CA 2744527

A segmented circular bar code is made-up of inner and outer locator rings, one or more data rings, two large orientation cells, an even number of radially-extending gaps dividing the bar code into a corresponding number of segments, and gap locator cells straddling each radially-extending gap. Each of the locator rings and the data rings is circular and has a finite width. All rings are concentric and there is no circumferential space between the rings.

La présente invention concerne un code à barres circulaire segmenté constitué danneaux de localisation internes et externes, dun ou de plusieurs anneaux de données, de deux grandes cellules dorientation, et dun nombre pair dintervalles sétendant radialement divisant le code à barres en un nombre correspondant de segments, et des cellules de localisation despaces disposées de part et dautre de chaque intervalle sétendant radialement. Chacun des anneaux de localisation et des anneaux de données est circulaire et présente une largeur spécifique. Tous les anneaux sont concentriques et il ny a aucun espace circonférentiel entre les anneaux.
