Multi-format,binary code symbol for non-linear strain measurement
First Claim
1. A binary code symbol for perimeter-based, non-linear strain measurement using discrete or analog deformation analysis methods, comprising:
- an outer perimeter constructed of line segments,orienting means for determining the orientation of the binary code symbol, in order to associate strain measurements with physical dimensions, wherein the orienting means is bounded at least in part by the outer perimeter, andinner and outer quiet regions for distinguishing the orienting means from its background.

Abstract
A binary code symbol for non-linear strain measurement that can be constructed in any geometric shape having a solid, continuous perimeter containing straight line segments. The symbol includes finder cells to “orient” the symbol in order to associate strain measurements with physical dimensions; and contains encoded data in “data regions” and/or “utility regions.” The data and utility regions can be distinct and separate, combined, exclusive (i.e. data regions and no utility regions, or utility regions and no data regions), or omitted. The data “density” can be varied depending upon the application, by varying the number of distinct data or utility cells present in the data regions or utility regions.
