Abstract

A tool for creating mechanical stamps that produce machine-readable optical labels. The tool selects an initial element of a list of two-dimensional labels. The tool selects a pixel difference to apply to a two-dimensional label for the initial element. The tool selects a cardinality for bits in one or more bytes to encode. The tool determines whether a cardinality of a bit difference for each element compared to the initial element equals the selected bit difference cardinality. The tool determines whether a pixel difference between a two-dimensional label for each element and the two-dimensional label for the initial element equals the selected pixel difference. The tool selects one or more elements from the list of two-dimensional labels to create one or more mechanical stamps.

First claim

What is claimed is:

1 . A method for creating mechanical stamps that produce machine-readable optical labels, the method comprising:
selecting, by one or more computer processors, an initial element of a list of two-dimensional labels; selecting, by one or more computer processors, a pixel difference to apply to a two-dimensional label for the initial element; selecting, by one or more computer processors, a cardinality for bits in one or more bytes to encode; determining, by one or more computer processors, whether a cardinality of a bit difference for each element compared to the initial element equals a selected bit difference cardinality; determining, by one or more computer processors, whether a pixel difference between a two-dimensional label for each element and the two-dimensional label for the initial element equals a selected pixel difference; and selecting, by one or more computer processors, one or more elements from the list of two-dimensional labels to create one or more mechanical stamps.

2 . The method of claim 1 , wherein selecting an initial element of a list of two-dimensional labels, further comprises:
selecting, by one or more computer processors, a number of bytes to encode.

3 . The method of claim 1 , wherein selecting a pixel difference to apply to a two-dimensional label for the initial element, further comprises:
computing, by one or more computer processors, a two-dimensional label for the initial element with a corresponding error correction code.

4 . The method of claim 1 , wherein selecting a cardinality for bits in one or more bytes to encode, further comprises:
selecting, by one or more computer processors, a bit difference between the initial element and a second element in the list of two-dimensional labels, wherein selecting the bit difference includes defining a number of different bits to apply to the two-dimensional label for the initial element in a plurality of two-dimensional labels for variant elements.

5 . The method of claim 1 , the method further comprising:
responsive to a determination that cardinality of a number of bits for each element does not equal the bit difference, eliminating, by one or more computer processors, each element that does not equal a defined number of different bits.

6 . The method of claim 1 , the method further comprising:
responsive to a determination that cardinality of a number of bits for each element equals a selected number of bits to encode, computing, by one or more computer processors, a two dimensional label for each element that equals the selected number of bits to encode.

7 . The method of claim 1 , the method further comprising:
responsive to a determination that the pixel difference between the two-dimensional label for each element and the two-dimensional label for the initial element does not equal the selected pixel difference, eliminating, by one or more computer processors, each two-dimensional label for each element that does not equal the selected pixel difference.

8 . The method of claim 1 , the method further comprising:
responsive to a determination that the pixel difference between the two-dimensional label for each element and the two-dimensional label for the initial element equals the selected pixel difference, adding, by one or more computer processors, the two-dimensional label for each element that equals the selected pixel difference to the list of two-dimensional labels.

9 . The method of claim 8 , wherein adding the two-dimensional label to the list of two-dimensional labels, further comprises:
adding, by one or more computer processors, a new string to a list of strings and a corresponding two-dimensional label for each element that has an error correction code and for which a generated two-dimensional label differ from the two-dimensional label of the initial element by the selected pixel difference.

10 . The method of claim 1 , wherein selecting, by one or more computer processors, one or more elements from the list of two-dimensional labels to create one or more mechanical stamps, further comprises:
selecting, by one or more computer processors, one or more elements from the list to generate a fixed part model, such that each bit difference across a selected number of elements corresponds to a specific feature on a wheel actuating a pin that can be used for creating the one or more mechanical stamps.
