Abstract: The invention is a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics. In case of inspection of carry-on baggage a combination of computer-aided x-ray transmission imaging and x-ray diffraction analysis is used to screen; confirm and localize threats. The x-ray transmission is used to segregate dense baggage and cargo which are inspected by x-ray backscatter imaging to identify suspicious objects. All suspicious objects are carefully analyzed by x-ray diffraction. In another embodiment a slow processing system uses diffraction for identification of threats and x-ray radiography for localization of the objects. In case of drugs concealed in compartments aboard marine vessels or air crafts a hand-held x-ray system is disclosed which can be used in three modes of operation: x-ray transmission, x-ray backscatter, or x-ray diffraction dependent on the architecture of the compartment.

Abstract: A computer-aided geographic system highlights a specified area of a map based on operator input. In a preferred embodiment, a voice recognition system receives the operator input in voice form and determines the area to be highlighted. In the preferred form, the map used is a globe, and computerized controls turn and tilt the globe in response to the voice command so that one or more spotlights inside the globe illuminate the area of interest. Information related to the geographic location selected may be retrieved and simultaneously displayed on a computer monitor, video screen, slide screen, and/or narrated by synthesized voice.
