Patent ID: 7961069

Claim:
A magnetic attachment system for attaching a first object to a second object, said system comprising: a first magnet structure for attachment to said first object, said first magnet structure comprising a plurality of magnetic field components, said plurality of magnetic field components arranged according to a first pattern; and a complementary magnet structure for attachment to said second object, said complementary magnet structure comprising a plurality of magnetic field components arranged according to a complementary pattern complementary to said first pattern; said first pattern based on a variable code having an autocorrelation function with a single maximum peak per code modulo and a plurality of off maximum peak positions; said first magnet structure and said complementary magnet structure having an operational range of relative position; wherein magnetic force between said first magnet structure and said complementary magnet structure as a function of position within said operational range corresponds to said autocorrelation function; said autocorrelation function having a plurality of positions corresponding to said operational range wherein the greatest off maximum peak autocorrelation magnitude is less than half of the single maximum peak; said first magnet structure and said complementary magnet structure capable of providing attachment of said first object to said second object through magnetic attraction of said first magnet structure to said complementary magnet structure.
