Patents by Inventor Keith Dennis Cannon

Keith Dennis Cannon 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).

  • Patent number: 7896525
    Abstract: A dichroic mixing flag for a multiparameter light is constructed that greatly improves the thermal shock tolerance of the flag and avoids having to use a more costly substrate material. The dichroic color mixing flag may be substantially circular in shape. The dichroic color mixing flag may be fixed to a mechanical component so that the flag cannot rotate with respect to the mechanical component. The dichroic color mixing flag may be fixed to the mechanical component so that the mechanical component can move the dichroic color mixing flag without moving any other dichroic color mixing flag.
    Type: Grant
    Filed: October 8, 2010
    Date of Patent: March 1, 2011
    Assignee: Barco Lighting Systems, Inc.
    Inventors: Richard S. Belliveau, Keith Dennis Cannon

  • Patent number: 7832902
    Abstract: A dichroic color mixing flag for a multiparameter light is constructed that greatly improves the thermal shock tolerance of the flag and avoids having to use a more costly quartz substrate material. The dichroic color mixing flag may be substantially circular in shape. The dichroic color mixing flag may be fixed to a mechanical component so that the flag cannot rotate with respect to the mechanical component. The dichroic color mixing flag may be fixed to the mechanical component so that the mechanical component can move the dichroic color mixing flag without moving any other dichroic color mixing flag.
