  • METHOD AND APPARATUS FOR INTELLIGENTLY CONTROLLING ILLUMINATION PATTERNS PROJECTED FROM BARCODE READERS
    Publication number: 20110073652
    Abstract: A method and apparatus for intelligently controlling illumination patterns projected from barcode readers. The method includes (1) detecting a location of an object of interest with a plurality of object sensors each having a corresponding object field of view; and (2) selecting at least one illumination light source to project one or more illumination patterns in one or more predetermined directions at least based upon the location of the object determined with the plurality of object sensors.

  • FRACTIONAL DOWN-SAMPLING IN IMAGING BARCODE SCANNERS
    Publication number: 20100264219
    Abstract: A method of improving the performance of an imaging reader includes (1) illuminating a symbol by projecting illuminating light on the symbol from the imaging reader, (2) capturing return light form the symbol as pixel data over a two-dimensional field of view of a solid-state imager having a matrix of image sensors, (3) reducing the number of pixels to generate reduced pixel data, (4) transmitting the reduced pixel data to a decoding circuit.

  • Imaging reader and method with internal window reflections directed away from imager
    Patent number: 7571854
    Abstract: A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the internal reflections away from the imager to enhance reader performance.

  • Imaging reader and method with tall field of view
    Publication number: 20070175996
    Abstract: A target is illuminated with light for image capture by a solid-state imager of an imaging reader over a tall field of view having an aspect ratio whose vertical dimension is larger than its horizontal dimension during image capture.

  • One piece optical assembly for low cost optical scanner
    Patent number: 6527183
    Abstract: An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.
