1. A 3-D code comprising:
- a plurality of apertures formed within a substrate, wherein;
each aperture comprises a unique position in the 3-D code relative to each of the other apertures;
each aperture comprises a depth, wherein at least one aperture has a depth that is different from at least one other aperture'"'"'s depth;
at least one of said plurality of apertures includes a first geometric shape; and
said at least one of said plurality of apertures includes an encoding geometric shape formed on a bottom surface of said at least one aperture; and
the encoding geometric shape encodes information.

Abstract
Systems and methods related to three-dimensional coding are disclosed. In one embodiment, a method for encoding data is described that includes generating a pattern in a substrate. The pattern includes elements and each element has one of an aperture or a protrusion. The aperture or protrusion has unique x, y coordinates within the pattern. The method also includes varying a depth of at least one element. The varied depth encodes data.

11. A method of reading a 3-D code in a substrate, the substrate including a surface, said method comprising:
-
determining a relative location of a reader and a device having a 3-D code; orienting the reader relative to the device to enable reading of the 3-D code; obtaining an image of the 3-D code; processing the image to determine a relative location of each element of the 3-D code; and determining a depth of each element of the 3-D code, said depth extending into said substrate below said surface, at least one element of the 3-D code including a different depth from a second element of the 3-D code, said different depth comprising encoded data;
whereinthe 3-D code forms part of a microperforated portion of a housing on an electronic device. - View Dependent Claims (12)
