  • Patent number: 8988303
    Abstract: An orientation independent antenna apparatus using a six sided conductive structure and triangular elements on a selected surface thereof, to provide both horizontal and vertical polarization mode feeds. In one implementation, a vertical coupling element is disposed within the structure so that four perpendicular surfaces are parasitically coupled to provide the vertical polarization mode. In other implementations, coaxial cable(s) may be used with a ferrite core and/or combiner circuits to provide the horizontal mode feed.

  • Patent number: 8912788
    Abstract: System and methods for detecting substances such as explosives via the nuclear quadrupole resonance effect. We observe that the nuclear quadrupole resonances of explosives located within a cavity portal involve continuous Rabi transitions which are nonlinear processes since stimulated emission occurs. In other words, where there are no resonances caused by the presence of an explosive, high average power and low average power measurements should be identical. However, when resonances are stimulated by the system, the difference between these two conditions can be compared to determine a correction to measurements made when a person located in the cavity has explosive material on their person, without the need for separate empty portal or elaborate calibration procedures.

  • Patent number: 8912943
    Abstract: Detection of objects such as a buried explosive device while operating from a moving platform using a radio frequency emission system having two modes. An electromagnetic wave emission and detection system operates in a first mode to locate objects of interest and in a second mode to determine if an object contains explosive materials. In the first mode, the emission and detection system preferably operates as a subwavelength focusing, wideband, superlens using a near field super gain synthetic aperture continuous wave (CW) swept radar. In the second mode the system preferably enabled after detection of an object in the first mode, uses chemical detection methods such as Nuclear Quadrupole Resonance (NQR).

  • Patent number: 8901926
    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.

  • Publication number: 20140327488
    Abstract: A multi-band whip antenna having a 30 MHz to 2 GHz bandwidth and an L-band dipole has its coverage extended up to 6 GHz by eliminating nulls and reducing VSWR problems that are cured through the utilization of a sleeve over the feedpoint of the L-band antenna. Chokes in the form of sleeves are provided at either end of the L-band dipole to shorten the L-band antenna for preventing reverse polarity currents at the L-band antenna feedpoint, with the antenna further including the use of double shielded meanderlines to provide improved performance between 410-512 MHz and in which a capacitance sleeve is added at the bottom of the L-band antenna to effectively elongate the antenna below the L-band to permit operation below 700 MHz.

  • Publication number: 20140310804
    Abstract: A touch screen, now incorporated in most smart phones, presents an effective and transparent method to incorporate continuous active user verification schemes. The projected capacitive grid structure can be used to capture enough information to verify that a valid user currently has possession of the mobile device, even while the user is not consciously engaged in an active verification interface. Further processing, such as habitual gesture recognition, can augment the process.

  • Publication number: 20140266209
    Abstract: A system that uses the nuclear quadrupole resonant effect to detect the presence of materials of interest, such as may be excited by radio frequency fields generated within a portal. Transmitted chirp signals may be processed using matching filtering and other signal processing to accurately detect the presence of such materials.

  • Publication number: 20140266503
    Abstract: Dispersive properties of a linear dispersive delay line are retained in a spiral configuration by constraining the radius of curvature depending on a desired propagation mode. The compact form factor spiral can be either a continuous spiral or a piecewise linear approximation. The spiral comprises a highly dielectric waveguide such as titanium dioxide or barium tetratitanate. Preferably, a spacer with a low dielectric constant and a microstrip are disposed on the top surface. The microstrip prevents attenuation of low frequencies, thereby increasing the operating frequency range. A second dielectric spacer and a second microstrip can be deposited on the bottom surface of the waveguide. Alternatively, the bottom surface of the waveguide can face a ground plane. The waveguide can be fed by horns or half-horns.

  • Publication number: 20140182656
    Abstract: An electromagnetic energy concentrator uses a prism and waveguide with a gap layer of uniform thickness disposed between the prism and a first surface of waveguide. Energy detectors, which may be photovoltaics or miniaturized antenna elements are disposed adjacent to and co-extensive with a second surface of the waveguide. The detectors operate in each of at least two bands; a distance between detectors operating in a given band depends on a wavelength in the given band.

  • Publication number: 20140159975
    Abstract: An compact manpack format antenna operating over a broad bandwidth. In one arrangement, the antenna is formed from a set of five hollow cylindrical conductive elements. Several cylinders provide, for example, a VHF/UHF radiator section and other cylinders form an L-band radiator section. A bottom leg of the L-band section operates as part of the VHF/UHF section via coupling between that lower L-band leg and the VHF/UHF section. This coupling arrangement reduces the required overall physical length of the antenna.
