Abstract:
1. A method for producing spatial forces, said method comprising the steps of: defining a first field emission structure, said first field emission structure including a first plurality of field emission sources having positions, polarities, and field strengths in accordance with a desired spatial force function; defining at least one second field emission structure, said at least one second field emission structure including a second plurality of field emission sources having positions, polarities, and field strengths in accordance with said desired spatial force function; associating said first field emission structure with a first object; associating at least one of said second field emission structures with a second object; and moving at least one of said first object or said second object such that said first magnetic field structure successively engages with each of said at least one of said second field emission structures to produce repeating spatial forces, said spatial force function being in accordance with a first code and a second code, said first code corresponding to a code modulo of said first plurality of field sources and said second code corresponding to a code modulo of said second plurality of field emission sources, said first code and said second code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first plurality of field emission sources with said code modulo of said second plurality of field emission sources, 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 plurality of field emission sources and said code modulo of said second plurality of field emission 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.
