Abstract
An ultrasonic sensing system includes an ultrasonic transmitter, an ultrasonic receiver, a processor and a memory subsystem. The transmitter is positioned to transmit an ultrasonic signal into a predetermined volume. The receiver is positioned to receive a composite signal from the predetermined volume. The processor is coupled to the transmitter, the receiver and the memory subsystem. The memory subsystem stores code that when executed by the processor instructs the processor to perform a number of steps to determine whether an occupant is present in the predetermined volume and whether the detected occupant has a respiration rate.
