  • Patent number: 9316732
    Abstract: A walk-through screening station scans individuals to detect contraband such as a concealed weapon or improvised explosive device (IED) using ultra wideband (UWB) radar sensing and imaging systems employing wafer scale active array antennas. UWB radar and advanced imaging technology enable automated threat recognition and display for monitoring personnel. The station may scan subjects passing close to or within an aperture width of an array of radar transceivers. Direct calibration by use of reflectors positioned at known locations in the image may be used to implement scanning and imaging so close to the array. The scanning station may employ an easy-to-set-up pair of panels that may be readily deployed by security providers wherever access control—such as to a meeting place or transportation boarding—is needed. Imaging and display processing may provide an abstract display—such as a stick figure representation of anatomy—to address privacy issues and concerns.

  • Patent number: 9105964
    Abstract: A system is provided to establish and maintain a data path between a Local Area Network (LAN) that is mounted on a moving vehicle and a satellite. In combination, an antenna assembly, an Antenna Control Unit (ACU), an Inertial reference Unit (IRU), and a modem are mounted together on the moving vehicle, under the overall control of a services platform. Operationally, the IRU generates parametric values indicative of the spatial attitude and location of the moving vehicle. The ACU then uses the parametric values to aim the antenna in a direction toward the satellite. In this combination, the modem is connected with the antenna to transmit and receive data between the system and the satellite. Individually or collectively, operationally compatible components of the system (IRU, ACU, antenna and modem) can be appropriately substituted to thereby customize the system.

  • Patent number: 9035838
    Abstract: An antenna implementation comprises an electromagnetic lens and at least one electromagnetically shielding member. The electromagnetic lens is adapted to guide at least one electromagnetic signal by means of at least a variation in permittivity. The at least one electromagnetically shielding member encapsulates the electromagnetic lens partially so as to direct at least one electromagnetic signal propagating through the electromagnetic lens. The at least one electromagnetically shielding member can advantageously be part of an enclosure; said enclosure encapsulates partially the electromagnetic lens. The antenna can further comprise antenna transmission means that contain wave guides. Said waveguides can advantageously be incorporated into the enclosure. The antenna is particularly suited for implementations using Substrate Integrated Waveguide techniques. SIW techniques allow miniaturization of the antenna and offer the advantage of low energy consumption as may be required in portable devices.
