| 20090289124 | Concentric-Ring Circular Bar Code - A circular bar code includes at least one circular data ring having a plurality of data cells arranged side-by-side in a circle, a circular locator ring of 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 have a finite width, and are concentric, without any gap between adjacent rings. The locator ring can be either inside or outside of the at least one data ring. 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 circumferential and radial dimensions of the locator cell convey the data cell size to the reading device. | 11-26-2009 |
