Patents by Inventor Donald J. Lentz

Donald J. Lentz 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).

  • Component cooling in electronic devices
    Patent number: 6836409
    Abstract: A device for dissipating heat produced by circuitry such as the circuitry associated with an optical transponder includes a plurality of heat dissipating regions. Each heat dissipating region includes a heat sink that is thermally coupled with at least one component. Each heat sink is at least partially thermally isolated from other heat sinks to mitigate heat flow from high-power components to heat sensitive components. Further, all of the heat sinks associated with the circuit package are electrically coupled to provide electromagnetic shielding. A thermally insulative and electrically conductive gasket is employed to couple adjacent heat sinks.
    Type: Grant
    Filed: May 1, 2003
    Date of Patent: December 28, 2004
    Assignee: Nortel Networks Limited
    Inventors: Guy A. Duxbury, Balwantrei V. Mistry, Donald J. Lentz
