[0044] The dates of the foregoing publications may correspond to any one of priority dates, filing dates, publication dates and issue dates. Listing of the above patents and patent applications in this background section is not, and shall not be construed as, an admission by the applicants or their counsel that one or more publications shown in the above list constitute prior art in respect of the applicant's various inventions. All printed publications, patents and patent applications referenced above or otherwise herein are hereby incorporated by referenced herein, each in its respective entirety.

[0045] Portable hydration systems adapted to be worn, carried or otherwise made available to a user often comprise a bladder disposed in a backpack, a hydration bite valve, and a hydration hose extending between the bite valve and the bladder so that the user can suck water or other drinkable fluid from the bladder through the hydration hose and the hydration bite valve. Such hydration systems are typically configured so they may be employed in a substantially hands-free manner, and are often portable.

[0046] Motorcycling and motorcycle racing, bicycling and bicycle racing, and auto racing are activities where drivers or riders can become dehydrated, especially in long or endurance races or events that can last many hours. In fast moving races or events, it is imperative that the driver or rider keep his or her hands on the vehicle or bike controls at all times.

[0047] In such races and events, however, racers or participants routinely wear helmets for head protection. Routing a hydration hose through, around or under a helmet, and arranging a hydration bite valve in a position that remains comfortable and usable over a sustained period of time for a helmet-wearing user, can be difficult or impractical. Adjustment or tinkering with a hydration hose or bite valve during such events is often not an option. As a result, conventional portable hydration systems employing bite valves, hydration hoses and bladders are not well suited for use in such races or events.

[0048] To overcome the problems associated with conventional portable hydration systems employing hydration hoses and bite valves, a few electrical pump fluid delivery systems have been developed which are capable of delivering squirts of fluid to the mouth of a user over a distance of a few inches, where the distal end of a hydration hose is positioned near the mouth of the user, and where the user typically actuates the electrical pump using a hard-wired switch. However, some of these electrical pump fluid delivery systems require as much or more manual interaction by the user as conventional hydration systems. In addition, including electrical and electronic hardware in a hydration system to permit enhanced control of fluid delivery can be cumbersome and heavy to implement, and lead to reliability and cost problems, such as relays, wires or switches that are prone to failure.

[0049] What is needed is a portable hydration system that can be used with ease, that is comfortable and reliable, and that does not require regular or excessive adjustment to operate properly.

[0055] Further embodiments are disclosed herein or will become apparent to those skilled in the art after having read and understood the specification and drawings hereof.

[0064] The drawings are not necessarily to scale. Like numbers refer to like parts or steps throughout the drawings.

[0065] Described herein are various embodiments of systems, devices, components and methods for providing hydration to a user from a fluid reservoir or bladder, where the fluid is provided on demand by the user activating and controlling a user interface that communicates wirelessly with a control assembly operably connected to a pump and the fluid reservoir. The control assembly is operably and programmably connected to the fluid pump, which in turn is connected to the fluid reservoir to pump fluid therefrom to a mouth of a user upon demand thereby. Other embodiments encompassing use of a similar system for portable, stationary, bilge, sump pump, and handicapped person applications are also described and contemplated.

[0066] Referring now to FIG. 1, there is shown one embodiment of a portable wirelessly-controlled and activated hydration system 10. In the embodiment shown in FIG. 1, system 10 comprises first control system 100, second control system 200, fluid pump 300, fluid reservoir or hydration bladder 400, and helmet 500. In many applications, fluid reservoir or hydration bladder 400 is contained or held in a backpack, waist-pack or similar device for carrying by a user (not shown in the Figures). Note that in some embodiments, not all the foregoing elements or components are required or need be present.

[0067] In the embodiment shown in FIG. 1, first control system 100 comprises first control assembly 102, enclosure 103 for first control assembly 102, first LEDs/visual indicators 110/111, first power supply 114, first power supply positive and negative wires and connections 116/118, and first control assembly pairing button 122. First control assembly 102 is operably connected to and electrically powered by power supply 114, which may comprise one or more batteries, or any other suitable source of portable or stationary electrical energy, such as DC or AC electrical power.

[0068] First control system 100 is operably connected to fluid pump 300, which in turn is operably connected to hydration or fluid reservoir or balder 400 and helmet 500 by means of hydration hoses 404 and 410. Hydration hose 404 is connected to input port 302 of pump 300, and comprises first and second ends 406 and 408, and has optional quick-connect mechanism 402 attached to end 406 for quick connection and release from bladder 400. Hydration hose 410 comprises first end 412, second end 414, and nozzle/mouthpiece 418, and is connected to output port 304 of pump 300, and provides fluid from bladder 400 pumped by pump 300 to a user wearing helmet 500. Hose 410 may be routed through helmet cuffs 502 mounted inside or outside helmet 500, and may also feature an optional second quick-connect and release mechanism 416 to permit a user wearing helmet 500 to quickly attach to and release from the other components of hydration system 10.

[0069] Non-limiting examples of pumps 300 suitable for use in connection with at least some of the embodiments shown in FIGS. 1-7(b) hereof are pump model numbers AD10B, AD103, AD400, manufactured by Shenzhen Giant Electric Tech Inc. of the People's Republic of China. These pumps are all centrifugal, operate at 12 Volts DC, are single stage, have ABS plastic housings, provide maximum flow rates around 300 to 400 liters/hour, weigh around 60-70 grams, and have noise levels less than around 40 dB. Note that least some of the foregoing Shenzhen Giant Electric Tech Inc. pumps are not suitable for applications where pulse width modulation (PWM) control schemes are employed by systems 100 or 200. In PWM applications, other types of pumps 300 can be used. Still other types of suitable pumps are also contemplated, such as those which operate under AC power.

[0070] In the embodiment shown in FIG. 1, second control system 200 comprises user interface 212, which in turn comprises second control assembly 202, enclosure 203 for second control assembly 202, second LEDs/visual indicators 210/211, second power supply 214, second power supply positive and negative wires and connections 216/218, and second control assembly pairing button 222. Second control assembly 202 is operably connected to and electrically powered by power source 214, which may comprise one or more batteries, or any other suitable source of portable or stationary electrical energy, such as DC or AC electrical power. Switch or control 215 permits a user to activate or deactivate wirelessly, as the case may be, or to otherwise control operation or programming of, first control system 100 and/or pump 300. Note that the embodiment of second control system 200 shown in FIG. 1 differs from the embodiment of second control system 200 shown in FIG. 3 in the respect that second control system 200 shown in FIG. 1 has user interface 212 and switch 215 incorporated into second control assembly 202 and enclosure 203. In second control system 200 shown in FIG. 3, however, user interface 212 and switch 215 are located separate from second control assembly 202 (but remain operably connected thereto).

[0071] In one embodiment, user interface 212 is attached to a handlebar or other type or component of a vehicle that is being operated by the user by means of user interface attachment mechanism 213, which may comprise bracket(s), one or more Velcro straps, an adhesive, bolts and nuts, or any other suitable means of attaching user interface 212 to the vehicle that is being operated by the user or the vehicle component. In another embodiment, where for example the user is a runner or skier, user interface 212 can be configured to be hand-held, or to be attached or incorporated into, by way of illustrative non-limiting example, the user's belt, wrist, glove, mitten, finger ring, clothing, sleeve, ski pole, or other portable or wearable device or clothing article.

[0072] FIGS. 2 and 3 show further details of the embodiments of first control system 100 and second control system 200 shown in FIG. 1, respectively, and various components associated therewith.

[0073] In FIG. 2, a conventional athletic activity hydration bladder 400 is shown connected to quick-connect mechanism 402. Such a quick-connect mechanism 402 can be employed, but other means of connecting to bladders or reservoirs 400 are also contemplated such as permanent or semi-permanent hydration hose connection mechanisms. In addition, types of fluid reservoirs 400 other than hydration bladders are also contemplated, such as portable or fixed or stationary fluid refillable bottles and containers.

[0074] In FIG. 2, and for illustrative purposes, first control system 100 is represented and shown without protective enclosure 103 surrounding first control assembly 102. First control assembly printed circuit board 120 is shown with various electronic and electrical components mounted thereon, such as first wireless transceiver 104, first computing device 106 and first processor 108, first LEDs/visual indicators 110/111, first voltage regulator 107, first potentiometer 109, and first pairing button, switch or control 122. First power supply 114 is operably connected to first control assembly printed circuit board 120 by wires or electrical conductors 116 and 118, while pump 300 is operably connected to first control assembly printed circuit board 120 by wires or electrical conductors 124 and 126. Pump inlet port 302 of pump 300 is operably connected by hose 404 to hydration balder or reservoir 400. Hydration hose 410 connects outlet port 304 of pump 300 to nozzle or mouthpiece 418, which is configured to be positioned near a user's mouth to receive fluid from reservoir 400 as pump 300 conveys fluid therefrom to the distal end 414 of hose 410. (As shown in FIG. 1, however, hose 410 may include an additional quick-connect mechanism 416, and distal end 414 may be attached to a helmet 500.) Nozzle or mouthpiece 418 may also be configured to focus a stream of water to the mouth of a user.

[0075] In FIG. 2, first control assembly includes printed circuit board 120 with the various electronic components listed above, including first computing device 106, which can comprise, by way of example, a processor, microprocessor, controller or CPU 108 comprising RAM and ROM memory, busses, and other components included in or connected to computer processors such as storage devices and so on. First computing device/first processor 106/108 is also operably connected to first wireless transceiver 104, which is configured to communicate wirelessly with second wireless transceiver 204 of second control system 200. Pairing button 122 can be employed for a user to change communication channels employed by wireless transceiver 104, more about which is said below. Potentiometer 109 can be employed to adjust or change the pump flow duration of pump 300. Voltage regulator 107 allows first control assembly 102 to operate across a range of different or varying input voltages delivered by power supply 114. LEDs/visual indictors 110 and 111 can be configured to indicate to a user power status and connection status/signal reception between control system 100 and control system 200. As noted above, power supply 114 may comprise a battery pack, or may comprise a vehicle or any other suitable type of AC or DC power. Pump 300, first control assembly 102, and power supply 114 may all or in any combination be contained in a protective enclosure.

[0076] In FIG. 3, and for illustrative purposes, second control system 200 is represented and shown without protective enclosure 203 surrounding second control assembly 202. Second control assembly printed circuit board 220 is shown with various electronic and electrical components mounted thereon, such as second wireless transceiver 204, second computing device 206 and second processor 208, second LEDs/visual indicators 210/211, second voltage regulator 207, second potentiometer 209, second LEDs/visual indicators 210/211, and second pairing button, switch or control 222. Second power supply 214 is operably connected to second control assembly printed circuit board 220 by wires or electrical conductors 216 and 218, while user interface 212 is operably connected to second control assembly printed circuit board 220 by wires or electrical conductors 224 and 226 (although wireless connection between user interface 212 and second control system/second control assembly 202 is also contemplated).

[0077] Second control assembly 102 includes second printed circuit board 220 with the various electronic components listed above, including second computing device 206, which can comprise, by way of example, a processor, microprocessor, controller or CPU 208 comprising RAM and ROM memory, busses, and other components typically included in or connected to computer processors such as storage devices and so on. Second computing device/second processor 206/208 is also operably connected to second wireless transceiver 204, which is configured to communicate wirelessly with first wireless transceiver 104 of first control system 100, and optionally with user interface 212 as described above. Pairing button 222 can be employed for a user to change communication channels employed by wireless transceiver 204 and/or wireless transceiver 104. Voltage regulator 207 allows second control assembly 202 to operate across a range of different or varying input voltages delivered by power supply 214. LEDs/visual indicators 210 and 211 can be configured to indicate to a user power status and connection status/signal reception between second control system 200 and first control system 100. As noted above, power supply 214 may comprise a battery pack, or may comprise a vehicle-mounted power supply, or any other suitable source of AC or DC power. System 200 and power supply 214 may all or in any combination be contained in a protective enclosure.

[0078] Continuing to refer to FIG. 3, user interface 212 is shown attached to handlebar 600 of a motorcycle or bicycle by means of attachment mechanism 213. User interface 212 is mounted and positioned to provide easy access to a finger or hand of a user so that switch or control 215 may be activated or deactivated easily and essentially hands-free by a user while the bicycle or motorcycle is being operated. User interface 212 may also be mounted on steering wheel of a vehicle or any other portion of a vehicle being piloted by a user. In FIG. 3, and to reduce system costs and expense, the hardware mounted on second control assembly printed circuit board 220 may be identical to that of first control assembly printed circuit board 120. In one embodiment, activation of button/switch 215 by the user causes second control assembly 202 to send a series of repeating commands through wireless transceiver 204 to first control assembly 102 to which it is paired. Second control assembly printed circuit board may be enclosed in a protective enclosure 203 (not shown in FIG. 3, but shown in FIG. 1).

[0079] The components of system 10 shown in FIGS. 1, 2 and 3 are configured to operate together so that when a user presses button, switch or control 215 second control assembly 202 sends a repeating series of “pump-on” commands to pump 300 via second wireless transceiver 204 to first wireless transceiver 104 and first control assembly 102 to which it has been paired. When first control assembly 102 receives such “pump-on” commands, pump 300 is actuated by first computing system/first processor 106/108 to pump fluid from reservoir 400 to nozzle or mouthpiece 418. In one embodiment, pump 300 is electrically powered by first power supply 114 via electrical conductors 116/118 and 124/126, and via voltage regulator 107.

[0080] In some embodiments, pulse width modulation (PWM) is employed by first computing system/first processor 106/108 to finely control the delivery and timing of electrical current to pump 300 using programmable and/or stored software settings. In some embodiments, stored or programmed PWM settings can be selected by a user according to the flow rate, pressure, fluid volume, and duration of fluid delivery that the user desires. For example, first processor 108 may be configured by the user to deliver fluid for a predetermined and selected period of time after switch 215 has been pressed by the user, with fluid delivery being terminated after the predetermined period of time has passed. Alternatively, first processor 108 may be configured by the user to deliver fluid continuously while button or switch 215 is being pressed, and to stop delivering fluid after button or switch 215 has been released. The user may also change the pressure or rate at which fluid is being delivered by system 10. Other types of changes or controls regarding fluid delivery are also contemplated to be adjustable by a user, such as manual hardware adjustment by a user of potentiometer 109 to change fluid flow rate. In some embodiments where PWM is used to control the operation of pump 300, it is better to vary the current delivered to pump 300 rather than the voltage.

[0081] Referring now to FIG. 4, there is shown a block diagram of one embodiment of hydration system 10. The various components of system 10 described above in connection with FIGS. 1, 2 and 3 are shown in FIG. 4. Second control system 200 communicates with first control system 100, and/or vice versa, via wireless signals 230. The user activates and/or deactivates the operation of pump 300 via user interface 212, and may pair control system 200 to control system 100 via second pairing button/device 222 of second control assembly 202. In some embodiments, both pairing buttons 122 and 222 in systems 100 and 200 are pressed to initiate, effect and complete the linking procedure.

[0082] In one embodiment, during the linking procedure a separate trigger button of second control assembly 202 is pressed to initiate selection of a random and unique communication code by processor 208, which is then transmitted to first control assembly 102 for storage in memory and subsequent retrieval therefrom for cross-checking with and confirmation of the same code subsequently received in a wireless transmission of signals from second assembly 200, more about which is said below. The generated unique communication code prevents unwanted interference or cross-talk with other nearby wireless communication devices or systems, and enhances the reliability, strength and stability of wireless communication transmission and reception between systems 100 and 200, and assemblies 102 and 202 corresponding thereto. The aforementioned trigger button may be button or switch 215, but may also be a different button (not shown in the Figures).

[0083] In one embodiment, when both control systems 100 and 200 are placed into link mode by pressing pairing buttons 122 and 222, one of the processors 108/208 in the two control assemblies is programmed to randomly select from a defined array of 5-bit addresses a unique 5-bit address. The processor also randomly selects from among a defined array of 6 wireless frequencies in the 2.4 GHz spectrum a single communication frequency to associate with the unique address that has been selected. The processor then pairs the selected unique 5-bit address with the selected wireless communication channel and stores this unique combination of a selected 5-bit address and a selected single communication frequency in memory as a unique communication code. Note that the combination of an array of 5-bit addresses and 6 randomly selectable communication frequencies yields (6×10)¹² possible address/communication frequency combinations (6,000,000,000,000, or 6 trillion combinations). For all intents and purposes, therefore, the selected random combination or communication code is unique, and in actual practice will never be repeated or used by a different nearby wireless communication system. The second control assembly transmits that combination or code to the first control assembly when the actuator switch/button/trigger is pressed as the final step in the pairing process. The first control assembly receives and stores the combination and until relinked, will only accept instructions from a device transmitting with that exact same combination of a 5-bit address and 2.4 GHz communication frequency. In some embodiments, an opposite pairing sequence is employed, where a trigger button is located on first control assembly 102, and combination of a selected random address and a selected communication frequency is sent to second control assembly 202 from first assembly 102.

[0084] LEDs 110/111 and 210/211 may be used to visually indicate whether pairing has occurred successfully, whether power supply levels are adequate, the flow rate a user has selected, and so on.

[0085] In some embodiments, any one or more of first computing system 106 and second computing system 206 may comprise a CPU, controller, microcontroller, processor, microprocessor or any other suitable processing device 108 or 208, and may further include system memory, and a system bus that operably connects various system components, including the system memory, to processors 106 and/or 206. First or second computing devices 106 and 206 further comprise at least first and second non-transitory computer readable media configured to store first and second instructions executable by at least first processor 108 and second processor 208, respectively. Multiple processors and other multi-processor architectures also can be used to form first or second computing system 106 and/or 206. In many embodiments, a system bus is utilized, and may comprise any of several types of suitable bus architectures, including a memory bus or memory controller, a peripheral bus, or a local bus. System memory can include read only memory (ROM) and random access memory (RAM). A basic input/output system (BIOS) can be stored in ROM and contain basic routines configured to transfer information and/or data among the various elements within computing systems 106 and/or 206.

[0086] Computing systems 106 and/or 206 can include storage devices such as flash memory, RAM, ROM, and the like. Such storage devices may be configured to provide temporary or nonvolatile storage of data, data structures, and computer-executable instructions for computing systems 106 and/or 206. Any such storage media may contain computer-executable instructions for implementing one or more parts of the devices and methods described and disclosed herein.

[0087] A number of program modules may be stored in storage devices and RAM or ROM, including an operating system, one or more application programs, other program modules, and program data. The application programs and program data can include functions and methods programmed to acquire, process and display data from one or more sensors or input devices.

[0088] FIG. 5 shows another embodiment of a block diagram of hydration system 10 configured for multiple users of the same second control system 200/user interface 212. In FIG. 5, Users 1 through N are illustrated, each having his or her own first control system 100, first control assembly 102, and associated pump 300, hydration bladder 400, and helmet 500. Each user individually wirelessly and uniquely pairs his or her own first system 100 with second system 200 (more about which is said below). Second control system 200 is mounted in or attached to vehicle 600. Processors 108 of each first control system 100 can be configured to provide random pairing of 6 channels with 5 byte addresses thereby to provide 6×10 to the 12th pairing options to second control system 200. As a result, user interface 212 of system 200 can be paired uniquely to many riders or drivers with essentially no possibility of inadvertent or unwanted crosstalk or interference from other riders using different wireless systems and communication channels. As a result, multiple riders or drivers can serially use the same user interface installed in or on a vehicle such as an automobile, motorcycle, or bicycle, while each rider or driver uses his or her own hydration backpack and systems 100, 300 and 400. Alternatively, system 10 can be configured so that fluid reservoir 400 is a large fluid container mounted in or on vehicle 600. Multiple serial users of vehicle 600 users sequentially swap out their quick-connection mechanisms 402 to fluid reservoir 400 and or/pumps 300 when they take over operation of vehicle 600. Quick-connection mechanisms to connect pump 300 to first system 100 are thus also contemplated. Further details regarding pairing are also provided below.

[0089] FIG. 6 shows one embodiment of a flow diagram according to one method 700 of pairing multiple control systems 100 to a single control system 200, as described above. At Step 701, pairing of first system 100 with second system 200 is initiated. At Step 702, successful pairing of first system 100 with second system 200 is confirmed. At Step 703, pairing of second system 100 with first system 200 is initiated. At Step 704, successful pairing of second system 100 with first system 200 is confirmed. At Step 705, Steps 701 and 702, and/or Steps 703 and 704, are repeated for additional users and systems 100 and/or 200. Other combinations, permutations, and/or modifications of steps 701-705 in method 700, and of the order in which steps 701-705 are carried out, are also contemplated.

[0161] In FIGS. 7(a) and 7(b), the below descriptions and details of the various electrical and electronic components disclosed in the embodiment illustrated therein are applied thereto.

• [0162] Batt+=power positive terminal connection
• [0163] Batt−=Power negative terminal connection
• [0164] D1—Diode 1 is a Schottky barrier diode which provides low on voltage and fast recovery times and low junction capacitance to provide reverse polarity protection in case the power source is connected in reverse.
• [0165] D2—Diode 2 is a surface mount transient voltage suppressor that shunts to ground in cases of short high voltage pulses to protect the other circuitry. This diode starts conducting at about 17.8 v and clamps (conducts all electricity) when 23.6 volts is reached.
• [0166] R1—Resistor 1 is part of the circuitry to control voltages over 16 v and acts as a voltage divider to reduce power dissipated in U1.
• [0167] C1 and C2—Decoupling capacitors 1 and 2 when in parallel suppress high frequency noise (e.g., AC ripple) in the circuit as well as provide input stabilization for U1.
• [0168] C1 and R1—Together form a low-pass filter to further reduce electrical noise from getting into and out of the digital system.
• [0169] U1—MIC2951 micro power voltage regulator with a fixed 3.3 v output capable of surviving surges up to 60 v (e.g. vehicle load dumps). Programmable to output power from 1.24V to 29V and survive surges to 60V (load dump),
• [0170] C3—Capacitor 3 is an output bypass capacitor for U1 to smooth power input to system if the voltage regulator experiences dropout.
• [0171] D3—Power-on LED (green) which indicates power is supplied to system.
• [0172] R2—Resistor 2 to limit the current to the LED and to prevent it from burning out from small changes in voltage.

• [0173] CON3 for nRFL2401+—2.4 GHz radio transceiver that provides transmitter and receiver capabilities to the system.

• [0174] External Button—button or user-operated input device that enables operation on demand
• [0175] R5—Resistor 5 provides protection for ESD (Electrostatic Discharge) events from the button.
• [0176] D6—BAV99—Dual surface mount switching diode provides protection for ESD events from the button.
• [0177] R6—Resistor 6 is a pull-up resistor that keeps the FLOWB_N signal high (off) until the button is pressed. It is used instead of an internal micro-controller input for additional noise immunity.

• [0183] Q1—Enhancement mode MOSFET transistor (Trench MOSFET) provides low on-resistance and fast switching speed to switch power on and off to the pump.
• [0184] R7—Potentiometer used to define flow duration from button press. At lowest setting the pump operates in “momentary mode” and pump stays on as long as “External Button” is pressed or engaged. As the potentiometer is turned clockwise past the half-way point, the pump duration increases, for example to 1 second, 2 seconds, 3 seconds, 4 seconds, and/or 5 seconds. This means that if the potentiometer is set at value “3”, when the user presses the button or engages the “External Button” for any time at all, that the pump will operate for 3 seconds only and then turns off and waits for a new button press.
• [0185] RATE—Rate is the input to the microprocessor of the potentiometer value selected by the user.

Diagnostics are revealed via a defined blink sequence for either linking issue.
• [0191] R3—Resistor 3 to limit the current to the LED and to prevent it from burning out from small changes in voltage.

[0192] LINKL_N—input to D4 from microprocessor to power on and power off the D4 LED. Potentiometer

• [0193] J1—an optional solder-jumper that can be used to inform the firmware running on the micro-controller that the device is configured as a transmitter or receiver.
  The “Load for Pump Configuration” and “Load for Transmitter Configuration” sections identify the position-specific set of components to be loaded if separate printed circuit boards are built for each function (e.g., to reduce cost). The schematic of FIG. 5 indicates what would need to be installed and/or removed for differentiation of systems 100 and 2000.

• [0194] U2—ATMega328P_TQFP
  The remaining components do the following:
• [0195] C6—provides an AC couple from a signal on the programming header to reset the micro-controller at the start of a programming operation.
• [0196] R4—a pull-up resistor on the micro-controller reset line.
• [0197] C4—bypass capacitors for the micro-controller voltage supply.
• [0198] C5—filter capacitor for the micro-controller internal ADC (analog-to-digital converter) voltage reference (used to measure the potentiometer voltage).
• [0199] Y1—8 MHz resonator to provide the clock signal for the micro-controller.
• [0200] R8—pull-up resistor on the data line from the NRF24L01 module to the micro-controller.

[0201] Further to the schematic block diagram shown in FIGS. 7(a) and 7(b), and according to one embodiment, provided below in Table 1 are examples of pseudo-code software modules that may be loaded into the memory of, and executable by, first processor 108 and/or second processor 208.

[0202] According to some embodiments, provided below are further descriptions of how LEDs and pairing can be configured and executed in systems 100 and 200. Note that in one embodiment a lit green LED indicates that power is on. The green LED should be on when assembly 102 or 202 has electrical power provided thereto. Also pairing button 122 and/or 222 should be pressed to set a device to Link Mode (pairing mode). The pairing button should be pressed again to resume normal operation and not to pair or to unpair.

[0203] Link Procedures

• • [0204] 1. Press pairing button on both devices to initiate the linking process. Red LED turns on indicating Link Mode.
  • [0205] 2. Press and release switch or button 215 of user interface 212 of the second control system 200 (the transmitter). This finalizes the linking process
  • [0206] 3. Red LEDs should be turned off on both systems 100 and 20 indicating successful pairing. Now each system has a custom RF Channel/Address combination.
  • [0207] 4. If the Red LED on the transmitter blinks a pattern and the Red LED on the receiver shines steady and does not go out then the link failed. Try again.
  • [0208] 5. The transmitter will not change its configuration unless it gets an acknowledgement that the receiver also successfully received the link information.
    • [0209] Link second, third or more pump modules associated with the first control assembly 102 to the same user interface button of a second control assembly 202:
      • [0210] A. Press link button on transmitter and new receiver (pump).
      • [0211] B. Red LED is lit.
      • [0212] C. Press and hold down button for more than 2 seconds (perhaps say 3 seconds) and release.
      • [0213] D. Both LEDs should go out.
      • [0214] E. Now when the transmitter pump button is pushed then both pumps should run.

[0215] Red LED has Multi-Use Functionality

• • [0216] 1. Solid red LED on indicates Link Mode
  • [0217] 2. Repeating 2 blinks followed by a short pause indicates that the microcontroller could not successfully communicate with its own radio module.
  • [0218] 2. Repeating 3 blinks followed by a short pause indicates that the transmitter could not verify the receiver was properly linked.
  • [0219] 3. Repeating 4 blinks followed by a short pause indicates that the transmitter was unsuccessful in sending a pump command to the receiver. This usually occurs when the receiver is turned off or not properly linked, and can also happen if there is too much distance or interference between the transmitter and receiver.

[0220] LED and Repeating Packets

• • [0221] 1. While the pump button is pressed, the transmitter sends a “Pump On” packet every 50 mSec. The receiver starts the pump for a 200 msec period. This way it can miss an occasional “Pump On” packet while the button is pressed.
  • [0222] 2. When the pump button is released, the transmitter sends a “Pump Off” packet and the receiver immediately shuts the pump off.
  • [0223] 3. The 200 msec window ensures the pump will turn off quickly even if the “Pump Off” packet is lost.
  • [0224] 4. The transmitter actually will attempt to send each packet up to 6 times before giving up for that packet and starting the 4 blink indication.
  • [0225] 5. The next successfully transmitted packets stops the LED from blinking.

[0226] Burst Duration

• • [0227] 1. The Potentiometer provides different pump durations from a single button press and is adjustable in the second control assembly.

[0228] Sleep Mode

• • [0229] 1. The modules while in normal operation mode take between 20-30 mA while idling.
  • [0230] 2. In sleep mode, current draw is reduced.
  • [0231] 3. The transmitter module is awakened by a button press.
  • [0232] 4. The transmitter wakes the pump module.
  • [0233] 5. Either module can be woken by recycling power.

[0234] Diagnostic Code

• • [0235] 1. There is a diagnostic function included in the code that outputs various diagnostic messages to the serial port on an Arduino board/microcontroller.
  • [0236] 2. If a computer is attached via the FTDI interface, the diagnostic messages can be viewed.
  • [0237] 3. Messages may be used to diagnose manufacturing problems, faulty units, and/or damaged units.

[0238] In some embodiments, first and second control assemblies 102 and 202 are housed in water resistant or waterproof enclosures 103 and 203, and wireless transceivers 104 and 204 operate at 2.4 GHz. Other wireless frequencies are of course contemplated. As described above, processors 108 and 208 can be configured to provide random pairing of 6 channels with 5 byte addresses thereby to provide 6×10 to the 12th pairing options. As a result, one button (on a bike or car, for example) can be paired uniquely to many riders or drivers with essentially no possibility of inadvertent or unwanted crosstalk or interference from other riders using different wireless systems and communication channels.

[0239] In the various embodiments, pump 300 of system 10 can be configured to be software driven as opposed to relay-driven; advantageously, no power relay is required to drive and control pump 300, which can be driven and controlled directly under software control by first control assembly 102, first computing system 106, and first processor 108. In some embodiments, bi-directional communication between transmitters and receivers is enabled, which permits real-time operational status to be provided, such as whether or not systems 100 and 200 have been paired, signal(s) have been transmitted and/or received successfully, signal(s) have been lost, no receiver is in range, battery power status, whether software has assigned a module a role (e.g., ‘transmitter’ role assigned to module if a button or other device is connected to the transmitter position on printed circuit board (PCB) 120 or 220; ‘receiver’ role assigned to the module if a pump or other device is connected to the receiver position on the PCB). Software can be configured to dictate the function of a module or system based on connections to the PCB in the transmitter and/or receiver positions. Software can also be configured to assign a ‘transmitter’ and/or ‘receiver’ role to a single module if a button/device is connected to transmitter position on the PCB and if a pump/device is connected to the receiver position on the same PCB.

[0240] In addition, modules or systems 100 and 200 may be paired to one or more modules or systems to provide:

• • [0241] User initiated pairing of one transmitter to one receiver
  • [0242] User initiated pairing of one transmitter to many receivers
  • [0243] User initiated pairing of many transmitters to one receiver
  • [0244] User-selectable pump operation modes are also possible, such as
    • [0245] Momentary
    • [0246] 3 second burst
    • [0247] 5 second burst
    • [0248] user-defined burst length

[0249] Note that in some embodiments of system 10 “transmitters” and “receivers” are interchangeable in systems 100 and 200 seeing as in some embodiments wireless transceivers 104 and 204 may be employed in both of systems 100 and 200, which adds considerably to the flexibility and range of configurability of hydration system 10. In other embodiments, a transmitter chip is used in one of systems 100 and 200, and a receiver chip is used in the other of systems 100 and 200.

[0250] Power management of system 10 can be configured to provide any one or more of the following:

• • [0251] Automatic power into low power mode after period of no use
  • [0252] Automatic power off after longer period of no use
  • [0253] User-initiated wake-up from low power and power-off mode

[0254] In terms of signal redundancy, transmission and reception, the following provisions can be made:

• • [0255] Transmission of repeating “pump-on” packets for duration of button press or for duration of user-selected operation mode.
  • [0256] Transmission of pump-off command when button press is over or at end of user-selected operation mode.
  • [0257] Receiver enters listening mode after reception of first pump-on packet. Note that once powered on systems 100 and 200 are both always in listening mode unless they are transmitting, and remain so until powered off.
  • [0258] Receiver initiated repeating listening commands until pump-off command is received or missed packet threshold is reached.
  • [0259] Receiver ends pump operation when pump-off command is received.
  • [0260] Receiver ends pump operation if a threshold of missed pump-on packets is reached to avoid flooding user.
  • [0261] User-initiated pairing of 2.4 Ghz random channels/frequencies and pipe addresses from a matrix of legal channels and addresses.
  • [0262] Over 1 trillion pairing options eliminates cross-talk and interference.
  • [0263] User-selectable stream/flow control via SW enabled/controlled pulsed-width modulation of the signal to the pump from the receiver
  • [0264] User can set stream/flow control via the push button/transmitter
  • [0265] Transmitter sends user input for flow control to the receiver
  • [0266] Receiver accepts input from the transmitter and enters new is operational mode for flow based on the input from the transmitter/button assembly.

[0267] With respect to printed circuit boards 120 and 220, the following provisions, adaptations or modifications may also be made:

• • [0268] Identical control assemblies for transmitter (Tx) and receiver (Rx).
  • [0269] Software (SW) defined role (Tx, Rx) based on device connections to PCB.
  • [0270] On board potentiometer for hardware controlled flow rate.
  • [0271] Reprogrammable microprocessor to provide upgrade capabilities.
  • [0272] Onboard automotive grade voltage regulator to provide for operation of either module in voltages ranging from 6 v to 24 v DC.
  • [0273] Electronic circuit and components provide voltage spike and surge suppression, electro-magnetic interference (EMI) suppression, reverse polarity protection.

[0274] System 10 may further be configured to include one or more optical switches, fingerprint readers, or proximity sensors. System 10 can be configured to provide relatively effortless hydration at any speed in any terrain. Constant hydration bursts can relieve user tension and heighten or improve user focus. Regular hydration bursts provided to a user are more beneficial than periodic gulps of liquid in larger amounts.

[0275] In some embodiments, a relay may be connected to pump 300 and be driven by first control assembly 102 such that larger electrical currents may be employed, and larger devices can be controlled remotely, using system 10.

[0276] Additionally, note that system 10 is not intended to be limited to embodiments employing the specific Arduino-compatible processors and devices, the specific circuits and schematics, or the specific programming code disclosed and described herein. Instead, and as those skilled in the art will appreciate immediately after having read and understood the specification, drawings and claims hereof, many other types of processors, circuits, programs and programming code other than those disclosed explicitly herein may be employed without departing from the spirit and scope of the various inventions disclosed and described herein.

[0277] System 10 may also be modified to permit its use shipboard, on a boat, or in a building or building basement as a bilge or sump pump. System 10 may also be modified to permit its use by handicapped persons who are wheelchair- or bed-bound. Switch or control 215, for example, may be a proximity sensor or motion sensor, or may be configured to detect a user's eye motions and respond accordingly thereto. Indeed, system 10 can be configured to operate in conjunction with any device requiring on/off burst operation for the delivery of a fluid, and can be configured to enable remote control of devices where wires can be difficult or dangerous to employ.

[0278] Upon having and understood the present specification and drawings, those skilled in the art will understand that at least some of the various embodiments disclosed and described herein solve certain problems and provide certain solutions not existing in the prior art, such as: (a) providing a portable hydration system where a user interface or a fluid reservoir/pump/control assembly can be uniquely paired to one or multiple users; (b) providing hydration to a user using wireless control in an essentially hands-free and non-distracting manner; (c) wirelessly controlling a hydration system and not requiring regular manual manipulation of a hydration hose or nozzle (and therefore not requiring a user to let go of a steering wheel or handlebar; (d) permitting multiple users to share the same vehicle but use their own wirelessly-controlled hydration packs; (e) permitting a user to easily adjust the operational parameters of a hydration system; (f) permitting a user of a wireless hydration system to employ multiple communication channels to avoid cross-talk and interference with other wireless devices; (g) permitting a user to select wireless communication channels; (h) permitting a hydration system to operate over a range of electrical voltages and with different types of power supplies; (h) providing on-board diagnostics to a user regarding, for example, the performance parameters of a hydration system; (i) providing a hydration system with on-board surge and EMI protection.

[0279] The above-described embodiments should be considered as examples of the invention, rather than as limiting its scope. In addition to the foregoing embodiments of the invention, review of the detailed description and accompanying drawings will show that there are many other embodiments of the invention. Accordingly, many combinations, permutations, variations and modifications of the foregoing embodiments of the various embodiments of the invention not set forth explicitly herein will nevertheless fall within the scope of such various embodiments. For example, and as described above, the various embodiments of the invention are not limited to means and methods for providing drinkable fluids to a user, and my instead be used to pump fluids from a bilge or a sump, or to otherwise controllably transfer fluid from one location to another.
