  • Search and rescue using ultraviolet radiation
    Patent number: 8441360
    Abstract: A system includes an ultraviolet c-band radiation detector to enable detection of radiation during search and rescue operations, at least a portion of the radiation including ultraviolet c-band radiation, and a stimulus generator configured to generate a stimulus in response to detected ultraviolet c-band radiation. Further embodiments may include multiple synchronized ultraviolet c-band detectors to enhance system sensitivity and facilitate detection of relatively weak radiation sources, relatively distant sources, and/or radiation scattered about an environment.
    Type: Grant
    Filed: October 12, 2010
    Date of Patent: May 14, 2013
    Assignee: Raytheon Company
    Inventors: John George Witzel, Emmanuel Menilik Negatu, Theodore John Vornbrock
  • Search and rescue using ultraviolet radiation
    Patent number: 8253576
    Abstract: A system for search and rescue includes a rescue beacon including a radiation source to emit radiation, at least a portion of which includes ultraviolet c-band radiation, and an ultraviolet c-band detector to detect the ultraviolet c-band radiation to enable locating of the rescue beacon.

  • Detection of ground-laid wire using ultraviolet C-band radiation
    Patent number: 8058875
    Abstract: A system for tracing wire includes an electrical exciter adapted to apply a voltage to a ground-laid wire to generate a corona at an outer surface of the ground laid wire, at least a portion of the corona including ultraviolet c-band radiation, and an ultraviolet c-band detector to detect the ultraviolet c-band radiation to trace at least a portion of the path of the ground-laid wire.
