Patent number: 6438776Abstract: A bed configured to support a patient having a weight comprises a frame, a patient support, and a plurality of sensors coupled between the frame and the patient support. Each of the plurality of sensors is configured to generate an analog signal in response to a portion of the weight of the patient on the patient support. The bed also comprises a circuit coupled to the plurality of sensors to receive the analog signals therefrom. The circuit includes a plurality of analog-to-digital converters, each analog-to-digital converter being coupled to one of the sensors to generate a separate digital signal for each of the plurality of sensors, and a processor coupled to the plurality of analog-to-digital converters to determine the weight of the patient on the patient support.Type: GrantFiled: May 22, 2001Date of Patent: August 27, 2002Assignee: Hill-Rom Services, Inc.Inventors: Robert J.

Patent number: 5802640Abstract: A bed comprises an inflatable mattress supported on a platform of articulable links by a support system mounted on a weigh frame. The weigh frame is supported on a base frame supported relative to a floor. A pneumatic system includes a platform-mounted blower directing air through passageways in the articulable links. An exhaust passageway parallels the pressure passageway for exhausting opposite the blower. Air flow into and out of air cells in the mattress are controlled by valves coupling the pressurized air chamber and exhaust chamber to cell ports. A connector assembly is used to couple the cells to the platform, to adjacent cells, and to tubes connected to other cells. An alternative pneumatic system includes fans distributed on the platform in association with sets of mattress cells. A footboard assembly is formed as two gates that swing out from the foot of the bed. Each gate has a storable tray that is positionable on either side of the gate.Type: GrantFiled: December 3, 1993Date of Patent: September 8, 1998Assignee: Hill-Rom, Inc.Inventors: Robert J.
