    Abstract: 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.

    Abstract: An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

    Abstract: Red, blue and green lasers respectively emit a plurality of red, blue and green laser beams having respective output powers. The beams are optically focused and collinearly arranged to form a composite beam which is swept by a pair of scan mirrors in a pattern of scan lines on a projection surface, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the composite beam to produce an image. A safety circuit detects a malfunction of at least one of the lasers and the scan mirrors, and deenergizes the at least one of the lasers and the scan mirrors upon detection of the malfunction.

    Abstract: An image projection system projects an image on aprojection screen having phosphor particles for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The phosphor particles are bound in a binding material whose index of refraction matches the index of refraction of the phosphor particles to reduce back scattering of light.

The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results.

A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.
