  • Patent number: 6438776
    Abstract: 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.

  • Patent number: 5802640
    Abstract: 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.

  • Patent number: 4679568
    Abstract: Disclosed is a preamplifier which is responsive to a physiological potential developed by a subject and operative to develop a potential suitably isolated therefrom, the preamplifier including a pair of input networks for receiving therebetween the physiological potential, a pair of operational amplifiers each connected in a unity (voltage) gain, voltage follower, configuration and each driven by a respective one of the input networks, a low resistance resistor connected between the voltage followers to directly develop from the potential a current of suitable level for directly driving an optical isolator, and an optical isolator having an input portion which is connected in the feedback path of one of the operational amplifiers so as to be driven by the current and an output portion at which the optical isolator develops the isolated potential.

  • Patent number: 4402588
    Abstract: A camera (10) has a passive display device, preferably a liquid crystal display panel (26), positioned in front of one edge of the film (24), in the path of light directed at the film from the lens and shutter assembly (12). The display is driven by a clock or other control circuit (28), also in the camera, with controls (30) on the outside of the camera so as to display the date and time, or other selected indicia, continuously, whereby light entering the camera upon taking a picture will cause the display to cast a shadow (40') of the indicia onto the film, thereby automatically to label the film. The clock circuit and display may be arranged as a retrofit device (44-50) for an existing camera. A second display (34) with identical indicia may be arranged to provide a readout in the viewfinder (20) to indicate to the photographer how the labeled photography will appear. The camera may also contain a light source (54) for illuminating the readout from the front thereof.
