Abstract: The present invention provides an encoding mechanism for a medical sensor which uses a modulated signal to provide the coded data to a remote analyzer. The modulated signal could be, for instance, a pulse width modulated signal or a frequency modulated signal. This signal is amplitude independent and thus provides a significant amount of noise immunity.

Abstract: A process for fabricating an electrical connector by the steps of: providing a housing of thermoplastic material having a front surface which will constitute an exterior surface of the connector, a rear surface and an opening extending to the rear surface; installing a conductive contact member so that at least a portion of the conductive contact member is positioned in the opening; and heating a portion of the housing adjacent the rear surface while displacing the portion of the housing to a location to extend across the opening and to contact the conductive contact member, and then allowing the portion of the housing to solidify at that location. The electrical connector may initially have a through opening which extends between the front and rear surfaces and the portion of the housing which is heated will be displaced in a manner to close the opening.

Abstract: An adjustable chair includes a base, a back support, a control on the base, a seat positioned on the control and an actuator housing supported on the base. The control mounts the back for tilting movement between a fully upright position and reclined position. A seat is pivoted to the base at a front end. The seat is also connected to the base by a plurality of locking plates. The chair includes a back stop subassembly, a back or seat tension subassembly, a seat tilt subassembly and a seat depth subassembly. The actuator housing is an elongated, tubular member having concentrically mounted controls or actuators at each end. At one end of the actuator, a rotatable actuator controls back tilt tension and a concentrically mounted, push button actuator controls the back tilt or stop position.

Abstract: A calibrated scanner is disclosed. The calibrated scanner includes a sensor board with a Charge Coupled Device (CCD) having two output signals. The sensor board also includes two offset devices, a coarse offset and a fine offset, the coarse offset being connected to the two output signals, the fine offset being connected to one of the output signals. The offsets are adjusted to provide a nonclipping DC bias for the two output signals. The sensor board also includes two gain devices, one gain device being attached to each output signal. The gain devices are adjusted to balance the two output signals. After these adjustments, the saturation level of the CCD is determined. The saturation level information is then used in readjusting the gain and offset devices. After this calibration, a linear correction may be applied to the output signal of the sensor board. The linear correction is accomplished by determining dark and light values of the sensor board.
