Abstract: A method for correcting roughness of pavement wherein the steps include measuring an elevation profile of the pavement, converting the elevation profile to a roughness profile, and identifying defective segments of the roughness profile as those areas of the profile exceeding a predetermined value. A grinder is simulated over the defective segments to provide a modified elevation profile. The modified elevation profile is converted to a modified roughness profile wherein corrected defective segments are identified as defective segments in the roughness profile that exceed the predetermined value in the modified roughness profile. A grinding operation is then applied to those areas of the pavement corresponding to the defective segments.

Abstract: A device is proposed to symmetrize the radiation from one or from several linear optical emitters. The device possesses per emitter 1, 1a, 1b a cylindrical lens optical unit 2, 2a, 2b with one or more cylindrical lenses, which collimate each light beam in the y-direction, where by rotating at least one of the cylindrical lenses around the z-axis or by providing a discontinuous diffracting element, each light beam is diffracted at a different diffraction angle in the y-direction. The device additionally contains a director-collimator optical unit 3, which collimates each light beam in the x-direction and diffracts at different diffraction angles so that the main beams of the individual light beams in the x-direction converge at a specified distance from the emitter and run parallel in the y-direction. Finally, the device has a redirecting optical unit 4 which compensates for the diffraction of the light beam in the x-direction caused by the director-collimator optical unit 3.

Abstract: A tachyometric display for automotive engines comprising a display head defining a circular display field. The field comprises a plurality of concentric circular bands having a quiescent state in which all of the bands are of the same illumination level and/or color. An engine speed signal is connected through a logic circuit to change the illumination level and/or color of the bands to show speed increases. A conventional needle type speedometer indicator is combined with the display head and suitable indicia are superimposed on the display field.

Abstract: A calibration system within an optical inspection apparatus comprising a sensor, lens, fiducials, and a CPU. The CPU is configured to receive information from the sensor relating to the fiducial coordinate system and the sensor coordinate system, and the fiducials are used to determine a physical relationship between the sensor coordinates and fiducial coordinates. The calibration system has a means for calibrating the inspection system and measuring critical dimensions of an object in an accurate manner on-the-fly without additional set-up or manual calibration of the system.

Abstract: A magnetically controlled flow system having a pivotable flap with a permanent magnet at distal ends. Two coils with magnetizable cores are mounted inside the duct and positioned so as to cooperate with the permanent magnet when the flap is in either a closed or an open position. By energizing the coils, the permanent magnet is attracted to the magnetizable cores in either one of the coils, thereby actuating the flap between the closed and open positions.

Abstract: A microwave and millimeter-wave electric-field mapping system based on electro-optic sampling has been developed using micromachined Gallium Arsenide crystals mounted on gradient index lenses and single-mode optical fibers. The probes are able to detect three orthogonal polarizations of electric fields and, due to the flexibility and size of the optical fiber, can be positioned not only from the extreme near-field to the far-field regions of microwave and millimeter-wave structures, but also inside of enclosures such as waveguides and packages. A microwave electric-field-mapping system based on micromachined GaAs electro-optic sampling probes mounted on gradient index lenses and single-mode optical fibers can extract field images from the interior of an enclosed microwave cavity.
