Patent ID: 7414503

Claim:
A pivoting device with improved coupling between a permanent magnet attached to the device and an electrical coil, the pivoting device comprising: an elongated hinge layer having a front side and a back side and a first end and a second end, said hinge layer defining a pivoting structure comprising a pair of torsional hinges extending along a pivot axis, a magnet support area at a first location on said back side of said pivoting structure, and a functional area at a second location of said pivoting structure, said pivoting structure supported by said torsional hinges so as to pivot about said pivot axis; a permanent magnet attached to said hinge layer at said magnet support area on said back side; a coil support having a top surface defining a cavity extending to a selected depth level, said coil support further defining a windings area; a multiplicity of electrical windings in said windings area, said electrical windings having top most windings at a level no lower than, the selected depth of said cavity; and a support structure for supporting said pivoting structure such that said permanent magnet attached to said hinge layer is located at least partially within said cavity.
