摘要：
One embodiment of a method of interrogating a sensor to detect the presence of moisture on an occupant support comprises the steps of A) providing a moisture responsive sensor in a surveillance zone of the occupant support, the sensor being tuned to a center frequency； B) exciting the sensor with an electromagnetic signal having a frequency approximately equal to the center frequency； C) monitoring for a center frequency response from the sensor； D) comparing the center frequency response to an expected center frequency response； and E) if the center frequency response compares favorably to an expected center frequency response, issuing a first output consistent with the favorable comparison.
