DETAILED DESCRIPTION

(42) Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.

(43) Referring to FIG. 1, an apparatus of the present disclosure for monitoring and displaying shower water flow is illustrated generally at 100. The apparatus is depicted in an operative position between a water pipe 110 and a shower head 120. Generally, any standard shower head can be used including a handheld nozzle with a long flexible hose. The apparatus 100 can include a power unit 130 and a display unit 140, connected together, for example, by a ball-and-socket joint 150.

(44) The ball-and-socket joint 150 allows a user to reposition the front face 156 with its LCD panel 160 and (waterproof) speaker 164 as desired relative to the power unit 130, as can be understood by the arrows A1, A2 in FIG. 39. The user may want to reposition it because of his height, where he likes to stand (or sit) in the water spray W or where he likes to stand (or sit) in the shower stall relative to the front face 156. The front face 156 conveys shower water information to him via the LCD panel 160 and the speaker 164, as is described in detail in this disclosure.

(45) The power unit 130 can also be referred to as a first unit, a recharging unit, a first portion, a water flow path unit, a water temperature unit, a power portion or the like. It can include a housing 180 having a front nipple 184, a rear nipple 188, and a shower water flow path 200 from the rear nipple to the front nipple. The front nipple 184 can have external threads 204 for screwing into a shower head 120. The rear nipple 188 can have internal threads 206 for screwing onto a water pipe 110.

(46) A hydroelectric power generator 210 can be provided in the housing 180 to generate electricity from the water flowing in the water flow path 200. And a temperature sensor 220 (such as a thermistor (FIGS. 10, 11, 21 and 29)) can also be provided in the housing 180 proximate to (in) the water flow path 200 to measure the temperature of the water. The generator 210 can have a generally round shape and can be generally two inches in diameter and generally 1.5 inches thick.

(47) The operation/construction of the hydroelectric power generator 210 will now be described. A hydraulic turbine converts the energy of the flowing water in the water flow path into mechanical energy, and a hydroelectric generator converts this mechanical energy into electricity. The operation of the generator can based on the Faraday principles that when a magnet is moved past a conductor, it causes electricity to flow. In a large generator, electromagnets are made by circulating direct current through loops of wire wound around stacks of magnetic steel laminations. These field poles are mounted on the perimeter of the rotor. The rotor, which is attached to the turbine shaft, rotates at a fixed speed. When the rotor turns, it causes the field poles (the electromagnets) to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the output terminals of the generator.

(48) The display unit 140 can also be referred to herein as a second unit, a second portion, a display assembly unit or the like. The display unit 140 can include a visual and/or audio display assembly 230, which can include the LCD panel 160 and the speaker 164, a printed circuit board assembly 240, and a rechargeable battery 250, which can be a rechargeable 3.7 Volt lithium ion battery.

(49) The printed circuit board assembly 240 can have, for example, a capacitor, a circuit test button, a plurality of LEDs, a resister, an IR receive sensor, a DC-to-DC regulator, at least one battery charging control chip and a PIN slot connector.

(50) The hydroelectric power generator 210 can generate three-phase AC by water flowing in the water path and the display unit 140 can include circuits that rectify, filter and stabilize the AC to 5V DC.

(51) The display unit 140 can include the battery 250, a battery charge control circuit and a bridge rectifier 254 (e.g., FIG. 31A) between the power unit and the battery charge control circuit 256 (see FIG. 21). And the display assembly 230 can include an audio circuit and an LED display circuit. FIG. 21 shows the power unit 130 in the upper dotted line box and the display unit 140 in the lower dotted line box.

(52) The printed circuit board assembly 240 can control the operation of the display assembly 230. And the battery 250 can power the display assembly 230. Wires 270 can pass through the ball-and-socket joint 150 and deliver AC to the printed circuit board assembly 240, which converts it to DC, which is sent to the battery 250 to recharge it. Wires 270 from the temperature sensor 220 can similarly pass through the ball-and-socket joint 150 to the printed circuit board assembly (PCBA) 240 to communicate water temperature information, such as by voltage changes, to the assembly for controlling the shower session of the display assembly 230. The temperature sensor 220 and the wires 270 can be seen in FIGS. 10 and 11, for example.

(53) The three wires 270 shown for the thermistor 220 can be power, ground and data wires. The thermistor 220 can have different resistance values in different water temperatures. The resistance values can be transferred to the MCU (microcontroller unit) 274 (on/of the PCBA), and the MCU will have different actions according to the different resistance values.

(54) The display assembly 230 (and the remote control) can be powered by the battery 250, which is recharged by the hydroelectric power generator 210 in the power unit 130 and powered by water flowing in the flow path. Wires 270 (FIG. 10, for example) from the power generator 210 can transmit the AC current to the display unit 140 where it is converted by the controller to DC current, which recharges the battery 250. When the controller detects incoming electricity from the power generator 210 it knows that the water to the power unit 130 has been turned on and that it can start the shower session. Similarly, when the controller then detects no incoming electricity it knows that the water has been turned off and thus it can end the shower session.

(55) Details of the components and the construction of the power unit 130 are shown in the exploded perspective views of FIGS. 6, 7 and 8 and the cross-sectional view of FIG. 9. Referring thereto the two halves of the housing are illustrated, namely the top cover 280 with the nipple and the bottom cover 290 with nipple. Each housing cover 280, 290 can have a respective half of the socket portion 294, 298 of the ball-and-socket joint, as can be seen in FIG. 8; and FIG. 9 shows them mated with the covers assembled.

(56) The covers 280, 290 can be mated and held together with nuts 300, receptacles 304 in the covers and screws 308. Rubber plugs 320 can cover the screw ends, preventing water intrusion, but still allowing the power unit to be disassembled. The hydroelectric power generator 210 can include, as an example, a first o-ring 340, a power inner housing 350, a dynamo 360, an impeller 370, a power inner cover 380 and a second o-ring 390, as shown in FIG. 6.

(57) Similarly, details of the components and construction of the display unit 140 are shown in the exploded perspective view of FIGS. 15, 16 and 17 and the cross-sectional view of FIG. 18. The housing can include a display top cover 400 and a display bottom cover 410, both of which include opposing halves of the ball 420, 430 of the ball-and-socket joint. When the top and bottom covers 400, 410 are assembled together the ball halves mate and the pegs 440 of the upper ball half fit into the openings 444 in the lower ball half.

(58) Referring to FIGS. 15-18, the display covers 400, 410 can be mated and held together using receptacles in the covers and screws 444. Rubber plugs 450 can cover the screw ends, preventing water intrusion, but still allowing the power unit to be disassembled. Inside the housing can be the LCD display 460, the display inside housing 480, the display seal 490, the display o-ring 500, the printed circuit board assembly 240, and the battery 250. On the side of the display bottom cover (or the bottom edge) can be a display button (mute button) 530 and a USB port 540 having a cover.

(59) The display assembly 230 can include (for the LCD) three (or two) green LED lights 550, three (or two) yellow LED lights 560 and three (or two) red LED lights 570, and their operation can be controlled by the micro-controller 275 of the printed circuit board assembly 240. Referring for example to FIG. 14, one or two green lights can illuminate the word Shower 580 and a bubbles symbol 590, and one green light can illuminate a Smiley face 600 in the color bar. One or two yellow lights can illuminate the word Rinse 610 and a water drop symbol 620, and one yellow light can illuminate a Clock or stop watch symbol 630 in the color bar. One or two red lights can illuminate the Stop 640 and hand symbol 650, and one red light can illuminate a Sad Face symbol 660 in the color bar. (The LEDs are illustrated, for example in FIGS. 26, 30, 31, and 34.) FIG. 14 also illustrates the speaker opening for the audio sounds/signals.

(60) The operation of the display assembly 230 for an exemplary shower session of the present disclosure can be understood with reference to the flow charts 670 and 680 of FIGS. 19 and 20. A user turns the water on and water flows through the hydroelectric power generator 210, causing electricity to be generated and transmitted to the printed circuit board assembly 240, which awakens the circuit. The buzzer 690 plays back three beeps. (The buzzer (FIGS. 21 and 27) in addition to emitting a buzzing sound, can be a speaker capable of emitting a variety of sounds including voice messages, as discussed herein.) The temperature sensor 220 is sensing the temperature of water flowing in the water flow path and sending corresponding signals to the PCBA 240. The signals can be corresponding voltages and the sensor 220 can be a thermistor, as mentioned previously. The PCBA 240 can continually check the temperature or check it periodically, such as every sixty seconds. (See flow charts 670 and 680.)

(61) The thermistor 220 has different resistance values in different water temperatures, and the display unit 140 can include a microcontroller and the display assembly 230. The different resistance values when actuated cause the microcontroller/MCU 274 to instruct the display assembly 230 to take different actions.

(62) When the PCBA 240 receives a signal (from the thermistor 220 and via a wire) indicating that the shower water has reached a predetermined temperature, the timer in the PCBA starts the shower session. It can start it by causing the buzzer 690 to beep three times and the green LEDs to be illuminated. After the passage of a first time interval, representing the shower stage, the green LED lights are turned off and the yellow LED lights are illuminated. The first time interval can be programmable by the user/customer as discussed herein.

(63) Turning the yellow LED lights on represents the start of the rinse stage of the shower session, which lasts for a second time interval. The second time interval can be programmable by the user as discussed herein.

(64) After the passage of the second time interval, the first phase of the stop stage begins with the illumination of the red LED lights and the buzzer beeping three times. The first phase can last for a third time interval, and can also be programmable by the user.

(65) As examples, the shower stage can last between five and seven minutes and the rinse stage can last between forty-five seconds and ninety seconds. And the first phase of the stop stage can last between forty-five seconds and ninety seconds.

(66) After the passage of the third time interval, the second phase of the stop stage starts and it lasts until the water is turned off. During the second phase, the red LED lights can flash on and off and the buzzer can beep once each second. It can be a more urgent audio and/or visual display than that of the first phase, and also a more annoying one, e.g., more frequent, louder and/or shriller. Turning the water off causes the water switch to turn off, and after thirty seconds, for example, the apparatus 100 goes into a sleep mode. The sleep mode can be understood, for example, from the operating logic diagram of FIG. 20.

(67) As an example, the factory settings for the time periods can be six minutes for the shower stage, one minute for the rinse stage and one minute for the first phase of the stop stage, and three minutes to avoid the alert stage.

(68) The grace period (first phase) can be approximately one minute and the audio stop display can be a continuous beeping sound or repeating message. The shower session can include a delay of three (or more) minutes prior to commencement of a second shower session.

(69) In other words, the display unit 140 can play pre-recorded audio messages at specified time intervals like those discussed below.

(70) First sound notation: Chime, Chime! Audible notation when the water temperature reaches pre-determined shower temperature (e.g., ninety degrees), thereby alerting the user that the water is now warm enough to shower, and thus preventing minutes, and gallons of hot water from going down the drain. (This event also starts the lighting sequence on the display unit 140, accompanied by the Green Light, and illumination of the Smiley face 600.) (See FIG. 14.)

(71) Second sound notation: When the allotted showering time (shower stage) has been reached an audible chime is played to remind the user that his shower (soaping) time is up, and to transition to a Rinse cycle, accompanied by a Yellow Light and a Stop Watch image or water drops 620 on the color bar. (See FIG. 14.)

(72) Third sound notation: When the allotted Rinse time allocation has been reached, there is a third sound notation accompanied by a red light, and an Open Palm image 650 on the color bar. (See FIG. 14.)

(73) Fourth sound notation: When the allotted time to stop showering has been reached, signaling the individual to exit the shower, a Red light, Frowning Face 660 appear on the color bar. (See FIG. 14.)

(74) Fifth sound notation: Should the user fail to turn the water off after being notified to stop: a continual chime, chime, chime sounds as the Open Palm image 650 (FIG. 14) blinks on and off. This blinking and chiming continue until the water is turned off.

(75) The apparatus can also have an alert mode, which can be considered as part of the shower session or as an adjunct thereto. The alert mode discourages users from short cutting the shower session by turning the water off before the start of the first phase (or alternatively the second phase) of the Stop Stage and then quickly (before the passage of a relatively short predetermined time period) turning the water back on, and thereby avoiding the (annoying) second phase (or the first and second phases) of the Stop Stage.

(76) As an example of the alert mode if the user turns the water off before the Stop Stage of the shower session and then turns the water back on before a predetermined time period (such as three minutes or between two and fifteen minutes) has passed, the display assembly 230 emits an audio and/or visual alert such as beeping sounds accompanied by blinking lights. Another example can be blinking lights accompanied by a voice message from the speaker/buzzer, such as please exit the shower, allotted shower time has been exceeded; please exit or something similar. In other words, the alert session discourages a user from obtaining a long shower time by avoiding the full shower session, that is, by avoiding the annoying audio/visual signals of the stop stage.

(77) In other words, should a person turn the water off, during for example the rinse stage, the timer continues normally, per programming instructions. The apparatus carries on with its orders and timing sequence. During Stop Supreme (the alert mode) the idea is to make annoying lights and sounds which last until the user turns the shower water off. Once the water is turned off, there is a program, such as a three-minute program, that runs internally. Should the water be turned back on, during that program, the Stop Supreme alert mode starts all over again, and the three minutes gets re-set back to the top.

(78) Electricity being delivered to the controller from the hydroelectric power generator 210 signals that water is flowing in the water flow path, and electricity not being delivered to the controller signals that water is not flowing in the water flow path.

(79) The apparatus can be sold or otherwise made available to the user with a predetermined temperature and the shower session fixed, or with the predetermined temperature and/or shower session customizable by the user. One way of customizing is to use a remote control unit (FIGS. 31B and 33) 710 that operatively connects to the controller via an IR sensor 730. Referring for example to FIGS. 31A and 31B, the display unit 140 can include an infrared sensor 730 that is configured to receive signals from the remote control. The remote control 710 can allow a user to re-program the controller or PCBA to change the volume, duration and/or sound of the audio signals, to change the times of at least one of the stages of a shower session of the apparatus and/or to change the water temperature setting of the start of the shower session. And referring again to FIGS. 31A, 31B and 32, the remote control 710 can have an LCD panel 734, a first button 740 for adjusting the volume of an audible display, a second button 760 for adjusting the length of a shower stage of the session, a third button 780 for adjusting the length of a rinse stage of the session, a fourth button 820 for adjusting the length of a stop stage (or a first phase of the stop stage) of the session, and a fifth button 840 for mute.

(80) In other words, the infrared sensor 730 allows for easy re-programming without having to remove the apparatus 100 from the shower pipe 110 (see FIG. 1). The remote control 710 can be used to re-program: the volume (or the buzzer/speaker) to make it louder or softer; the time to make the shower session stages (e.g., shower, rinse) longer or shorter; and the (thermistor) temperature to raise or lower the temperature start setting.

(81) Another way to customize/reprogram the operation of the display assembly 230 can be to plug one end of a cord into the USB port 540 of the display unit and the other end connected to a computer. With the computer accessing a website 850 (see FIG. 35) of this disclosure and synched with the controller, the user chooses by clicking on the appropriate areas on the page on the computer monitor the desired water shower temperature, the lengths of the wash, rinse and stop (first phase) stages, the audio selections for each of the stages, and/of the blinking and/or beeping rates for the alert session or mode.

(82) More particularly, with the computer accessing the website and synched up to the apparatus 100 and its internal controller, the user can re-program the factory settings of the controller. The apparatus 100 can be synched up via the USB port 540 on the display unit 140. Thereby, the user can program the desired starting temperature, the duration of the shower stage, the duration of the rinse stage, and the duration of the stop grace period phase. Using the computer/device interface 850, the user can also select and re-program the factory set audio alerts, selecting from a list of sound effects and volumes. These sound effects and/or voice recordings can be used to alert the user that the shower temperature has been reached, the shower time is up, transition to rinse stage, the rinse time is up transition to the stop stage, and/or the grace period is over, turn the water off and exit the shower.

(83) Again, personalized sound can be created and installed into the apparatus 100 via a personal computer and the USB port 540. Virtually any audio message can be created on the computer and transferred to the apparatus 100. Beeps, alarms, sirens, dogs barking, drums, musical cues, and even record your own message statements can be recorded via the personal computer via granted access to company website. Once customized and personalized on the website 850, the audio message can be transferred from the computer into the apparatus 100, via the USB port 540. It thereby resembles a personal app for the shower. For example, the apparatus can be able to tell the user's child in the user's own voice, such as Henry, your sister's waiting, get out of the shower!!

(84) With reference to FIG. 35, for example, further descriptions of the PC interface 850 to personalize the apparatus follow.

(85) A. Customer Programs the Time:

(86) 1. Customer attaches a USB cable to a port 540 in the apparatus 100 and attaches the other end of his cable to his computer.

(87) 2. Computer talks with the apparatus 100 and takes guest/customer to Company (e.g., WaterSmartTechnology) websites: Program iMShowerSmart

(88) 3. Program syncs with the computer.

(89) 4. Customer clicks and increases or decreases temperature(s) to the desired temperature(s) 870.

(90) 5. Customer increases or decreases minutes for Shower (stage), by touching + or icon 880.

(91) 6. Customer increases or decreases seconds for Shower, by touching + or icon 890.

(92) 7. Customer increases or decreases minutes for Rinse (stage), by touching + or icon 900.

(93) 8. Customer increases or decreases seconds for Rinse, by touching + or icon 910.

(94) 9. Customer increases or decreases minutes for Shower (stage), by touching + or icon 920.

(95) 10. Customer increases or decreases seconds for Shower, by touching + or icon 930.

(96) B. Customer Programs the Sound:

(97) 1. Customer selects sound effects, by highlighting the selection, pressing the play button to hear it, and if desired hitting the Import Sound tab 950 to import that sound effect into Audio Alert #1 then pressing the SET button.

(99) 3. Customer selects sound effects, by highlighting the selection, pressing the play button 960 to hear it, and if desired hitting the Import Sound tab 980 to import that sound effect into Audio Alert #3, then pressing the SET button.

(100) 4. Customer selects sound effects, by highlighting the selection, pressing the play button to hear it, and if desired hitting the Import Sound tab to import that sound effect into Audio Alert #4, then pressing the SET button.

(101) Once all of the pre-sets have been loaded, the customer presses the OK button 990 and the data/programming is transferred to the computer program.

(102) When the water reaches a pre-determined temperature it signals the audio deck, which can play the audio message selected. Shower temperature has been reached or whatever is chosen. Many people forget the shower is running, or wait long past its ready stage. There is a reminder, a nudge, pursuant to an aspect of this apparatus, such as Hello! Shower's ready! Thereby millions of gallons of hot water that otherwise would go directly down the drain can be saved.

(103) An anti-theft chain (not shown) can also be added, to chain the apparatus 100 to the water supply pipe 110 (for example), thereby preventing theft of the apparatus such as when the apparatus is being used in public, non-residential locations.

(104) Thus, the apparatus 100 can have one or more of the following advantages: shorten shower times; save energy; save water; slash carbon; extend the life of the boiler or water heater; reduce energy and extend the life of sewer systems and pumping equipment; reduce water wars among family members waiting for the shower; create general environmental awareness; create shower courtesy amongst people who share a shower stall; prompt users when the shower temperature is reached; and be a change agent, inspiring general conservation and environmental responsibility.

(105) Accordingly, features of the present disclosure can include: built-in water generator to generate power to charge the battery of inside and supply to product; built-in temperature sensor to detect the water temperature; resettable buzzer volume by button and remote controller; resettable shower mode, rinse mode and stop mode time by remote controller; resettable initialization temperature setting by remote controller; rechargeable battery from micro USB from PC or most power and mobile power adapters; ten meter long range remote control; three colors LEDs for three types mode; easy install and uninstall; all settings (except buzzer volume resettable by remote and button) can use remote controller; and easy for the administrator to control and manage.

(106) Exemplary specifications of the apparatus 100 can include Micro USB 5V 500MA Input voltage; 1050 mA/h polymer battery 350; a 3-phase motor; and 22 cm7 cm8.5 cm dimensions.

(107) A battery voltage checking and charging capability can be included. For example, once the MUC (the controller of the PCBA) receives the Motor off trigger, the MCU checks the battery voltage. If the battery voltage 3.4V, the MCU goes into Stop Status. If the battery voltage <3.4V, LED4 flashes twice per second and there will be alert voice two seconds per thirty seconds, and this can last ten hours to alert the consumer to charge the battery. When the apparatus is charging from the USB port, the LED4 can be on during the charge and LED6 (e.g., FIG. 33) can be on once the charging is completed.

(108) FIG. 21 is a circuit block diagram shown generally at 990 of the apparatus. FIG. 22 shows generally at 1000 the Dynamo motor power generation by water flow, namely three-phase AC is generated by the water flowing through the dynamo motor 210 is rectified, filtered and then stabilized to 5V DC by the DC To DC LDO. FIG. 23 shows generally at 1010 the battery charge control where power from the USB (Micro USB connector) 540 and the DC 5V rectifier (dynamo motor, see FIG. 22) are sent through that circuit that manages the charge cycle for the battery 250. FIG. 24 shows generally at 1020 a battery protection circuit that protects the battery 250 from charge and discharge shorts and over current protection. FIG. 25 shows generally at 1030 the voltage transformer wherein voltage from the battery 250 is transformed to 2.8V to supply the MCU, LEDs, audio function and IR receiver.

(109) FIG. 26 shows generally at 1040 the processor, which is the main MCU that stores logic for controlling timing function, LED display, audio output, audio volume control, IR input, temperature detection and battery voltage detection and warning. FIG. 27 shows generally at 1050 the audio amplifier and buzzer for providing the user with audio feedback. FIG. 28 shows generally at 1054 the IR sensor to interface with the IR remote for adjusting operating parameters such as time and audio volume. FIG. 29 shows generally at 1060 the sensor for detecting the temperature of water flow. FIG. 30 shows generally at 1070 the LED inductor and the LED display that provides the user with visual feedback.

(110) FIG. 36 is a top perspective view of a top portion 1100 of a packaging insert for the apparatus 100. FIG. 37 is a bottom perspective view of the top portion 1100 of the packaging insert. And FIG. 38 is a top perspective view of a bottom portion 1300 of the packaging insert and showing the apparatus 100 fitted therein. The insert 1100, 1300 can be made from recycled paper and cardboard for sturdiness, and it can be form fitted to hold and protect the apparatus 100.

(111) Thus, the apparatus 100 herein can include one or more of the following features: built-in dynamo generator to generate power from the water flow to the power unit; built-in temperature sensor to detect water temperature; user-programmable initialization temperature setting by remote controller; user programmable buzzer (via button or IR remote); user-programmable shower timer (rinse mode and stop mode times programmable by remote controller); rechargeable battery with auxiliary USB power input; IR remote with ten meter long range remote control, three color LEDs with three types of modes; and configuration/construction for easy installation and removal.

(112) Further, some of the novel aspects of the apparatus 100 are: (1) Any audio (up to seven seconds worth, for example) can be downloaded and played back at pre-determined time intervals. Even the user's own voice (or that of family members, friends or even celebrities) can be downloaded and used. (2) The apparatus can be water activated and automatically started when the water flows into it. (3) The volume can be increased or decreased via a remote control or via a computer. (4) The time lengths for the Shower: Rinse: Stop stages can be changed (by the user) via remote control or a computer. (5) Once a pre-determined shower temperature has been reached a temperature sensor initiates the timing sequences. (6) Sound effects, voice recordings, time allotments, temperature start settings can be downloaded via a USB cable and/or from a personal computer to the computer program. (7) No (additional or replacement) batteries are needed since the apparatus is powered by a water flow/mini-hydro electric power plant. (8) The shower display screen is position-adjustable via a ball and socket. (9) The shower timer is water-powered, uses red-yellow-green lights and endless sound effects and is operatively positionable between the water supply line and the shower head.

(113) The apparatus 100 thus shortens shower time, thereby saving money, water and energy while cutting CO2 emissions. It increases water and energy conservation habits in people of all ages. It can cut heating and sewer fees and shower times by three to five minutes thereby saving five to ten gallons of water per shower.
