  • PROXIMITY DETECTOR INCLUDING ANTI-FALSING MECHANISM
    Publication number: 20120162636
    Abstract: A proximity detector transmits light to an object near the proximity detector, thus providing transmitted light. A photo-sensor in the proximity detector receives transmitted light reflected by the object. The proximity detector tests the transmitted light reflected by the object to determine if the reflected light exceeds a predetermined brightness threshold value to provide preliminary object detection. The proximity detector confirms object detection by further testing ambient light received by the photo-sensor to determine if there is a substantial decrease in the amount of ambient light detected by the photo-sensor as the distance between the object and the proximity detector decreases.
