Abstract:
1. A magnetic field emission system, comprising: a first magnetic field structure having a number of first magnetic field emission sources, said number of first magnetic field emission sources having corresponding polarities and positions in accordance with a desired spatial force function, said desired spatial force function having a desired peak attractive spatial force; and a second magnetic field structure having a number of second magnetic field emission sources, said number of second magnetic field emission sources having corresponding polarities and positions in accordance with said desired spatial force function, said number of first magnetic field emission sources and said number of second magnetic field emission sources producing said desired peak attractive spatial force at a desired engagement distance at which said first magnetic field emission structure will engage with said second magnetic field emission structure when substantially aligned, said number of first magnetic field emission sources and said number of second magnetic field emission sources having at least one magnetic field emission source strength and at least one magnetic field emission source size selected based upon said desired engagement distance and said desired peak attractive spatial force, said spatial force function being in accordance with a code, said code corresponding to a code modulo of said first magnetic field emission sources and a complementary code modulo of said second magnetic field emission sources, said code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first magnetic field emission sources with said complementary code modulo of said second magnetic field emission 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 magnetic field emission sources, and said complementary code modulo of said second magnetic 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.
