  • Patent number: 7717023
    Abstract: Apparatus and accompanying methods for the detection and subsequent destruction or disablement of Improvised Explosive Devices (IEDs) while maintaining a satisfactory level of human safety. Operationally, our inventive method and apparatus detects the IED using one or more methods including: detecting internal battery components; detecting magnetic signature(s) of the IED; detecting a characteristic energy spectrum of the IED; and/or detecting characteristic chemical signatures of the device(s). Once detected, the device may be further characterized and then subsequently deactivated and/or destroyed by a shaped pulse charge directed at the device or its power source (battery) from a safe distance.
    Type: Grant
    Filed: December 19, 2005
    Date of Patent: May 18, 2010
    Assignee: The United States of America as represented by the Secretary of the Army

  • Patent number: 7298255
    Abstract: A sensory system for determining the orientation of an object, wherein the sensory system includes a plurality of non-uniformly spaced waveguide sensors or array(s) of waveguide sensors. The non-uniformly spaced waveguide sensors are responsive to received radio frequency signals wherein the received power of the signals is dependent upon the orientation of the waveguide(s).
