An automatic faucet or tap (also hands-free faucet, touchless faucet, electronic faucet, motion sensing faucet, sensor faucet, or infrared faucet) is a faucet equipped with a proximity sensor and mechanism that opens its valve to allow water to flow in response to the presence of a hand or hands in close proximity. The faucet closes its valve again after a few seconds or when it no longer detects the presence of hands. Most automatic faucets are battery powered and incorporate an active infrared sensor to detect hand motion.
Capacitive touch on/off control for an automatic residential faucet
ActiveUS6962168B2Operating means/releasing devices for valvesServomotor componentsProximity sensorWater flow
A capacitive touch-controlled automatic faucet comprises: a spout, a magnetically latching valve, a proximity sensor, a handle, a capacitive touch-control, and a logical control. The proximity sensor is sensitive to motion of objects within a detection zone of the proximity sensor. The handle determines a water flow rate and temperature. The capacitive touch-control is positioned in the spout and generates an output signal while the touch-control is in contact with a user. The logical control receives the output signal, and toggles the magnetically latching valve when the output signal begins and ends within a period of time less than a predetermined threshold, but does not toggle the magnetically latching valve when the output signal persists for a period longer than the predetermined threshold. The faucet has a manual mode, wherein the proximity sensor is inactive, and a hands-free mode, wherein water flow is toggled in response to the proximity sensor.

A hands-free faucet comprises a proximity sensor, a logical control, a handle including a first touch control, a second touch control, and a mode indicator. The logical control has a manual mode (wherein the proximity sensor is inactive, and water flow is toggled on and off by positioning the handle) and a hands-free mode (wherein water flow is toggled on and off in response to the proximity sensor). The first touch control puts the faucet in the hands-free mode when touched by a user. The second touch control toggles the logical control between the hands-free mode and the manual mode when touched by a user. The mode indicator indicates which mode the faucet is presently in. The water flow has a temperature and a flow rate that are determined by the position of the handle.

Passive sensors and control algorithms for faucets and bathroom flushers
ActiveUS20070057215A1Operating means/releasing devices for valvesFlushing devicesControl electronicsEngineering
An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

System and method for more efficient automatic irrigation based on a large number of cheap humidity sensors and automatic faucets
InactiveUS20050133613A1Control can be done more efficiently and moreProtection worksSelf-acting watering devicesWatering devicesMechanical sensorAutomatic faucet
The present invention provides an irrigation system with cheap humidity sensors and cheap automatic faucets preferably by using at the end nodes of the system low water pressure, so that much less force is needed to open and close the local waterway and then either using simple electrical valves that do not require engines, or using for example mechanical sensors based on a bi-material of two or more materials which expand differently when they become wet, thus converting the difference of the expansion into convenient movement. Another possible variation, instead of mechanical sensors and valves, is to use for example a preferably synthetic material that tends to behave like a normal root preferably at the edge of each side channel, so that the “root” counter-balances the water supply and reaches equilibrium with it when the soil becomes wet enough, based preferably on asymmetric capillary materials.

The present invention provides an automatic faucet with a movable cam assembly for mounting the senor and sensor window inside of the faucet body. The cam has an obliquely angled surface and can be moved up against a spring to provide space for assembling the sensor inside the faucet. Once the sensor is properly positioned, the spring drives the wedge-like cam back down to apply a holding force against the sensor and the window. Back pressure against the sensor or window can be absorbed to some extend by the spring to reduce the chance of damaging the window and / or sensor from impact.

Automatic faucet with control of water temperature and water flow
InactiveUS20110133105A1Control flowOperating means/releasing devices for valvesDomestic plumbingWater flowEngineering
This disclosure presents an improved automatic faucet / sink. Conventional automatic faucets, such as are present in public locations outside of the home, such as restaurants and roadside rest-stops, allow the on / off control of water flow. Existing automatic faucets do not allow for control over temperature of the water flow. This invention will provide hygienic access to the water faucet for washing the hands since the user does not have to touch the faucet or sink for control over water flow or temperature. Control of water temperature will represent an improvement in automatic faucets.The invention disclosed here provides for the control of water temperature in automatic faucets. In one implementation this is accomplished with a distance sensor in the faucet that varies the water temperature depending on the distance of the hands under the water spout from the distance sensor. In a second implementation, a microphone with voice-recognition capabilities responds to words (e.g. hotter or colder) to vary the temperature of the water.
