Abstract / Hauptanspruch
A position sensing system including a waveguide, a magnet movable relative to the waveguide, and a compensator configured to compensate for a change in propagation velocity of the waveguide in determining a position of the magnet relative to the waveguide. The compensator coupled to the waveguide and configured to receive a pulse, an end of line pulse corresponding to the pulse transmitted through the waveguide, and a reflected pulse corresponding to a reflection of the pulse at a point in the waveguide. The compensator configured to determine the point based at least in part on the pulse, the end of line pulse, and/or the reflected pulse.
