EXIT DETECTION SYSTEM WITH OBSTRUCTION REACTION

Abstract

A person support apparatus includes an exit detection system having a plurality of force sensors that detect the weight of an occupant positioned on a support surface and an obstruction detection system having one or more obstruction sensors. The exit detection system issues an alarm when the occupant exits, or is about to exit, the person support apparatus. The bed exit system can react to detection of an obstacle. The distribution of weight applied to the force sensors is used to determine if the occupant is about to exit the person support apparatus. Compensation is made to the exit detection system for changes in the weight distribution that are not caused by movement of the occupant. Such changes may be due to not only movement of the person support apparatus or components thereof, but obstacles encountered by the person support apparatus or components thereof.
