Abstract: An electronic faucet including a spout hub and a pullout wand removably coupled to the spout hub. The pullout wand is touch sensitive when docked to the spout hub, and is not touch sensitive when undocked from the spout hub.

Abstract: An apparatus and method is provided to reduce cross-talk between multiple capacitive sensors used in an electronic toilet and between multiple capacitive sensors used in an electronic faucet and an electronic soap dispenser.

Abstract: A fluid delivery device including an electronic faucet having a plurality of faucet components, and a primary capacitive sensor coupled to at least one of the faucet components and providing a primary output signal. At least one secondary capacitive sensor is located on or near an item which causes unintended effects on the output signal from the primary capacitive sensor and provides a secondary output signal. A controller determines a difference signal between the primary and secondary output signals of the primary and secondary capacitive sensors to control operation of the electronic faucet.

Abstract: An electronic faucet includes a spout assembly and a controller configured to control the flow of water through the spout assembly in response to the position of a spray head. A sensor may be positioned to detect an object in a detection zone near the faucet. The controller may disable the sensor upon the spray head being uncoupled from the spout.

Abstract: A faucet includes a logical control, a spout, a hub, a handle, and a touch control operably coupled to at least one of the spout, the hub, and the handle.

Abstract: An electronic faucet has a controller configured to selectively open and close a valve to provide fluid flow through the valve and a passageway of the faucet. The controller is programmed to selectively open and close the valve to generate a fluid flow pattern through the passageway to provide an indication to a user of a condition of the electronic faucet.

Abstract: An electronic faucet assembly includes a mixing valve and a user interface in communication with a controller. Input to the user interface illustratively causes the controller to operate in a flow control mode or a temperature control mode. In the flow control mode the mixing valve provides flow control of water at a constant temperature, while in the temperature control mode the mixing valve provides temperature control of water at a constant flow. A memory device may be secured to a faucet component to store identification data related thereto.

Abstract: A faucet for dispensing a fluid includes a spout, a pull-out spray head removably coupled to the spout and including an outlet, and a valve assembly in fluid communication with the outlet. Additionally, the faucet includes a fluid treatment assembly configured to output a treatment into the fluid. The faucet further comprises a first flow path and a second flow path.

Abstract: An electronic faucet comprises a spout having a passageway configured to conduct fluid flow through the spout, an electrically operable valve coupled to the passageway, and a single capacitive sensor coupled to a portion of the faucet. The single capacitive sensor provides both a touch sensor and a proximity sensor for the electronic faucet.

Abstract: A capacitive sensing faucet is provided. In one exemplary embodiment, the faucet includes a a faucet body hub; a spout coupled to the faucet body hub; an insulator defining a capacitive coupling between the faucet body hub and the spout, wherein the insulator is formed from an electrically conductive polymer; a capacitive sensor having an electrode coupled to the faucet body hub; and a controller coupled to the capacitive sensor, the controller determining if the spout is touched by a user based on an output signal from the capacitive sensor.

Abstract: The present disclosure relates to a solenoid valve assembly for an electronic faucet. A solenoid coil of the valve assembly may be mounted to a printed circuit board for controlling the solenoid coil. An auxiliary port may be used to control one or more additional dispensing devices.

Abstract: A water pressure controlled valve including a housing and a piston slidably received within the housing. First and second water control chambers are positioned on opposite ends of the piston and are fluidly coupled to first and second water control valves, respectively. Operation of the first and second water control valves controls water pressure in the first and second water control chambers to cause sliding movement of the piston and control water supplied to a water outlet.

Abstract: An electronic faucet (10) comprises a spout (12) having a passageway configured to conduct fluid flow through the spout, an electrically operable valve coupled to the passageway, and a single capacitive sensor (26) coupled to a portion of the faucet. The single capacitive sensor provides both a touch sensor and a proximity sensor for the electronic faucet.

Abstract: A faucet includes a spout and a manual handle that controls a manual valve located in a passageway that conducts fluid flow through the spout. An electrically operable valve is also located within the passageway. The faucet also includes an insulator located between the spout and the manual handle so that the spout is electrically isolated from the manual handle, a first touch sensor on the manual valve handle, a second touch sensor on the spout, and a capacitive sensor directly coupled to one of the first and second touch sensors and capacitively coupled to the other of the first and second touch sensors. The faucet further includes a controller coupled to the capacitive sensor. The controller monitors an output signal from the capacitive sensor to detect touching of the spout and the manual valve handle. The controller is also coupled to the electrically operable valve to control the electrically operable valve in response to the output signal from the capacitive sensor.

Abstract: A faucet (10) includes a spout (12), a passageway that conducts fluid flow through the spout (12), a electrically operable valve (22) located within the passageway, a manual valve (20) located within the passageway in series with the electrically operable valve, and a manual handle (14) that controls the manual valve (20).
