Abstract: Circuitry compensating for inherent nonlinearities in the tuning voltage sensitivity of varactor tuners, thereby providing relatively constant AFC pull-in range throughout the band of operating frequencies, is shown. In both the VHF and UHF bands, the AFC system develops an error correction voltage in proportion to the tuning voltage. With respect to reception of VHF channels, a gain switching circuit operates to reduce the proportion of AFC error correction voltage developed on a High Band VHF channel, thereby compensating for increased tuning voltage sensitivity on High Band VHF. With respect to reception of UHF channels, a tuning voltage sensing circuit operates to effect an error correction voltage that is a greater proportion of the tuning voltage when the tuning voltage is above a pre-determined value corresponding to approximately channel 60.

Abstract: This invention relates to a system and method for determining velocity, direction, position, profile and confidence information of a target such as an intruder from alarms generated by the intruder passing by an array of spaced sensors. The system comprises a processor, the primary element of which is a velocity-position matrix comprising a plurality of information storage cells in the form of counters. The cells are arranged in a plurality of adjacent rows and adjacent columns corresponding to target velocity and position, respectively. Each sensor alarm is entered as a count into cells in those columns which correspond to sensor deployment and the count in each cell is shifted to the adjacent cell in the same row by auxiliary equipment at different rates for the different rows to provide a velocity determination capability. Counts are subtracted from the cells in the columns corresponding to sensor locations when no alarm is given by the particular sensor.

Abstract: This invention concerns a circuit which decreases the time required for certain phase-locked loops to pull in, that is, the time for the frequency of the oscillator which the loop controls to go from some initial error to some specified smaller error. The circuit is utilized with a loop employing an integrating element in the loop filter in conjunction with a logic circuit for indicating out-of-lock condition plus the sign of the frequency error and utilizes a source of direct current (DC) which is connected to the loop filter so as to increase the rate of change of the correction signal to the controlled oscillator and thereby speed-up tuning of the oscillator to the desired frequency.

Abstract: Arc detection and control apparatus for a high power high voltage gas laser with a constant current power supply comprises a circuit responsive to changes in voltage across the laser electrodes for disconnecting the power supply when the voltage change exceeds a predetermined limit. The circuit monitors a small proportional value of the interelectrode voltage through an optical coupler and has a multiplier circuit for converting detected voltage changes and the differential thereof into pulses with a constant amplitude for fixed percentage changes of the electrode voltage and into pulses with increasing amplitudes for proportionally greater electrode voltage changes. This circuit normalizes and filters the resultant pulses and permits them to be compared to a reference voltage in a comparator circuit. When the pulse amplitude exceeds the value of the reference voltage a control apparatus is actuated which disconnects the power supply from the laser electrodes.
