Patents by Inventor Lloyd L. Lewins

Lloyd L. Lewins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pseudo cross-couple for non-linear detectors
    Patent number: 5278644
    Abstract: Systems for improving the quality of video images generated by a forward-looking infrared detector array include mechanisms for dynamically adjusting the output signals from one or more non-linear detectors in such an array. These systems and methods utilize the output signals from two or more detectors adjacent to each non-linear detector to provide accurate DC restoration to the signals from such non-linear detectors.
    Type: Grant
    Filed: February 3, 1992
    Date of Patent: January 11, 1994
    Assignee: Hughes Aircraft Company

  • Image restoration and faulty sensor detection and compensation system and process
    Patent number: 5101271
    Abstract: A scene-based image restoration system, method and apparatus calculates a plurality of restoration signals to be combined with a plurality of input signals to produce resultant signals that are substantially equal during a desired time interval. These scene-based image restoration systems and methods can use DC offset signals as scene restoration signals. To enhance results, faulty sensors in the system are detected, and the input signals from them compensated to produce better video images from the signals.
