Patent number: 4914859Abstract: Mechanism primarily suited to automatic sliding door applications wherein at least a pair of object presence sensing detectors, preferably of the ultra-sonic transducer type are arranged to be placed in linear spaced relation to one another effective to cast sonic beams produced thereby spanning the doorway to which applied. So as to assure satisfactorily a beam path to be intercepted by an object stationary or moving in the beams, they are purposely overlapped. The door upon being operatively moved by motion sensing detectors or manual means acts at different opening positions to switch the object sensing detectors on and upon reverse closing positions switches the object sensing detectors off.Type: GrantFiled: September 23, 1988Date of Patent: April 10, 1990Assignee: Lanson Electronics, Inc.Inventors: Daniel C.

Patent number: 4916366Abstract: A horizontal deflection circuit includes a flyback transformer. A secondary winding of the flyback transformer is coupled in series with a diode switch to produce a trace rectified supply voltage that energizes a vertical deflection amplifier. The diode switch also provides switching operation in an East-West diode modulator. During, for example, service mode operation, when the vertical raster is collapsed, the trace current in the secondary winding is substantially reduced. The reduced trace current is sensed for producing a control signal that causes the peak current supplied by the diode switch to the diode modulator to be smaller than the trace current in the secondary winding. This ensures that the diode switch remains conductive throughout horizontal trace, thereby, preventing an undesirable increase in the supply voltage from occuring.Type: GrantFiled: November 21, 1988Date of Patent: April 10, 1990Assignee: Thomson Consumer Electronics, Inc.Inventors: James A. Wilber, Joseph C. Stephens

Patent number: 4906973Abstract: A walk-through metal detector comprising an array module supporting transmit and receive coil arrays. Surrounding the array module, yet not touching it, is an outer shell protecting the array module from contact. A passageway tube passes through the opening in the array module, and is supported by the outer shell, further isolating the array module from mechanical vibration. The array module has a relatively high resonant frequency; thus, vibration induced signals are higher in frequency than actual target signals and are disregarded by the detection circuitry. The metal detector also includes a bypass chute, mechanically isolated from the array module, in which metallic objects may be placed and transported to the exit of the passageway without setting any alarms. The array module supports a balanced transmit and receive coil array for insensitivity to external electromagnetic interference.Type: GrantFiled: April 29, 1988Date of Patent: March 6, 1990Assignee: White's Electronics, Inc.Inventors: James P.

Patent number: 4904950Abstract: A telemetry receiver for demodulating subcarrier frequencies is disclosed. The flexibility of the receiver permits it to decode signals from a wide variety of transmitters. In the preferred embodiment, a biomedical digital telemetry subcarrier demodulator employs microprocessor control of a variable bandpass filter and cycle counter. The bandpass of the filter is set by the microprocessor to pass frequencies at and around the center frequency of the desired subcarrier frequency. The counter is preset for the desired number of cycles. In operation, the desired subcarrier frequency is passed by the filter, through a signal shaper, and to the counter. Upon receiving the first cycle, the counter activates a timer, which measure the period of the predetermined number of cycles. The desired signal is the percentage deviation of the subcarrier period from the average subcarrier period.Type: GrantFiled: November 4, 1988Date of Patent: February 27, 1990Assignee: Medical Data Electronics, Inc.Inventors: Jay E.
