Abstract
A system for signaling an overload of a foam mattress, including a foam mattress having a plurality of conductive inserts located near a bottom surface and a contact pad positioned below the bottom surface of the mattress. The system may generate an overload alarm signal as a function of receiving one or more signal outputs from the sensor over a period of time. The system may also generate an overload alarm signal as a function of receiving a plurality of individual signal outputs from a plurality of one or more conductive inserts located within a predetermined area of the sensor.
Claims22
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 each affixed to a bottom surface of a flexible retaining membrane 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.
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.
