High density, rectangular binary code symbol
First Claim
1. A rectangular binary code symbol for non-linear strain measurement, comprising:
- a solid, continuous outer perimeter;
first and second data regions along adjacent sides of the perimeter, each data region comprising at least two rows, each row comprising 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 two rows, each row comprising a plurality of utility cells of alternating appearance;
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.

Abstract
A binary code symbol for non-linear strain measurement designed specifically for perimeter-based deformation and strain analysis. The symbol is rectangular with a continuous outer perimeter, two data regions along adjacent sides of the rectangle and a utility region adjacent each side opposite the data regions. Each data region is made up of at least two rows, each of which is made up of a number of data cells, and each utility region is made up of at least two rows, each of which is made up of utility cells with alternating appearance. There are at least two distinct finder cells on opposite corners of the rectangle, which can be used to orient the symbol. A non-linear strain gage for measuring the strain on an object under load in accordance includes a target, a sensor, and a computer, wherein the target is a binary code symbol.
