  • Patent number: 7236120
    Abstract: A non-destructive detection method and system enables detecting a moisture patch located inside a building wall or the like. A transmitter generates a series of ultra-wideband pulses while an ultra-wideband antenna unit, preferably in the form of an antenna array including a plurality of switchable antenna pairs, directs the pulses toward the building structure so that the pulses are reflected therefrom, and receives the reflected pulses. A receiver processes the reflected pulses received by the antenna unit and produces a corresponding output. A controller controls the operation of the transmitter, receiver and antenna unit, and analyzes the output of the receiver for the presence of moisture inside of the building wall.

  • Patent number: 6785634
    Abstract: A computerized system and methods of ballistic analysis involves comparing land impressions on a plurality of control bullets and computing correlation coefficients corresponding to the land-to-land comparisons in all possible relative orientations. A set of matching coefficients is identified for each bullet pair, and the set of matching coefficients is statistically compared to a set of non-matching coefficients. The gun is concluded to be identifiable where the sets of matching coefficients and non-matching coefficients are not statistically undistinguishable. To evaluate whether an evidence bullet was fired by a suspect gun, land impressions on an evidence bullet are compared with land impressions on a plurality of control bullets in all possible relative orientations, and correlation coefficients are computed for each land-to-land comparison to identify a set of questioned coefficients.
