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 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.
A kit for detecting a mattress overload 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 having a plurality of recesses extending inwardly therefrom, the mattress body comprising one or more polymer foam layers;
- a sensor configured to be disposed at the bottom surface of the mattress body comprising a flexible board having an array of conductive inserts retained therein defining switches, wherein the conductive inserts are configured to be received within the recesses in the bottom surface of the mattress body, and a contact pad configured to be disposed at the bottom surface of the mattress body, and
- 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 active the corresponding switch.
A sensor system for detecting a mattress overload comprising:
- a flexible membrane having an array of conductive inserts retained therein, wherein the conductive inserts are configured to be received within a plurality of recesses in a bottom surface of a mattress;
- a contact pad configured to be disposed at the bottom surface of the mattress, wherein the sensor generates a signal output when one or more polymer foam layers within the mattress has exceeded a compression threshold defined by one or more of the conductive inserts traveling into electrical communication with the contact pad while supporting a supine individual on the mattress;
- a processor configured to receive the one or more signal outputs and transmit therefrom a mattress overload alarm signal as a function of time to a display device.
