Methods and apparatus utilizing visually distinctive barcodes
First Claim
1. A method comprising the step of:
- providing an article with a bar code symbol including a bar code of linear bar code symbology, wherein the bar code comprises a sequence of first and second element types, wherein a contour defined by a bounding shape of the least area encompassing all the bar code elements has at least two non-perpendicular adjacent sides.

Abstract
Methods and apparatus utilizing visually distinctive bar code symbols are described. An article is provided with a bar code symbol including a bar code. The bar code comprises a sequence of first and second element types. The bar code symbol is made visually distinctive through one of the following features: a) at least one bar code element is not a single straight line segment; b) a contour of a bounding shape of the smallest area encompassing the bar code has at least two adjacent sides that are not perpendicular; or c) a contour of a bounding shape of the smallest area encompassing an encoding region has no side such that one end of all the bar code elements within the region touches that side. A selectable resolver is used to identify a resource for the encoded value. The resolver may access the resource to provide additional information about the article.

6. A method comprising the step of:
providing an article with a bar code symbol including a bar code of linear bar code symbology, wherein the bar code comprises a sequence of first and second element types, wherein each side of a contour defined by a polygon of the least area encompassing all the bar code elements is perpendicular to an adjacent side, wherein elements of a same type are not equidistant from each other, wherein there is no side such that one end of all the elements touches that side. - View Dependent Claims (7)

8. A method comprising the step of:
-
providing an article with a bar code symbol including a bar code of linear bar code symbology, wherein the bar code comprises one or more units of encoding, wherein at least one unit of encoding comprises a sequence of first and second element types, wherein the first and second element types have at least one of the following properties;
a) at least a portion of each element type is multi-segmented rectilinear; and
b) at least a portion of each element type has a varying curvature. - View Dependent Claims (9, 10, 11)

12. A method comprising the steps of:
-
a) scanning a bar code symbol to generate a decoded value;
b) selecting a resolver for the decoded value from a plurality of different resolvers, wherein each resolver identifies a resource for the decoded value; and
c) accessing the resource identified by the selected resolver for the decoded value. - View Dependent Claims (13, 14, 15)

16. An apparatus comprising:
-
an article of manufacture having at least one bar code symbol including a visually distinctive bar code symbol of a linear bar code symbology, wherein the visually distinctive bar code symbol further comprises a bar code having at least two element types, wherein the visually distinctive bar code is distinguished through any one of the following features;
a) at least a portion of each element type is multi-segmented rectilinear;
b) at least a portion of each element type has a varying curvature;
c) a contour of a bounding shape of the smallest area encompassing all the elements of a region of encoding of the bar code has at least two adjacent sides that are non-perpendicular; and
d) a contour of a bounding shape of the smallest area encompassing an encoding region has no side such that one end of all the bar code elements of the region touches that side. - View Dependent Claims (17, 18)

19. A method comprising the step of:
providing an article with a bar code symbol including a bar code of linear bar code symbology, wherein the bar code comprises a sequence of first and second element types, wherein each side of a contour defined by a polygon of the least area encompassing all the bar code elements is perpendicular to an adjacent side, wherein there is no side such that one end of all the elements touches that side, wherein a curvature of each element type varies along its length.
