Abstract for Syntactic Landmine Detector.  Disclosed is a Syntactic Landmine Detector. The syntactic landmine detector processes a received signal from a ground penetrating RADAR which contains at least one spatial sequence, the spatial sequence containing relative spatial information locating impedance discontinuities. The spatial sequence is then associated with at least one physical characteristic of a landmine.

Abstract for (Pre-Shot Detection of Weapons Utilizing Resonant) Cavity Detection. 
An apparatus for detecting a cavity comprising a signal receiver, a signal analyzer and a threshold excedent determination processor.
  The signal receiver receives a reflected signal resulting from an interaction of multi-frequency irradiating signal(s) with at least one cavity.  The irradiating signal may include an electromagnetic or acoustic signal above a cavity dependent cutoff frequency with a randomized spectral component.  The signal analyzer computes cavity detecting statistic(s) of the reflected signal.  The cavity detecting statistic(s) may include an autocorrelation function.  The autocorrelation function may be a Fourier transform of the power spectral density of the reflected signal.  The threshold excedent determination processor generates a notification when cavity detecting statistic(s) exceed a threshold.  The threshold may include a multi-variable function.  The cavity may be the bore of a weapon.  The apparatus may be configured to determine the bearing from the cavity to the apparatus.

Abstract for Egocentric Display.  An egocentric display that corresponds to a multidimensional frame of reference. The multidimensional frame of reference may include an ego center, a nadir below the ego center, and a zenith above the ego center. The egocentric display includes a center point, an inner concentric circle and an outer concentric circle. The center point represents the nadir. The inner concentric circle is centered about the center point and represents a horizon plane that is perpendicular to a zenith-nadir line that passes through the zenith, the ego center, and the nadir. The outer concentric circle that represents the zenith should have a radius larger that the inner concentric circle and should also be centered about the center point.

Abstract for Syntactic Signal Processor and Pattern Recognizer.  A pattern recognizer includes a sequential data extractor, a data pairer, and a recognition engine. The sequential data extractor extracts a region of measured data obtained from a measuring device. The measuring device is preferably capable of detecting changes in impedance. The measured data should contain position information of the changes in impedance. The data pairer associates the region of measured data with a priori pattern data that contains expected positions of the changes in impedance. The recognition engine decides whether the associated region of measured data and the a priori pattern data differ within predetermined criteria, the predetermined criteria including: non-expected impedance changes; excessive dither; and missing impedance changes.
