Abstract: A distributed pressure control system for a support surface includes a main controller including a source of pressurized air and a communication interface, and an air manifold having an air inlet coupled with the air source and a plurality of air outlets. A plurality of control modules are each attachable to a respective one of the plurality of air outlets. Each control module includes at least one valve and includes a control unit communicating with the communication interface. The control modules effect inflation and deflation of air cells in the support surface via the valves based on a signal from the communication interface.

Abstract: A bed scale system includes at least one sensor frame having structure for generating a weight signal of a curved object such as a supporting wheel on a hospital bed or the like. The sensor frame includes a pair of spaced sidewalls defining a receiving area for the curved object, a bottom surface connected between the spaced sidewalls, and a deflection tab cooperable with the bottom surface. The deflection tab is deflected relative to the spaced sidewalls upon an application of weight to the sidewalls. A strain gauge is secured to the deflection tab and outputs a weight signal corresponding to the weight of the curved object according to a deflection amount of the deflection tab. The economical system provides patient weight without requiring removal of the patient from bed.
