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.

摘要： Scanning in an electro-optical reader for reading indicia is obtained by moving one array of microlenses relative to another microlens array. An outgoing laser beam directed to indicia for reflection therefrom and/or return light reflected from the indicia is steered through a scan angle by the moving array.

摘要： An electric power generator for a projectile moving through the air is based on vibrational, rather than rotational motion. The electric power generator uses an air stream through, which the projectile is traveling typically 100-250 m/s for mortars to up to 1,500 m/s for sabot or even higher electrically fired rounds. A typical 223 rifle round after being fired has energy of over 1700 J, which is equivalent to 1700 W seconds. If a Nano computer was able to extract energy of for example 50 nanowatts during bullet flight which rarely exceeds two seconds the power needed during the flight would be only a few parts per billion of the bullet's energy. Even allowing for very inefficient extraction of power, the necessary power to operate on onboard electronic devices such as computers and sensors can be extracted from the airstream through which the projectile travels.

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 of scan lines to be illuminated to produce an image of high resolution in color. The direction of scanning of the scan lines is switched between alternate frames, and the resulting image is the superposition of successive frames integrated for viewing by the human eye.

摘要： A piezoelectric transducer is driven to mechanically oscillate a mirror at a mechanical resonant frequency with high precision despite frequency variations introduced by temperature, tolerances and ageing of components. Switches are actuated at different times in order to make the drive frequency correspond to the mechanical resonant frequency.

摘要： Electrical interference between resonant, drive and line frequencies in a drive is reduced by selecting the resonant frequency to be non-harmonically related to the drive and line frequencies. The drive is of beneficial use in a lightweight, compact image projection module operative for causing selected pixels in a raster pattern to be illuminated to produce a non-distorted image of high resolution of VGA quality in color.

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 color. The pixels are rendered symmetrical in cross-section by aligning a narrow dimension of a beam spot of a laser beam along scan lines of the raster pattern.

摘要： A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.
