Abstract

An ultrasonic killswitch system for an operator- controlled powered apparatus includes ultrasonic sensor units (110) for scanning a search area to detect the presence or absence of objects in the search area. A controller is programmed to generate a killswitch signal in response to a reading or signal from said sensor units indicative of the absence of an operator (102) within the search area, for automatically cutting off power for powered operation of the apparatus. A calibration mode uses multiple scanning operations to identify permanent and non-permanent objects within the search area, by creating a virtual map of reflective responses to ultrasonic pulses from the sensor units. Each sensor unit has a piezoelectric transmitter and a piezoelectric receiver and a single input/output cable for communication with the controller.
