  • Bar code reader including linear sensor array and hybrid camera and bar code reader
    Patent number: 7040538
    Abstract: A semiconductor detector device for detecting optical code symbols includes no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1 with a short dimension not greater than 8 microns. In a bar code reader, a sensor for detecting the field of view of the reader includes a single semiconductor device having a collection of surfaces configured as a set of no less than 256 and no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1, with a short dimension not less than 2 microns and not greater than 8 microns.

  • Imaging bar code reader with moving beam simulation
    Patent number: 6866198
    Abstract: The operating environment of a moving laser beam in a flying spot, electro-optical reader is simulated in a solid-state, sensor-based imaging reader by turning a visible line produced by a light emitting diode on and off prior to capturing a two-dimensional image of a target.
