Definitions

  • the present invention relates to high data capacity bar codes. More specifically, the invention relates to a high-data capacity bar code geometry that utilizes data cells in multiple concentric circular rings.
  • Bar codes are "machine readable" markings that are used to encode and store information in a normal geometric pattern, or compressed symbol. Possibly the most familiar bar code is the one-dimensional (ID) pattern of alternating black and white bars found on labels and price tags of nearly every consumer item (commonly referred to as a universal price code or UPC).
  • ID one-dimensional
  • UPC universal price code
  • 2D bar codes Early 2D bar codes were simply multiple rows of ID bar codes. Matrix-type codes later evolved with black and white dots or squares arranged in a regular rectangular pattern. Today there are a variety of 2D bar code patterns.
  • Examples are 3-DI, Aztex, Codablock, Code 1, Code 16K, Code 49, CP Code, DataGlyph, DataMatrix, Datastrip Code, Dot Code A, Hue Code, Intacta Code, MaxiCode, MiniCode, PDF 417, QR Code, SmartCode, Snowflake Code, SuperCode, and UltraCode.
  • 3-DI code described in U.S. Patent No. 5,554,841 assigned to Lynn Ltd.
  • DMI is aware of an additional circular bar code (U.S. Patent Number 5,798,514) that utilizes lengths of opposing radial "teeth" to encode data.
  • a circular bar code comprising at least one data ring, each data ring comprising a plurality of data cells arranged side-by-side in a circle, a locator ring, the locator ring being a solid color and conveying the location and size of the bar code to a reading device, and a locator cell conveying the orientation of the bar code to the reading device.
  • the locator ring and the at least one data ring are circular, have a finite width, and are concentric, without any gap between adjacent rings.
  • the locator cell is defined by a gap in the locator ring and a single data cell located in a data ring adjacent the locator ring, the single data cell being adjacent the gap and the same color as the locator ring.
  • the circumferential and radial dimensions of the locator cell convey the data cell size to the reading device.
  • the locator ring can be either inside or outside of the at least one data ring.
  • the circular bar code can have either a positive or a negative color scheme. Each data cell is a binary storage location. A data cell of the same color as the locator ring has a value of "1" and a data cell of the opposite color as the locator ring has a value of "0.”
  • the locator ring and the at least one data ring together define a symbol area, and wherein the circular bar code further comprises inner and outer quiet regions immediately inside and outside the symbol area for providing background contrast to enable the reading device to properly locate, identify, and read data in the bar code.
  • the capacity of the circular bar code equals ((number of data rings) ' (number of data cells per ring)) - 1.

Abstract

L'invention porte sur un code-barres à anneaux concentriques comprenant: au moins un anneau de cellules de données disposées côte à côte en cercle; un anneau de localisation en aplat transférant l'emplacement et la taille du code-barres au dispositif de lecture; et une cellule de localisation transférant l'orientation du code barres au dispositif de lecture. L'anneau de localisation et le ou les anneaux de localisation ont une largeur finie et sont disposés concentriquement en ne laissant aucun espace entre deux anneaux contigus. L'anneau de localisation peut être placé à l'intérieur ou à l'extérieur du ou des anneaux de données. La cellule de localisation est délimitée par un vide dans l'anneau de localisation et par une des cellules de données de l'anneau de données contigu à l'anneau de localisation. Les dimensions de la circonférence et du rayon de la cellule de localisation permettent de transférer la taille des cellules de données au dispositif de lecture.
