<p>A microelectric position sensor comprising an assembly of magnetic field sensitive elements, each of which assuming a first state when subjected to a magnetic field having an intensity below a first predetermined value, and assuming a second state when subjected to a magnetic field having an intensity above a second predetermined value. Means creating a magnetic field being selectively movable relative to the assembly, whereby the magnetic field sensitive elements are selectively subjected to the magnetic field to selectively assume their first state or their second state. The means creating the magnetic field includes focusing means focusing the magnetic field at a region including substantially only one of said magnetic field sensitive elements, whereby the magnetic field within the region has an intensity above the second predetermined value, and the magnetic field outside the region having an intensity below the first predetermined value. <IMAGE></p> |
