  • Apparatus and method for controlling a patient positioned upon a cushion
    Patent number: 6145142
    Abstract: The present invention details a pressurizable mattress. The mattress has at least one inflatable cushion having a pair of sides, and at least one set of an electromagnetic energy emitting device and an electromagnetic energy receiving device. The electromagnetic energy emitting device, when operating, illuminates the interior of the inflatable cushion. The electromagnetic energy receiving device collects the illuminating energy. The operation of the mattress requires a means for measuring the optical aperture of the inflatable cushion. The measuring means determines the optical aperture of the inflatable cushion by measuring the quantity of illuminating energy collected by the electromagnetic energy receiving device when the electromagnetic energy emitting device illuminates the interior of the inflatable cushion.
