| 20110218684 | Support Surface with Proximity Sensor and Operable in Low Power Mode - A support surface includes a pump and a plurality of air cells that are selectively inflated and deflated by the pump. A proximity sensor detects whether an object is supported on the air cells, and a control unit connected to the pump and the proximity sensor controls operation of the pump based on a signal from the proximity sensor. Battery power can be saved by operating the device in a power save mode when the proximity sensor determines that the user has left the support surface. | 09-08-2011 |
