  • Method and system for the detection and identification of explosives and/or contraband
    Patent number: 8463557
    Abstract: A nuclear quadrupole resonance system which senses the stimulated emission from target molecules includes in a calibration step and a stimulated emission response detection step, with the system employing clutter cancellation involving linear regression and the use of cross correlation with a series of known molecular signatures, both increasing the signal-to-noise ratio of the system.

  • USING PHASE MATCHED FILTERS FOR NQR DETECTION OF CONTINUOUS RABI TRANSITIONS
    Publication number: 20130116932
    Abstract: Nuclear quadrupole resonance measurement using two or more wire loop(s) within a space to define a portal, and driving the wire loop(s) with a baseband digital transmitter generating a chirped or stepped signal, to create a corresponding varying electromagnetic field within the portal. Coherent emissions reflected thereby are detected through a directional coupler feeding the transceiver. The detected coherent emissions are processed with a matched filter to determine presence of a target object within the portal.

  • Neuromorphic parallel processor
    Patent number: 8401297
    Abstract: A neuromorphic parallel image processing approach that has five (5) functional layers. The first performs a frequency domain transform on the image data generating multiple scales and feature based representations which are independent of orientation. The second layer is populated with feature based representations. The third layer, an object class recognizer layer, are fused using a neuromorphic parallel processor. Fusion of multimodal data can achieve high confidence, biometric recognition.

  • METHOD AND APPARATUS FOR AVOIDING PATTERN BLOCKAGE DUE TO SCATTER
    Publication number: 20130021112
    Abstract: A method and apparatus is provided for avoiding pattern blockage due to scatter from an object in which an artificial surface directs the energy from the antenna prior to arriving at a blocking structure such that either the wave fronts of the energy are linear when they arrive at the blocking structure or the phase of the energy incident on the object is adjusted such that the energy reflected from the object is in phase with energy directly from the antenna radiating elsewhere in the far field pattern, or both.

  • DUAL UHF DIPOLE QUADRAFILER HELIX ANTENNA
    Publication number: 20130009832
    Abstract: A dual purpose antenna is provided with the UHF antenna in the form of a pair of copper tubes to provide an off center fed dipole, with a pair of quadrafiler helix L1 and L2 GPS antennas stacked on top of the UHF antenna, and with the top section of the UHF dipole providing a ground plain for the GPS antenna. The antennas are fed internally by two coaxial feeds, one feeding the UHF antenna, the other passing through the UHF antenna to feed the GPS antennas. In one embodiment, a tuning coil is provided at the base of the UHF antenna by the coiling of the two coaxial feeds around a non-conductive mandrel, with copper taping placed on top of the coiled coaxial sections to provide an LC circuit to lower the resonant frequency of the UHF antenna to 225 MHz.

  • WIDE BAND EMBEDDED ARMOR ANTENNA
    Publication number: 20120293381
    Abstract: An extremely thin embedded antenna for an armor-carrying vehicle utilizes a dipole driven element to the inside of the armor plate and a parasitically-driven dipole element on top of the armor plate, with the parasitic element providing appropriate forward gain and antenna matching characteristics such that there need be no aperturing of the armor plate in order to feed the antenna. In one embodiment, the bowtie antenna elements are elongated, extended or expanded by outboard antenna sections which are spaced from the distal ends of the corresponding bowties, with a meanderline choke bridging the gap between a bowtie element and its extended portion.

  • Dispersive antenna for RFID tags
    Patent number: 8260201
    Abstract: RFID tag designs and sensors are disclosed that include a dispersive antenna and exhibit greater detection ranges relative to conventional designs. The designs include, for example a transponder having including a rectifier, a radio-frequency identification (RFID) circuit for receiving and responding to interrogation signals, and a frequency dispersion element for receiving a multi-phase input signal and creating a pulse therefrom for input to the rectifier. Frequency-dispersive elements (e.g., antennas) and compatible interrogation waveforms can be used so that the rectifying diodes receive high peak voltage levels relative to the average voltage levels.
