Patent ID: 7979928

Claim:
A wireless apparatus for controlling water flow to a faucet fed by a water line having a hot water supply valve and a cold water supply valve, the wireless apparatus comprising: a sensor unit having a housing with a sensor for detecting and differentiating a plurality of stimuli, a manual actuation switch, and a sensor wireless communication device, the sensor unit located remote from the faucet; a wireless hot water control valve device in operative communication with the hot water valve such that the wireless hot water control valve device selectively controls the volume of hot water supplied to the water supply line; a wireless cold water control valve device in operative communication with the cold water valve such that the wireless cold water control valve device selectively controls the volume of cold water supplied to the water supply line wherein upon detection of a first stimulus of the plurality of stimuli or actuation of the manual actuation switch, a first signal is transmitted from the sensor wireless communication device to the wireless cold water control valve device thereby triggering a change in the state of the cold water supply valve and upon detection of a second stimulus of the plurality of stimuli, a second signal is transmitted from the sensor wireless communication device to the wireless hot water control valve device thereby triggering a change in the state of the hot water supply valve, wherein the rate of flow of water from the faucet is altered upon detection of a third stimulus, wherein the faucet is positioned on a vanity and the sensor unit is positioned remotely therefrom on another portion of the vanity, the sensor unit have a zone of detection above the vanity, and wherein the sensor unit wireless communication device transmission have an identification code and the wireless cold water control valve device and the wireless hot water control valve device respond only to transmission bearing the identification code.
