  • Patent number: 8146823
    Abstract: Embodiments of a method, apparatus, and article of manufacture for rapidly capturing images in an automated identification system to effectively extend one dimension of a field of view of an image system are disclosed herein. In one embodiment, the image system captures and processes multiple images of at least a portion of a surface of a component in the automated identification system in response to a trigger signal communicated from a triggering device configured to sense a location of the component. Various embodiments of the invention include multiple sources for capturing images, and/or multiple user-specified schemas for effectively extending the field of view of the image system along the axis of component travel in the automated identification system.
    Type: Grant

  • Patent number: 6506620
    Abstract: The present invention provides a micromechanical or microoptomechanical structure produced by a process comprising defining the structure in a single-crystal silicon layer separated by an insulator layer from a substrate layer; selectively etching the single crystal silicon layer; depositing and etching a polysilicon layer on the insulator layer, with remaining polysilicon forming mechanical elements of the structure; metalizing a backside of the structure; and releasing the formed structure.

  • Patent number: 6105869
    Abstract: A device and method for uniformly illuminating bar codes and two dimensional symbologies. An illumination source is mounted within the device to flood an area congruent with the field of view of the imaging optics with light to be reflected off of a code symbol. The imaging optics collects the reflected illumination received back through the window and images the same on a detector focal plane. An array of solid state light-emitting diodes are disposed adjacent to the imaging optics and a diffuser is placed between the emitters and the device window for illumination source. The emitters and diffusers are spatially arranged so as to cause homogenous distribution of light energy beyond the window and congruent with the field of view of the imaging optics.
