    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 brightness of the illuminated pixels is enhanced by combining constituent laser beams of the same wavelength. The contrast of the illuminated pixels is improved by sweeping a composite beam across a polarized screen, and by making the polarizations of all the constituent laser beams of the composite beam the same.

    摘要: An integrated optical communication and barcode scanning module suitable for use with portable electronic devices is provided. In a first mode of operation the module functions as an Infrared Data Association (IrDA) compatible communications interface. In a second mode of operation, IrDA communications is disabled, and the module functions as a barcode scanner. The module may be switched back and forth between the two modes of operation or operated simultaneously.

    摘要: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for sweeping a composite laser beam as a pattern of linear scan lines on a planar projection surface and for causing selected pixels arranged along each linear scan line to be illuminated to produce an image of high quality and in color.

    摘要: An apparatus for, and method of, imaging printed and electronic codes associated with transactions or objects to be processed, support a window on a housing, illuminate the codes through the window with illumination light from an energizable illumination system, capture return illumination light from the illuminated codes through the window with an array of light sensors looking at a field of view of a solid-state, exposable imager, and process the captured return illumination light. A printed code is read by exposing the imager for a first exposure time and by also energizing the illumination system during the first exposure time. An electronic code is read by exposing the imager for a second exposure time that is longer than the first exposure time and by also deenergizing the illumination system during the second exposure time.
