  • Optical mark reader
    Patent number: 9594937
    Abstract: Each data point within a two-dimensional code can be represented by a distribution of spots. Each spot can be made small enough to be invisible to the human eye so that the two-dimensional code can be invisible on or within transparent or nontransparent materials. The spots can be spaced at a large distance to increase the signal-to-noise ratio for an optical code reader. A code reader can be adapted to read the spots and determine the data points.
    Type: Grant
    Filed: February 24, 2015
    Date of Patent: March 14, 2017
    Assignee: Electro Scientific Industries, Inc.

  • Method and apparatus for laser processing
    Patent number: 7834293
    Abstract: A method and an apparatus for processing workpieces with a laser beam include first and second stages for holding the workpieces and first and second laser beam paths. The first workpiece is loaded upon the first stage, aligned with the first laser beam path, and processing begun. While the first workpiece is aligned in relation to the first laser beam path, the second workpiece is prepared in relation to the second laser beam path. Processing of the second workpiece is begun as soon as the laser beam is available for processing.
