  • Method and system for detecting objects in a detection zone using modulated means
    Patent number: 6386326
    Abstract: A system and an associated method of detecting an object in a three-dimensional field adjacent to a doorway, such as an elevator doorway, uses an array of energy emitters that emit three-dimensional energy signals into the field and an array of energy receivers that receive the energy signals reflected from the object. The signals are sampled a predetermined number of times. In one embodiment, if the lowest value sampled signal reaches a predetermined threshold, an object detection signal is generated. In an alternative embodiment, if the sampled signals are within a predetermined variance range, the object detection signal is generated. In another alternative embodiment, if a predetermined modulation code is detected within a sampled signal, the object detection signal is generated.
    Type: Grant
