Abstract:
1. A passive proximity detecting system for detecting an object within a detection area and controlling a controlled device, comprising: a first sensor comprising: a second sensor comprising: a processor in communication with said first sensor and said second sensor, said processor configured to receive said first detection signal and said second detection signal, to derive a first object parameter and a second object parameter using, at least in part, a first signal level of said first detection signal from one or more of said first plurality of pixels and a second signal level of said second detection signal from one or more of said second plurality of pixels, wherein said first object parameter comprises an object distance and said second object parameter is one of the group consisting of an object size, an object position relative to said first sensor and said second sensor, an object speed, and an object direction of motion.
