  • Patent number: 10330786
    Abstract: Various technologies for mitigating interference in stretch-processed SAR imagery are described herein. Stretch-processed SAR data is received at a computing device. The stretch-processed (or deramped) SAR data is then reramped, thereby removing frequency-variant components of narrowband interference signals in the deramped data. A frequency-domain transform is executed over the reramped data to generate a spectral characteristic of the reramped data. A spectral notch filter is applied to frequency bands corresponding to the peaks of the spectral characteristic in order to filter out the narrowband interference signals. An inverse frequency-domain transform can then be executed over the filtered spectral characteristic to return to a phase-history representation of the SAR data. The phase history resulting from the inverse frequency-domain transform is a ramped phase history, which can then be deramped prior to use in connection with generating images of the scanned scene.

  • Patent number: 10330610
    Abstract: An imaging system images near-field objects with focused microwave or terahertz radiation. Multiple antennas emit microwave or terahertz radiation, such that the radiation varies in frequency over time, illuminates a near-field object, reflects from the near-field object, and travels to a passive aperture. For example, the passive aperture may comprise a dielectric lens or a parabolic reflector. The passive aperture focuses, onto a spatial region, the microwave or terahertz radiation that reflected from the near-field object. One or more antennas take measurements, in the spatial region, of the microwave or terahertz radiation that reflected from the near-field object. A computer calculates, based on the measurements, an image of the near-field object and depth information regarding the near-field object.

  • Patent number: 9781683
    Abstract: A method and apparatus for determining transmit power limits for multiple transmitter devices is provided. The method begins when a two-dimensional area scan and a localized three-dimensional volume scan are performed for each transmitter and antenna. These two-dimensional area scans are converted to a three-dimensional full volume data using analytical estimations to determine the peak averaged SAR value, and subsequently determining the error associated with the analytical estimation. The error associated with the analytical estimation is determined by comparison with the measured value. The combined peak averaged SAR may then be determined for simultaneous transmissions of multiple transmitters with varying transmit powers by combining the scaled and analytically determined three-dimensional full volume data for each transmitter. The value is then further scaled by the worst-case conversion error for all active transmitters.

    Abstract: A surface measurement module for 3-D image acquisition of a subject-under-inspection. The module having: (a) a casing to house a pattern shifting device having a fixed-pattern optic through which light from a light source is passed, an output of the pattern shifting device being directed at a polarizing beam splitter and the polarized output of the splitter directed through a lens assembly comprising at least one lens element; (b) a reflector to direct the polarized output exiting the lens assembly, to illuminate a surface of the subject-under-inspection; (c) a scattered light illumination off the surface is directed back through the lens assembly for capture by an image sensor; and (d) the casing also housing the polarizing beam splitter, the lens assembly, and the image sensor. The output of the fixed-pattern optic comprises a multi-frequency pattern. The pattern shifting device may be a linear or rotating type.

  • Patent number: 9292741
    Abstract: The present invention provides a novel apparatus and method for mapping of urban regions. An apparatus includes the remote sensing equipment that is connected to a computer processor. The remote sensing equipment gathers imaging data about an urban region. The computer processor interprets the imaging data to generate a map of the urban region comprising representations that identify a first set of indicia representing physiographic characteristics, a second set of indicia representing different types of built forms, and a third set of indicia representing patterns of human activity associated with both the physiographic characteristics and the built forms. The map can also include a fourth set of indicia representing an intensity level that at least one of the other types of indicia occurs.

  • Patent number: 9280972
    Abstract: Embodiments that relate to converting audio inputs from an environment into text are disclosed. For example, in one disclosed embodiment a speech conversion program receives audio inputs from a microphone array of a head-mounted display device. Image data is captured from the environment, and one or more possible faces are detected from image data. Eye-tracking data is used to determine a target face on which a user is focused. A beamforming technique is applied to at least a portion of the audio inputs to identify target audio inputs that are associated with the target face. The target audio inputs are converted into text that is displayed via a transparent display of the head-mounted display device.

  • Patent number: 9261592
    Abstract: A method reconstructs a scene behind a wall by transmitting a signal through the wall into the scene. Parameters of the wall are estimated from a reflected signal. A model of a permittivity of the wall is generated using the parameters, and then the scene is reconstructed as an image from the reflected signal using the model and sparse recovery.

  • Patent number: 9254824
    Abstract: An adaptive anti-collision method for vehicles has steps of creating multiple driving patterns with each driving pattern corresponding to a vehicle speed, a safe distance and a braking distance parameter, such as longer safe distance configured for faster vehicle speed, and higher vehicle speed or shorter safe distance for different road condition, acquiring dynamic information, such as vehicle speed or acceleration, of the vehicle using sensors on the vehicle, combining the dynamic information and drivers' driving behavior to determine a driving pattern through a statistical analysis and a neural network, adjusting control parameters of the vehicle according to the driving pattern for an electronic control unit of the vehicle to issue an alert or activate a braking action according to the driving pattern. Accordingly, the anti-collision method can be adapted to different vehicle speed, road condition and drivers' driving habits for adjusting the safe distance and the braking system.
