SYMMETRICALLY ENCODED LABEL FOR AUTOMATIC LABEL READING SYSTEMS

摘要

ABSTRACT OF THE DISCLOSUREA label which is configured to carry a high density of binary codedinformation is described. The label is configured to have at least one axisof symmetry through the coded data carrying area. Coding is achieved byalternately arranged segments which have different energy reflective capabi-litics. By changing the coding on opposite sides of the axis of symmetry,an increased volume of data can be encoded onto a single label. Thus, if alabel of circular configuration is symmetrically encoded about a singlediameter each semi-circular portion of the label will carry different informa-tion and the amount of data carried in the fixed area of the label is doubledover that which can be carried by a uniformly encoded label.
