In the illustrated embodiment, the handle 22 operates as with a standard faucet. In other words, the handle 22 may be moved between various positions to indicate a desired temperature, flow rate, and/or volume of water discharged from the faucet 12.

In the illustrated embodiment, as best shown in FIG. 3, handle 22 operates as with a standard faucet, although handle 22 does not control a mechanical valve. In other words, the handle 22 may be moved between various positions to indicate a desired temperature, flow rate, and/or volume of water discharged from the faucet 12.

More specifically, with respect to the temperature of the water, handle 22 may be rotated about the longitudinal axis of the side opening in bushing 14. At one degree of the range of rotation, the position of the handle 22 indicates full hot water (full hot position). At another degree of the range of rotation, the position of the handle 22 indicates full cold water (full cold position). Between the two degrees of the rotational range, when the position of the handle 22 is close to the full hot degree of the rotational range, the position indicates the mixing of hot and cold water with the water having the hotter temperature (mixed temperature position), and when the position is close to the full cold temperature of the rotational range, indicates the mixing of hot and cold water with the water having the cooler temperature (mixed temperature position).

The handle 22 can be moved towards and away from the side opening in the liner 14 with respect to the flow rate/volume of water. At one degree of range of movement, the position of the handle 22 indicates no flow rate/volume of water (fully closed position). At another degree of range of movement, the position of the handle 22 indicates the full flow rate/volume of water (fully open position). Between these degrees of the range of movement, an intermediate flow rate/volume of water (less than the fully open position) with a reduced flow rate/volume of water is indicated when the position of the handle 22 approaches the fully closed degree of the range of movement, and an intermediate flow rate/volume of water (less than the fully open position) with an increased flow rate/volume of water is indicated when the position approaches the fully open degree of the range of movement.

In an exemplary embodiment, faucet 12 is operable to detect movement of handle 22 and provide information based on the movement of handle 22 to set at least one parameter of the water flowing through hot water electronic valve 32h and cold water electronic valve 32 c. Faucet 12 is operable to detect movement of handle 22, either directly or indirectly. In the exemplary embodiment, based on movement of handle 22, faucet 12 provides information to set the temperature, flow rate, and/or volume of water flowing through hot water electronic valve 32h and cold water electronic valve 32 c.

Further, in the illustrated embodiment, as best shown in fig. 3, faucet 12 includes a parameter or position sensor 40. In an exemplary embodiment, the parameter or position sensor 40 is operable to detect a state of the handle 22, such as a position or movement of the handle 22, and provide information to set at least one parameter of the water flowing through the hot water electronic valve 32h and the cold water electronic valve 32c based on the state of the handle 22, such as the position or movement of the handle 22. The parameter or position sensor 40 is operable to detect a condition of the handle 22, such as a position or movement of the handle 22, ranging from a fully hot position to a fully cold position, and from a fully closed position to a fully open position. The parameter or position sensor 40 is operable to directly or indirectly detect a state of the handle 22, such as a position or movement of the handle 22. In an exemplary embodiment, based on the state of the handle 22, such as the position or movement of the handle 22, the parameter or position sensor 40 provides information to set the temperature, flow rate, and/or volume of water flowing through the hot water electronic valve 32h and the cold water electronic valve 32 c.

An electronic Plumbing fixture fitting, such as an electronic faucet, including a parameter or position sensor operable to detect movement of a handle and provide information based on the movement of the handle to set at least one parameter (such as temperature and/or volume) of water flowing through a hot water electronic valve and a cold water electronic valve is disclosed in U.S. patent No. 9,212,473 assigned to FB Global Plumbing Group LLC (FB Global Plumbing Group LLC), the entire disclosure of which is incorporated herein by reference.

Further, in the illustrated embodiment, as best shown in fig. 2 and 3, the accessory 10 and the faucet 12 include a control module 42, a user input module 44, and a power module 46.

The flow components of the control module 42 include a plurality of inlets and outlets and a plurality of flow channels. These inlet/outlet and flow passages enable easy management of flow between the incoming flow (i.e., hot water line 26 and cold water line 28) and the outgoing flow (i.e., mixed water line 30 or wand hose 18).

In the illustrated embodiment, as best shown in fig. 3, the control module 42 is operable to be mounted below a mounting surface M (such as a bar counter or sink). In an exemplary embodiment, the control module 42 is operable to be mounted on a mounting stem of the fitting 10 or faucet 12. In the illustrated embodiment, the electronic valve 32 is located within the control module 42. In the illustrated embodiment, the control module 42 includes a top or first side and a bottom or second side. The first side is opposite the second side. In the illustrated embodiment, the second side includes openings for the hoses and flow channels.

In the illustrated embodiment, as best shown in FIG. 2, the control module 42 also includes a number of electronic components. These components enable the operation of the fitting 10 or the tap 12. More specifically, these components enable the electronic valve 32 to be activated, deactivated, and controlled via user input. The control module 42 includes the electronic valve 32 and a printed circuit board ("PCB") 48. In the illustrated embodiment, a number of electronic components are mounted on the PCB 48, including but not limited to a processor 50, a memory 52, a wireless communication chip 54, and a power port 56. Processor 50 receives signals from components of fitting 10 or faucet 12 and sends signals to components of fitting 10 or faucet 12 to control operation of fitting 10 or faucet 12. For example, the processor 50 receives signals from sensors (described above and in more detail below) and sends signals to the electronic valve 32 to activate, deactivate, and control the electronic valve 32. The memory 52 may store information received from the accessory 10 or components of the faucet 12. Information may also be stored in remote memory. Exemplary storage locations for the remote memory include a user input module 44 (where the user input module 44 includes memory such as Apple iPhone (Apple iPhone) and Google's Android (Android) cell phone), a central server provided by the accessory/faucet manufacturer, and cloud services provided by the accessory/faucet manufacturer or third parties such as Google, Homekit, and IFTTT. In the illustrated embodiment, the remote storage includes a server 58 and a cloud 60.

In the illustrated embodiment, as best shown in fig. 2 and 3, the user input module 44 provides operating instructions to the electronic components of the fitting 10 or faucet 12. User input module 44 may be any module that enables user input. User input module 44 includes electronic input device(s) 62 and manual input device(s) 64. Exemplary electronic input devices 62 include activation sensors, mobile devices, voice control devices, touch screen devices, and button devices. In the illustrated embodiment, the user input module 44 includes an activation sensor 38, a mobile device 66, and a voice control device 68. Exemplary manual input devices 64 include a handle and a joystick. In the illustrated embodiment, the user input module 44 includes the handle 22. User input module 44 receives input from a user and sends signals to control module 42 or other electronic components of accessory 10 or faucet 12 to control the operation of the components of accessory 10 or faucet 12. For example, user input module 44 receives input from a user and sends signals to processor 50 to activate, deactivate, and control electronic valve 32.

In the illustrated embodiment, some components of user input module 44 (e.g., mobile device 66 and voice control device 68) are connected to control module 42 via a wireless communication connection 70 (such as a Wi-Fi connection), while other components of user input module 44 (e.g., activation sensors 38 and parameter or position sensors 40) are connected to control module 42 via a hardwired connection 72. In the illustrated embodiment, some components of user input module 44 (e.g., mobile device 66 and voice control device 68) send signals to and/or receive signals from processor 50 via a wireless communication connection 70 (such as a Wi-Fi connection), while other components of user input module 44 (e.g., activation sensor 38 and parameter or position sensor 40) send signals to and/or receive signals from processor 50 via a hardwired connection 72. However, those of ordinary skill in the art will appreciate that each component of user input module 44 may be connected to control module 42 and send and/or receive signals from processor 50 via any type of connection, including other wireless communication connections or hardwired connections such as Bluetooth, cellular, Near Field Communication (NFC), Zigbee, and Z-Wave.

In the illustrated embodiment, as best shown in FIG. 3, three electronic input devices 62 and one manual input device 64 are shown, namely the activation sensor 38 on the faucet 12, a movement device 66 that can be held or moved by a user, a voice control device 68 located on the mounting surface M, and the handle 22 connected to the hub 14 of the faucet 12 located on the mounting surface M. However, one of ordinary skill in the art will appreciate that the user input module 44 may include any number of components. Further, each component of user input module 44 may be anywhere that signals may be sent to and/or received from control module 42 and/or other electronic components (such as processor 50) of accessory 10 or faucet 12, or each component of user input module 44 may be integrally formed with accessory 10 or faucet 12 or physically connected to accessory 10 or faucet 12.

In the illustrated embodiment, as best shown in fig. 2 and 3, the server 58 and cloud 60 are connected to the control module 42 via a wireless communication connection 70 (such as a Wi-Fi connection).

In the illustrated embodiment, as best shown in fig. 2 and 3, the power module 46 provides power to the electrical/electronic components of the fitting 10 or faucet 12. In the illustrated embodiment, the power module 46 is operable to be mounted below the mounting surface M. In the illustrated embodiment, the power module 46 is connected to the control module 42 via a hardwired connection 72. In the exemplary embodiment, power module 46 includes a battery power source. In the exemplary embodiment, power module 46 includes an AC power source.

During operation of the electronic valve 32, a user activates, deactivates, and controls the electronic valve 32 using the user input module 44. When the user appropriately triggers the user input module 44, the electronic valve 32 is activated, deactivated, or otherwise controlled. For example, a user may trigger user input module 44 by triggering activation sensor 38, pressing an appropriate button on mobile device 66, stating a particular command to voice control device 68, and/or opening, closing, and/or moving handle 22. For voice control, the electronic valve 32 is activated when the user says "open faucet". Similarly, when the user says "turn off the faucet", the electronic valve 32 is deactivated. Further, when the user says "increase temperature", "decrease temperature", "increase flow", or "decrease flow", the electronic valve 32 is controlled to complete the requested action. The command may be predetermined. Further, these commands may be customized. For example, a user may activate the electronic valve 32 by saying "start flow" rather than "open a faucet". Similarly, the user may deactivate the electronic valve 32 by saying "stop flow" rather than "turn off the faucet".

As used herein, "activating a valve" means moving the valve to or holding the valve in an open position regardless of the volume or temperature of the flowing water, while "deactivating a valve" means moving the valve to a fully closed position.

When referring to activating or deactivating the electronic valve 32 "when the user appropriately activates the user input module 44," the electronic valve 32 may be activated or deactivated immediately upon activation of the user input module 44 or after a predetermined period of time after the user input module 44 has been activated.

In the illustrated embodiment, the fitting 10 and the faucet 12 include sensors. In the illustrated embodiment, the sensors include a start sensor 38, a parameter or position sensor 40, a temperature sensor 74, a flow sensor 76, a pressure sensor 78, and a valve sensor 80. The actuation sensor 38 and the parameter or position sensor 40 are described above. The temperature sensor 74 is operable to detect the temperature of the water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The flow sensor 76 is operable to detect the flow rate of water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The pressure sensor 78 is operable to detect the pressure of water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The valve sensor 80 is operable to detect a position of the electronic valve 32 and/or a motor that drives the electronic valve 32. The sensor sends a signal indicative of the sensed information to the processor 50.

The information detected by the sensor is used to control the operation of the fitting 10 or faucet 12. The information detected by the activation sensor 38 may be used to activate and deactivate the fitting 10 or faucet 12. The information detected by the parameter or position sensor 40 may be used to determine the temperature, flow rate and/or volume of water desired by the user. The information detected by the temperature sensor 74 may be used to maintain the temperature of the water discharged from the fitting 10 or faucet 12. The information detected by the flow sensor 76 may be used to determine whether there is a flow of water being discharged from the fitting 10 or the faucet 12 or to maintain a flow rate of water being discharged from the fitting 10 or the faucet 12. The information detected by the pressure sensor 78 may be used to maintain the pressure of the water discharged from the fitting 10 or faucet 12 or to determine the volume of water discharged from the fitting 10 or faucet 12. Information detected by the valve sensor 80 may be used to open and close the electronic valve 32.

In the illustrated embodiment, the fitment 10 and faucet 12 include a clock/timer 82. The clock/timer 82 is operable to provide a date and time of action or a measurement time interval. For example, the clock/timer 82 may provide the date and time of activation or deactivation of the accessory 10 or faucet 12, or measure the time interval from activation of the accessory 10 or faucet 12 to deactivation of the accessory 10 or faucet 12.

Measuring system

In an exemplary embodiment, the fitting 10 or faucet 12 includes a measurement system. In an exemplary embodiment, user input module 44 includes a mechanism to receive from a user a value(s) of a parameter(s) (e.g., volume or volume and temperature) of water to be delivered through fitting 10 or discharge outlet 24 of faucet 12, and a mechanism to deliver the value(s) of the parameter(s) to the user via water delivered through fitting 10 or discharge outlet 24 of faucet 12.

Generally, in an exemplary embodiment where user input module 44 receives a desired volume of water from a user to be delivered through drain outlet 24 of fitting 10 or faucet 12, user input module 44 sends a signal to processor 50 indicating the desired volume. Processor 50 receives signals from user input module 44 and sends signals to electronic valve 32 to actuate. As a result, water will be delivered through the fitting 10 or the discharge outlet 24 of the faucet 12. The flow sensor 76 detects the volume of water delivered and sends a signal indicative of the detected volume to the processor 50. The processor 50 receives a signal from the flow sensor 76 and sends a signal to the electronic valve 32 to deactivate once the detected volume is approximately equal to the desired volume.

Generally, in an exemplary embodiment in which user input module 44 receives a desired value of the temperature of water to be delivered through fitting 10 or discharge outlet 24 of faucet 12 from a user, user input module 44 sends a signal to processor 50 indicative of the desired temperature. Processor 50 receives signals from user input module 44 and sends signals to electronic valve 32 to actuate. As a result, water will be delivered through the fitting 10 or the discharge outlet 24 of the faucet 12. The temperature sensor 74 detects the temperature of the conveyed water and sends a signal indicative of the detected temperature to the processor 50. Processor 50 receives signals from temperature sensor 74. If the detected temperature is not approximately the same as the desired temperature, the processor 50 sends a signal to the electronic valve 32 to control the temperature of the delivered water (e.g., to decrease or increase the temperature based on whether the detected temperature is above or below the desired temperature). Further, if the detected temperature is not approximately the same as the desired temperature, the temperature sensor 74 continues to detect the temperature of the delivered water and send a signal indicative of the detected temperature to the processor 50, and the processor 50 continues to receive a signal from the temperature sensor 74 and send a signal to the electronic valve 32 to control the temperature of the delivered water until the detected temperature is approximately the same as the desired temperature.

In an exemplary embodiment, the measurement system includes water flow ramp up and ramp down features to improve accuracy and user experience. More specifically, this feature reduces errors from system components, enables a user to locate (and reposition, if necessary) a container into which water is delivered under a stream of water, and reduces splashing if the container is small.

In the exemplary embodiment, the water flow ramp up and ramp down characteristics include an initial low flow rate after electronic valve 32 is opened and a final low flow rate before electronic valve 32 is closed. Further, in the exemplary embodiment, this feature includes a variable water flow rate after the initial low flow rate and before the final low flow rate. Further, in the exemplary embodiment, the water flow rate is ramped up slowly to the full flow rate after electronic valve 32 is opened, and the water flow rate is ramped down slowly from the full flow rate before electronic valve 32 is closed.

In an exemplary embodiment, the flow rate ramps up in five stages, and the flow rate ramps down in five stages. However, one of ordinary skill in the art will appreciate that the flow rate may be ramped up in more or less than five stages, the flow rate may be ramped down in more or less than five stages, and the number of ramp up stages may be different than the number of ramp down stages.

In an exemplary embodiment, the flow rate ramps up at a linear rate and the flow rate ramps down at a linear rate. However, one of ordinary skill in the art will appreciate that the flow rate may ramp up at a non-linear rate, the flow rate may ramp down at a non-linear rate, and the rate of ramp up may be different than the rate of ramp down.

In the exemplary embodiment, the time at which the flow rate begins to ramp down is calculated based at least in part on the time required for electronic valve 32 to close or the volume of water delivered while electronic valve 32 is closing. In other words, the moment at which the flow rate begins to ramp down is approximately equal to the total time required to deliver the desired volume of water minus the time required to close the electronic valve 32. In still other words, the volume at which the flow rate begins to ramp down is approximately equal to the desired volume of water minus the volume of water delivered when the electronic valve 32 is closing. The time or volume at which the flow rate begins to ramp down is a factor of the flow rate and pressure of the delivered water.

In an exemplary embodiment, when the volume of water to be delivered is sufficiently small, the flow rate may never reach the full flow rate.

In an exemplary embodiment, when a volume of water is to be delivered at a specified temperature, the cold water electronic valve 32c is opened before the hot water electronic valve 32h, and the hot water electronic valve 32h is closed before the cold water electronic valve 32 c.

In an exemplary embodiment, when a volume of water is to be delivered at a specified temperature, control of the temperature of the delivered water is stopped at approximately the same time as the flow rate ramp begins.

In an exemplary embodiment, when a volume of water is to be delivered at a specified temperature, the water is delivered until the water flow approximately reaches the specified temperature. Once the water flow reaches approximately the specified temperature, the water flow stops and the user needs to trigger the activation sensor 38 in order to deliver the desired volume of water. Once the user triggers the activation sensor 38, the fitting 10 or faucet 12 delivers the desired volume of water. As a result, a desired volume of water is delivered at approximately the specified temperature.

Exemplary embodiments for inputting data into a measurement System

In an exemplary embodiment, user input module 44 displays the option(s) and parameter(s) with corresponding field(s) for the user to enter the value(s) and select the option(s) (see fig. 4a, 6a, and 8 a). As shown in fig. 4a, 6a and 8a, an option is selected if a point next to the option is on the right side in the corresponding input field, and the option is not selected if a point next to the option is on the left side in the corresponding input field. The value(s) and option(s) may be saved as presets. The presets are saved value(s) of parameter(s) and selection(s) of option(s) of water to be delivered through the fitting 10 or discharge outlet 24 of the faucet 12. The user input module 44 enables a user to create and select presets. The user input module also enables the user to name the presets.

Example 1 measurement of volume-default temperature

In an exemplary embodiment where a volume of water is delivered at a default temperature, user input module 44 receives a desired value for the volume of water to be delivered through fitting 10 or discharge outlet 24 of faucet 12 from a user. The user may input the desired value of the volume of water to be delivered by selecting a previously saved preset or by entering the desired value via a voice command or another input device. The user input module 44 sends a signal to the processor 50 indicating the desired volume. Processor 50 receives signals from user input module 44.

In an exemplary embodiment, if the user input module 44 does not receive from the user a desired value for the temperature of water that should be delivered through the fitting 10 or the discharge outlet 24 of the faucet 12, the default temperature is the coldest temperature possible. However, one of ordinary skill in the art will appreciate that the default temperature may be the intermediate mix temperature, the hottest possible temperature, or any other temperature.

Fig. 4a shows an exemplary screen displayed by the user input module 44 (i.e., the mobile device 66) where the user is creating a preset with a desired value of volume but no desired value of temperature.

Fig. 4b shows an exemplary screen displayed by the user input module 44 (i.e., the voice control device 68) where the user has provided the desired value for the volume, but not the desired value for the temperature (the time of day is displayed with the desired value for the volume).

In an exemplary embodiment where user input module 44 receives from the user a desired value for the volume of water to be delivered through fitting 10 or discharge outlet 24 of faucet 12, user input module 44 may provide the user with the option "water immediately? "(see FIG. 4 a).

If the user selects the option to immediately dispense water, the user input module 44 sends a signal to the processor 50 indicating that the desired volume of water should be delivered immediately upon receipt (e.g., upon selection of a preset or input of the desired volume). Processor 50 receives signals from user input module 44 and sends signals to electronic valve 32 to activate and deliver the desired volume. As a result, the fitting 10 or faucet 12 will immediately begin delivering the desired volume of water upon receiving the desired volume of water.

If the user does not select the option to go out immediately or the user is not given the option to go out immediately, user input module 44 instructs the user to trigger activation of sensor 38 when they are ready for the desired volume to be delivered. For example, user input module 44 displays or speaks a message to the user such as: "wave hand to start water" and "will send out [ desired volume ]" (see fig. 5a) or "wave now over sensor to send out [ desired volume ]" (see fig. 5 b). The activation sensor 38 is triggered by the user. The activation sensor 38 sends a signal to the processor 50 indicating that the desired volume should now be delivered. The processor 50 receives a signal from the activation sensor 38 and sends a signal to the electronic valve 32 to activate and deliver the desired volume. As a result, the fitting 10 or tap 12 will begin delivering the desired volume of water at that time.

The electronic valve 32 receives a signal from the processor 50 to activate and deliver the desired volume of water. The electronic valve 32 opens and begins delivering water at an initial low flow rate. The electronic valve 32 gradually increases the flow rate of the delivered water until the electronic valve 32 delivers water at the full flow rate. As the desired volume is approached, the electronic valve gradually reduces the flow rate of the delivered water until the electronic valve 32 delivers the water at a final low flow rate. Once the electronic valve 32 has delivered approximately the desired volume, the electronic valve 32 closes.

In the exemplary embodiment, the initial low flow rate is approximately 20% of the full flow rate. In the exemplary embodiment, the flow rate is increased in approximately 20% increments until the flow rate reaches approximately full flow rate. In the exemplary embodiment, the flow rate is reduced from the full flow rate in approximately 20% decrements. In the exemplary embodiment, the final low flow rate is approximately 20% of the full flow rate.

In the exemplary embodiment, electronic valve 32 delivers water at an initial low flow rate and at each subsequent increased flow rate for a set period of time. In the exemplary embodiment, electronic valve 32 delivers water at full flow rate for a variable period of time. The variable time period is determined based in part on the desired volume and the full flow rate. In the exemplary embodiment, electronic valve 32 delivers water at each decreasing flow rate for a set period of time.

In the exemplary embodiment, electronic valve 32 delivers water at approximately the following flow rates over the following time periods:

1. at 20% of full flow rate over a first set period of time

2. 40% of full flow rate over a second set period of time

3. 60% of full flow rate in the third set time period

4. 80% of full flow rate in the fourth set time period

5. At 100% of full flow rate over a variable time period

6. 80% of full flow rate in the fifth set time period

7. 60% of full flow rate in the sixth set time period

8. 40% of full flow rate in the seventh set time period

9. At 20% of full flow rate over an eighth set time period

In an exemplary embodiment, the first set period of time, the second set period of time, the third set period of time, the fourth set period of time, the fifth set period of time, the sixth set period of time, the seventh set period of time, and the eighth set period of time are equal. In an exemplary embodiment, the first set period of time, the second set period of time, the third set period of time, the fourth set period of time, the fifth set period of time, the sixth set period of time, the seventh set period of time, and the eighth set period of time are not equal. In an exemplary embodiment, some of the first set period, the second set period, the third set period, the fourth set period, the fifth set period, the sixth set period, the seventh set period, and the eighth set period are equal, and some of the first set period, the second set period, the third set period, the fourth set period, the fifth set period, the sixth set period, the seventh set period, and the eighth set period are not equal. In an exemplary embodiment, the variable time period is determined by: the method includes calculating the volume of water delivered during a first set period of time, a second set period of time, a third set period of time, a fourth set period of time, a fifth set period of time, a sixth set period of time, a seventh set period of time, and an eighth set period of time, subtracting the calculated volume of water from the desired volume of water, and calculating the period of time required to deliver the remaining volume of water at full flow rate.

In an exemplary embodiment, where the fitment 10 or faucet 12 has a full flow rate of 1.5 Gallons Per Minute (GPM) and is to deliver a desired volume of water of 0.5 gallons, the electronic valve 32 delivers the water approximately as follows:

1. 0.0025 gallons were delivered at 0.3GPM in 0.5 seconds

2. 0.005 gallons were delivered at 0.6GPM in 0.5 seconds

3. 0.0075 gallons delivered at 0.9GPM in 0.5 second

4. Deliver 0.01 gallons at 1.2GPM in 0.5 seconds

5. Deliver 0.45 gallons at 1.5GPM in 0.3 seconds

6. Deliver 0.01 gallons at 1.2GPM in 0.5 seconds

7. 0.0075 gallons delivered at 0.9GPM in 0.5 second

8. 0.005 gallons were delivered at 0.6GPM in 0.5 seconds

9. 0.0025 gallons were delivered at 0.3GPM in 0.5 seconds

Example 2 measurement of volume-specified temperature

In an exemplary embodiment where a volume of water is delivered at a specified temperature, user input module 44 receives from the user a desired value for the volume of water to be delivered and the temperature of the water that should be delivered through fitting 10 or discharge outlet 24 of faucet 12. The user may input the desired values of temperature and volume of water to be delivered by selecting a previously saved preset or by entering the desired values via voice command or another input device. The user input module 44 sends a signal to the processor 50 indicating the desired volume and temperature. Processor 50 receives signals from user input module 44.

Fig. 6a shows an exemplary screen displayed by the user input module 44 (i.e., the mobile device 66) where the user is creating a preset with a desired value of volume and a desired value of temperature.

Fig. 6b shows an exemplary screen displayed by the user input module 44 (i.e., the voice control device 68) in which the user has provided the desired value of volume and the desired value of temperature (time of day is displayed with the desired value of volume and the desired value of temperature).

In an exemplary embodiment where user input module 44 receives from the user a desired value for the volume of water and a desired value for the temperature to be delivered through fitting 10 or discharge outlet 24 of faucet 12, user input module 44 may provide the user with the option "wait for temperature to be reached? "(see FIG. 6 a).

If the user selects the wait for temperature option or the wait for temperature option is automatically selected, the user input module 44 sends a signal to the processor 50 indicating that the water should be delivered until the temperature of the water approximately reaches the desired temperature. Once the water has approximately reached the desired temperature, the water is stopped, a notification is provided to the user, and the user input module 44 indicates to the user to trigger activation of the sensor 38 when they are ready to deliver the desired volume at the desired temperature. For example, user input module 44 displays or speaks a message to the user such as: "the water will heat up. Wait for water to stop "and" once the light has stabilized, wave hand to start water "(see fig. 7a) or" I first heat water to temperature. Waiting for the water to stop. When the lamp is stable, you can wave over the sensor to get a [ desired volume ] at a [ desired temperature ]. "(see FIG. 7 b). The notification may be visual (e.g., a lighted LED) or audible (e.g., a tone or beep). The activation sensor 38 is triggered by the user. The start sensor 38 sends a signal to the processor 50 indicating that the desired volume at the desired temperature should now be delivered. The processor 50 receives signals from the activation sensor 38 and sends signals to the electronic valve 32 to activate and deliver the desired volume at the desired temperature. As a result, once the water has been heated, the fitting 10 or faucet 12 will begin to deliver the desired volume at approximately the desired temperature of the water.

If the user does not select the option of waiting to reach temperature, user input module 44 may provide the user with the option "do water go immediately? "(see FIG. 8 a).

If the user selects the option to go out of water immediately, the user input module 44 sends a signal to the processor 50 indicating that the desired volume should be delivered immediately upon receiving the desired volume and desired temperature of water (e.g., upon selecting a preset or entering the desired volume and desired temperature). The water will be delivered at any available water temperature, but should be brought to the desired temperature as quickly as possible. Processor 50 receives signals from user input module 44 and sends signals to electronic valve 32 to activate and deliver the desired volume. As a result, the fitting 10 or faucet 12 will immediately begin delivering the desired volume of water, but will bring the temperature of the water to the desired temperature as quickly as possible.

If the user does not select the option to go out immediately (see FIG. 8a) or the user is not given the option to go out immediately, user input module 44 instructs the user to trigger activation sensor 38 when they are ready to deliver the desired volume. For example, user input module 44 displays or speaks a message to the user such as: "wave hand to start water" and "will go out [ desired volume ]. "(see fig. 5a) or" now wave over the sensor to send out the desired volume "(see fig. 5 b). The activation sensor 38 is triggered by the user. The activation sensor 38 sends a signal to the processor 50 indicating the desired volume that should now be delivered. The processor 50 receives a signal from the activation sensor 38 and sends a signal to the electronic valve 32 to activate and deliver the desired volume. As a result, the fitting 10 or tap 12 will begin delivering the desired volume of water at that time.

The electronic valve 32 receives a signal from the processor 50 to activate and deliver a desired volume and desired temperature of water. The electronic valve 32 opens and begins delivering water at an initial low flow rate. The electronic valve 32 gradually increases the flow rate of the delivered water until the electronic valve 32 delivers water at the full flow rate. As the desired volume is approached, the electronic valve gradually reduces the flow rate of the delivered water until the electronic valve 32 delivers the water at a final low flow rate. Once the electronic valve 32 has delivered approximately the desired volume, the electronic valve 32 closes.

In the exemplary embodiment, the initial low flow rate is approximately 20% of the full flow rate. In the exemplary embodiment, the flow rate is increased in approximately 20% increments until the flow rate reaches approximately full flow rate. In the exemplary embodiment, the flow rate is reduced from the full flow rate in approximately 20% increments. In the exemplary embodiment, the final low flow rate is approximately 20% of the full flow rate.

In the exemplary embodiment, electronic valve 32 delivers water at an initial low flow rate and at each subsequent increase in flow rate for a set period of time. In the exemplary embodiment, electronic valve 32 delivers water at full flow rate for a variable period of time. The variable time period is determined based in part on the desired volume and the full flow rate. In the exemplary embodiment, electronic valve 32 delivers water at each decreasing flow rate for a set period of time.

In the exemplary embodiment, electronic valve 32 delivers water at approximately the following flow rates over the following time periods:

1. at 20% of full flow rate over a first set period of time

2. 40% of full flow rate over a second set period of time

3. 60% of full flow rate in the third set time period

4. 80% of full flow rate in the fourth set time period

5. At 100% of full flow rate over a variable time period

6. 80% of full flow rate in the fifth set time period

7. 60% of full flow rate in the sixth set time period

8. 40% of full flow rate in the seventh set time period

9. At 20% of full flow rate over an eighth set time period

In an exemplary embodiment, the first set period of time, the second set period of time, the third set period of time, the fourth set period of time, the fifth set period of time, the sixth set period of time, the seventh set period of time, and the eighth set period of time are equal. In an exemplary embodiment, the first set period of time, the second set period of time, the third set period of time, the fourth set period of time, the fifth set period of time, the sixth set period of time, the seventh set period of time, and the eighth set period of time are not equal. In an exemplary embodiment, some of the first set period, the second set period, the third set period, the fourth set period, the fifth set period, the sixth set period, the seventh set period, and the eighth set period are equal, and some of the first set period, the second set period, the third set period, the fourth set period, the fifth set period, the sixth set period, the seventh set period, and the eighth set period are not equal. In an exemplary embodiment, the variable time period is determined by: the method includes calculating the volume of water delivered during a first set period of time, a second set period of time, a third set period of time, a fourth set period of time, a fifth set period of time, a sixth set period of time, a seventh set period of time, and an eighth set period of time, subtracting the calculated volume of water from the desired volume of water, and calculating the period of time required to deliver the remaining volume of water at full flow rate.
