Classification: CPC F  G | IPC F  G

Claim 15:
16. A valve system comprising:
at least one shaft comprising at least one conductive material, the at least one conductive material extending along an axis of movement of the at least one shaft and radially surrounding the at least one shaft to an outer surface of a portion of the at least one shaft; and
a first inductance-to-digital converter (LDC) sensor and a second inductance-to-digital converter (LDC) sensor separated from the at least one conductive material of the at least one shaft, the first inductance-to-digital converter (LDC) sensor comprising an inductor and configured to wirelessly sense a position of a portion of the at least one conductive material, wherein the second inductance-to-digital converter (LDC) sensor to sense another position of another portion of the at least one conductive material, and wherein the valve system is configured to compare the another position to a known position of the at least one conductive material based on the sensed position from the first inductance-to-digital converter (LDC) sensor, wherein the valve system is configured to determine a deviation of the another position of the another portion of the at least one conductive material from the known position, and wherein the valve system is configured to indicate a deformation in the at least one shaft based on the determined deviation of the another position of the another portion of the at least one conductive material.
