  • Patent number: 4142116
    Abstract: A multi-channel adaptive threshold circuit usable to extract affirmative detection impulses from a plurality of detection circuits each having a different background noise level. The circuit comprises a plurality of analogous detection circuits whose outputs are coupled in parallel between a threshold circuit and threshold activation device such as a switch which grounds all outputs when in the ON position. The input to each detection circuit, which is a composite of sporadic affirmative return pulses and continuous background noise, is passed through a unidirectional conducting device, such as a base-to-emitter junction of a transistor, to charge a capacitor to a value which is a function of the continuous background noise. When the threshold activation device is turned off, the output plate of the capacitor of each detection circuit is applied to a fixed threshold circuit.

  • Patent number: 4140363
    Abstract: Apparatus for searching a large field of view to detect a modulated optical signal source utilizing an optical detector having a field of view capability less than the total field of view sought to be searched. A constant drive motor is coupled to a geneva five slot single pin mechanism which is fixed to a drum rotably mounted to a housing. A detector and associated focusing optics are positioned at the bottom of the housing with a housing window positioned on one side of the housing. Five reflective surfaces are positioned around the circumference of the drum so that the geneva mechanism intermittently rotates the drum to sequentially position each reflective surface to reflect optical energy passing through the housing window to the detector apparatus. The reflective surfaces are positioned at the varying angles around the drum so that different segments of the total field of view sought to be searched are sequentially interrogated.

  • Patent number: 4118696
    Abstract: An analog-to-frequency converter to provide an open-loop encoder of analog signals. An analog signal is injected into a voltage-to-frequency (VFO) converter to change the analog signal to a duty cycle having an UP-time to DOWN-time ratio equal to the ratio between the input analog voltage and an externally applied precision voltage level. The duty cycle signal is then "ANDED" with a clock signal to form a VFO signal pulse train which is essentially the clock signal during the UP time of the duty cycle signal. The maximum count of a clock signal counter determines the sampling period. The VFO pulses are accumulated during the sampling period so that when the clock signal counter reaches the maximum count, the accumulated number is transferred to a storage register and the accumulator reset to zero in preparation to receive and accumulate the VFO signals of the next sample period. This transfer is made in response to signals from a time-gate generator.

  • Patent number: 4101889
    Abstract: Due to the long dwell time required for doppler processing, most doppler systems are particularly vulnerable to electronic counter measures environments (jamming). Such vulnerability manifests itself by registering numerous false alarms and by receiver saturation. The proposed system will not deviate significantly from an ideal constant false alarm rate (CFAR) device when operated in an electronic countermeasure (ECM) environment nor will its sensitivity degrade as in conventional systems.

  • Patent number: 4096450
    Abstract: An improved laser cooling system for high repetition rate lasers in which a flashlamp is cooled by conducting the heat generated in the lamp directly to a holder which is a solid thermal conductor formed by the structure of the pump cavity and in turn to a heat sink without using flowing gas or liquid in the cavity or space surrounding the flashlamp. The flashlamp is fixedly mounted on the holder with a gap or space therebetween. A thin layer of barium sulfate powder or any other suitable material (which can physically conform to the outside surface of the flashlamp envelope while providing adequate thermal conductivity between the flashlamp and the holder, and adequate optical reflectivity) is then packed in the gap between the flashlamp envelope and the holder in order to reflect light efficiently and to provide a good thermal contact between the holder and the flashlamp.
