    摘要: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in monochrome, color or gray scale. Edge-emitting light emitting diodes are employed, together with mutually orthogonal cylindrical lenses, to render the module with a short, slim form factor.

    摘要: An apparatus and actuator assembly for and method of projecting an image on a viewing surface either attached to the apparatus, or on a distant surface, includes sweeping a light beam along a plurality of scan lines that extend over the viewing surface, and selectively illuminating parts of the image at selected positions of the light beam on the scan lines. The viewing surface can be selected by the user by moving a panel on the housing, thereby allowing the user either option for display.

    摘要: The present invention is a guidance apparatus for movable toy vehicles that includes a track, or roadway, on which the toy vehicles move. The truck has an intersection. The intersection has a magnetic guidance mechanism for steering the toy vehicles in alternate directions through the intersection. An intersection magnetic sensing mechanism, i.e., electromagnets at the intersection and magnets in the vehicles, stops the vehicles prior to entering the intersection. Additionally, the vehicles stopped at the intersection can be actuated by a timing mechanism after passage of a predetermined time period. Furthermore, the vehicles stopped at the intersection can be actuated only after a mechanism for sensing vehicle presence in the intersection senses no vehicles in the intersection.

    摘要: A portable electo-optical scanner for reading a target bar code having a plurality of bar code elements. The portable scanner includes: a housing supporting a scanning module and an exit window. The scanning module scans the target bar code with a scanning beam and collecting reflected light returning from the bar code. The scanning module includes: a beam source emitting a scanning beam; photodetector circuitry; and a retro-reflective oscillating mirror including a light collection mirror and an integral scanning or beam directing mirror. The scanning mirror is positioned to intersect the scanning beam and direct the scanning beam through the exit window. Oscillation of the oscillating mirror causes the scanning beam to be repetitively scanned along a scanning direction across the target bar code. The light collection mirror has a field of view that follows the scanning beam. The light collection mirror receives reflected light from the target bar code and directs the reflected light toward the photodetector circuitry. The exit window comprises a lens having a positive optical power with respect to the scanning direction.
