Abstract
A method for determining a position of a magnet assembly relative to an array of inductive elements arranged adjacent to a magnetically permeable material, the method involving: measuring electrical characteristics of each of one or more inductive elements of the array of inductive elements; and from information derived from the measured electrical characteristics of the one or more inductive elements of the array of inductive elements, determining the position of the magnet assembly relative to the array of inductive elements.
