Patents by Inventor Douglas BEUERMAN

Douglas BEUERMAN 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).

  • Vacuum variable capacitor
    Patent number: 9805873
    Abstract: A vacuum variable capacitor includes a pre-vacuum enclosure for reducing a pressure differential across the bellows. The vacuum force load on the drive system can thereby be reduced, allowing faster movement of the movable electrode, faster capacitance adjustment of the vacuum variable capacitor and longer lifetimes of the device.
    Type: Grant
    Filed: May 30, 2013
    Date of Patent: October 31, 2017
    Assignee: COMET AG
    Inventors: Mark Joachim Mildner, Roland Bieri, Mike Abrecht, Walter Bigler, Douglas Beuerman, Jack Gilmore
  • Vacuum variable capacitor
    Patent number: 9721729
    Abstract: A vacuum variable capacitor includes a pre-vacuum enclosure for reducing a pressure differential across the bellows, wherein a drive is disposed outside the enclosures of the vacuum variable capacitor. The vacuum force load on the drive system can thereby be reduced, allowing faster movement of the movable electrode, faster capacitance adjustment of the vacuum variable capacitor and longer lifetimes of the device.
