Abstract
Disclosed herein are embodiments of three-dimensional puzzles that implement image sensors to read signatures of individual shell segments to thereby determine shell segment patterns. Also disclosed are embodiments of systems that implement RGB sensors adjacent gradient color maps to provide contactless absolute position encoders.
Claims17
A three-dimensional puzzle comprising:
- a shell having at least four faces and formed by multiple shell segments, wherein at least some of said shell segments (i) are free to move relative to adjacent shell segments and (ii) can be repositioned relative to a core within said shell,
- wherein the faces being free to rotate relative to the core about axes extending from the core toward the faces;
- a plurality of unique signatures, each located at one of said at least some of said shell segments;
- and
- at least one optical sensor configured to detect an identity and orientation of each of said at least some of said shell segments, based on said unique signatures.

A contactless absolute position encoder comprising:
- an RGB sensor affixed to a first platform, the RGB sensor having a field of view;
- and
- a color map within the field of view of the RGB sensor, the color map being affixed to a second platform;
- wherein the RGB sensor provides output indicative of the absolute position of the first platform relative to the second platform.
