Abstract
A method that includes: providing a structure that is movable along a first axis; coupling a sensor assembly to the structure, the sensor assembly comprising first and second eddy current sensors and first and second targets that are mounted to the structure for movement along the first axis; sensing the first target with the first eddy current sensor and responsively generating a first sensor signal; sensing the second target with the second eddy current sensor and responsively generating a second sensor signal; and using the first and second sensor signals to determine a location of the structure along the first axis in a manner that is insensitive to coordinated movement of the first and second targets along a second axis that is perpendicular to the first axis and a third axis that is perpendicular to both the first and second axes.
