Abstract
Methods and apparatus for scanning a code on or in a transparent part, the method comprising: illuminating the code to generate a projected image of the code on a projection surface spaced from the transparent part; and machine scanning the projected image.
Claims20
A method for scanning a three-dimensional code on or in a transparent part, the method comprising:
- illuminating a first side of the three-dimensional code to generate a projected image of the three-dimensional code on a projection surface spaced from the transparent part;
- machine scanning the projected image;
- illuminating a second side of the three-dimensional code to generate a second projected image of the three-dimensional code on the projection surface;
- and
- machine scanning the second projected image,
- wherein the first side is encoded with static information that does not change over a lifetime of the transparent part, and the second side is encoded with information that changes over the lifetime of the transparent part.

A system for scanning a three-dimensional code on or in a transparent part, the system comprising:
- a support structure configured to support the transparent part spaced apart from a projection surface;
- and
- a light source configured to illuminate the three-dimensional code to generate a projected image of the three-dimensional code on the projection surface,
- wherein the three-dimensional code has a first side and a second side, wherein the first side is encoded with static information that does not change over a lifetime of the transparent part, and the second side is encoded with information that changes over the lifetime of the transparent part.

A method for scanning a three-dimensional code on or in a transparent part, the method comprising:
- positioning the transparent part at a spaced location between a projection surface and a light source;
- generating a first projected image of a first side of the three-dimensional code on a projection surface by illuminating the first side of the three-dimensional code using the light source;
- scanning the first projected image;
- generating a second projected image of a second side of the three-dimensional code on a projection surface by illuminating the second side of the three-dimensional code using the light source;
- scanning the second projected image,
- wherein the first side is encoded with static information that does not change over a lifetime of the transparent part, and the second side is encoded with information that changes over the lifetime of the transparent part;
- and
- decoding the information encoded on the first side and the second side of the three-dimensional code based on scanning the first projected image and the second projected image.
