  • Patent number: 8416123
    Abstract: A non-scanning radar for detecting and tracking multiple moving objects. The transmit antenna continuously illuminates the entire surveillance volume, which can even be omni-directional (hemispherical). Multiple receive antennas are employed, each covering part of the surveillance volume. Receivers are used in combination to measure angles of incidence via interferometry on objects that are resolved in range and Doppler. Very long processing times are used to compensate for the reduced antenna gain compared to any radar that scans. By continuously illuminating the surveillance volume, there is no hard limit to the number of objects that can be simultaneously tracked. The primary application for this technology is detection and tracking of such objects as bullets, artillery projectiles, mortar shells, and rockets, and determining the location of the weapon that fired them. Numerous other applications are also described.

  • Patent number: 8416127
    Abstract: A missile radar system includes a tapered radome covering a front face of a main antenna. A calibration antenna is the combination of a metal tip and an attached one or more radiating or excitation elements (monopole) on the tip. A narrow end (wedge) of the radome may aid in directing planar calibration waves toward the main antenna. The metal tip has a curved inner surface that acts, with the attached radiating element(s), as an aperture antenna. Signals are emitted from the calibration antenna back toward the front face of the main antenna. The signals pass from the tip/reflector to the front face of the main antenna through a substantially-metal-free and substantially-dielectric-free volume defined by the inner surface of the radome. The radar system allows for calibration of the antenna prior to launch and/or during flight of the missile.

  • Patent number: 8416150
    Abstract: A method and system for determining a position for an interstitial diffuser for use in a multi-component display is disclosed. Embodiments utilize a camera to capture images of visual output from one or more display screens of a multi-component display, where each image may be taken with an interstitial diffuser at a different position between the display screens. The images may be used to analyze the Moiré interference and blur of the visual output at each position of the diffuser. Moiré interference values for each diffuser position may be determined by processing images captured of the visual output while each display screen displays a white image. Blur values for each diffuser position may be determined by comparing images captured of the visual output with a reference image.

  • Patent number: 8416154
    Abstract: An apparatus and method for reducing perceived color shift as a function of viewing angle is disclosed. One embodiment is a display device that includes a color light modulator and a color filter. The filter is configured to filter wavelengths of light that would be perceived as color shifted light when reflected by the modulator at an off-axis viewing angle. Another embodiment includes a color light modulator and a color light source configured to provide light having a spectral content that lacks the wavelengths that would be perceived as color shifted light by a view of the display at an off-axis viewing angle. Another embodiment are methods of making such display devices.

  • Patent number: 8416155
    Abstract: Provided is a technique of a PDP device capable of preventing error display arising from changes in discharge characteristics in a reset period particularly due to a long-period operation. In the PDP device, a slope of a slope waveform in the reset period is changed corresponding to operation time of the PDP device. And, the slope waveform is made to have a configuration having a stepwise plurality of slopes in a predetermined reset period. For example, when the operation time becomes long, rising and falling slope waveforms of a reset waveform are configured by two steps, and a first slope thereof is made steeper than a slope before the change, and a second slope is made gentle than the slope before the change. When the operation become longer, the first slope is made further steeper and the subsequent second slope is made further gentler.

  • Patent number: 8416160
    Abstract: The present invention relates to a light emitting device for preventing a cross-talk phenomenon and a pectinated pattern. The light emitting device includes data lines, scan lines, pixels and a discharging circuit. The data lines are disposed in a first direction, and the scan lines are disposed in a second direction different from the first direction. The pixels are formed in cross areas of the data lines and the scan lines. The discharging circuit discharges at least one data line to a first discharge voltage during a first sub-discharging time of a discharging time, and changes the first discharge voltage into a second discharge voltage during a second sub-discharging time of the discharging time. The light emitting device discharges data lines to discharge voltages corresponding to cathode voltage of pixels, and so cross-talk phenomenon and pectinated pattern is not occurred in the light emitting device.
