Patent ID: 7843295

Claim:
A detachable panel system comprising: a panel to be attached to a support; a first magnet structure attached to said panel, 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 attached to said support, said complementary magnet structure comprising a plurality of magnetic field components arranged according to a complementary pattern complementary to said first magnet structure; said first pattern based on a variable code having an autocorrelation function with a single maximum peak per code modulo; 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 providing attachment of said panel to said support through magnetic attraction of said first magnet structure to said complementary magnet structure, said first magnet structure having an alignment configuration relative to said complementary magnet structure, said alignment configuration having a maximum magnetic attraction to said complementary magnet structure corresponding to said single maximum peak autocorrelation, said first magnet structure having a release configuration relative to said complementary magnet structure, said release configuration realized by movement of said first magnet structure from said alignment configuration to said release configuration in accordance with a degree of freedom between said first magnet structure and said complementary magnet structure, said movement less than a full width of said first magnet structure.
