Patent ID: 7750778

Claim:
A system for attachment 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; 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, said first object becoming attached to 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 correlation function being in accordance with a first code, said first code defining a code modulo of said plurality of first field emission sources, said second correlation function being in accordance with a second code, said second code defining a code modulo of said plurality of second field emission sources, said first code and said second code defining a peak spatial force, said peak spatial force being produced when said code modulo of said plurality of first field emission sources is substantial aligned with said code modulo of said plurality of second field emission sources, said first code and said second code defining a plurality of off peak spatial forces, said plurality of off peak spatial forces being produced when said code modulo of said plurality of first field emission sources are oriented in a corresponding plurality of different misalignments with said code modulo of said plurality of second 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.
