Description
CONCENTRIC-RING CIRCULAR BAR CODE
CROSS-REFERENCE TO RELATED APPLICATIONS The present patent application is based on, and claims priority from, U.S. provisional Application No. 60/564,939, filed April 26, 2004, which is incoiporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION 1. Field of the Invention 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.
2. Related Art 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). The need to store greater amounts of information in a compact symbol gave rise to two-dimensional (or 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. Of the 2D bar codes listed above, only the 3-DI code (described in U.S. Patent No. 5,554,841 assigned to Lynn Ltd.) is based on a circular geometry. 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. While a variety of bar code configurations exist today, the inventor and his assignee (Direct Measurement Inc.) have identified a need for a high-data capacity circular bar code with certain geometric properties not presently available in existing bar code configurations. It is to the solution of these and other problems that the present invention is directed.
SUMMARY OF THE INVENTION It is accordingly a primary object of the present invention to provide a high- data capacity circular bar code with certain geometric properties not presently available in existing bar code configurations. This and other object of the invention are achieved by 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. In one aspect of the invention, 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.
In another aspect of the invention, the locator ring can be either inside or outside of the at least one data ring. In still another aspect of the invention, 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." In still another aspect of the invention, 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.
Other objects, features, and advantages of the present invention will be apparent to those skilled in the art upon a reading of this specification including the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In describing preferred embodiments of the present invention illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. The present invention is directed to a circular bar code configuration comprising concentric circular rings. A generic example 100 is shown in FIGURE 1. The concentric-ring circular bar code 100 is made-up of a locator ring 102, a locator cell 104, and one or more data rings 106. Each locator ring 102 and data ring 106 is circular and has a finite width. All rings 102 and 106 are concentric and there is no gap or space between rings.
Data rings 106 are groups of side-by-side data cells 106a arranged in a circle. A concentric-ring circular bar code 100 can contain one or more data rings 106, The example in FIGURE 1 has two data rings 106. Each data ring 106 in a particular symbol contains the same number of data cellslOδa. The locator ring 102 is a solid color ring that aids in machine reading by conveying the location and size of the bar code 100 to the reading device. The locator cell 104 conveys the orientation of the bar code 100 to the reading device. The locator cell 104 is a break 104a in the locator ring 102 (the "locator gap") plus a single adjacent data cell 104b of the same color as the locator ring 102. The circumferential and radial dimensions of the locator cell 104 convey the data-cell size to the reading device. The bar code 100 can be arranged such that the locator ring 102 is inside of, or at a smaller diameter than the data rings 106 (referred to as "inner"). Additionally, the locator ring 102 can be outside of, or at a larger diameter than the data rings 106 (referred to as "outer"). The bar code 100 shown in FIGURE 1 is an example of the outer-locator ring geometry. Each data cell 106a is a binary storage location. That is, a data cell 106a has a value of "1" or "0." By definition, a data cell 106a shaded the same color as the locator ring 102 has a value of "1." A data cell 106a shaded the opposite color of the locator ring 102 has a value of "0." The total storage capability of a concentric-ring circular bar code depends upon the number of data rings 106, and the number of data cellsl06a per data ring. The example in FIGURE 1 has two data rings 106 and sixteen data cells 106a per ring totaling thirty-two data locations. As described above, the locator gap 104a consumes one of the data
locations, which leaves thirty-one available data cells 106a. In general, the storage capacity of a concentric-ring circular bar code is computed as follows: Capacity = ((number of data rings) x (number of data cells per ring)) - 1 "Quiet regions" are defined as circular regions 110a and 110b immediately adjacent to the extreme radii of the symbol (i.e. immediately inside and outside of the inner and outer circumferences of the symbol area). These regions 110a and 110b assist in machine reading by providing the necessary background contrast to properly locate, identify, and read bar code data. Concentric-ring circular bar codes can be formed in "positive" or "negative" color schemes. In a positive color scheme, the locator ring 102 is shaded dark, data cells 106a with value "1" are shaded dark, data cellsl06a with value "0" are shaded light, while the quiet regions are either shaded light or have a naturally light appearance. The opposite of these rules is true of negative color schemes. These schemes are depicted by example in FIGURES 2A and 2B, which illustrate positive and negative color schemes 200a and 200b of the same bar code. Some example layouts of concentric-ring circular bar codes are provided in FIGURES 3-8. FIGURES 3, 4, and 5 show layouts with an outer locator ring 102, and FIGURES 6, 7, and 8 show layouts with an inner locator ring 102. For each layout, a corresponding sample-shaded code is provided (FIGURES 3A, 4A, 5A, 6A, 7A, and 8A). In particular, FIGURES 3 and 3A illustrate a code layout 300a with an outer locator ring 102, two data rings 106, and sixty-three data cellsl06a and corresponding sample-shaded code 300b; FIGURES 4 and 4A illustrate a code layout 400a with an outer
locator ring 102, two data rings 106, and forty-seven data cellslOδa and corresponding sample-shaded code 400b; and FIGURES 5 and 5A illustrate a code layout 500a with an outer locator ring 102, two data rings 106, and thirty-one data cells 106a and coiresponding sample-shaded code 500b; FIGURES 6 and 6A illustrate a code layout 600a with an inner locator ring 102, two data rings 106, and sixty-three data cellsl06a and corresponding sample-shaded code 600b; FIGURES 7 and 7A illustrate a code layout 700a with an inner locator ring 102, two data rings 106, and forty-seven data cellsl06a and corresponding sample-shaded code 700b; and FIGURES 8 and 8A illustrate a code layout 800a with an inner locator ring 102, two data rings 106, and thirty-one data cellslOόa and corresponding sample-shaded code 800b. Modifications and variations of the above-described embodiments of the present invention are possible, as appreciated by those skilled in the art in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims and their equivalents, the invention may be practiced otherwise than as specifically described.
