Patents by Inventor Walter Wegener

Walter Wegener 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).

  • Process and apparatus for producing a heat image with compensation of the phase error due to scan action
    Patent number: 4238674
    Abstract: The invention contemplates a heat-detection system with optical, scanner and display components for periodic mechanical heat-scanning of a given field and for so correcting the phase of electrical signals developed in the course of scanning as to enable development of a visible display of the field without phase-shift errors which are attributable to mechanical motion of the scanner.
    Type: Grant
    Filed: February 8, 1979
    Date of Patent: December 9, 1980
    Assignee: Carl Zeiss-Stiftung
    Inventors: Gunther Kuerbitz, Walter Wegener
  • Apparatus for protecting the target of an image-producing tube from injuriously high local current densities
    Patent number: 4201931
    Abstract: The invention contemplates circuit arrangements to protect the target of an image-producing tube from injuriously high local current densities, wherein detector means is responsive to produce an electrical pulse at onset of an unacceptably high local-illumination intensity condition at the cathode. The target-cathode excitation circuit includes switch means with a resistance-changing characteristic, and so connected to respond to the electrical pulse as to rapidly reduce electron flow between the cathode and target of the tube, upon occurrence of such electrical pulse output.
