Patent ID: 7843294

Claim:
A system for moving an object, comprising: a first magnetic field emission structure associated with a first object, said first magnetic field emission structure being in accordance with a first code; an array of electromagnets associated with a second object; and a control system, said control system controlling the state of said array of electromagnets to produce a second magnetic field emission structure, said second magnetic field emission structure being in accordance with a second code, said control system varying at least one characteristic of said second magnetic field emission structure thereby causing movement of at least one of said first object or said second object, said first code and said second code corresponding to a spatial force function, said first code corresponding to a code modulo of said first magnetic field emission structure and said second code corresponding to a code modulo of said second magnetic field emission structure, said first code and said second code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first magnetic field emission structure with said code modulo of said second magnetic field emission structure, said first code and said second code also defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first magnetic field emission structure and said code modulo of said second magnetic field emission structure, 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.
