Patent ID: 7760058

Claim:
A method for producing a spatial force, comprising: providing a first object having a first plurality of field sources; providing a second object having a second plurality of field sources, each of said first plurality of field sources and said second plurality of field sources having a position, a polarity, and a field strength in accordance with a desired spatial force function; and moving at least one of said first object or said second object to align at least some of said first plurality of field sources with at least some of said second plurality of field sources to produce a desired spatial force, said spatial force function being in accordance with a code, said code corresponding to a code modulo of said first plurality of field sources and a complementary code modulo of said second plurality of field sources, said code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first plurality of field sources with said complementary code modulo of said second plurality of field sources, said code also defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first plurality of field sources and said complementary code modulo of said second plurality of field sources, said plurality of off peak spatial forces having a largest off peak spatial force, said largest off peak spatial force being less than half of said peak spatial force.
