Abstract
A position sensor is disclosed with detector elementscoupled to a set of output linesaccording to a connection pattern. An objecttriggers a window subset of the detector elements, causing a logic output on the set of output lines. Some output linesare coupled to more that one detector element. However, the connection patternis arranged such that for any window subset of the detector elements falling in a variable length range, a unique logic output is provided on the set of output linesto identify the position of the object. A sensing method and search process for determining the connection pattern are also disclosed.
