  • Patent number: 9972230
    Abstract: A sign displays moving, still, or blank images. In one aspect the sign is mounted over a roadway for viewing by occupants of vehicular traffic and pedestrians. In another aspect the sign is mounted on a vehicle. An associated sensor senses the motion of traffic in the vicinity of the sign. When traffic moves at less than a predetermined speed, the sign displays moving or changing information. At greater speeds the display on the sign is either still or blank, so as to avoid distracting nearby drivers. An electronic system provides various aspects that augment sign operation such as GPS, reception of signage information for use in particular locations, advertiser billing information based on sign usage, and collection and reporting of demographics that aid advertisers in maximizing their impact.

    Abstract: A method interlacing of images into an interlaced print file for controlling an output device. The interlacing method involves arranging a set of pixels in a line that is traverse but non-orthogonal to the longitudinal axis of a slant lens or lenticule. Each of these pixels is associated with a different frame/image, e.g., six or more frames are used in each interlaced image, with one being visible through the lens or lenticule at a time by a viewer. The slant lens interlacing method does not involve slicing each frame and the splicing these slices together. Instead, individual pixels from each frame are combined within a digital print file in a unique pattern to provide the non-orthogonal interlacing described herein (e.g., the new interlacing may be considered “matrix interlacing” or “angular-offset interlacing”), and a significantly larger amount of information is presented under each slant lens.

  • Patent number: 7724437
    Abstract: The current invention describes the method of making symmetrical radiation of extremely asymmetrical light sources, e.g. laser diode bars, using the shaper of three optical elements that preserve the brightness of the initial light source. The first element of the shaper-collimator of the fast axis-images the light source in the direction of the fast axis directly into the output plain of the shaper. The second and the third element of the shaper are the multi-segment elements that separate and optimally redistribute different beams and focus these in the direction of the slow axis. The surfaces of the shaper optical elements are described by the surfaces of the second and higher order, which enables compensation of different distortions, for instance field curvature aberration, distortion caused by the light source bending, etc. The shaper offers optimal order of secondary beam redistribution that has the least possible impact on the initial beam brightness.
