Abstract:
1. An automatic bathroom flusher, comprising: a valve having a valve body including an inlet and an outlet and a valve seat inside said body; a valve member cooperatively arranged with said valve seat, said valve member being constructed and arranged to control water flow between said inlet and said outlet, movement of said valve member between open and closed positions being controlled by water pressure inside a pilot chamber; an external cover designed for enclosing an electronic control module comprising a sensor constructed and designed to detect a user, and a controller providing signals to initiate an actuator for controlling operation of said valve by controlling said water pressure, said controller being constructed and programmed to communicate with and control operation of said sensor and execute a target detection algorithm to detect said user, said controller being constructed to initiate an automatic flush cycle after detecting departure of said user; and a photovoltaic cell, sensitive to wavelengths of visible light, for providing electrical power to a rechargeable device and said photovoltaic cell providing a signal used by said controller as supplemental data in addition to signals from said sensor for controlling operation of said valve member based on said target detection algorithm and said supplemental data.
