  • Publication number: 20120118974
    Abstract: An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform.

  • Patent number: 8132731
    Abstract: A digital image capture and processing system includes a housing having an imaging window with an illumination-focusing lens structure integrated therewithin. A printed circuit (PC) board is mounted in the housing and has a front surface, a rear surface, and a light transmission aperture spatially aligned with the imaging window. An area-type image detection array is mounted on the rear surface of the PC board. A linear array of light emitting diodes (LEDs) is mounted on the front surface of the PC board, adjacent the light transmission aperture and aligned with the illumination-focusing lens structure. The LEDs produce a plurality of illumination beams which are transmitted through the illumination-focusing lens structure to generate a field of illumination that is projected within the FOV of the system. Illumination reflected and/or scattered off an object within the FOV is retransmitted through the imaging window and the light transmission aperture, and detected by the area-type image detection array.

  • Patent number: 7967209
    Abstract: A method of illuminating objects on a countertop surface using an automatically-triggered digital image capture and processing system installed thereupon, and having a single array of LEDs disposed behind the upper edge portion of its imaging window, above which a light ray blocking shroud portion is provided. During object detection, illumination and imaging operations above the countertop surface, typically at a retail point of sale (POS) station, visible illumination rays are generated by the LEDs and projected substantially within the field of view (FOV) of the system, while the light ray blocking shroud blocks a portion of illumination rays generated from the single array of LEDs and projected above and beyond the FOV of the system, and thus prevents such blocked illumination rays from striking the eyes of the system operator or nearby consumers during system operation.

  • Patent number: 7934659
    Abstract: The wireless PDT of the present invention employs a “display-on bottom” design which places the unit perfectly centered in the hand of the operator, allowing for the best possible viewing as well as providing comfortable single-handed operation. The high-resolution LCD display allows the PCT to show sharp, clear bitmap images while supporting all Windows-recognized font types and sizes. With the auto back-lit feature, the brightness adjusts automatically making the screen easy to read in all light conditions. The PDT is designed for support within the download/charger cradle of a base station which interfaces with a host system using either USB or RS232 interface. Two standard ‘AA’ or rechargeable Li-Ion batteries provide more than 100 hours of operation. In addition, the PDT comes standard with 2 MB of RAM providing enough memory to store over 100,000 records.
