Abstract:
1. A system for alignment of objects, comprising: a first field emission structure affixed to a first object, said first field emission structure having a plurality of first field emission sources having polarities in accordance with a first correlation function defined by a first code; and a second field emission structure affixed to a second object, said second field emission structure having a plurality of second field emission sources having polarities in accordance with a second correlation function defined by a second code, said first object becoming substantially aligned with said second object when each one of said plurality of first field emission sources becomes substantially aligned with a corresponding one of said plurality of second field emission sources thereby producing a peak attractive spatial force in accordance with said first correlation function and said second correlation function, said first code and said second code corresponding to a spatial force function, said first code corresponding to a code modulo of said first field emission structure and said second code corresponding to a code modulo of said second 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 field emission structure with said code modulo of said second 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 field emission structure and said code modulo of said second 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.
