W. Randall Cason 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).

  • Backscatter inspection portal
    Patent number: 7593506
    Abstract: A system and method for inspecting an object with multiple sources of substantially coplanar penetrating radiation. Irradiation of the inspected object by the sources is temporally sequenced such that the source of detected scattered radiation is unambiguous. Thus, multiple views of the inspected object may be obtained and image quality may be enhanced.
    Type: Grant
    Filed: July 10, 2008
    Date of Patent: September 22, 2009
    Assignee: American Science and Engineering, Inc.
    Inventor: W. Randall Cason

  • Backscatter inspection portal
    Patent number: 7400701
    Abstract: A system and method for inspecting an object with multiple sources of penetrating radiation. Irradiation of the inspected object by the sources is temporally sequenced such that the source of detected scattered radiation is unambiguous. Thus, multiple views of the inspected object may be obtained and image quality may be enhanced, even in a compact geometry in which the beams are substantially coplanar.
