More Information
Summary:An apparatus is provided for detecting a position of a body on a support surface of a bed. The apparatus includes at least one first sensor coupled to the bed and at least one second sensor located adjacent the support surface. The at least one first sensor has an output signal which is variable in response to changes in a weight applied to the support surface. The at least one second sensor has an output signal which is variable in response to changes in the position of the body on the support surface. The apparatus also includes a controller having inputs configured to receive the output signals from the first and second sensors. The controller is configured to monitor the output signals, to provide an indication of changes in the position of the body relative to the support surface, and to provide an indication if the body exits the support surface.
