| Title of Invention | PASSIVE SENSORS FOR AUTOMATIC FAUCETS AND BATHROOM FLUSHERS |
|---|---|
| Abstract | This invention relates to a passive optical sensor includes a light detector sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets (10, 10A, 10B 10C) or automatic bathroom flushers (100, 100A). The pasive optical sensors provide signals to flow controllers, including control electronisc (400) and flow valves (38, 140) and require only very small amounts of electeical power for sensing users of bathroom faciliteis, and thus enable battery operation for many years. To control on ambient light, the controller executes bovel algorithms (600, 900). |
