  • Sonic transducer
    Patent number: 4352039
    Abstract: A sonic transducer device for vibrating windows and glass partitions in the uman ear sensitivity range to prevent the capture of conversation by placing an interfering vibration on the windows or glass partitions.
    Type: Grant
    Filed: July 25, 1980
    Date of Patent: September 28, 1982
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Jerry W. Hagood, Ralph L. Norman
  • Matrix cathode channel image device
    Patent number: 4156827
    Abstract: This device uses an oxide-metal matrix material to enable the integration either constant or pulsed image readout without the use of electron scanning. It takes advantage of a new materials's ability to serve as both a field effect emitter and a matrix channel for the emitted electrons to enable improved resolution.
    Type: Grant
    Filed: June 19, 1978
    Date of Patent: May 29, 1979

    Inventors: Joe Shelton, Jerry W. Hagood, Ralph L. Norman
  • X-ray tube
    Patent number: 4012656
    Abstract: An improved x-ray tube uses the principle that sharp points emit electrons when subjected to sufficient electric fields enabling precision x-ray emission. A new oxide-metal composite material allows a uniform array of millions of electron emitting fibers to direct electrons toward a target anode. This emitting array allows intense bombardment of the tube target without the use of a thermal emitter.
