Abstract
A patient detection system including a plurality of sensors located adjacent the support surface and each sensor having an output signal variable in response to the change detected by the sensor. A processor monitors the output signals and provide an indication of change of position of the body relative to the support surface and to individually recalibrate each of the plurality of sensors. The automatic recalibration occurs upon sensing a substantial change due to an item being moved onto the surface. The processor may also sense changes in the support surface and recalibrate each of the sensors upon a detection of change in the support surface. The processor recalibrates all of the sensors for small changes existing for a pre-determined duration and for all large changes. The processor recalibrates all of the processors for a combination of changes in less than all of the sensors from the previous calibration for each sensor.
