Abstract (en)
A bed monitoring system for sensing and remotely signalling the presence or absence of a person in bed in a hospital, nursing home, or home care environment includes a sensing pad positioned above the mattress and under the person. The sensing pad has a tape switch responsive to bend or distortion of the upper surface of the mattress resulting from the weight of the person. The remote signalling of the presence or absence of the person in bed uses power line carrier transmission interfaces to send and receive "bed occupied" and "bed unoccupied" signals over the standard AC power distribution wiring. The received signals are used to provide visual and audible indications and to activate lights in the monitored room as the person arises from bed.
