  • Patent number: 9643280
    Abstract: A laser processing apparatus includes: a laser generator that generates a laser beam, a diffractive optical element that divides the laser beam generated by the laser generator into a plurality of sub-laser beams, and a beam gap adjustor that adjusts a gap between neighboring ones of the plurality of sub-laser beams. Therefore, by installing a diffractive optical element that divides a laser beam that is generated by the laser generator into the plurality of sub-laser beams and a beam gap adjustor to adjust a gap between a plurality of sub-laser beams, the laser processing apparatus can form a processing pattern of various resolutions in a shadow mask while improving a processing speed of the shadow mask.

  • Patent number: 9576468
    Abstract: A non-wearable Personal Emergency Response System (PERS) architecture is provided, having a synthetic aperture antenna based RF interferometer followed by two-stage human state classifier and abnormal states pattern recognition. Systems and methods transmit ultra-wide band radio frequency signals at, and receive echo signals from, the environment, process the received echo signals to yield a range-bin-based slow signal that is spatio-temporally characterized over multiple spatial range bins and multiple temporal sub-frames, respectively, and derive from the slow signal a Doppler signature and a range-time energy signature as motion characteristics of human(s) in the environment and optionally also derive location data as movement characteristics thereof. The decision process is carried out based on the instantaneous human state (local decision) followed by abnormal states patterns recognition (global decision).

    Abstract: A method and system for obtaining SAR images with reduced or eliminated surface clutter to detect subsurface targets, the method comprising the following steps: —selecting a first frequency and an incidence angle for the radar signal such that the ratio of surface backscattering to subsurface target backscattering is significantly larger for vertical polarization than for horizontal—obtaining vertically and horizontally polarized SAR images based on the same SAR path exploiting the selected first frequency and viewing angle—weighting and differencing the vertically and horizontally polarized SAR images so that the surface backscattering completely cancels between the two images and only the combination of the target backscattering components remains.
