SYSTEM, DEVICE AND METHOD FOR EMERGENCY PRESENCE DETECTION

摘要

A detection device and method includes a transducer array (20) located at a designated area and configured to perform an ultrasonic sweep of the area in response to a trigger event. The transducer array is capable of determining a presence of a live being (16) in the area in accordance with the ultrasonic sweep. A power supply (21) is coupled to the transducer array to provide power to the transducer array and to enable the ultrasonic sweep in a power failure. A transmitter (23) is configured to transmit a result of the ultrasonic sweep to provide a determination of the presence of a live being and the live being's location in the area to personnel responding to an event.
