SENSOR FOR POSITION AND GAP MEASUREMENT
First Claim
1. An apparatus comprising:
- a controller;
a transport in communication with the controller having a movable portion and a transport path; and
a multi-dimensional position measurement device in communication with the controller, the multi-dimensional position measurement device including a plurality of transformers and at least one element attached to the movable portion;
wherein the multi-dimensional position measurement device is configured so that a circuit is completed in at least one of the plurality of transformers as the at least one element passes proximate to the at least one of the plurality of transformers and the controller is configured to simultaneously calculate a multi-dimensional position of the movable object based on an output of the at least one of the plurality of transformers, wherein the multi-dimensional position includes a gap between the movable portion and the plurality of transformers.
