  • Infrared matrix sensor with signal multiplexing
    Patent number: 5185519
    Abstract: A lead salt detector array where the output voltage of each detector is switched between a signal ground or an amplifier input virtual ground. A switching circuit communicates with each detector. The detector(s) from which it is desired to read a signal is switched to the amplifier input virtual ground.
    Type: Grant
    Filed: April 30, 1991
    Date of Patent: February 9, 1993
    Assignee: Alpha Omega Instruments Corp.

  • Infrated matrix sensor with signal multiplexing
    Patent number: 5126552
    Abstract: A lead salt detector array where the output voltage of each detector is switched between a signal ground or an amplifier input virtual ground. A switching circuit communicates with each detector. All detectors in the array are switched to a signal ground except for the detector(s) from which it is desired to read a signal. This detector is switched to the amplifier input virtual ground.

  • Dew point hygrometer with continuous balancing system
    Patent number: 4345455
    Abstract: A dew point hygrometer wherein separate reflective surfaces reflect light from separate light sources to a single light sensor. One surface is cooled to develop a coating of condensation. The other surface provides a standard to detect contamination build-up on both surfaces, and to detect variations in the operation of the single light sensor.

  • Dew point hygrometer with two cooled reflective surfaces
    Patent number: 4335597
    Abstract: A dew point hygrometer which employs two cooled reflective surfaces with one surface being held at a lower temperature than the other. The lower temperature surface provides a wet mirror to detect dew formation and the dry mirror provides a standard which may be used to compensate for contamination build up on both surfaces.
