1. A method comprising:
- generating a first signal corresponding to a first characteristic of a person support apparatus or a person supported thereon;
generating a second signal corresponding to a second characteristic of the person support apparatus or the person supported thereon;
comparing the first signal with the second signal to determine if the signal strength or the clarity of the first signal is greater than that of the second signal; and
adjusting a sensitivity of at least one sensor as a function of a difference in the signal strength or clarity between the first signal and the second signal.

Abstract
A person support apparatus includes a frame and a support surface cooperating with the frame to support a person. The person support apparatus also has a sensor coupled to one of the frame and the support surface. The sensor detects at least one characteristic associated with the person. A controller is coupled to the sensor. In response to at least one of a condition of the frame, a condition of the support surface, a position of the person, or a condition of the person, the controller operates to control the sensor by at least one of changing a gain of the sensor and changing a manner in which a signal from the sensor is filtered. In some instances, the controller turns the sensor off.
