Abstract

A system for predicting exit from an occupant support, includes a processor, a memory in communication with the processor, and a frame having at least one force sensor which outputs a force signal in response to force exerted thereon. The system also includes machine readable instructions stored in the memory which cause the system to perform at least the following actions when executed by the processor: 1) determine a property of the signal during an interval of time, 2) classify the property as suggesting an exit event or as not suggesting an exit event, and 3) if the property is classified as suggesting an exit event, generate a notification thereof.
