Patents by Inventor John Gerstenberg

John Gerstenberg 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).

  • Apparatus and method using wavefront phase measurements to determine geometrical relationships
    Patent number: 6982678
    Abstract: An apparatus includes a microwave source that produces a microwave feed beam, and a first pair of microwave sensors that each intercept and receive a portion of the microwave feed beam. The two microwave sensors are spaced apart from each other along a first-pair axis. A first phase-comparison device has as it inputs the output signals of the two microwave sensors, and as an output a first phase comparison of the first-sensor output signal and the second-sensor output signal. A first geometrical calculator has as an input the first phase comparison and as an output a geometrical relationship of the first-pair axis to an other feature. This geometrical relationship output may be used to generate a control signal that is used to alter the geometrical relationship. There may be additional microwave sensors operating in a similar manner but spaced to provide information for other geometrical axes or allow improvements in geometrical measurements.
