摘要:
An occupant support system includes a framework, a mattress supported by the framework and having at least one bladder, an electromagnetic signal source, and an electromagnetic signal receiver. The receiver is spaced from the occupant facing side of the mattress. The signal source is configured to direct an electromagnetic signal at a target. The signal receiver is configured to receive a return signal from the target in response to the directed signal. The system also includes a processor adapted to determine immersion of the target as a function of the information content of the return signal.
