Claim 2:
3. A mattress overload detection system comprising:
a mattress body having a top supporting surface sized and adapted to receive and support a supine individual when the surface is upwardly facing, and an opposing bottom surface, the mattress body comprising one or more polymer foam layers;
a sensor disposed at the bottom surface of the mattress body comprising an array of conductive inserts recessed in the mattress body inwardly of the bottom surface and a contact pad disposed at the bottom surface of the mattress body, each conductive insert defining an electrical switch, wherein the sensor is configured to generate a signal output when the one or more polymer foam layers has exceeded a compression threshold defined by one or more of the conductive inserts traveling into electrical communication with the contact pad to activate the corresponding switch;
wherein the sensor further comprises a processor configured to receive the signal output indicative of activation of the switches to generate a mattress overload alarm signal therefrom; and,
wherein the processor generates the mattress overload alarm signal only if a predetermined number of switches is activated.
