  • Patent number: 5631456
    Abstract: A device for controlling reflections off of and information-bearing surface is especially suitable for use in conjunction with shiny, curved surfaces containing machine-readable markings. The device includes a chamber having an interior wall and entrance and exit apertures, the entrance aperture being associated with receiving an image of the surface, and the exit aperture being associated with delivering the image of the surface to image sensing means. As the delivered image of the surface may potentially include reflections of the interior wall and exit aperture, means are provided for equalizing these reflections to minimize problems associated with sensing the image of the surface and decoding any information present.

  • Patent number: 5554841
    Abstract: A graphical symbol encoding a numerical value may be accurately read even when placed on a non-planar surface. The marker is imaged with an inventive apparatus and analyzed using an inventive method which translates the graphical image into a unique number for article identification purposes. The marker in its preferred embodiment includes an outer ring having a continuous perimeter in one or more concentric data tracks disposed within this outer ring. A timing track is used to determine angular relationships about the center of the marker. Distances between points associated with the outer ring in a particular data track are used in conjunction with these angular relationships to locate a digitally encoded visual pattern associated with a particular data track, this pattern being used to store at least a portion of a numerical code used to identify each marker-bearing article.
