Application ID: 05690621

Base Claim:
1. A method for encoding information which can be represented by an even number of binary bits, which comprises: (a) assigning a line of a selected length to each 0-bit and a line of a different selected length to each 1-bit of said binary bits thereby establishing a line code for said even number of binary bits; (b) dividing said line code along its length into equally sized first and second segments; (c) inverting one of said segments; (d) aligning the lines of said first and second segments; and (e) disposing said aligned lines in abutting relationship along a common axis, thereby forming a line code having an odd number of lines which is uniquely representative of said even number of binary bits.

Claim 3:
3. A method as claimed in claim 1 further comprising converting different lines into equal length lines of differing width which can be optically scanned.
