Patents Examined by Stephen C. Boczinski
  • Interpolative direction determining system
    Patent number: 5410399
    Abstract: Apparatus for determining position within a beam, comprising pulses of energy transmitted in coded patterns, is achieved by processing the signals received from the beam to generate a value indicative of coarse position within the beam and by interpolation within the coarse position to generate a value resolving fine position within the coarse position.

    Assignee: Lockheed Sanders, Inc.
    Inventor: Philip M. Johnson
  • Light-operated accelerometer-type techniques
    Patent number: 5159406
    Abstract: A laser based accelerometer system uses small motion induced shifts in frequency to measure the motion of an object without contact thereof. This technique is particularly useful for determining the vibratory and velocity characteristics of objects that are otherwise inaccessible for direct motion measurement by contact sensors.
