Abstract
An article, for example, a container, having an outer surface, at least a portion of Which is curved, and a data matrix disposed on the curved portion of the outer surface that is optically-readable to provide information associated with the article. The data matrix comprises a plurality of optically-readable elements, one or more of which has a different dimension in a direction of curvature of the outer surface than one or more other of the elements so that the plurality of elements appear to have an expected size and shape when optically viewed in a plane perpendicular to a radial line extending from the surface.
Claims20
An article having:
- an outer surface, at least a portion of which is curved;
- and
- a data matrix on said curved portion optically-readable to provide information associated with the article;
- wherein said data matrix comprises a plurality of optically-readable elements, one or more of which has a different dimension in a direction of curvature of said outer surface than one or more other of said elements so that said plurality of elements appear to have an expected size and shape when optically viewed in a plane perpendicular to a radial line extending from said surface.
A method of providing an optically-readable data matrix on a curved surface of an article for reading by an optical sensor having a sensor plane that is perpendicular to a radial line extending from said curved surface, and wherein the data matrix comprises a plurality of optically-readable elements, the method including the step of defining one or more of said elements of said matrix to have at least one dimension that is different than that of one or more other of said elements such that, when viewed in said sensor plane, said plurality of elements appear to have an expected size and shape.
The method set forth in claim ii wherein said calculating step comprises calculating said values based on a predetermined, distance between the center-points of adjacent elements, a predetermined element dimension and a diameter of the portion of said article Where said matrix is disposed.
A container having:
- an outer surface, at least a portion of which is curved;
- and
- a dot matrix on said curved portion optically-readable to provide information associated with the container;
- wherein said dot matrix comprises a plurality of optically-readable dots, one or more of which have a different horizontal radius than one or more other of said dots so that said plurality of dots appear to have an expected size and shape when optically viewed in a plane perpendicular to a radial line extending from said surface.
