James T. Woo 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).

  • Microelectromechanical liquid metal current carrying system, apparatus and method
    Patent number: 6501354
    Abstract: A microelectromechanical power relay uses mercury, or a similar liquid metal with high surface tension, as a flexible non-degrading contact mechanism. The basic systematic requirements for the micro-relay include large current carrying capacity, high speed, use of control voltages readily available in the given application, and an acceptable hold-off voltage. The preferred embodiment of the present invention includes the novel configuration of a liquid metal current carrying switching device.
    Type: Grant
    Filed: March 6, 2002
    Date of Patent: December 31, 2002
    Assignee: InterScience, Inc.
    Inventors: Adolfo O. Gutierrez, Steven C. Aceto, James T. Woo, Christopher Cormeau
