Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold. The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping. In addition, infrared sensitivity is adjusted based upon an estimation of the background noise in order to minimize the occurrence of false tripping.

Abstract: An occupancy sensor is provided with a housing having an interior cavity. A switch is mounted in the interior cavity of the housing and configured for placement in the open and closed positions. A fascia cover plate may be positioned on the housing to enclose the interior cavity. The fascia cover plate has a fascia rib on an interior surface thereof. The fascia rib is arranged to interfere with the switch in the disabled state to prevent positioning of the fascia cover plate on the housing.
