AMBIENT LIGHT SENSOR TOUCH SWITCH SYSTEM AND METHOD |
摘要 |
<p>9D-HR-14540 An ambient light responsive touch switch system for producing a signal whenever ambient light impinging on a photoelectric detector at a switch location is altered relative to the ambient light sensed by a photoelectric detector at a non-switch location. The system includes means for comparing the intensity of light between the photoelectric detector at a switch location relative to the intensity of ambient light at a non-switch location and a logic system that will produce a signal when the intensity of ambient light at the switch location is altered relative to the ambient light at the non-switch location.</p> |
