Abstract
The illustrative embodiment of the present invention uses a tangible three-dimensional structure as a fiducial mark, which structure is, at least partially, tolerant of dimensional variations in the article. The illustrative embodiment uses three such tangible three-dimensional structures: (1) a portion of a tangible conical surface, (2) a portion of a tangible spheroidal surface, and (3) a portion of a tangible pyramidal surface.
Claims20
An article of manufacture comprising:
- a first hole in a first portion of a first material composing the article of manufacture, wherein the first hole in the first portion of the first material is defined, at least in part, by a first portion of a first tangible conical surface, wherein the first tangible conical surface establishes (i) a first conical apex, and (ii) a first conical-surface volume;
- a second hole in a second portion of the first material composing the article of manufacture, wherein the second hole in the second portion of the first material is defined, at least in part, by a second portion of a second tangible conical surface, wherein the second tangible conical surface establishes (i) a second conical apex, and (ii) a second conical-surface volume;
- and
- a third hole in a third portion of the first material composing the article of manufacture, wherein the third hole in the third portion of the first material is defined, at least in part, by a third portion of a third tangible conical surface, wherein the third tangible conical surface establishes (i) a third conical apex, and (ii) a third conical-surface volume;
- and
- a coating of a second material that fills, at least partially, the first hole such that the coating prevents the mating surface of a conical probe from fitting with the first tangible conical surface;
- wherein the first conical apex, the second conical apex, and the third conical apex are non-collinear;
- and
- wherein the first conical-surface volume does not equal the second conical-surface volume.

- wherein the first conical apex, the second conical apex, and the third conical apex are non-collinear;
- and
- wherein the first conical axis and the second conical axis are non-parallel.
