Patent ID: 8098122

Claim:
A system for generating a detachable magnetic attachment force with a selective attachment property, said system comprising: a first magnetic structure for association with a first article, said first magnetic structure comprising magnetic field components configured in accordance with a first code; said first code having a first maximum autocorrelation magnitude; a first complementary magnetic structure complementary to said first magnetic structure, said first complementary magnetic structure for association with a first magnetic attachment position, said first magnetic structure and said first complementary magnetic structure having an attachment configuration and a release configuration when in mechanical alignment; a second magnetic structure for association with a second article, said second magnetic structure comprising magnetic field components configured in accordance with a second code, said second code having a second maximum autocorrelation magnitude; a second complementary magnetic structure complementary to said second magnetic structure, said second complementary magnetic structure for association with a second magnetic attachment position, said second magnetic structure and said second complementary magnetic structure having an attachment configuration and a release configuration when in mechanical alignment; said first code and said second code having a cross correlation function having a peak magnitude less than half of said first maximum autocorrelation magnitude and less than half of said second maximum autocorrelation magnitude; said first magnetic structure having an attraction to said second complementary magnetic structure in accordance with said cross correlation function when said first magnetic structure and said second complementary magnetic structure are in mechanical alignment.
