  • Energetic material detector
    Patent number: 8292496
    Abstract: In one general aspect, a sample area is energized. A thermal energy status of the sample area is monitored. The thermal energy status including at least one of a radiant energy and a temperature. A thermal signature of a region included in the sample area is determined based on the thermal energy status of the region. The thermal signature is analyzed to determine whether explosive particles are included in the region.
    Type: Grant

    Date of Patent: October 23, 2012
    Assignee: L-3 Communications CyTerra Corporation
    Inventors: David H. Fine, Edward E. A. Bromberg, Sean C. Christiansen, Steven Bullock, Ravi K. Konduri, Geoffrey Solomon
  • ENERGETIC MATERIAL DETECTOR
    Publication number: 20100240140
    Abstract: A method of detecting energetic materials, such as explosives, includes energizing a sample area that contains particles of energetic materials. In the method, temperature characteristics from the sample area are monitored, and a temperature released from exothermic decomposition of the particles is detected. The method further includes analyzing the detected temperature to determine the presence of the exothermic compound which caused the decomposition.
