Augmented binary code symbol
First Claim
1. An augmented binary code symbol for non-linear strain measurement and perimeter-based deformation and strain analysis, comprising:
- a solid, continuous outer perimeter;
first and second data regions along adjacent sides of the perimeter, each data region comprising at least one row of a plurality of data cells, each data cell representing a single bit of binary data;
first and second utility regions along adjacent sides of the perimeter opposite the first and second data regions, each utility region comprising at least one row of a plurality of utility cells of alternating appearance, wherein the utility cells encode data in the first and second utility regions;
first and second finder cells at opposite corners of the rectangle; and
inner and outer quiet regions distinguishing the first and second data regions, the first and second utility regions, and the first and second finder cells from their background;
wherein the data cells and the utility cells have well-defined edges.

Abstract
An augmented binary code symbol (100) includes a perimeter, first and second data regions (20) along adjacent sides of the perimeter, first and second utility regions (30) along adjacent sides of the perimeter opposite the first and second data regions (20), first and second finder cells (40) at opposite comers of the rectangle, and inner and outer quiet regions distinguishing the first and second data regions, the first and second utility regions (30), and the first and second finder cells (40) from their background. Each data region and each utility region has at least one row (22) of a plurality of data cells (24) and utility cells, respectively, which encode data and have well-defined edges, enabling the number of data and utility cells to be increased, so as to increase the density of the encoded data. The data and utility cells are marked using a short wave length laser in order to create the well-defined edges.
