Abstract

A method and system for monitoring moving parts relies upon a formatted surface of a moving part. The formatted surface includes an address pattern wherein a precise position relative to the address pattern can be determined from a portion of the address pattern. An electronic reading sensor detects a portion of the address pattern, and a processor uses the detected portion of the address pattern to determine a current position of the moving part.
