J. Kenneth Davis 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).

  • Magnetically tunable resonance frequency beam utilizing a stress-sensitive film
    Patent number: 6311557
    Abstract: Methods and apparatus for detecting particular frequencies of vibration utilize a magnetically-tunable beam element having a stress-sensitive coating and means for providing magnetic force to controllably deflect the beam element thereby changing its stiffness and its resonance frequency. It is then determined from the response of the magnetically-tunable beam element to the vibration to which the beam is exposed whether or not a particular frequency or frequencies of vibration are detected.
    Type: Grant
    Filed: September 24, 1999
    Date of Patent: November 6, 2001
    Assignee: UT-Battelle, LLC
    Inventors: J. Kenneth Davis, Thomas G. Thundat, Eric A. Wachter
  • Electrostatically tunable resonance frequency beam utilizing a stress-sensitive film
    Patent number: 6263736
    Abstract: Methods and apparatus for detecting particular frequencies of acoustic vibration utilize an electrostatically-tunable beam element having a stress-sensitive coating and means for providing electrostatic force to controllably deflect the beam element thereby changing its stiffness and its resonance frequency. It is then determined from the response of the electrostatically-tunable beam element to the acoustical vibration to which the beam is exposed whether or not a particular frequency or frequencies of acoustic vibration are detected.
