Display adjustably positionable about swivel and pivot axes

[0001] The present application is a nonprovisional patent application of, and claims priority under 35 U.S.C. section 119(e) to, U.S. provisional patent application Ser. No. 60/454,895, filed Mar. 14, 2003, which provisional patent application is incorporated by reference herein.

[0002] Modern healthcare providers are learning that true healthcare involves much more than perfunctory attention to physical ailments. The best care embraces the full spectrum of needs of a patient. A patient that is comfortable with attention and treatment is indeed likely to benefit from participation in preventive practices and regularly scheduled appointments for care. Indeed, preventive medicine is thought to be a key to the future in lowering healthcare costs and in improving quality of life.

[0003] A distraction from what may otherwise be an uncomfortable or awkward procedure can help a patient relax and can thereby reduce both physical and mental stress and increase the tolerance of the patient during a lengthy procedure. If improvements to the full experience of the patient can be achieved, then the patient is more likely to pursue elective care services. This may be of particular importance in, for example, the oral care industry where dentists have suffered since the conception of their craft against a reputation for providing needed but often uncomfortable services to patients.

[0004] Even routine healthcare services such as oral hygiene procedures can provide a less than optimal patient experience. Patients are typically at least bored while receiving such care. The overall experience of the patient could be substantially improved by some convenient arrangement for entertainment.

[0005] In addressing the need for patient distractions, many dentists now incorporate into the provision of healthcare the presentation of audio and/or video content to patients while the patients are receiving healthcare services. In this regard, computer monitors and televisions, headphones, and even virtual reality goggles are provided in order to provide patient distraction from dental procedures. The monitors and televisions are incorporated into the dental treatment rooms by positioning them into or on top of cabinets in the treatment rooms, or mounting them on arms attached to dental chairs. The view of these monitors and televisions provided to the patient, however, is less than optimal, as many dental procedures require the patient to be fully reclined in the dental chair. Headphones also inhibit effective communication between the patient and provider of the healthcare service during the procedure. Virtual reality goggles may be similarly obstructive and are not comfortable to some patients who experience claustrophobia.

[0006] Accordingly, a need continues to exist for improvements in the provision of healthcare and, especially, dental healthcare. This, and other needs, are addressed by one or more aspects of the present invention.

[0007] The present invention includes many aspects and features. Moreover, while many aspects and features relate to, and are described in, the context of the provision of healthcare, and especially dental healthcare, the present invention is not limited to use only in the provision of healthcare, as will become apparent from the following summaries and detailed descriptions of aspects, features, and preferred embodiments of the present invention.

Similarly, both elongate bars 40 are directly secured to a post portion 42 of the of the mounting member 32 by a second clamp bolt assembly and nut The mounting member 32 is removably attached via screws 44 directly to the electronic display 14 in fixed relation thereto.

[0057] The pivot arm 10 comprises a pair of parallel elongate members joined to form a four-bar-linkage parallelogram, and the pivot arm 10 is pivotable about a pivot axis 46 and another pivot axis 48. The pivot axis 46 passes through the distal end 16 of the pivot arm 10, and the pivot axis 48 passes through the distal end 24 of the pivot arm 10. As will be appreciated by one having ordinary skill in the art, the design of the pivot arm 10 is such that raising or lowering of the electronic display 14 by pivoting movement of the pivot arm 10 about both pivot axes 46,48 permits the swivel axes 22,30 to remain in parallel relation. In this regard, a subassembly 26 couples the pivot arm 10 to the electronic display 14, and includes a swivel 28 through which a swivel axis 30 passes, a mounting member 32, and an elongate member 34 extending between and connecting together the swivel 28 and the mounting member 32. The elongate member 34 is pivotably mounted to the swivel member 28 for pivoting movement about pivot axis 36. The elongate member 34 also is pivotably mounted to the mounting member 32 for pivoting movement about pivot axis 38. The elongate member 34 is rotatable about the swivel axis 30 and includes two elongate side bars 40. The coupling of the elongate member 34 to the swivel 28 includes a post that extends downwardly from the swivel 28, to which both elongate bars 40 are directly secured by a first clamp bolt assembly and nut. Similarly, both elongate bars 40 are directly secured to a post portion 42 of the of the mounting member 32 by a second clamp bolt assembly and nut The mounting member 32 is removably attached via screws 44 directly to the electronic display 14 in fixed relation thereto.

[0058] The swivel arm 12 preferably is mounted to a ceiling of a room but, alternatively, may be mounted to a wall or other support. This mounting may be accomplished by coupling the distal end 18 of the swivel arm 12 to a carriage 50. This coupling is accomplished by a swivel 52 such that the swivel arm 12 can be variably swiveled about a swivel axis 54 passing through the swivel 52, and a vertical member 57 that extends between and connects this swivel 52 to the carriage 50. The vertical member 57 is of sufficient mechanical strength to physically withstand the tensile, shear, and torsional forces of supporting the electronic display 14 and its coupling to the vertical member 57 in their suspension below the carriage 50. The swivel arm 12, in turn, includes sufficient mechanical strength to physically withstand the tensile, shear, and torsional forces of supporting the electronic display 14 and its coupling to the swivel arm 12 in their suspension below the carriage 50.

[0059] Each of the aforementioned swivels may include any suitable construction and arrangement of bearings, races, cones, axles, or bushings to allow rotation.

[0060] As best shown in FIG. 3, the carriage 50 itself is secured to a ceiling-mounted track 56 such that the carriage can 50 can be variably positioned along the overhead track 56 that extends generally parallel to the ceiling and that defines a translational axis. Translational movement of the carriage 50 along the overhead track 56 results in simple translational movement of, inter alia, the electronic display 14. The carriage 50 may be movably mounted to the track 56 by way of bearings, rollers, glide bushings, collars and shafts, or any suitable mechanical coupling allowing the carriage 50 to be variably positioned along the track 56.

[0061] As will be appreciated from the foregoing description, and as shown in FIG. 2, the swivel arm 12 is rotatable about the swivel axis 54, whereby the swivel arm 12, the pivot arm 10, and the electronic display 14, together, are adjustably positionable about the swivel axis 54. In addition thereto, the swivel arm 12 is rotatable about swivel axis 22, whereby the pivot arm 10 and the electronic display, together, are adjustably positionable about the swivel axis 22 independent of the adjustable positioning of the swivel arm 12. The pivot arm 10 also is pivotable about the pivot axis 46 and the pivot axis 48, whereby the pivot arm 10 and the electronic display 14, together, are adjustably positionable about the pivot axis 46 and pivot axis 48 independent of the adjustable positioning of the swivel arm 12.

[0062] Yet still, as shown in FIG. 1, the electronic display 14 is pivotable about the pivot axis 36, whereby the electronic display 14 is adjustably positionable about the pivot axis 36 independent of the adjustable positionings of the pivot arm 10. The electronic display further is pivotable about pivot axis 38, whereby the electronic display is further adjustably pivotable about the pivot axis 38 independent of the adjustable positioning of the pivot arm 10. The electronic display 14 also is rotatable about the swivel axis 30, whereby the electronic display 14 is adjustably positionable about the swivel axis 30 independent of the adjustable positionings of the pivot arm 10.

[0063] Notable characteristics of the illustrated embodiment in, for example, FIG. 2 include the fact that the swivel axes 54, 22, and 30 remain parallel to each other, and remain orthogonal to the translation axis 58, throughout all of the aforementioned adjustable positionings. Similarly, each of the pivot axes 46 and 48 and pivot axes 36 and 38 (FIG. 1) remain orthogonal to each of the swivel axes 54, 22, and 30 throughout all of the adjustable positionings. In addition thereto, it will further be noted that all of the pivot axes 46, 48, 36, and 38 remain non-orthogonal to the translation axis 58 through a range of adjustable positionings of the electronic display 14 and/or pivot arm 10. In a preferred method, the electronic display assembly is utilized to present audiovisual content to a person in a resting position. Accordingly, a preferred embodiment of an electronic display assembly is illustrated in FIG. 3 and includes the preferred embodiment of FIG. 1 combined with an apparatus 60 for receiving a person in a resting position. The apparatus broadly comprises, for example, a chair, recliner or bed and, in the field of providing a healthcare service, the apparatus preferably comprises a dental chair or operating table for supporting a patient receiving healthcare.

[0064] As will become apparent from review of FIG. 3, the electronic display 14 is suspended above, i.e., over, the apparatus 60 for convenient and unobstructed viewing by the person. Moreover, it thus will thus be appreciated that the electronic display 14 is coupled to a support such that the electronic display is adjustably positionable above the apparatus along each of three orthogonal axes, and such that the electronic display is adjustably positionable along each of these three axes independent of adjustable positioning of the electronic display along the other axes, thereby insuring a convenient and unobstructed view thereof by the person. Furthermore, in embodiments wherein the track is mounted to a wall or other support other than a ceiling, the electronic display 14 nevertheless preferably is still suspended above the apparatus 60 as shown in FIG. 3.

[0065] Aspects of the present invention include the presentation of audio and/or visual content to the person received in the apparatus 60. As used herein, such content is intended to be of broad meaning. Visual content may include graphical images of any level of detail. The graphical images can appear fixed in time on the display or can be moving or animated. The graphical images can be of live or recorded real, imaginary, or virtual world scenes such as that found in entertainment programs and informative news programs. The graphical images can include a view of a healthcare procedure in real time, can present expected results of a procedure, or can display or alternate between views before and after completion of a procedure or procedural step. Visual content also may include visual sensory stimulations as used in seeing ability tests, optometric evaluations, healthcare practices related to the eyes, psychological studies, or brain function mapping techniques. Visual content may also include navigable menus and folders such as implemented in conventional graphical user interfaces of computing systems. Internet browsing can be available with the use of the electronic display. Word processing, accounting software applications, and practice management proprietary or commercial software applications can be utilized by a patient or healthcare provider using the electronic display. The visual content may also represent the functionally operative portions of a touchscreen.

[0066] Accordingly, FIG. 3 further serves to illustrate a preferred embodiment for the wireless presentation of such content to the person while received in the apparatus 60. In particular, a send unit 62 is operative for wirelessly sending signals conveying content to be presented to the person received in the apparatus 60. The send unit may comprise, for example, a transmitter for broadcasting a wireless signal 64 to the receive unit. The transmitter can be any suitable transmitter such as a wireless router or RF transmitter, or an IR transmitter.

[0067] A receive unit comprising an antenna assembly 66 is disposed on the electronic display 14 and is operative to receive the signals for presenting of the visual content via the electronic display 14. A receive unit comprising wireless headphones 68 having antenna 70 also is worn by the person and is operative to receive the signals for presenting of the audio content via a speaker component of the headphones 68. The audio content presented by the headphones 68 may be independent of the visual content presented by the electronic display 14, or the audio content presented by the headphones 68 may accompany and be synchronized with the visual content presented by the electronic display 14, as desired. In variations of such embodiments, the electronic display 14 may include speakers and the antenna assembly 66 may receive signals for both audio content and visual content. In such variations, the electronic display 14 may include a speaker component for presenting the audio content to the person, or the electronic display 14 may include an output port such as a headphone jack for further communicating signals representing the audio content. In other variations, a speaker component may be embedded in the headrest 72 of the apparatus 60 for presenting of the audio content. A preferred embodiment of an electronic display 69 incorporating a speaker component comprising speakers 71 therein is illustrated in FIG. 15. Moreover, this preferred embodiment further includes handles 73 disposed on opposite sides of the electronic display 69 in order to facilitate the adjustable positioning by the viewer.

[0068] The send unit 62 is shown in FIG. 3 as being attached to a wall; however, the send unit 62 may be disposed anywhere so long as the receive units 66,68 are within its transmission range. Alternative locations include being secured to the support to which the track 56 is mounted.

[0069] The send unit farther may be disposed in electronic communication with said receive unit by a cable or wire connection of any suitable type for carrying signals from the send unit to the receive unit. In embodiments of the system that include such a connection, the connection is preferably constructed, arranged, and routed to connect the send and receive units through a pathway internal to the overhead structure that supports the receive unit. Such an arrangement and routing provides for aesthetic elegance in the environment of the system and, particularly in a healthcare environment, avoids cluttering of a patient care area. This well complements a variable support assembly by allowing freedom of movement of a display without dangling wires congesting the immediate area of a healthcare provider and patient. This variation is illustrated in FIG. 4, where cable 74 is shown extending between, and connecting in electronic communication, both the send unit 76 with a receive unit in the form of an input jack (not shown) of the electronic display 14, and the send unit 74 with a receive unit in the form of an amplifier embedded in the apparatus 60 and having input and output jacks 78. With additional regard to this variation, the cable leading to the electronic display 14 preferably is disposed internal to at least the swivels 52 20 and 28, whereby the cable does not inhibit the range of motion that the electronic display 14 otherwise enjoys.

[0070] With regard to another variation of the invention, the range of rotation of each swivel is limited, for example limited to less than full rotation, in order to avoid twisting of a cable internal thereto. Such a variation comprises a bearing projecting from a detent under the force of a spring to lock and arrest rotation at an extreme of an allowed range.

[0071] The send unit 76 includes multiple inputs and is capable of receiving content from a range of disparate or related sources and sending signals for the various content to the receive unit in a unitary fashion. The range of sources, within the scope of the invention here described, includes without limitation, any electronic accessory or interface that produces or relays signals that convey visual and/or audio content, including, but is not limited to: a video cassette recorder (VCR) or player; a digital video disk (DVD) recorder or player; a computer; a computerized network, router, or interface; a television signal receiver or tuner; a cable signal receiver or tuner; a satellite signal receiver or tuner; a video camera; and digital X ray equipment. Thus, some multiple inputs of the send unit 76 may include, for example, an S-video input, a cable input, a USB input, and an RCA input. The exemplary embodiment 80 of the send unit illustrated in FIG. 5 includes a patch panel with ports for VGA fifteen-pin, RCA (left audio, right audio, and video), S-video, USB, and commercial cable inputs. These are exemplary, and other types of input ports are within the scope of the invention.

[0072] In accordance with aspects of the present invention, either the electronic display 14 or the subassembly 26 connecting the electronic display 14 to the pivot arm 10 includes an electronic input member for acquiring or receiving data. In this respect, the electronic input member may include in preferred embodiments of the present invention, for example: a touchscreen of the electronic display for receiving electronic input by a person's touch; an antenna disposed on the electronic display for receiving wireless data transmissions; an electronic communications port included in the electronic display for receiving data such as, for example, a USB port, a firewire port, a serial port, a parallel port, or a PS/2 port; and a data acquisition device mounted to the electronic display or subassembly, the data acquisition device including, for example, a sensor, a camera, or a microphone. Exemplary embodiments of electronic displays including electronic input members are illustrated in FIGS. 13-14.

[0073] In accordance with aspects of the present invention, an electronic input member also may be included that is physically independent from the electronic display and subassembly. In this respect, the electronic input member may be detachably mounted to a support accessible to the person viewing the electronic display. The electronic input member may include in preferred embodiments of the present invention, for example: a conducting contact; an electromechanical switch; a mouse; a handheld device; a joystick; a keyboard; a keypad; and a wireless device such as a remote control.

[0074] In certain preferred embodiments that include an electronic input member for receiving or acquiring data, a computer or other electronic circuitry preferably is provided in electronic communication with the electronic input member for processing data received or acquired from the electronic input member. In such embodiments, the computer may store and analyze the data from the electronic input member. Results of the analysis then may be presented via the electronic display. If the electronic input member is a camera, video acquired by the camera may be captured and then displayed on the electronic display. In other such embodiments, the computer may simply manage presentation of video on the electronic display, and the data from the electronic input member may represents instructions for managing the presentation of the video on the electronic display. The computer further may be coupled to the carriage for movement therewith, and may even be disposed within a housing of the electronic display. Alternatively, the computer may be remotely located to the electronic display and, thus, stationary with respect to movement of the carriage.

[0075] With reference again to FIG. 5, an electronic input member comprising a wireless remote control 82 is shown. The remote control 82 preferably communicates wirelessly with the send unit 80 (i.e., the computer or other electronic circuitry in this illustration), for controlling the presentation of the audio and/or video content. Control of the content may include, for example, selecting for presentation a movie, a television station a cable station, a music video, an educational video, a cartoon. Such control may further include, for example, navigating the Internet, including reading email and composing email, especially where the electronic input member includes an arrangement of alphanumeric keys. In this case, a keyed input device may be provided. In any event, the person viewing the electronic display (and/or a healthcare provider in the context of providing healthcare to a patient viewing the electronic display) preferably has some control over the content presented by the electronic display.

[0076] In a particular preferred embodiment, the electronic input member for receiving input regarding controlling presentation of the content presented by the electronic display communicates directly with a receive unit which, in turn, is operative, in response to the input received by the electronic input member, to send signals to the send unit for controlling presentation of visual content by the electronic display. In this regard, the send unit then is operative for receiving the signals for controlling presentation of visual content from the receive unit and responding accordingly. This reverse communications system is useful when the send unit is disposed remote from, and possibly out of range to, the electronic input member.

[0077] In accordance with aspects of the present invention, particular content to be presented by the electronic display is actually selected by use of an electronic input member and then delivered to the electronic display in response to such selection. Furthermore, the content preferably is selected by each patient from a plurality of available selections and delivered on demand at the time of the selection. This is particularly useful in a healthcare environment, wherein a plurality of patients may be provided from a central distribution source with particular content upon demand.

[0078] The contemporaneous delivery of content is schematically illustrated in FIG. 6, wherein the audio and/or video content is centrally stored at 84 and then delivered to each of displays 86,88,90. The central distribution system preferably includes at least one data storage device for digitally storing the available content selections. The data storage device may include, for example, a computer readable medium, computer memory, or one or more optical discs. Each of the displays represents an electronic display assembly in accordance with the present invention.

[0079] As shown in FIG. 6, the content is centrally stored on premises of the healthcare facility having the multiple electronic displays 86,88,90. Alternatively, as shown in FIG. 7, the content is centrally stored at a central distribution system 92 located off premises with respect to the multiple healthcare facilities 94,96, each of which utilizes the electronic display assemblies 98 of the present invention in providing healthcare service. Communications of content from the central distribution system to each healthcare facility may occur via the Internet. Moreover, the content may be communicated in a digital format as a real time signal or data flow, or as a video file or a video file portion such as, for example, a program clock reference (PCR) stamped moving picture experts group (MPEG) file.

[0080] In accordance with a particular aspect of the present invention relating to the central distribution system, a third-party party preferably is responsible for providing content to each of the healthcare facilities for presentation on the electronic display assemblies of the present invention. Moreover, this third-party preferably is not in the business of providing healthcare services but, instead, is a service provider to the healthcare facilities. As such, the content preferably is provided by the third-party under a subscription contract or on a pay-per-view basis.

[0081] In accordance with other aspects of the present invention, and again with particular reference to the provision of healthcare service, an audio or audiovisual communications system preferably is provided for use between a patient receiving a healthcare service and a healthcare provider. The audio communications system includes a speaker component for providing auditory content to the patient while receiving the healthcare service, an audio component in communication with the speaker component for providing the auditory content to the speaker component, and an input controller accessible to the healthcare provider for controlling the provision of the auditory content to the patient.

[0082] The speaker component may comprises, for example, headphones or earphones for wearing by the patient. The speaker component alternatively may comprise, for example, a speaker coupled to, or embedded in, the apparatus. If embedded in the apparatus, the speaker preferably is embedded in a headrest of the apparatus in order to be in close proximity to a patient's head. The audio component preferably communicates wirelessly with the speaker component, in which case the speaker component preferably includes a wireless signal receiver for receiving signals conveying the auditory content. In this regard, the wireless signal receiver may include a radio-frequency (RF) or infrared (IR) signal receiver.

[0083] Conveniently, the input controller comprises a foot actuated switch or pedal, whereby the healthcare provider may varying the volume of, or altogether mute, the auditory content provided to the patient while receiving the healthcare service in order that the patient will hear the healthcare provider speaking. In this respect, the input controller essentially comprises a volume control device. Alternatively, a microphone component may be provided by which the healthcare provider speaks to the patient through the speaker component. In doing so, the microphone component preferably communicates directly with the audio component for conveying the voice of the healthcare provider to the patient, or the microphone component communicates directly with the speaker component for conveying the voice of the healthcare provider to the patient. Furthermore, the auditory content otherwise being provided to the patient preferably is lowered, or altogether muted, when the microphone is activated for recording the voice of the healthcare provider. In this context, the microphone preferably is activated using an input controller of the healthcare provider which, again, preferably comprises a foot actuated switch or pedal. Furthermore in this context, the input controller is seen as being, again, a volume control device.

[0084] The input controller of the healthcare provider may include the ability to select and manage the content provided to the patient. Alternatively, or in addition thereto, the patient preferably is provided an input controller for controlling, by the patient, the provision of the auditory content. This may further include the ability to select the audio or audiovisual content to be presented on the electronic display, in which case the input controller also comprises an aforementioned electronic input member.

[0085] Similar to the aforementioned central distribution system of FIGS. 6 and 7, in preferred embodiments the audio communications system includes a storage component wherein a plurality of auditory content selections are stored. Furthermore, the storage component is disposed in electronic communication with the audio component for providing, by the audio component, any one of the auditory content selections to the speaker component. The storage component may include, for example, a digital jukebox and/or a DVD jukebox. The storage component also may be a computer readable medium, in which case the audio component preferably comprises a computer. Moreover, the storage component may be stored on premises or off premises, either by the healthcare facility entity or a third-party, similar to the aforementioned video delivery system discussed above in connection with FIG. 6-7. In any event, in such preferred arrangements, the patient using the input controller may (1) conveniently select that auditory content desired while receiving healthcare, and (2) conveniently adjust the volume of the auditory content provided.

[0086] Use of the electronic display assembly of FIGS. 1-4 in a healthcare environment is illustrated in FIG. 8. In this regard, the healthcare being provided to the patient comprises dental healthcare.
