s), or other means, that interfaces with or is attached to various locations, including, but not limited to, the walls or roof of the reservoir(s) (40), or secondary reservoir(s) (360) if it is used, or the walls or roof of the targeted area or sterilization chamber (210). The wire(s) (385) that connects from the transducer(s) (10) or transducer assembly(s) (100) to any drive electronics (645) or amplifier(s) (230) that sends signal to or operates the transducer(s) (10), can be, without limitation, protected from the liquid (30) or aerosol (200) in various ways including, but not limited to, placing, positioning, or running the wire(s) (385) inside or through tubing, pipes, conduit, beams, or other means to contain or embed the wire(s) (375) (herein referred to as “tubing”), and keep the wire(s) (385) separated from any aerosol (200) or any liquid (30). The tubing (375) may be constructed from any material that is compatible and suitable for use with the liquid (30). The wire(s) (385) may also be constructed from any material that is compatible, and suitable for use with the liquid (30). It is even more preferred that flexible tubing (375) connect the hermitically sealed transducer assembly(s) (100) with any airspace, that is hermitically or not hermitically sealed, in which the drive electronics (645) or amplifier(s) (230) is located. The flexible tubing (375) can also, without limitation, connect the environments of the transducer assembly(s) (100) and the drive electronics (645) or amplifier(s) (230) in a manner that is effective and safe, and known to those skilled in the art.

[0269] It is also preferred, without limitation, that the said tubing (375) or wire(s) (385) can connect with a suitable, effective, and usable, interface at various locations underneath the transducer assembly(s) (100). The wire(s) (385) and tubing (375) can also connect at other locations of the transducer assembly(s) (100) and in various ways known to those skilled in the art. It is further preferred that the wire(s) (385) or tubing (375) connects or interfaces with the underside of the transducer assembly(s) (100) with a watertight seal in a manner known to those skilled in the art. The wire(s) (385) or tubing (375) and wire(s) (385) can then travel through the wall(s) of the transducers assembly(s) (100) into its interior and connect to the transducer(s) (10). Without limitation, any clamp (390) made of a material that is compatible with the liquid (30), can help to create an effective seal between the tubing (375), and the housing (20) or transducer assembly(s) (100). It is even further preferred, without limitation, that the interface of the wire(s) (385) or tubing (375) with the transducer assembly(s) (100) is effectively or hermitically sealed from at least the inside of the transducer assembly(s) (100) with a means that includes, but is not limited to any, caulk, glue, sealant, or other means known to those skilled in the art, that is compatible and suitable for use with the liquid (30).

[0270] It is also preferred, without limitation, that the transducer(s) (10) or transducer assembly(s) (100), is located or suspended at an effective distance, range, or depth, below the surface of the liquid (30) by being directly or indirectly attached to or suspended from, without limitation, one or more buoyant object(s) (400), an interconnection or system of buoyant object(s) (400), or one or more components or parts that are connected or interconnected to one or more buoyant object(s) (400), where the said buoyant object(s) (400): (a) has buoyancy or neutral buoyancy but is completely submerged in the liquid (30), (b) has the ability to float partially submerged in the liquid (30), or (c) have the ability to float on the surface of the liquid (30). Without limitation, the transducer assembly(s) (100) can also be designed so that it can independently, have buoyancy or neutral buoyancy but is completely submerged in the liquid (30), have the ability to float partially submerged in the liquid (30), or have the ability to float on the surface of the liquid (30).

[0271] The transducer assembly(s) (100) and the said buoyant object(s) (400) can be designed to rise and fall in the reservoir(s) (40) to match any fluctuations in the depth of the liquid (30) in the reservoir(s) (40) so that an effective orientation and effective depth or distance below the surface of the liquid (30) in the reservoir(s) (40) is constantly maintained during the operation of the transducer(s) (10). It is also preferred, without limitation, that the transducer assembly(s) (100), as well as buoyant object(s) (400) if they are used, in the preferred aspect, be maintained in the proper, designated, or desired position(s), in an X-Y-Z coordinate plane or desired area(s) in the reservoir(s) (40), especially if the liquid (30) level fluctuates. This can be accomplished, without limitation, by connecting the transducer assembly(s) (100) or buoyant object(s) (400) with one or more control arm(s) (440) or other means, which is directly or indirectly connected to or interfaced with the walls, floors, roof, or any surfaces, of the reservoir(s) (40). The control arm(s) (440) or other means can, without limitation, be connected to any buoyant object (400). It is further preferred, without limitation that the control arm(s) (440) be designed in a manner known to those skilled in the art, so it can pivot or move in various directions or orientations. The control arm(s) (440) can also, without limitation, have one or more additional means to allow the transducer assembly(s) to freely pivot or move in various directions or orientations, and without limitation, directly or indirectly interface with the transducer assembly(s) (100). The control arm(s) (440) can be designed to keep the transducer assembly(s) (100) from inadvertently contacting any walls or surfaces of the reservoir(s) (40). The various components and parts that interface with the transducer housing(s) (20), or assist in holding or positioning the transducer housing(s) (20), are constructed from any material that is compatible and suitable for use with the liquid (30).

[0272] The control arm(s) (405) or other similar means, can also, without limitation, incorporate sensors into their design or the design of direct or indirectly connected parts and components, or in the design of the walls or ceiling of the reservoir(s) (40) so that the apparatus (215) will shut down or enter a fault or error mode if the control arm(s) (405) or related parts or components rises beyond a predetermined point due to a rise in the depth of the liquid (30) in the reservoir(s) (40), or drops below a predetermined point due to a drop in the depth of the liquid (30) in the reservoir. The type of sensors and their incorporation into the design of the apparatus (215), as well as their communication with the PLC (315) can vary. The various components utilized in this embodiment can be, without limitation, designed and assembled to address issues such as center of gravity and balance of the total system.

[0273] It is more preferred, without limitation, that one or more transducer assembly(s) (100) are effectively positioned within the reservoir(s) (40) using a combination of one or more, but not limited to, the following features or attributes: First, the transducer housing(s) (20) is located between or connected to one or more buoyant object(s) (400) of various size, shape, material, and buoyancy. Second, one or more spring clip(s) (415) are attached or connected to each buoyant object(s) (400) and interface, hold, or support the transducer housing(s) (20). Other means may also be used to connect or interface the transducer housing(s) (20) with the buoyant object(s) (400). The spring clip(s) (415) can interface with the transducer housing(s) (20) in various ways. It is preferred, without limitation, that one or more protrusions (410) from the transducer housing(s) (20) engage one or more trough(s), hole(s), or grove(s) of any shape and size present in the spring clip(s) (415).

The pin (490) can have a locking mechanism (495). Twelfth, the interface of the fixed clevis (435), rotating clevis (430), and pin (490), enable the transducer housing(s) (20) to have a free range of motion about the longitudinal axis of the pin (490).

[0275] Thirteenth, the control arm (440) has a hole (480) into or through which a torque tube (465) is positioned or connected.

Eighteenth, it is preferred, without limitation, that the torque tube (465) and bearing (475) are interfaced by inserting the torque tube (465) through a pivot hole (625) in the wall of the reservoir(s) (40), from the interior side of the reservoir(s) (40), and inserting the bearing (475) into the same hole (625) from outside of the reservoir(s) (40). Nineteenth, it is further preferred, without limitation, that the flange plate (470) interfaces with the bearing (475) outside of the reservoir(s) (40). Twentieth, the retaining spring plate (485) interfaces with the bearing (475). Twenty-first, the bearing (475) can also, without limitation, be connected or attached to the control arm (440), and the torque tube (465) and bearing (475) can be interfaced by inserting the bearing (475) and related components, through a hole (625) in the wall of the reservoir(s) (40), from the interior side of the reservoir(s) (40), and inserting the torque tube (465) and related components, into the same hole (480) from outside of the reservoir(s) (40). In this situation, the flange plate (470) would interface with the bearing (475) inside of the reservoir(s) (40).

The control arm(s) may have any range, angle, or degree of motion or movement. It is preferred, without limitation, that the control arm(s) (440) can have up to thirteen degrees in vertical, arc, or semi-vertical motion. Twenty-third, in essence, the control arm(s) (440) is connected to a torsional tube (445) that transfers motion from the inside of the reservoir(s) (40) through the reservoir(s) (40) walls, to the switch actuator plate (565).

[0277] Twenty-fourth, one or more switch actuator plates (565) is interfaced with the torsional tube (445) or bearing (475) and is located at the exterior of the reservoir(s) (40). It is preferred, without limitation, that the switch actuator plate(s) (565) is interfaced with the torsional tube (445). Twenty-fifth, the movement of the control arm(s) (440) directly or indirectly causes the switch actuator plate(s) (565) to move. Twenty-sixth, the switch actuator plate(s) (565) is designed so that its movement causes the actuation of one or more various switch(s) (590). The switch actuator plate(s) (565) can be of many different shapes, sizes, and geometries. Twenty-seventh, any type and number of switch(s) (590) may be used to indicate or communicate any condition(s) or situation (s) in the reservoir(s) (40). Twenty-eighth, the switch(s) (590) may be located anywhere around, in front of, or at any effective proximity to the switch actuator plate(s) (565). It is preferred, without limitation, that the switch actuator plate(s) (565) has one or more protrusion(s), groove(s), or indentation(s) (665), which can interface with and contact or actuate one or more switch(s) (590). Twenty-ninth, one or more switch(s) (590) are interfaced with or connected to one or more base plate(s) (540) which is interfaced with the exterior wall(s) of the reservoir(s) (40) or other surfaces. Thirtieth, the position and meaning of each switch (590) connected to a base plate(s) (540) can vary and be interchanged. It is preferred, without limitation, that three switches (590) are used to indicate or communicate to the PLC(s) (315) the various liquid levels in the reservoir(s) (40). The first switch is the tank full switch (550). Without limitation, the interaction or lack of interaction of the switch actuator plate(s) (565) with this switch (550) can indicate or communicate to the PLC(s) (315) that the liquid (30) level in the reservoir(s) (40) is at or above a designated or specified level. This can, without limitation, cause one or more valves (300) that control the flow of liquid (30) into the reservoir(s) (40) to close. The second switch is the tank refill switch (555). Without limitation, the interaction or lack of interaction of the switch actuator plate(s) (565) with this switch (555) can indicate or communicate to the PLC(s) (315) that the liquid (30) level in the reservoir(s) (40) is at or below a designated or specified level and the reservoir(s) (40) needs refilling. This can, without limitation, cause one or more valves (300) that control the flow of liquid (30) into the reservoir(s) (40) to open or semi-open. The third switch is the tank low level switch (560). Without limitation, the interaction or lack of interaction of the switch actuator plate(s) (565) with this switch (560) can indicate or communicate to the PLC(s) (315) that the liquid (30) level in the reservoir(s) (40) is at or below a designated or specified level. This can, without limitation, cause various components of the apparatus (215) to shut down such as, but not limited to any, pump(s) (130), blower(s) (180), heater(s) (150) or (310), or any drive electronics (645) or amplifier(s) (230).

[0278] Thirty-first, one or more cover plate(s) (580) fit over the switch(s) (590). The cover plate(s) can, without limitation, provide rigidity to the various connected components (610) and prevent damage to the switches (590) resulting from possible contact with any objects. The cover plate(s) (580) can also prevent certain shock hazards as well as act as a passive terminal protection for the various switch(s) (590).

[0279] Thirty-second, one or more hydraulic dampener(s) are connected to the switch actuator plate(s) (565) or any other components that directly or indirectly connect to the transducer assembly(s) (100), buoyant objects (400), or control/control arm (440). The hydraulic dampener(s) (585) is a push or pull hydraulic mechanism whose design and function is known in the art. The hydraulic dampener(s) (585) can, without limitation, dampen any rotation or movement of the control arm (440), transducer housing(s) (20), switch actuator plate (565), or other related components, resulting from any shock and vibration that the apparatus (215) may encounter.

[0280] It is further preferred, without limitation, that an enhanced design for interfacing one or more transducer(s) (10) with one or more housing(s) (20) in various and modifiable configurations is utilized in the present invention. This design includes, without limitation, the following features. First, each housing (20) that is utilized is constructed so that it has one or more space(s) or recess(s) (600) that interface with one or more transducer(s) (10) as desired. The housing(s) may be made of any suitable material that is not affected by the chemical action of the liquid (30). Suitable materials for the housing(s) (20) may include PVC, polypropylene, and stainless steel, but other suitable materials may be used. It is preferred without limitation that the housing(s) (20) is made from stainless steel. It is preferred, without limitation, that three spaces or recesses (600) are utilized per transducer housing (20), and the center space or recess (620) connects with the other spaces or recesses (600) through one or more hole(s), opening(s), pipe(s), channel(s), or conduit(s) (herein referred to as “holes”) (535). The wire(s) (385) that connect the amplifier(s) (230) to the transducer(s) (10), enter the housing(s) (20) through one or more hole(s), opening(s), pipe(s), channel(s), or conduit(s) (605) located anywhere on the side of the housing (20) that faces opposite from the surface of the liquid (30) in the reservoir(s) (40). The wire(s) (385) can, without limitation, enter the center space(s) or recess(s) (620) and travel through the hole(s) (535) to connect with their respective transducer(s) (10). The wire(s) (385) connect with the transducer(s) in a manner known to those skilled in the art.

[0281] Each space(s) or recess(s) (600) or their surrounding surfaces (640) can interface with one or more o-rings (635). It is preferred, without limitation, that each space(s) or recess(s) (600) interfaces directly or indirectly with at least three different o-rings and various other parts or components. The first o-ring is the secondary o-ring (515), and it interfaces with a concentric shelf (630) that is built into each space or recess (600). The second o-ring is the outside o-ring (510), and it interfaces with the outside circumference of the compression ring (525). Without limitation, any surface of each housing (20) can have groves or indentations of various construction in which the o-rings can be seated, and the groves are designed and constructed in a manner known to those skilled in the art. The transducer (10) is interfaced or adhered to the barrier (60). It is preferred, without limitation, that the barrier (60) is constructed from glass. The barrier (60) is interfaced with, seated into, or nested on top of the secondary o-ring (515). The third o-ring is the primary o-ring (520), and it interfaces with the liquid (30) facing side of the barrier (60) and any of the inside surfaces (525) of the compression ring (525). The compression ring (525) can be constructed from any suitable material that is not affected by the chemical action of the liquid (30). Suitable materials of the compression ring (525) may include PVC, polypropylene, and stainless steel, but other suitable materials may be used. It is preferred, without limitation that the compression ring (525) is made from stainless steel. Any o-rings, including the secondary o-ring (515), outside o-ring (510), and primary o-ring (520), can have any cross section shape, or hardness, and are constructed from any suitable material that is not affected by the chemical action of the liquid (30). It is preferred, without limitation, that the primary o-ring (520) and secondary o-ring (515) have a double seal cross-section shape, and the outside o-ring (510) has a round cross-section shape, and these various o-rings are constructed from Viton material. The various components, except for the transducer (10) and barrier (60) are assembled and compressed together to form a watertight seal in various ways known to those skilled in the art. Without limitation, tub walls (530) may also interface with any housing(s) (20).

[0282] The control arm(s) (405), transducer assembly(s) (100), reservoir(s) (40), and other related component(s), can be designed, so that when the reservoir(s) (40) is drained, the buoyant object(s) (400), transducer assembly(s) (100), control arm(s) (405), or other connected parts or components will move down into or onto, one or more of any means to sufficiently and effectively prop, position, stabilize, or hold, the buoyant object(s) (400), transducer assembly(s) (100), control arm(s) (405), or other connected parts or components, at any angle or orientation, within the reservoir(s) (40). This may include, without limitation, any mechanism(s), apparatus(s), structure(s), inset mold(s), nest(s), groove(s), indentation(s), or protrusion(s) (herein referred to as “structure”) (1050) that can, interface with the buoyant object(s) (400), transducer assembly(s) (100), control arm(s) (405), or other connected parts or components, or without limitation, partially, generally, roughly, or exactly, mirror or generally mirror, at least a sufficient amount of the contours or geometry of the buoyant object(s) (400), transducer assembly(s) (100), control arm(s) (405), or other connected parts or components, to be effective. The said mold(s), inset(s), nest(s), groove(s), indentation(s), or other structures can be designed to drain if necessary or when desired, in a manner known to those skilled in the art. When the reservoir(s) (40) is drained the buoyant object(s) (400), transducer assembly(s) (100), control arm(s) (405), or other connected parts or components, can rest, without limitation, at any angle or orientation to provide an angle that is steep enough for any deposited liquid to move off or drain from any surfaces of the transducer assembly(s) (100), including any surfaces above or interfaced with the transducers(s) (10), into the reservoir(s)'s (40) drain(s) (655).

[0283] According to an embodiment, the protective barrier (60) that interfaces with the transducer(s) (10) can be polished on one or more sides. When a protective barrier (60) is ground to a specific thickness, its ground sides may have an appearance or characteristics that can include, but is not limited to, unpolished, rough, hazy, or frosted due to the grinding process. This is, without limitation, especially true with protective barriers (60) that are constructed from any type of glass that is ground. The prior art has taught the use of protective barriers (60), including glass, in U.S. Pat. No. 3,433,461 (Scarpa et al.), U.S. Pat. No. 3,729,138 (Tysk), U.S. Pat. No. 4,109,863 (Olson et al.), and U.S. Pat. No. 4,976,259 (Higson et al.), which are incorporated herein by reference in their entirety, including any references cited therein. However, the prior art is silent with respect to the use of a polished barrier(s). It can be assumed that the protective barriers (60) mentioned in the prior art were ground to their specific thicknesses but not polished after being ground. Polishing the liquid side of the protective barrier (60) can, without limitation: (a) reduce or eliminate the texture or surface features that can catch or hold undesirable foreign objects or debris, (b) provide a surface that easier to clean and/or be more effectively cleaned, (c) reduce the amount of texture or surface features that may promote the build up of mineral deposits, (d) promote easier movement of liquid (30), foreign objects, or debris, off of the protective barrier (60) surface(s) when the reservoir(s) (40) is emptied. Polishing the side of the protective barrier (60) that is not in contact with the liquid can, without limitation: (a) reduce surface variability on the side of the protective barrier (60) that interfaces with any adhesive (70), which can reduce the variability in the thickness of the adhesive (70) between the protective barrier (60) and transducer(s) (10) which may in turn, without being limited, reduce variability in certain energy transmission characteristics or other transmission related issues. An unpolished protective barrier (60) surface that interfaces with an adhesive (70) can enhance the bonding between the protective barrier (60) and the transducer(s) (10) for reasons known to those skilled in the art. The protective barrier (60) in the present invention can, without limitation, be polished or unpolished on both the liquid (30) and transducer (10) facing sides. However, it is preferred, without limitation, that the protective barrier (60) is polished on the side that faces the liquid (30) and remain unpolished on the side that faces the transducer(s) (10). Polishing in this embodiment can vary in ways including, but not limited to its, depth, completeness, precision, quality, and accuracy.

[0284] According to an embodiment, the apparatus can be designed and constructed so that more than one aerosol producing transducer (10) is surrounded, enclosed, or encircled by one or more walls or barriers (herein referred to as “tub walls”) (530). However, if only one transducer (10) is used in the present invention, it may also be surrounded, enclosed, or encircled by one or more tub walls (530). This embodiment should not be confused with what is taught in U.S. Pat. No. 5,300,260 (Keshet et al., 1993) in (col. 3, line 15-21) and (col. 3, line 50-51), which is incorporated herein by reference in its entirety, including any references cited therein. Keshet et al., taught the positioning of baffles between each aerosol producing transducer as a means to suppress waves. The tub walls (530) in this embodiment are not positioned between individual transducers (10) so as to not conflict with U.S. Pat. No. 5,300,260. The performance of the transducers (10) in the present invention was found in the laboratory not to be adversely effected by waves created by neighboring, or even closely positioned transducers (10). The art taught by Keshet et al. is inapplicable to the present invention. The walls (10) in the present invention are intended to contain the liquid (30) above and around the transducers (10) and use the heat generated by the transducer(s) (10) to heat the liquid (30) above and around the transducer(s) (10), as well as the liquid (30) at the liquid (30) surface above the transducers (10). This embodiment may, without limitation, eliminate the need for any additional means to heat the liquid in certain circumstances known to those skilled in the art. This embodiment utilizes teachings from the book titled, “Aerosol Technology” by William C. Hinds (1982), which is incorporated herein by reference in its entirety, including any references cited therein, where it is taught that ultrasonic aerosol generating transducers can heat the surrounding liquid (page 382). This embodiment can without limitation, offer the added benefit of enabling the transducers (10) to quickly heat the surrounding liquid (30) and liquid (30) surface above them. The tub walls (530) can also, without limitation, be designed or modified in a manner known to those skilled in the art so that the liquid (30) contained within the tub walls (530) is able to reach or experience an effective exchange with the surrounding liquid (30) outside of the tub walls (530), so that the liquid (30) within the tub walls (530) is not able to either exceed a given temperature or drop below a given temperature. Without limitation, the tub walls (530) can be continuous or non-continuous, and they can have one or more openings (670) of various size, shape, and in various locations. The tub walls (530) can, without limitation, be sealed or partially sealed, interfaced or not interfaced, interlocked either tightly or loosely, or be unsealed. The tub walls (530) can without limitation, interface completely or intermittently, or not interface, with the surfaces of the transducer assembly(s) (100) or the housing (20), and the height of the tub walls (530) can also vary. Any gap or distance (925) may exist between the tub walls (530) and any surfaces of the transducer assembly(s) (100) or the housing (20). It is preferred without limitation, that the tub walls (530) extend to an effective height above the surface of the liquid (30). Without being limited, one or more notches can also be cut into the top of the walls and can be of various size, shape, and in various locations. The tub walls (530) and associated parts may be constructed from any material that is compatible, and suitable for use with the liquid (30). The tub wall(s) (530) can also be designed and constructed to perform the same function(s) as the buoyant object(s) (400), or share any of the same features of the buoyant object(s) (400). The tub wall(s) (530) can, without limitation, have any density, buoyancy, air space, thickness, size, shape, and can be injection or blow molded. Without limitation, the tub wall(s) can be directly or indirectly positioned or interfaced anywhere with and in any orientation to the transducer assembly(s) (100) or housing(s) (20). The tub wall(s) (530) can have any number of vertical or angled voids, holes or openings (herein referred to as “openings”) (920) above the transducer(s) (10) or transducer assembly(s) (100). The openings (920) can, without limitation, allow any emitted pressure (energy) resulting from the operation of the transducer(s) (10), to reach the surface of the liquid (30) in the reservoir(s) (40). The openings (920) can be any size, shape, or have any angle or cant.

[0285] According to an embodiment shown in FIGS. 53 and 36, the apparatus can be designed and constructed so that air/gas that surrounds the apparatus (215) or outside air/gas that is pulled into the apparatus (215) for purposes including, without limitation, removing the aerosol (200) that is generated by the transducer(s) (10), from the apparatus (215) and into the intended or targeted area (210), is filtered before it enters the apparatus (215), or at least before the air/gas reaches the aerosol generation chamber (40). One or more filters (675) of various kinds and function, may be used, but should be at least sufficient for the intended amount or degree of filtering that is desired or needed, and the correct filter (675) that is used for a specific application is known to those skilled in the art. It is preferred, without limitation that the filter(s) (675) is located at any location where the air/gas is drawn or pulled into the apparatus (215) by a blower or fan or other means (180) to move the air/gas or aerosol (200). It can be located either on the inside or outside of the apparatus (215) and sufficiently interfaced with the apparatus (215) in a manner that is known to those skilled in the art. The filter(s) (675) can, without limitation, prevent or limit dust or debris contamination inside of, on, or in: (a) any liquid (30), (b) any pipe(s) (685) that are used to construct the aerosol generating apparatus (215) through which the air/gas is moved, (c) the fan or blower or other source of pressurized air (180), (d) the chamber (40) in which the transducer(s) (10) are located, or (e) the introduction of various types of contaminates into the intended or targeted area (210) in which the aerosol (200) is deployed. The filter(s) (535) are not used in any configuration(s) or application(s) involving a “closed loop system” where the air/gas or aerosol (200) that is deployed from the apparatus (215) is then recirculated back to the apparatus (215) through one or more return conduit(s) or pipe(s) (240). This avoids any conflict with: (a) (col. 3, line 19-24), (col. 11, line 14-17) and (claim #21) of U.S. Pat. No. 5,878,355 (Berg et al. 1996), and (b) (col. 3 line 26-31), (col. 11, line 20-23) and (claim #8) of U.S. Pat. No. 6,102,992 (Berg et al. 1998), both of which are incorporated herein by reference in its entirety, including any references cited therein. The filter(s) (675) can be, without limitation, disposable. One or more protective covers (680) may also be directly or indirectly connected to the filters (535). The protective covers (680) may be positioned, or installed anywhere in the air/gas stream before the air/gas enters the filter(s). One or more protective cover(s) (680) may also be integrated into any external walls (755) of the apparatus and may be constructed from any material that is compatible, and suitable for use with the liquid (30).

[0286] According to an embodiment, the apparatus (215) can be designed and constructed so that one or more tank(s) (herein referred to as “intermediate tank(s)”) (695), are connected between the one or more tank(s) (280) in which liquid (30) is stored and the reservoir(s) (40) they feed or supply, in which transducer(s) (10) are located. The intermediate tank(s) (280) can, without limitation, perform the function of a check or failsafe device or design, and prevent the reservoir(s) (40) in which the transducers (10) are located from being overfilled with liquid (30) if one or more valve(s) (300) from the tank(s) (280) that feed or supplies the reservoir(s) (40) fail in an open or semi-open position. The intermediate tanks (695) can have one or more of various types of valves (300) that include, but are not limited to, float valves, or solenoid valves. The valve(s) (300) can control the flow of either inbound or outbound liquid (30). The said valve(s) (300) can, without limitation, be actuated by a PLC (315), or by one or more sensor(s) (305) located in the intermediate tank(s) (695) or reservoir(s) (40) in which the transducer(s) (10) are located, and is accomplished in a manner known in the art. The valve(s) (300) are also installed, and connected to a PLC (315), if applicable, in a manner known to those skilled in the art. The valve(s), immediate tank(s), and associated parts may be constructed from any material that is compatible, and suitable for use with the liquid (30).

[0287] According to an embodiment, the apparatus (215) can be designed and constructed so that one or more liquid containment tank(s) (705) is connected to various parts, components, or areas of the apparatus including, but not limited to, the fill pipe(s) (295), blower or fan housing(s) (180), internal catch pan(s) or basin(s) (700), reservoir(s) (40) in which the transducers (10) are located, or pressurized air pipe(s) or conduit(s) (685). Without limitation, the aforementioned liquid containment tank(s) (705) is designed to collect excess, spilled, leaked, coalesced, or other undesired liquid (30). It can be connected to the main drain (655) and valve (660) used to drain the apparatus, or it can have its own drain pipe and valve. The positioning of the liquid containment tank(s) (705) as well as its shape and capacity can vary. A liquid level sensor (305) may be used to detect the presence of any liquid (30) or the depth of the liquid (30) in the containment tank(s) (705). The said liquid level sensor (305) may communicate with a PLC (315) and cause the apparatus to shut down or enter a fault or error mode if the if the liquid level (30) exceeds a defined depth. The liquid containment tank(s) (705) and associated parts may be constructed from any material that is compatible, and suitable for use with the liquid (30). Without limitation, any pipe(s) (685) carrying inbound or outbound air or aerosol, as well as the blower(s) (180) and the pipe(s) (685) that connect it to the reservoir(s) (40) in which the transducers (10) are located, can be canted or angled back toward the reservoir(s) (40) in which the transducer(s) (10) are located to carry out various functions such as, but not limited to, helping collect any liquid (30) from those areas.

[0288] According to an embodiment, the apparatus can be designed and constructed so that it has one or more means to control the temperature of the liquid (30) in the various reservoir(s), which includes, but is not limited to, preventing the temperature of the liquid (30) in the reservoir(s) (40) in which the transducers (10) are located, from exceeding the maximum desired, established, or required operating temperature for that liquid (30) or particular process in which the liquid (30) is being used.

[0289] As previously discussed, the prior art has taught the heating of the liquid (30) in various ways including, but not limited to, heating the liquid (30) from the heat that is imparted into the liquid (30) during the operation of the transducers (10). It is obvious to one skilled in the art, that the air or gas that is used to remove the generated aerosol (200) from the reservoir(s) (40) in which the transducers (10) are located, can contribute to the removal of heat from the liquid (30). However, this pressurized air/gas flow can only remove a certain quantity of heat and is affected by factors including, but not limited to, the surface area of the liquid (30) in the reservoir(s) (40), and the volume and velocity of air/gas that moves over that surface area. If more heat is imparted into the liquid (30) than is removed over time, the liquid (30) will continue to rise in temperature.

[0290] The means to control or prevent the temperature of the liquid (30) in the reservoir(s) (40) in which the transducers (10) are located, from exceeding the aforementioned maximum desired, established, or required operating temperature, includes without limitation, a means to cool the liquid (30) by pumping or otherwise moving the liquid (30) that is in the reservoir(s) (40) in which the transducer(s) (10) are located, or any other liquid (30) that could possibly have contact with the liquid (30) in the reservoir(s) (40) in which the transducer(s) (10) are located, through a heat exchanger, cooling fins, cooling plate, cooling block, chiller, chilling or cooling apparatus, or other means known in the art (710), to remove heat from the liquid (30). It is preferred that this means includes pumping or moving the liquid (30) from the reservoir(s) (40) in which the transducers (10) are located, through cooling fins, chill block, or heat exchanger that is located in the path of the pressurized air/gas that is used to move the generated aerosol (200) away from the apparatus. The means to cool the liquid (30) can also interface or directly interface with the reservoir(s) (40) in which the transducers (10) are located and can include, but is not limited to, the interface or insertion of chill coil(s) or chill block(s) directly into the reservoir(s) (40) in which the transducers (10) are located. The means mentioned in this embodiment to cool the liquid (30) and associated parts may be constructed from any material that is compatible, and suitable for use with the liquid (30). The PLC(s) (315) can monitor the temperature of the liquid (30) in the reservoir(s) (40) with input from one or more liquid temperature sensing device(s) (820). The PLC(s) (315) can activate whatever means necessary to start, maintain, or stop any liquid (30) cooling activities or actions, to maintain any desired or necessary temperature.

[0291] An additional aspect of this embodiment includes, without limitation, insulating the reservoir(s) (40) in which the transducer(s) (10) are located, in various ways including, but not limited to, interfacing or applying any type of insulation material (760) to any surfaces of the reservoir(s) (40), or using a double wall construction (765) for the reservoir (40) where the said walls are separated with a layer of air, or other means known to those skilled in the art. Without limitation, insulating the reservoir(s) (40) can be useful in environments where it is important to increase heating efficiency or capacity and diminish heat loss from the system.

[0292] According to an embodiment illustrated in FIGS. 33 and 34, the apparatus can be designed and constructed so that it can be remotely communicated with and controlled, by anyone or any means. Without being limited, one or more PLC(s) (315) that control one or more parts of the apparatus can also communicate with or be controlled by any other apparatus and their PLC(s). More specifically, and without limitation, the remote control and communication with the apparatus can be accomplished by means such as, but not limited to, any radio frequency or amplitude, any electrical frequency or amplitude, any light frequency or amplitude, any digital or analog data packet, or by any directly or indirectly connected wire(s), which includes fiber optic wire(s), or any combination of the of the said means. Without limitation, any data, commands, or information can be sent and received by the apparatus and communicated between the apparatus and one or more additional means to send and receive any data, commands, or information. Commands, can include, but are not limited to, a command for the apparatus to start or to end an aerosol generation or deployment cycle. Communicated information or data can include, but is not limited to, the apparatus communicating its current operational status or condition, as well as liquid (30) level and temperature. It is preferred, without limitation, that the apparatus communicates by using one or more radio transceiver(s) (340) that is connected to one or more PLC(s) (315), that is connected to one or more HMI(s) (320), and communicates with one or more remote radio transceiver(s) (315) that is connected to one or more remote PLC(s) (315) which are attached to one or more remote HMI(s) (320) or other parts or components. The one or more antenna(s) (720) connected to the radio transceiver(s) (340), can be located anywhere on or in the apparatus (215), and can be constructed from various materials. The antenna(s) (720) and any related parts may be constructed from any material that is compatible, and suitable for use with the liquid (30). It is preferred, without limitation, that the radio transceiver(s) (340) and antenna(s) (720) be located within any NEMA or IP rated or hermitically sealed container(s) (345) that is constructed from polymer that is compatible, and suitable for use with the liquid (30). Within this embodiment, and without limitation, a plurality of apparatuses, including, but not limited to, apparatuses that are similar in process, or apparatuses that are similar or identical to the apparatus (215) of the present invention, can operate in the same, connected, or shared volume of space, and communicate information including, but not limited to their condition or status of their systems or the apparatus in general, to all of these apparatuses, so that if one apparatus has a problem, or enters into a fault or error condition or state, all of the other apparatuses can also shut down, or at least relay the incident to one or more remote PLC(s) (315), HMI(s) (320) which the operator can monitor. This embodiment also offers many advantages including, but not limited to, reducing or eliminating the chance of accidental exposure to the aerosol (200) from an apparatus (215) that is operating within the same environment (210) in which the aerosol (200) is applied.

[0293] According to an embodiment, the apparatus (215) can be designed and constructed so that it has one or more sensors, or the means for indirect or direct communication with one or more sensor(s) or PLC(s) (315) which are connected to one or more sensor(s), to determine if an effective or sufficient amount of aerosol (200) has been applied to the targeted area (210) and/or surfaces.

[0294] In the first aspect of this embodiment, each sensor consists of at least two parts including, but not limited to, a light source (725) and a light sensor (730), known to those skilled in the art. The light source (725) and light sensor (730) can be directly or indirectly connected, or they can be placed or positioned independent from one another. The distance between the light source (725) and light sensor (730) can vary. It is preferred without limitation, that the light source (725) and light sensor (730) are at separated by at least one foot. It is more preferred, without limitation, that the light source (725) and light sensor (730) be separated by at least four feet. It is even more preferred, without limitation, that the light source (725) and light sensor (730) be separated by at least seven feet. It is preferred, without limitation, that each sensor(s) consists of at least one laser of any power or class type for a light source (725), and at least one photoelectric sensor of any type and sensitivity (730) for a light sensor (730). The emitted light or energy, or light source (725) can have, without limitation, various: (a) intensity(s), (b) brightness, (c) period(s), (d) frequency(s), and (e) wavelength(s). The light source (725) can be controlled via a PLC (315), the light sensor(s) (730), or other means known in the art. The means to sense the light (730) can, without limitation, vary widely in its sensitivity and ability to sense light of various: (a) intensity(s), (b) brightness, (c) period(s), (d) frequency(s), and (e) wavelength(s). The means to sense the light (730) can also have various capabilities known in the art, including, without limitation, the ability to have adjustable sensitivity and trigger level(s), or the ability to communicate with a PLC(s) (315) or other components. The light sensor(s) (730) can, without limitation, indicate or communicate to a PLC(s) (315) if it either receives or ceases to receive a desired or set level of light stimulus, and the said communication can be accomplished in various ways known in the art. It is preferred, without limitation that the PLC(s) (315) is indicated or receives information by either an electrical signal or lack of an electrical signal from the light sensor(s) (730). This communication can result in various actions such as, but not limited to: (a) shutting down any drive electronics (645) or amplifier(s) (230), (b) shutting down the blower (180) or flow of pressurized air, or (c) shutting down the apparatus (215).

[0295] Without limitation, an effective or sufficient amount of administered aerosol (200) in this embodiment is indicated by its causing the disruption, diminishment, or cessation, of the light that is emitted from the light source(s) (725) before it reaches the photoelectric sensor (730). The effective, sufficient amount, or specified quantity, of administered aerosol (200) can vary for intended or unintended reasons or designs, and the trigger or sensitivity levels for the light sensor(s) (730) can, without limitation, be varied, calibrated, or adjusted, for each situational circumstance.

[0296] In the second aspect of this embodiment each sensor can sense or measure relative humidity in a manner known to those skilled in the art. Without limitation, the relative humidity sensor(s) (735) can have various capabilities and attributes including, without limitation, varying sensitivity, the ability to have adjustable trigger level(s), or the ability to communicate with a PLC(s) (315) or other components. The humidity sensor(s) (735) can, without limitation, indicate or communicate to a PLC(s) (315) the relative humidity data it collects, which can be accomplished in ways known in the art. The relative humidity sensor(s) (735) can receive or send any signal of any kind to or from any other components. It is preferred, without limitation, that the PLC(s) (315) receive humidity data or indications of various humidity detection events by either an electrical, optical, or radio signal, or lack of these signals from the relative humidity sensor(s) (735) or any components connected to the relative humidity sensor(s) (735). It is preferred, without limitation that the PLC(s) (315) is indicated by either an electrical signal or lack of an electrical signal from the relative humidity sensor(s) (735) when a certain humidity level is detected. This communication can result in various actions such as, but not limited to: (a) shutting down any drive electronics (645) or amplifier(s) (230), (b) shutting down the blower (180) or flow of pressurized air, or (c) shutting down the apparatus (215).

[0297] Also, without limitation, the PLC(s) (315) can be programmed to have delays of various length of time after receiving any data, communication, or signal, to initiate actions such as, but not limited to: (a) shutting down any drive electronics (645) or amplifier(s) (230), (b) shutting down the blower (180) or flow of pressurized air, or (c) shutting down the apparatus (215), after receiving any signal(s), data, or communication from any sensor(s) such as the light sensor (730) or the relative humidity sensor(s) (735) or related components.

[0298] According to an embodiment, the apparatus can be designed and constructed so that it can without limitation, measure, determine, or sense, the amount of liquid (30) that is in any tank or reservoir. Without limitation, this information or data may be used, in concert with or without a PLC (315), to: (a) communicate to the operator whether there is either a sufficient or insufficient amount of liquid (30) to execute a chosen operational cycle time, (b) communicate to the operator whether there is either a sufficient or insufficient amount of liquid (30) to execute an operational cycle time associated with a specific volume of space or other attribute(s) chosen by the operator, (c) communicate to the operator the quantity of liquid (30) or at least the minimum quantity of liquid (30), expressed in units of measure, which may be necessary to add or make available to the apparatus so that it may effectively or successfully complete a chosen or desired operational cycle. It is preferred, without limitation, that the units of measure in the present invention include, but are not limited to, any liquid (30) volume quantities expressed in, standard units of measure, imperial units of measure, English units of measure, units of measure according to the metric system, or units of measure according to System International (SI) units. French Patent No. FR2860721 (Schwal et al.), which is incorporated herein by reference in its entirety, including any references cited therein, taught that a fogging apparatus can notify the operator if an insufficient liquid (30) quantity is available (pg. 6 line 15-25 and pg. 10 line 10-25) and when it is necessary to replace a cartridge (290) (pg. 10 line 15-25). However, FR2860721 (Schwal et al.), only mentioned that an indication would be made by the fogging apparatus to the operator to replace an interfaced cartridge (290) (pg. 10 line 15-25), or additional possibly interfaced cartridges (290) (pg. 7 line 3-10), but it was silent with respect to the apparatus itself determining the amount of liquid (30) that is needed to properly or effectively fill the apparatus, and communicating the exact number of a plurality of cartridges (290) that may be needed to fill the apparatus with liquid (30) either partially or to full capacity so that it can successfully and effectively complete a predetermined operational cycle. Therefore, it is more preferred, without limitation, that the units of measure communicated can also include more than one or a plurality of cartridges (290) with a known quantity of liquid (30) that is needed to provide the apparatus with a sufficient quantity of liquid (30) for it to effectively or successfully complete its operational cycle time. It is even more preferred, without limitation, that the units of measure include, any units of measure, including any number of cartridges (290) as long as it is a plurality of cartridges. The apparatus can, without limitation, communicate to the operator the minimum quantity of liquid (30) needed to complete an operational cycle, as well as the quantity of liquid (30) that would be needed to fill the apparatus to capacity. Again, the quantity of liquid (30) may be expressed in any units of measure including, but not limited to, the number of cartridges (290). Information or data can be communicated to or from the apparatus with any means known to those skilled in the art including, but not limited to, human-machine-interface(s) (HMI) (320), terminal(s), remote terminal(s), any button(s) and associated light(s), screen(s), or audible signal(s). The apparatus can, without limitation, require the operator to acknowledge one or more prompts to add a certain amount of liquid (30) or a certain number of cartridges (290) as well as one or more prompts to verify if the action was undertaken. This can be accomplished with an HMI (320) or other means known to those skilled in the art. More specifically, this embodiment includes without limitation, the apparatus having the ability to sense, detect, or determine, with one or more sensor(s) or other effective means, any: (a) liquid (30) level, (b) liquid (30) depth, or (c) amount of liquid (30) in any tank(s), reservoir(s) (40), or other places where liquid (30) is held and available to the apparatus, and communicate that information to a PLC(s) (315). This may be accomplished in a manner known to those skilled in the art. It is preferred, without limitation, that one or more float sensor(s) (305), which can be located in various locations in the apparatus, be utilized for this purpose. They can be constructed from any material that is compatible, and suitable for use with the liquid (30), and their use and configuration are known to those skilled in the art. Any data, information, or signals, can be sent from the said means to sense, detect, or determine the liquid (30) level, liquid (30) depth, or amount of liquid (30) available, and can be sent or communicated, without limitation, to various places or means including, but not limited to, one or more PLC(s) (315) or HMI(s) (320). The PLC(s) (315) or HMI(s) (320) can be programmed in a manner known in the art to use the inbound information, data, or communication to control or interact with the apparatus, as well as communicate information to or from the operator. The PLC(s) (315) can, without limitation, be programmed so that the apparatus (215) will enter into a fault or error condition, or shut down one or more functions, and communicate an audible or visual signal to the operator, as well as communicate with any other PLC(s) (315), if the apparatus receives a command to operate for a certain amount of time or apply aerosol (200) to a certain volume and the PLC(s) (315) determines that an insufficient amount of liquid (30) is available.

[0299] According to an embodiment, the apparatus (215) can be designed and constructed so that it will not, without limitation, generate, create, or deploy aerosol (200), when the liquid (30) that is in or available to the reservoir(s) (40) in which the transducer(s) (10) are located cannot be used, administered, or deployed, for reasons including but not limited to: (a) the fluid (30) has exceeded the time or date within which it can be efficaciously used, or (b) the fluid (30) has reached a point in time or date where it has degraded or aged to a point where its use or application would be ineffective, unaccepted, unauthorized, or illegal. The present embodiment does not encompass what is taught in French Patent No. FR2860721 (Schwal et al.), which is incorporated herein by reference in its entirety, including any references cited therein. That patent includes placing or fitting a container(s) or cartridge(s) (290) of single use that is filled with the liquid (30) to be fogged or diffused, on or with an aerosol (200) dispensing device, and reading an identifier on the said container(s) with a reader (pg. 2, line 33-36) to determine its year/date (pg. 9 line 15-20) and suspending the operation of the apparatus if there is non-conformance, or in other words, the identifier(s) is determined to be associated with a container(s) that has expired. However, this embodiment, without limitation, also encompasses the liquid (30) that is in any cartridge(s) (290) (FIG. 12) that interfaces with the apparatus after the cartridge(s) (290) has been read and its use is approved, and the cartridge(s) (290) is opened or its seal is compromised, allowing the liquid (30) to be used or made available to the apparatus. This is important for reasons including, but not limited to, the liquid (30) can have a certain shelf life or period of effectiveness while in a closed container/cartridge (290), but once the container/cartridge (290) is opened, and exposed to its surrounding environment, or diluted, the shelf life or effective period of use is diminished or shortened. This can, without limitation, necessitate the monitoring, measuring, tracking, calculating, comparing, (herein “measuring”), the time that the liquid (30) can be utilized in the present invention until it cannot be used for various reasons known to those skilled in the art. Measuring the time that the liquid (30) can or cannot be used or its useful lifespan, can be accomplished by using a PLC(s) (315), or other mechanism or device known to those skilled in the art. The apparatus (215) in this embodiment can possesses various means to determine the useful lifespan of a liquid (30) or the length of time a liquid (30) can be effectively utilized by the apparatus, and such means may include, but is not limited to, the following or combination of the following: (a) measuring the time between when an empty apparatus (215) is initially filled with liquid (30) and the time when it should be drained of the liquid (30), which is preferred in this embodiment, (b) measuring the time between when the apparatus (215) was last drained of liquid (30) and when it should be drained again, (c) measuring the time between when an empty apparatus (215) is interfaced with the first cartridge(s) (290) to begin filling the apparatus with liquid (30) and the time when it should be drained of the liquid (30). Draining the liquid (30) in these instances pertains to draining all of the liquid (30) from the apparatus (215). This embodiment includes without limitation, the apparatus (215) having the ability to sense, detect, interpret, or determine, with one or more sensor(s) known to those skilled in the art, various activities, status, or conditions such as, but are not limited to, (a) the interface of one or more cartridge(s) (290) or other means to hold liquid (30), with the apparatus (215), (b) the liquid (30) level(s) in any reservoir(s) (40), (c) the opening or closing, or any position or state, of one or more valve(s) (660) to empty the apparatus of any liquid (30) that could be used to generate aerosol (200), (d) the movement or presence of any liquid (30), object, or mechanism, resulting from the emptying of the apparatus (215). The sensor(s) can communicate information with a PLC(s) (315) in a manner known in the art, and the PLC(s) (315) can use that information to help determine the length of time the liquid (30) may be utilized until it must be drained or discarded. The PLC(s) (315) can be programmed to accomplish these tasks in a manner known to those skilled in the art. The PLC(s) (315) can, without limitation, be programmed so that the apparatus will enter into a fault or error condition, or shut down one or more functions, and communicate an audible or visual signal to the operator, as well as communicate with other PLC(s), if a period of time has elapsed where the liquid (30) should have been fully drained but was not. This feature prevents the use of liquid (30) that has, without limitation, exceeded its usefulness for various reasons known to those skilled in the art. All communication between either the PLC(s) or the operator can transpire in a manner known in the art. In addition, any information or data can be communicated to or from the apparatus (215) by means such as, but not limited to, any human-machine-interface (HMI) (320), any terminal and its images, any buttons, any buttons and associated lights, any voice command(s) and directions, or any audible signal. The apparatus (215) can, without limitation, also require the operator to acknowledge any error or fault messages, apparatus status queries, or if any action was taken by the operator. The proper, necessary or effective period of time in which the liquid (30) can be used before it needs to be fully drained, is entered into the PLC'(s)' (315) programming in a manner known to those skilled in the art.

[0300] According to an embodiment illustrated in FIGS. 12, 13, 20, 29 and 37, the apparatus (215) can be designed and constructed so that any of its part(s), component(s) or space(s) that will increase in temperature from the operation of the apparatus (215) may be cooled, or any heat that is generated by one or more part(s) or component(s) or any related part(s) can be removed or displaced from the apparatus (215) either collectively or individually. The apparatus (215) in the present invention can be operated from various locations including, but not limited to, within the same area (210) in which the aerosol (200) is administered or applied. The operation of the apparatus (215) in an environment in which the aerosol (200) is applied can introduce various engineering challenges, including, but not limited to, cooling the aforementioned part(s) or component(s) and their related part(s), or surrounding atmosphere(s) (740) in a way that does not: (a) damage the apparatus, (b) damage any part(s) or component(s) of the apparatus (215), or (c) introduce a safety hazard. Cooling the aforementioned part(s) or component(s) and their related part(s), or surrounding atmosphere(s) (740) while utilizing as little or no amperage as possible is also, without limitation, another engineering challenge addressed in the current invention. Without limitation, many component(s) of the apparatus (215), including but not limited to, any electrical or electronic parts, may not be cooled by aerosol (200) laden air from outside of the apparatus (215). Aerosol (200) laden air/gas may cause electrical problems, electrical hazards, or cause damage to the apparatus (215) or its component(s) or part(s).

[0301] Without being limited, the various component(s) or part(s) of the apparatus (215) including, but not limited to any, electrical system(s), drive electronic(s) (645), blower(s) (180), pump(s) (130), or other part(s) or component(s) of the apparatus (215), and their related part(s), can be located in various ways including, but not limited to, locating the components individually or collectively in an enclosure(s) (345) that is impervious to things such as, but not limited to, humidity, dust, liquid, and aerosol. In addition, and without limitation, the atmosphere or various component(s) or part(s) of the apparatus (215) including, but not limited to any, electrical system(s), drive electronic(s) (645), blower(s) (180), pump(s) (130), or other part(s) or component(s) of the apparatus (215), and their related part(s), inside of the enclosure(s) (345), can be directly or indirectly cooled by means known to those skilled in the art. This means for cooling can include, but is not limited to, the use of, circulated coolant liquid, or refrigerated air. Any heat that is generated in the creation of the refrigerated air or that is removed from the enclosure(s) (345), the atmosphere inside of the enclosure(s) (345), or any part(s) or component(s) inside of the enclosure(s) (345), can be transferred to any air stream or direct to the atmosphere surrounding the apparatus (215).

[0302] Without limitation, the PLC(s) (315) can monitor the temperature of any surface(s) or atmosphere(s) (740) within the apparatus (215) with input from one or more of any temperature sensing devices or air/gas temperature sensing device(s) (650). The PLC(s) (315) can activate whatever means necessary to start, maintain, or stop any cooling activities or actions for any part(s), component(s), or atmosphere(s) of the apparatus (215), to maintain any desired or necessary temperature.

[0303] It is preferred, without limitation that the heat is transferred to an air/gas stream and this air/gas stream is the same air/gas stream (745) that is used to move the generated aerosol (200) out of the apparatus (215). The heat can be transferred to the air/gas stream (745) in one or more locations of the apparatus (215) including, but not limited to, inside any reservoir(s) (40), or inside any pipe(s) (685) before or after the blower(s) (180) that create the air/gas stream (745) that moves the aerosol (200) from the apparatus (215). It is also preferred, without limitation, that the heat generated by the various component(s) or part(s), especially any drive electronics (645) that operate the transducer(s) (10), be transferred to one or more heat sink(s) (750) having one or more fin(s) or other means known in the art to enhance cooling. Without limitation, the heat sink(s) can also interface and transfer heat from any coolant liquid or circulated coolant liquid that is used to cool any part(s), component(s), or atmosphere in a manner known in the art. The heat sink(s) (750) can be positioned anywhere in the air stream (745), before or after the blower(s) (180), so that at least the fin(s) or other cooling enhancement(s) (800) is placed or positioned in the air stream (745). The interface between any heat sinks or other means to transmit heat into the air stream (745) can be sealed in a manner known in the art. It is also preferred without limitation, that the heat sink(s) (750) that interfaces with the drive electronics (645) is interfaced with the top of the reservoir(s) (40) in which the transducers(s) (10) is located, and the heat sink(s) (750) is effectively positioned and sealed in place with one or more clasps (795). Without limitation, the various part(s) and component(s) of the apparatus (215) can interface with any heat sink(s) (750) in any orientation(s), layout(s), and with any methods known to those skilled in the art.

[0304] According to an embodiment, the apparatus (215) can be designed and constructed so that any of its exterior skin, walls, or surfaces (755) that can be exposed to the administered or deployed aerosol (200), are prevented from becoming warmer in temperature than the temperature of the atmosphere surrounding the apparatus or other surfaces surrounding the apparatus (215). This is important considering the potential operating environments of the apparatus (215). The book entitled, “Aerosol Technology” by William C. Hinds (1982), which is incorporated herein by reference in its entirety, including any references cited therein, teaches that, “When a temperature gradient is established in a gas, the aerosol particles in that gas experience a force in the direction of decreasing temperature. The motion of the aerosol particle that results from this force is called thermophoresis (page 153).” William C. Hinds (1982), also taught, “The earliest studies of thermophoresis were empirical studies of the dust-free layer observed around a heated object, such as a metal rod immersed in smoke. The smoke particles appear to be repelled by the heated object and form a particle free layer usually less than 1 mm thick, with a well-defined boundary (page 153).” This embodiment is advantageous for reasons including, but not limited to, it can prevent the aerosol (200) from being repelled from the exterior skin, walls, or surfaces (755) of the apparatus (215) in situations where the apparatus (215) is operating within the area (210) in which the aerosol (200) is administered or deployed and where it is needed or required that the exterior skin, walls, or surfaces (755) of the apparatus have contact with the aerosol (200). This embodiment includes, without limitation, constructing the apparatus (215) so that the exterior skin, walls, or surfaces (755) of the apparatus (215) are insulated from heat in various ways, including, but not limited to, applying one or more layers of insulating material (760) to the inside or outside of the exterior skin, walls, or surfaces (755) of the apparatus (215), constructing the exterior skin, walls, or surfaces (755) of the apparatus (215) so that they are double walled with a layer of insulation (765), including air/gas, in the middle of the said walls, or enclosing the components or parts that can increase in temperature, inside a sealed, insulated, or both insulated and sealed, enclosure, and then placing that enclosure inside of another sealed or unsealed enclosure that can also be insulated or not insulated.

[0305] According to an embodiment, object(s), the atmosphere(s) in which they reside, or any surfaces in the area targeted (210) for the administration or deployment of an aerosol (200), can be cooled or have their/its temperature decreased, before, or during the time when, the aerosol (200) is administered. This embodiment should not be confused with what was taught by U.S. Pat. No. 4,512,951 (Koubek at al., 1983), which is incorporated herein by reference in its entirety, including any references cited therein. Koubek et al., 1983, taught a method of sterilization where a liquid of aqueous hydrogen peroxide is vaporized, and the uniformly vaporized mixed hydrogen peroxide-water vapors are delivered into an evacuated sterilizer chamber, and the articles to be sterilized are cooled prior to the introduction of the vapor (or are cooled by the evacuation of air from the sterilizing zone) to a temperature below the dew point of the entering vapors. The condensing vapor deposits a film of liquid on all such cool surfaces (col 2, line 40-51). Koubek et al., 1983, also mentions in claim 2 that the result of vaporization was a mixed “gaseous vapor” consisting of hydrogen peroxide and water vapor free of solid contaminants. The present embodiment is intended for a completely different application and purpose since it is related to using principals of aerosol (200) behavior to, without limitation, increase the efficacy or performance of the process of the present invention, and not the condensation of a gas as taught in the prior art.

[0306] Basic principles applied in this embodiment are taught in the book entitled, “Aerosol Technology” by William C. Hinds (1982), which is incorporated herein by reference in its entirety, including any references cited therein. Without limitation, the cooling of the said object(s), surfaces, or environment or atmosphere, within the targeted area (210), in the present invention, can accentuate the performance or efficacy of the aerosol (200) generated by the apparatus (215) in the present invention. In addition, and without being limited to a mechanism or method, the aforementioned principles taught by William C. Hinds (1982), show that the efficacy, efficiency, and performance of the process in the present invention can be further increased by introducing an aerosol (200), consisting of a heated liquid (30), into an environment or targeted area(s) (210) with cooled surfaces.

[0307] The cooling of object(s), surface(s), space(s), environment(s), or atmosphere(s), within a targeted area(s) (210), can be accomplished with any means except by decreasing the pressure or pulling a vacuum on an enclosed area that is sufficient enough to decrease the temperature of the surfaces or atmosphere within that enclosed area. Creating a vacuum in an enclosed area and applying an aerosol was taught in the prior art by U.S. Patent Application No. 2005/0042130 A1 (Lin et al., 2003). However, Lin et al., was silent with respect to cooling any surfaces within the sterilization chamber or targeted area, and only mentioned the vaporization of the applied aerosol as being any enhancement or advantage that further vacuum past 5 torr would provide (pg. 2 paragraph 28). The vacuum utilized by Lin et al., (pg. 2 paragraph 28) to obtain data, was intended to move the aerosol through the sterilization chamber. In addition, using a vacuum to cool object(s), surfaces, or environment or atmosphere, within a enclosed area, would not be desired in this embodiment due to the complexity and expense involved in designing a chamber for the necessary vacuum and the expense of acquiring the necessary pump, which is all known to those skilled in the art. It is desired that another means for cooling object(s), surfaces, or environment or atmosphere, within a targeted area(s) (210), other than utilizing a vacuum, be utilized.

[0308] As shown in FIGS. 38-41, it is preferred, without limitation, that the targeted area(s) (210)) and its atmosphere, environment, objects, or any of the surfaces within the targeted area(s) (210), be cooled with air or gas that is cooled or chilled in a manner known to those skilled in the art. It is further preferred that the air or gas is cooled or chilled with one or more chill coils or refrigerated air systems (770) that are known to those skilled in the art. The means (770) to chill or cool the air or gas can be, without limitation, attached to the apparatus (215) in the present invention, be separate from the apparatus (215) and connect with one or more pipe(s) (810) or outbound cooled air pipe(s) (780) or inbound air pipe(s) (785) that connect with the targeted area(s) (210), or it can be part of or positioned anywhere within the space(s) or targeted area(s) (210) to be treated, and it can be controlled by one or more PLC(s) (315) or remote PLC(s). Without limitation, any pipe(s) that lead to (780) or from (785) the source of the refrigerated or cooled air can be separated from the targeted area (210) with one or more valve(s) (815) that can be controlled by one or more PLC(s) (315) or remote PLC(s). Without limitation, one or more valve(s) (815) may also be positioned at any location between the location where the administered air/gas or aerosol enters any pipe(s) (780) (785) or targeted area(s) (210) and the aerosol generating apparatus (215), and can be controlled by one or more PLC(s) (315) or remote PLC(s). The said valve(s) (815)(775), pipe(s) (220), or other related part(s) or component(s) can all be constructed from any material that is compatible, and suitable for use with the liquid (30). Without limitation, the amount or duration of air or gas that is flowed into or recirculated through the targeted area(s) (210), the locations that the air or gas is flowed into our out of the targeted area(s) (210), the temperature of the air or gas, as well as the temperature of the surfaces within the targeted area(s) (210) can vary depending on variables such as, but not limited to, the application, the level of performance that is desired, desired application time, as well as the volume of the targeted area(s) (210). Without limitation, the temperature of the atmosphere, surfaces, or space(s) in the targeted area(s) (210) can be cooled to at least nine degrees Fahrenheit below the temperature of the applied liquid (30). It is preferred, without limitation, that the temperature of the atmosphere, surfaces, or space(s) in the targeted area(s) (210) be cooled to at least nine to twenty-five degrees Fahrenheit below the temperature of the applied liquid (30). However, it is more preferred, without limitation, that the temperature of the atmosphere, surfaces, or space(s) in the targeted area(s) (210) be cooled to at least forty degrees Fahrenheit or lower. It is further preferred, without limitation, that the temperature of the atmosphere, surfaces, or space(s) in the targeted area(s) (210) be cooled to at least thirty-two degrees Fahrenheit or lower. The temperature of the applied liquid (30) of which the aerosol (200) is created or the temperature to which the aerosol (200) is heated with other means, can also vary. It is also preferred, without limitation, that the aerosol (200) is administered or deployed into an environment or targeted area(s) (210) where all heat emanating lights and/or machinery are turned off before or during the administering or deployment of the aerosol (200).

[0309] According to an embodiment, the apparatus (215) can be designed and constructed so that it can administer the generated aerosol (200) to a plurality of separate enclosed targeted areas (210). This can be accomplished, without limitation, through the use of one or more pipes (220) that emanate from or connect to the apparatus (215) and administer the aerosol (200) to the said enclosed areas (210). The flow of air or gas and aerosol (200) that emanates from the apparatus (215) may also, without limitation, be split various times, with one or more, or to one or more pipes (220), and the various pipes (220) can interface, or connect with one or more enclosed areas (210) in which the piped air/gas and aerosol (200) is administered. The one or more pipes (220) that emanate from the apparatus (215) can connect with one or more valve(s) (775) that can open or close one or more pipe(s) (220) that can be connected to one or more pipe(s) (220) or pipe junction(s) (790). The valve(s) (775) can be electronically opened or closed by one or more PLC(s) (315) connected to the apparatus (215), or one or more control PLC(s) external to the apparatus (215), all in a manner known to those skilled in the art. The said valve(s) (775), pipe(s) (220), or other related part(s) or component(s) can all be constructed from any material that is compatible, and suitable for use with the liquid (30). This embodiment does not encompass any configuration(s) or application(s) where the plurality of targeted areas (210) or areas where the aerosol (200) is deployed is within the same room, since this is already known to those skilled in the art. This embodiment may, without limitation, be used with any anti-pathogen/toxin/fungal/sporicidal agent(s) or substance(s) that may be in the form including but not limited to any liquid, gas, vapor, plasma, or aerosol, which is generated, delivered, moved, or administered, by any means.

[0310] According to an embodiment, the apparatus (215) can, without limitation, be designed and constructed so that the drive electronics (645), or any part of the drive electronics (645) that includes, but is not limited to, one or more signal generator(s), that emit or send electrical signal (herein referred to as “signal” or “signals”) to energize the transducer(s) (10), causing it to emit pressure (energy) of a desired character, can have the capability to emit or send various defined signal or signal range(s) for various defined period(s) of time during the lifespan of the transducer(s) (10) in order to, without limitation, continue to operate or energize the transducer(s) (10) at a frequency or within a frequency range in which the transducer(s) (10) are able to have an effective or functional output and/or operate at a frequency or in a frequency range where the transducer(s) (10) are able to operate at or within a range close to or at their maximum performance or aerosol (200) output. It is preferred, without limitation, that this embodiment pertains only to the new aerosol producing transducers (10) taught or claimed in co-owned and co-pending U.S. patent application Ser. No. 11/915,524 titled “Method And Apparatus For Optimizing Aerosol Generation With Ultrasonic Transducers”. However, it is more preferred, without limitation, that this embodiment pertain not only to the aerosol (200) producing transducers (10) taught in co-owned and co-pending U.S. patent application Ser. No. 11/915,524 titled “Method And Apparatus For Optimizing Aerosol Generation With Ultrasonic Transducers”, but also to other transducers (10) intended for aerosol (200) production, except for those that operate at the resonant frequency of the transducer (10). It is even more preferred, without limitation, that this embodiment pertains not only to the aerosol (200) producing transducers taught in co-owned and co-pending U.S. patent application Ser. No. 11/915,524 titled “Method And Apparatus For Optimizing Aerosol Generation With Ultrasonic Transducers”, but also to other transducers (10) intended for aerosol (200) production, except for those that operate at or near the resonant frequency of the transducer (10). The aforementioned exclusions to the preferences are needed since the current art, without limitation, encompasses the operation of a transducer (10) at its resonant frequency, as well as the design of the drive electronics (645) or ancillary components to sense any changes in the resonant frequency of the transducer (10), and to automatically adjust the frequency of the signal to the transducer (10) by way of the drive electronics (645) in order to compensate for, or match the transducer's (10) resonant frequency change. However, the prior art does not address the adjustment of the signal output from the drive electronics (645) to an aerosol (200) producing transducer (10) that has an effective or optimum operational frequency(s) above or below its resonant frequency that changes over time. One reason for this includes, without limitation, the complexity or difficulty to detect the optimum or effective operating frequency(s) for a transducer (10) at frequencies outside of the resonant frequency of a transducer (10), especially as it changes. This can be appreciated by those skilled in the art.

[0311] Aerosol (200) producing transducer(s) (10) in the present invention can have, without limitation, one or more frequency(s), group(s) of frequencies, or frequency range(s) in which they produce an aerosol (200) that can be characterized as effective, functional, or productive. The transducer(s) (10) utilized in the present invention can, without limitation, operate at one or more specific frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) are able to generate a greater amount of aerosol when compared to other frequency(s), group(s) of frequencies, or frequency range(s). Furthermore, the transducer(s) (10) utilized in the present invention can, without limitation, have or exhibit one or more specific frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) are able to generate not only an effective or functional output of aerosol (200), but generate the maximum amount of aerosol (200) or close to the maximum amount of aerosol (200) for each transducer(s) (10). Without limitation, for any frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) produce an effective, functional, or even maximum amount of aerosol (200) that is effective or functional, the aerosol output will decrease as the frequency of the signal sent to the transducer(s) (10) either increases or decreases from these established frequency(s), group(s) of frequencies, or frequency range(s).

[0312] Without being limited, any transducer (10) utilized in the present invention, may exhibit or have one or more additional frequency range(s) that encompasses the frequency(s), group(s) of frequencies, or frequency range(s) that will produce an effective, functional, or even maximum amount of aerosol. The magnitude of this frequency range can vary greatly, however, it is preferred without limitation, that this frequency range be within at least plus or minus 0.03 MHz (+/−0.03 MHz) from the frequency where the transducer(s) (10) generates the maximum amount of aerosol (200) or close to the maximum amount of aerosol (200) for a particular group of frequencies or frequency range, and is surrounded by frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) do not produce an effective or functional aerosol (200) output. It is more preferred, without limitation, that this frequency range is within at least plus or minus 0.05 MHz (+/−0.05 MHz) from the frequency where the transducer(s) (10) are able to generate the maximum amount of aerosol (200) or close to the maximum amount of aerosol (200) for a particular frequency, group of frequencies or frequency range, and is surrounded by frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) do not produce an effective or functional aerosol (200) output. It is even more preferred, without limitation, that this frequency range is within at least plus or minus (+/−0.08 MHz) from the frequency that the transducer(s) (10) are able to generate the maximum amount of aerosol (200) or close to the maximum amount of aerosol (200) for a particular frequency, group of frequencies, or frequency range, and is surrounded by frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) do not produce an effective or functional aerosol (200) output.

[0313] It has been observed, without limitation, that the transducer(s) (10) in the present invention, can have multiple, separate, or independent, frequency(s), group(s) of frequencies, or frequency range(s), where the transducer(s) (10) are able to generate an effective, functional, or productive aerosol (200) output. In addition, and without limitation, it has been further observed that in between these frequency(s), group(s) of frequencies, or frequency range(s), the transducer(s) (10) do not produce an effective or functional amount of aerosol (200).

[0314] It is important to note that the frequency or frequency range(s) in which the transducer(s) (10) produces either the maximum amount of aerosol (200) and/or an effective or functional amount of aerosol (200) can, without limitation, vary, and that it can be at or close to the resonant frequency of the transducer(s) (10) or anywhere above or below the resonant frequency of the transducer(s) (10). Resonant frequency can refer in this embodiment to either the resonant frequency of a free unmounted transducer(s) (10) or a transducer(s) (10) that has been mounted or assembled.

[0315] The resonant frequency of a transducer(s) (10) can, without limitation, increase due to age or other variables known to those skilled in the art. The nature of this change in resonant frequency can vary depending on variables known to those skilled in the art. As the resonant frequency of the transducer(s) (10) increases, the frequency range(s) in which the transducer(s) (10) would produce either the maximum amount of aerosol (200) and/or an effective or functional amount of aerosol (200) can, without limitation, also increase.

[0316] Referring now to FIGS. 42-45, the drive electronics (645), or any part of the drive electronics (645) that includes, but is not limited to, one or more signal generator(s) or ancillary components, used in the present invention can, without limitation, compensate for this shift or increase in frequency, and continue to operate the transducer(s) (10) at a frequency or frequency range where they produce either the maximum amount of aerosol (200) and/or an effective or functional amount of aerosol (200). This does not pertain to the prior art that encompasses the operation of a transducer (10) at its resonant frequency, as well as the design of the drive electronics (645) or ancillary components to sense any changes in the resonant frequency of the transducer (10), and to automatically adjust the frequency of the signal to the transducer (10) by the drive electronics (645) in order to compensate for, or match the transducer's (10) resonant frequency change. However, due to, without limitation, the complexities or limitations involved with this mode of operation or its successful execution or implementation, the following techniques can also be applied to aerosol (200) producing transducer(s) (10) that operates at or near its resonant frequency. This may be accomplished in ways including, but not limited to: (a) switching from one or more crystal(s) (825) that is initially used to generate one specific frequency or specific frequency range, to one or more different crystal(s) (830) that is used to generate other specific frequency(s) or specific frequency range(s). This can, without limitation, occur numerous times, for various durations of time, over a period of time; or (b) switching from one or more signal generator(s) (835) that is initially used to generate one specific frequency or specific frequency range, to one or more different signal generator(s) (840) that is used to generate other specific frequency(s) or specific frequency range(s).

This construction may, without limitation, increase the cooling efficiency of the means to dehumidify (2040) by increasing the cooled surface area.

[0342] In another embodiment, any liquid filtered from the air, or condensed by the chill coil(s) (2080) or any connecting metal filter material or mesh, can without limitation, be collected in a common collection container.

[0343] In another embodiment, the means to dehumidify (2040) an area in which the aerosol (200) is administered is without limitation, designed and built so it can receive any type of signal known to those skilled in the art, and this signal may cause the means to dehumidify (2040) to switch or direct the air flowing into or through any filter known to those skilled in the art, that is able to effectively remove any chosen or selected gas(s) or vapor(s) (2090) from the air in the treated area(s). It is preferred, without limitation, that this filter (2090) is constructed from activated charcoal in a manner that is known to those skilled in the art, and one or more valves (2100), or other means known to those skilled in the art, closes thus forcing air through a separate channel that leads to the filtering (2090) means.

[0344] In another embodiment, the means to dehumidify (2040) an area in which the aerosol (200) is administered or deployed, can be, without limitation, designed and built so the operator can program or select various options including, but not limited to, (a) any time delay between when a certain humidity level or range of humidity is detected and when the dehumidifier would commence the dehumidification process, (b) any humidity level where the means to dehumidify (2040) would stop the dehumidification process, (c) any duration of time for moving, switching, or directing the air flowing into or through any filter (2090) that is able to effectively remove any targeted gas(s) or vapor(s) from the treated area(s), (d) any duration of time that the means to dehumidify (2040) would operate and dehumidify the room.

[0345] According to an embodiment shown in FIGS. 59-63, a means to effectively or efficaciously cover various types of inbound or outbound air vents and/or any surrounding area or surfaces of the vents (2120), in the treated area can, without limitation, be used in concert with the aerosol generating apparatus (215) or any aerosol or vapor generating apparatus, and prevent or limit the movement of air, gas, aerosol (200) and vapor(s) through these vents (2120). This vent covering assembly (2300) consists of parts including, but not limited to, a means to cover the vent (2110), any material extensions (2160) that are needed to directly or indirectly attach to the cover (2110) so that it will have sufficient clearance and cover any protruding vent (2120) parts (3010), sealing material (2130) that can seal the cover (2110) to the vent (2120) or any surface(s) surrounding the vent, any one or more pole(s) (2140) which can, without limitation, be adjusted or modified for length by the operator, a means to directly or indirectly connect the pole(s) to the vent cover (2150), one or more means to directly or indirectly connect (2500) the pole(s) (2140) to the floor or any other surface (2400). This assembly of parts can be made of any mechanically, structural, and chemically suitable materials that are known to those skilled in the art for this application.

[0346] Any parts used to construct the vent covering assembly (2300) can be constructed from various materials such as, but not limited to, stainless steel, glass, polymer, polyolefin, cellulose, or even natural or manufactured fibers that are either coated or uncoated. It is preferred, without limitation, that the vent covering assembly (2300) is constructed from one or more polymers that can include, but is not limited to, PVC, polycarbonate, polypropylene, and HDPE. The materials used to construct the vent cover (2110) or extension(s) (2160) may be rigid, semi-rigid, flexible, or pliable. It is preferred, without limitation, that the vent cover (2110) and any needed extension(s) (2160) are constructed from rigid PVC. The seal material (2130) can be any material that can create an effective seal with/against any materials that it contacts. It is preferred, without limitation, that the seal material (2130) is constructed from materials such as, but not limited to, Viton, or EPDM, with a durometer of at least 10.

[0347] According to another embodiment, the vent cover (2110) and/or its extensions (2160) can, without limitation, be constructed from, or be molded with, any material that can create an effective seal, or otherwise function as the seal, which negates the use of a separate seal material and/or seal layer (2130). This represents the vent cover (2110) in its simplest form. In this case, the vent cover (2110) and/or its extensions (2160) is designed and constructed so that it incorporates the purpose, performance, traits, attributes, and characteristics of both the seal material and/or seal layer (2130) and the vent cover (2110) and/or extensions (2160).

[0348] In another embodiment, any parts connected directly or indirectly to the means to cover the vent (2110) can be adjusted for height in order to create or maintain effective compression on any seal that is formed to effectively or efficaciously seal or cover the air or gas vents (2120). It is preferred, without limitation, that the one or more pole(s) (2140) is constructed in a manner known to those skilled in the art, so that its length can be adjusted and locked into position once sufficient or effective force is exerted onto any part of the vent covering assembly (2300) such as, but not limited to, a means to cover the vent (2110) and/or the seal material (2130).

[0349] It is preferred, without limitation, that the means to cover the vent (2110) is any shape, size, construction, or geometry that is sufficiently large enough so that the sealing means and/or seal material (2130) can effectively seal to or around any air vents (2120). It is even more preferred, without limitation, that the means to cover the vent (2110) is in the shape of a plate or bowl. This means to cover the vent (2110) can, without limitation, have one or more structural supports that are positioned in a manner known in the art to prevent any unwanted flexing of the means to cover the vent (2110) during use. The means to cover the vent (2110) can also, without limitation, have extensions (2160) directly or indirectly attached to allow the various vent cover components (2170) to effectively fit over the vent (2120) and any protruding vent parts (3010). The extensions (2160) can be made of the same materials as the means to cover the vent (2110), and have any thickness, width, length, height, geometry, or construction. The extensions (2160) can, without limitation, follow the outline of the means to cover the vent (2110).

[0350] The seal material (2130) can be attached to the vent cover (2110) or its extensions (2160) in various ways known to those skilled in the art. The seal material (2130) can be made from any compatible and suitable material. However, it is preferred, without limitation, that the seal material (2130) consists of any suitable material and design that has sufficient compression and/or compliance to form an effective seal when it is compressed or contacts between the vent cover (2110) and/or extension(s) (2160) and the vent (2120) or any surface surrounding the vent. It is even more preferred that the seal material (2130) has absorbent properties. A lip or other effective means can also be built or formed around the seal material (2130) to catch or hold any liquid if it is compressed out of the seal material (2130).

Any aerosol (200) or vapor generating means can be used in this embodiment. The aerosol and/or vapor is delivered via one or more tube, pipe, or conduit (herein called “application wand” or “wound wand”) (3190) which can be any, without limitation, angle, size, length, orientation, diameter, width, or geometry. The wound wand (3190) can be connected to the aerosol (200) generating apparatus (215) in various ways knows to those skilled in the art. The wound wand (3190) can also be designed and constructed so that it can be easily connected or disconnected from any aerosol and/or vapor (200) supply line(s) (3200), and it can be effectively cleaned, sterilized, or disinfected, in a manner known to those skilled in the art. Various types of flexible pipe or tubing (3200) can, without limitation, connect to the application wand (3190) in a manner known to those skilled in the art.

[0371] It is further preferred, without limitation, that one or more perforations (3220) can be located at any location(s) on the application wand (3190). The perforations (3220) can be, without limitation, any size, pattern, shape, angle, geometry, and any orientation. The application wand (3190) can also be designed to interface with interchangeable tips (3230) that vary in attributes such as, but not limited to, length, diameter, any exit orifice (3210) attributes, number or size of perforations (3220), angle of perforations (3220). The interchangeable tips (3230) can connect to the application wand (3190) in a manner known to those skilled in the art. The exit orifice (3210) can be, without limitation, any shape, size, geometry, in order to develop an effective and efficacious device.

[0372] According to an embodiment, the application wand (3190) can, without limitation, incorporate any means anywhere on its surface which when actuated or activated (3240), controls and/or stops the flow of aerosol (200) and/or vapor that emanates from the application wand (3190) or any of its interchangeable tips (3230). These control functions can be separate or combined control interfaces. These means (3240) can, without limitation, be any mechanical/electrical means known to those skilled in the art.

[0373] According to an embodiment, any parts used to construct the application wand (3190) can be constructed from various materials such as, but not limited to, stainless steel, glass, polymer, polyolefin, cellulose, or even natural or manufactured fibers that are either coated or uncoated. It is preferred, without limitation, that the application wand (3190) is constructed from one or more polymers that can include, but is not limited to, PVC, polycarbonate, polypropylene, and HDPE. The materials used to construct the application wand (3190) may have any rigidity. Any surfaces of the application wand (3190) may have any electrical charge.

[0374] According to another embodiment, the application wand (3190) can, without limitation, incorporate any means, known to those skilled in the art, to mount or attach to, integrate, attach, or combine, either temporarily or permanently, any devices or to any devices, such as, but not limited to any, source of light, means to present or create suction, camera or any other imaging or video device, cauterization, robotic grips or hands, scalpel, means for suture application or removal, or any means for applying electrical shock or pulses.

[0375] Any, (a) liquid, (b) mixture or solids suspended in any liquid, (c) solution, (d) medication, (e) organisms, (f) anti-pathogen/toxin/fungal/sporicidal agent(s) or substance(s), (g) micro machine(s) or structure(s), (h) nano machine(s) or structure(s), may also, without limitation, be used in these embodiments.

[0376] According to an embodiment shown in FIGS. 70-73, a means (herein called ‘multi interface assembly’) (3320) is designed and constructed to cover or at least isolate or prohibit the whole or at least a part of, one or more of any means that enable movement for the apparatus (215) or any other equipment or accessories located in the targeted or treated area (3310) such as but not limited to any wheels, tracks, rollers, rolling means or other movable means (herein collectively ‘wheel(s)’) (3330), from having any contact with any floor or surface that they rest on (herein called ‘floor’) (3340) in various situations such as, but not limited to, when the apparatus (215) or other equipment or accessories is moved, stopped, or held in a static or semi-static position, and the wheel(s) (3330) are in direct or indirect contact with one or more of any absorbent material(s) (3350) that can hold, contain, or absorb any liquid. The absorbent materials (3350) or any construct containing absorbent materials (3350) are either treated or pretreated in various ways known to those skilled in the art, with any liquid agent(s), so that both the wheel(s) (3330) and the floor (3340) can come in contact with the liquid agent(s). It is preferred, without limitation that the absorbent material(s) (3350) is saturated with the same liquid (30) that is generated into aerosol (200) in the present invention.

[0377] In the first part of this embodiment, the multi interface assembly (3320) can include one or more materials or parts, where the wheel(s) (3330) are moved or rolled onto or into one or more basin or indentation (herein called “basin”) (3360). One or more walls or edges of any basin(s) (3360) can, without limitation, be formed of any angled material or ramps (3690), of any angle, size, construction, or length, to facilitate unhindered and easy movement of any wheel(s) (3330) into and out of the basin(s) (3360). The multi interface assembly (3320) can be made of one or more materials such as, but not limited to, stainless steel, glass, cellulose, polyolefin, paper, polymer, natural or manufactured fibers or materials, that may be coated or uncoated, or constructed with combinations of these materials, or other materials known in the art. However, any of the materials that can have any contact with the wheel(s) (3330) and any floor surface(s) (3340) shall have absorbent properties and can, without limitation, be any thickness and have any durometer. The basin(s) (3360) can, without limitation, be constructed from, or lined with, absorbent material(s) (3350) of any thickness, and it can have any dimensions, including any depth. The basin (3360) can, without limitation, have one or more directly or indirectly connecting lips or ramps (3370) of various length and angle, extending into one or more directions, to facilitate easier entry of the wheel(s) (3330) into the basin (3360), and/or onto the multi interface assembly (3320), from the floor (3340). This can, without limitation, help the operator so that they do not have to lift the apparatus to position the wheel(s) onto the absorbent material(s) (3350). The absorbent material(s) (3350) can be pretreated with one or more liquid agent(s), or the operator can moisten the absorbent material(s) (3350) with one or more liquid agent(s) in a manner known in the art, before or after the wheel(s) (3330) have had contact with the absorbent material(s) (3350). The multi interface assembly (3320) may, without limitation, also have one or more of any tube, duct, pipe, conduit, tunnel, pathway, or connection (herein called “basin tube”) (3380), that connects any part of the basin (3360), or any other structure or component that directly or indirectly connects to any part of any basin (3360), with any of the absorbent material(s) (3350) that can have contact with any floor surface(s) (3340), so that any liquid or moisture may be transported, moved, or flow, at any rate or speed, from the basin (3360) to any of the absorbent material(s) (3350) contacting any floor (3340) surfaces. It is also possible, without limitation, to exclude the basin (3360), but keep one or more of any other attributes of the multi interface assembly (3320), which represents the multi interface assembly (3320) in its simplest form.

[0378] The multi interface assembly (3320) may, without limitation, also have one or more ridges (3390) of effective height that protrude vertically or on any effective angle to perform functions such as, but not limited to, prohibiting movement of the wheel(s), and maintaining the position of the wheel(s) (3330) on the absorbent material(s) (3350). The ridges (3390) may also be lined with absorbent materials (3350). The multi interface assembly (3320) may, without limitation, also have one or more handles or grip points attached or built into its design to facilitate easier handling.

[0379] According to an embodiment shown in FIGS. 74-75, the multi interface assembly (3320) may, without limitation, also include one or more removable absorbent material(s) (3350), and can be, without limitation, be directly attached to any wheel(s) (3330) and held or positioned into place with a variety of methods or combination of methods known in the art, including, but not limited to, the use of one or more pieces of elastic material (3400) around one or more edges of the absorbent material(s), and/or the use of one or more string laces or elastic bands or other material (3410) connected to the inside diameter of the absorbent material(s) assembly. This version represents the multi interface assembly (3320) in its most simple form.

[0380] According to an embodiment shown in FIG. 76, the apparatus (215) or any aerosol generator can, without limitation, be designed and constructed so that one or more filters (3420), known to those skilled in the art, can be connected to any parts of the plumbing anywhere in the design of the apparatus (215), as well as located anywhere inside of the various tanks used in the design of the apparatus (215). The filter(s) can, without limitation, be disposable and they can be designed for use in the apparatus (215), in a manner known to those skilled in the art, so that they are effective and easy to replace. In addition, all of the various devices and plumbing in the apparatus (215) such as, but not limited to any, feed tank(s) (280), reservoir(s) (40), feed tank valve(s) (300), pump(s) (130), filter(s) (3420), blower drain valve (3430) and system drain valve(s) (660), can be located and designed so that when the apparatus (215) is drained of all of the liquid agent(s) within it, it may be fully emptied of all liquid. This can, without limitation, facilitate thorough cleaning of the apparatus (215) and reduce any potential for damage resulting from any freezing liquid. Furthermore, the apparatus (215) may, without limitation, have one or more cleaning function(s) or program(s) designed into its hardware and/or system operating software so that all of the various valves in the system can simultaneously open in order to help purge or entirely drain the apparatus (215). This functionality can also, without limitation, be used to drain the various systems and plumbing of the apparatus (215) as it is being flushed and cleaned out.

[0381] According to an embodiment shown in FIGS. 76-77, the apparatus (215) or any aerosol generator can, without limitation, be designed and constructed so that any enclosure(s), cover(s), or housing(s) (herein called “blower housing”) (3440), that enclose or hold any fan, blower, or other source of pressurized air (180), including, without limitation, any attached conduit(s), pipe(s), or tubing, may be drained of any liquid that may build up in these areas during operation or cleaning of the apparatus (215). This liquid can, without limitation, be drained, in a manner known to those skilled in the art, to any tank(s), holding tank(s), drain port(s), or tank(s) and/or reservoir(s) (40) where the aerosol (200) is created. The apparatus (215) can be plumbed in various ways known to those skilled in the art, so that this liquid can be fully drained and removed from the apparatus (215) or any device. The liquid can also, without limitation, be drained back into the tank(s) or reservoir(s) (40) where the aerosol (200) is created.

[0382] According to an embodiment shown in FIGS. 78-79, one or more of any pipe(s), tube(s), hose(s), or other enclosed or semi-enclosed means for transporting any amount of generated aerosol (herein collectively “fog tube(s)”) (3450), are positioned within any tank or reservoir(s) (40) in which aerosol is created, and connect the inside of the reservoir(s) (40) with their exterior and/or the exterior of the apparatus (215). The reservoir(s) (40) are connected to one or more of any fan, blower, or other source of pressurized air (180) that can, without limitation, move any quantity of air at any rate into and through the reservoir(s). It is preferred, without limitation, that a blower (180) is used that has an output of at least 90 cubic feet/minute (cfm) or more. It is more preferred, without limitation, that a blower (180) is used that has an output of at least 150 cfm or more. It is even more preferred, without limitation, that a blower (180) is used that has an output of at least 250 cfm or more. It is very preferred, without limitation, that a blower (180) is used that has an output of at least 350 cfm or more. It is very preferred, without limitation, that a blower (180) is used that has an output of at least 450 cfm or more. In addition, the tanks or reservoir(s) (40) can be, without limitation, sealed, semi-sealed, or unsealed. It is preferred, without limitation, that the tanks or reservoir(s) (40) are sealed.

[0383] One or more of the fog tube(s) (3450) can, without limitation, connect or pass through one or more plate(s) (3460) or other structure, that can be attached to various parts of the apparatus (215) or any reservoir(s) (40). It is preferred, without limitation, that the plate(s) can be designed and constructed so that they and any attached fog tube(s) (3450) can be easily removed from the apparatus (215) or reservoir(s) (40). This can help with activities such as, but not limited to, installation, removal, and cleaning, of the plate(s) (3460) and the fog tube(s) (3450). It is preferred, without limitation, that the plate(s) (3460) and the fog tube(s) (3450) are constructed so that they form a sealed assembly when they are directly or indirectly attached to the apparatus (215) or any reservoir(s) (40).

[0384] The one or more open tube end(s) (3470) of each fog tube (3450) is positioned effectively and approximately above each transducer (10) or other source of the generated aerosol (200). However, the one or more open tube end(s) (3470) of each fog tube (3450) can also be located, without limitation, effectively and approximately to any sides, or any other angle or angled aspect, relative to each transducer (10), other source of the generated aerosol (200), or any geyser or eruption formed on the surface of any liquid (30) above any transducer (10). It is preferred, without limitation, that each open tube end(s) (3470) is horizontally angled above each geyser or eruption formed on the surface of any liquid (30) above any transducer (10), or other source of the generated aerosol (200).

[0386] In another part of this embodiment, the distance that each open tube end (3470) is positioned relative to each geyser or eruption formed on the surface of any liquid (30) above any transducer (10), or other source of the generated aerosol (200), is an important part of this embodiment and the present invention. It is preferred, without limitation, that each open tube end (3470) is positioned approximately 0 to 6 inches or more from the surface of any liquid (30) above any transducer (10), or other source of the generated aerosol (200). It is more preferred, without limitation, that each open tube end (3470) is positioned approximately 0.5 to 1 inches or more from the surface of any liquid (30) above any transducer (10), or other source of the generated aerosol (200).

It is most preferred, without limitation, that each open tube end (3470) is positioned approximately 3 to 4 inches or more from the surface of any liquid (30) above any transducer (10), or other source of the generated aerosol (200). Investigation in the laboratory has found that the maximum effective distance is approximately four (4) inches from the surface of the liquid agent(s) (30) above each transducer (10), when using one or more transducer(s) (10), and after that distance the performance, effectiveness, and/or efficacious, quickly diminishes.

[0387] In another part of this embodiment, the length and/or position of the fog tube(s) (3450) can, without limitation, change inside any reservoir(s) (40) to accommodate any changing liquid (30) levels and to maintain the effective distance of any open tube end(s) (3470) to the surface of any liquid (30) above any transducer(s) (10), or other source of the generated aerosol (200). This can, without limitation, be achieved in various ways including, but not limited to, designing and constructing the fog tube(s) (3450) so they are flexible or made from one or more movable or collapsible segments (3480), and the open tube end(s) (3470) are maintained at a specific distance from the surface of any liquid (30) through the use and any direct or indirect connection of one or more of any float(s) (3490) that can float on the surface of the liquid agent(s) (30) in the reservoir(s) (40).

[0393] In another part of this embodiment, any filter (3860) can be functionally located or attached along the path of any fog tube(s) (3450), or to the one or more external open tube end(s) (3500) of each fog tube (3450). The one or more of any filter(s) (3860) can filter the output or any air/gas and/or aerosol (200) before it leaves the apparatus (215). The filter(s) can remove any quantity or any size of aerosol particles. It is preferred, without limitation, that the filters remove any aerosol droplets below 3 microns in size.

[0394] According to an embodiment shown in FIG. 76, the apparatus (215) or any aerosol generator can, without limitation, be designed and constructed so that any of its inlets or intake orifices (255), or any air outlets, exit orifices, or openings (170), can have one or means (herein called “door(s)” (3510)) to effectively cover and/or seal closed one or more of these openings. It is preferred, without limitation, that these door(s) (3510) can effectively seal to keep any liquid, gases, or vapor from escaping from the apparatus (215). It is also preferred, without limitation, that the door(s) (3510) is designed and constructed in such a way so that it can effectively be opened and closed in a manner known to those skilled in the art. It is even more preferred that the door(s) (3510) are attached either directly or indirectly to the apparatus (215) via any type of hinge known to those skilled in the art. The door(s) (3510) can be removable, or permanently attached to the apparatus (215).

[0428] According to an embodiment, the apparatus (215) or other aerosol generator can, without limitation, be designed and constructed so that it can conduct, operate, or execute various operational steps or sequences. One or more of the following steps can also, without limitation, be bypassed either temporarily or permanently per the desires or needs of any operator or control input. Each step can vary for any length of time for any reason known to those skilled in the art. In addition the time between each step can also vary for any length of time for any reason.

[0429] The first step is aerosol generation and deployment of the aerosol (200) into the one or more targeted area(s) (3310). This step includes, without limitation, the additional step of heating the liquid (30) that will be aerosolized, to any preset temperature. The second step is giving the deployed aerosol (200) and any vapor component(s) adequate time to effectively and efficaciously move within the targeted area(s) (3310) and contact any surfaces in the targeted area(s) (3310), all in a manner known to those skilled in the art (also known as dwell time).

[0430] The third step is dehumidification. Dehumidification can be achieved in various ways known to those skilled in the art, and with any dehumidifier (2040). Any humidity level can be set as the target point for the dehumidification process to meet or achieve. Dehumidification can also, without limitation, consist of operating any rotating paddles (3570) as mentioned in the present invention, and this can, without limitation, be operated with our without any other dehumidification device(s) or methodologies. The fourth step is deodorization. This is achieved by using one or more UV light source(s) (3620) as described in the present invention. The fifth step is filtering the air with one or more of any filter(s) (2070) to remove any amount of any unwanted gases or vapor. Furthermore, the aerosol generating apparatus (215) may stop all other steps and enter into or start the dehumidification step at any time for any reason. The dehumidification step may be started for reasons including, but not limited to, the apparatus (215) or operator or other input, has detected a fault with any part or operation of the apparatus (215) or any other ancillary piece of equipment, an emergency stop has been actuated, or the operator has chosen to abort or stop the function of the apparatus (215). Finally, the operator of the apparatus (215) can, without limitation, manually operate the dehumidification step or deodorization step either any time before the aerosol (200) generating apparatus (215) has started to generate and deploy any aerosol (200), or any time after the treatment process(s) or entire operational cycle is complete.

[0431] According to an embodiment shown in FIGS. 92-93, a means (herein called “door seal”) (3730) is designed and constructed to cover, plug, or seal any space (herein called “door gap(s)”) (3750) that can exist between any door frame or door (herein called “door”) (3720) and any floor (3340) or other materials below it. The door seal (3730) can, without limitation, be friction fitted under and/or against either side of any door (3720). The door seal (3730) can, without limitation, be any length, width, height, and have any floor, doorway, or door interfacing geometries. The door seal (3730) can also be, without limitation, designed in a manner known to those skilled in the art, so that its length, width, or height, can be easily adjusted to accommodate and effectively seal with various doorway and door (3720) designs and sizes.

[0432] The door seal (3730) can, without limitation, be flexible, and have any durometer rating. It is preferred, without limitation, that the door seal (3730) has a durometer rating that allows it to be easily inserted under a door or at least effectively interfaced with one or more door gap(s) (3750). The door seal (3730) can, without limitation, be constructed from, fully covered, or at least covered on its critical interfacing surfaces, with one or more of any absorbent material(s) (3760) that can hold, contain, or absorb any liquid. Any absorbent material(s) (3760) can, without limitation, have any type, depth, length, and number, of textures or indentions, and can be any thickness or construction. The absorbent material(s) (3760) can be constructed from, without limitation, one or more materials such as, but not limited to, cellulose, paper, natural or manufactured fibers or materials, that may be coated or uncoated, or constructed with combinations of these materials, or other materials known in the art. The absorbent materials (3760) or any construct containing absorbent materials (3760) are either treated by the operator or pretreated in various ways known to those skilled in the art, with any liquid agent(s), so that the surfaces of the doorway and/or door(s) (3720) and the floor (3340) or any flooring or other materials under the door(s) (3720), can come in contact with the liquid agent(s). It is preferred, without limitation that the absorbent material(s) (3760) is saturated with the same liquid agent(s) (30) that is generated into aerosol (200) in the present invention. The door seal (3730) can also, without limitation, incorporate one or more handle(s) (3740) of various size, length, and shape, into its design to facilitate easier placement and retrieval.

[0433] According to an embodiment, the door seal (3730) can, without limitation, be designed and constructed to include one or more reservoir(s) or basin(s) (herein called “seal basin” (3770)) which can be either internally or externally located. They can be any size and shape and filled with any liquid agent(s). The seal basin(s) (3770) can also, without limitation, have one or more removable covers that can effectively directly or indirectly seal to the door seal (3730). The seal basin(s) (3770) may, without limitation, also have one or more of any tube, duct, pipe, conduit, tunnel, pathway, or connection (herein called “feed tube”) (3780), that connects any part of the seal basin(s) (3770), or any other structure or component that directly or indirectly connects to any part of any seal basin(s) (3770), with any of the absorbent material(s) (3760), so that any liquid or moisture may be transported, moved, or flow, at any rate or speed, from the seal basin(s) (3770) to any of the absorbent material(s) (3760).

[0434] According to an embodiment shown in FIG. 94, a means (herein called “odor remover tank”) (3790) can, without limitation, be designed and constructed so that air or gas from one or more targeted area(s) (3310) can be pumped, flowed, compressed, or moved, into and through one or more various types of liquids contained in one or more enclosed tanks or reservoirs (herein called “tank(s)”) (3820). The air or gas can also, without limitation, contain any amount of any aerosol (200). The liquid(s) (herein called “neutralizer liquid(s)”) (3810) held in the tank(s) (3820) can, without limitation, neutralize, degrade, or remove, any odors or vapors from the air, as well as neutralize or degrade any liquid agent(s) (30) that the aerosol (200) may contain. Any neutralizer liquid(s) (3810) can be utilized. It is preferred, without limitation, that the neutralizer liquid(s) (3810) is an aqueous solution containing any effective amount of sodium bicarbonate when the treated air or gas is from an area that is treated with an aerosol containing substances such as, but not limited to, hydrogen peroxide, or peroxyacetic acid (PAA).

[0435] It is preferred, without limitation, that one or more of any high capacity air/gas compressor(s) known to those skilled in the art, is used to move the air or gas from the treated area(s) (3310) into the neutralizer liquid(s) (3810). The air or gas can be pumped, flowed, compressed, or moved, through one or more of any adequate tube, duct, pipe, conduit, tunnel, pathway, or connection, anywhere into the neutralizer liquid(s) (3810) at any effective pressure or flow rate. The neutralizer liquid(s) (3810) can be maintained at any volume, depth, and temperature. The neutralizer liquid(s) (3810) can also, without limitation, be stirred at any time and for any duration in a manner known in the art. The air or gas may also be recirculated one or more times through the neutralizer liquid(s) (3810) before it is released from the odor remover tank (3790) out of an air outlet (3840) and back into the treated area(s) (3310) or vented into a separate area. Any air or gas can be, without limitation, processed by any effective or necessary filtering means (3850) known to those skilled in the art before it leaves any odor remover tank(s) (3790) or any connecting system of tube(s), duct(s), pipe(s), conduit(s), tunnel(s), pathway(s), or connection(s). All of the odor remover tank (3790) functions can, without limitation, be controlled directly or indirectly by any software, electronics, PLC (315), or HMI (320). The odor remover tank (3790) can be operated at anytime when it is needed or desired to remove any odors or vapor from the targeted area(s) or treated space(s) (3310). The odor remover tank (3790) device can be, without limitation, combined or operated with any aerosol (200) generating device or dehumidifier (2040).
