Patents by Inventor D. Allan Roberts

D. Allan Roberts 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).

  • Multispectral active remote sensing without narrowband optical filters
    Patent number: 6697155
    Abstract: A remote platform obtaining a spectrum of one or more locations by moving the platform to sequentially illuminating the locations with different wavelengths of radiation. The different wavelengths of radiation reflected from the locations may be sequentially detected and converted into data. Spectra of the locations may be assembled from the data that was sequentially collected as the platform moved.
    Type: Grant
    Filed: April 9, 2002
    Date of Patent: February 24, 2004
    Assignee: ITT Manufacturing Enterprises, Inc.
    Inventors: Michael E. Dobbs, D. Allan Roberts
  • Trap blackbody
    Patent number: 6664553
    Abstract: An apparatus for simulating a blackbody utilizes several plates to absorb and reflect electromagnetic radiation. Electromagnetic radiation entering the apparatus from a certain view is reflected from one plate to another, until the direction of travel of the electromagnetic radiation is reversed. Each time the electromagnetic radiation is reflected, the majority of the electromagnetic radiation is absorbed resulting in a negligible amount of incoming electromagnetic radiation escaping the apparatus.
    Type: Grant

    Date of Patent: December 16, 2003
    Assignee: ITT Defense & Electronics
