Abstract
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.
