NON-CONTACT SENSOR SYSTEM AND METHOD FOR POSITION DETERMINATION
First Claim
1. A non-contact sensor system, comprising:
- a first sensor element disposed on an outside surface of a chamber comprising an inside surface configured to receive a piston, wherein the piston is configured to move a value X within the chamber without physically contacting the first sensor element; and
a second sensor element disposed on the piston and separated from the first sensor element by a wall of the chamber, wherein the first sensor element and the second sensor element are operatively coupled to facilitate sensing the value X.

Abstract
A non-contact sensor system is provided that comprises a first sensor element disposed on an outside surface of a chamber. The chamber comprises an inside surface configured to receive a piston, and the piston is configured to move a value X within the chamber without physically contacting the first sensor element. The non-contact sensor system further comprises a second sensor element disposed on the piston and separated from the first sensor element by a wall of the chamber. The first sensor element and the second sensor element are operatively coupled to facilitate sensing the value X. The non-contact sensor system may be configured to sense velocity, acceleration, volume, and other values.
