  • 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.

  • Patent number: 7841533
    Abstract: A method of capturing processing digital images of an object, using a hand-supportable digital image capture and processing system having a trigger switch, an imaging window and a field of view (FOV) projected therethrough and onto an area-type image detection array. The method involves automatically detecting an object within the FOV, and generating a first trigger event indicative of automatic object detection within the FOV. In response to the generation of the first trigger event signal, the object targeting illumination subsystem automatically generates and projects a visible targeting illumination beam within the FOV. The human operator aligns the visible targeting illumination beam with the object in the FOV, and then manually actuates the trigger switch to generate a second trigger event signal.
