    Abstract: An ambient illumination shielding apparatus for an imaging-based scanner adapted to read direct part marking (DPM) bar codes.. The shielding apparatus includes an illumination shield extending from a housing of the scanner and extending along at least a portion of a path of travel of an aiming pattern generated by an aiming apparatus of the scanner. The shield passes illumination within a predetermined wavelength range and impedes passage of illumination. outside of the predetermined wavelength range. The predetermined- wavelength range of the shield includes a wavelength range of the aiming pattern generated by the aiming apparatus. The shielding apparatus further includes a filter disposed in proximity to an imaging system of the scanner and passing illumination within a predetermined- wavelength range to the pixel array and impeding the passage of illumination outside of the predetermined wavelength range. The predetermined wavelength range of the filter includes a wavelength range of an illumination system of the scanner.

    Abstract: Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by uniformly illuminating the markings. An illuminator is operative for emitting illumination light of greater and lesser intensity toward the indicia. A diffuser is operative for diffusing the illumination light en route to the indicia. The diffuser includes a plurality of diffusing elements adjacent the illuminator for diffusing the illumination light of greater intensity more than the illumination light of lesser intensity.

    Abstract: Methods and apparatus for providing dynamic signal processing with, in one exemplary embodiment, a fast swipe image scanner. Dynamic signal processing comprises determining the rate of motion of a dataform, for example a barcode, which is passed in front of the scanner's data collection module. Then, based on the rate of motion, applying a signal processing method to the dataform. The complexity of the selected signal processing method used to decode the dataform can be chosen based on the detected rate of motion of the dataform. In alternate embodiments two or more algorithms are processes concurrently.
