US Patent 11974378 Methods and arrangements for false trigger prevention

A occupancy sensor device comprising an occupancy sensor to output a detection signal, the detection signal including one or more pulses, the one or more pulses comprising one or more characteristics indicative of either detection of a motion or detection of a disturbance; a controller coupled with the sensor to receive the detection signal, the controller programmed to compare the one or more characteristics of the one or more pulses against a predetermined characteristic threshold, and based on the comparison, determine whether the one or more pulses indicate detection of the motion or detection of the disturbance. A machine readable-medium to comprise code for the controller. And, a device comprising an occupancy sensor and a vibration sensor to correlate vibrations with an output from the occupancy sensor to prevent false triggers.
