Abstract

A magnetic attachment system for attaching a first object to a second object. A first magnet structure is attached to the first object and a second magnet structure is attached to the second object. The first and second objects are attached by virtue of the magnetic attraction between the first magnet structure and second magnet structure. The magnet structures comprise magnetic elements arranged in accordance with patterns based on various codes. In one embodiment, the code has certain autocorrelation properties. In further embodiments the specific type of code is specified. In a further embodiment, an attachment and a release configuration may be achieved by a simple movement of the magnet structures. In a further embodiment, a magnetic attachment system may comprise one or more magnetic structures spaced from one another on a first support and configured for use with a complementary magnet system.

Dependent claims

A magnetic attachment system, comprising:

a first magnetic structure comprising a first plurality of magnetic field sources arranged linearly and having a first polarity sequence;
and
a second magnetic structure comprising a second plurality of magnetic field sources arranged linearly and having a second polarity sequence;
said first magnetic structure and said second magnetic structure being arranged in a straight line, said first magnetic structure and said second magnetic structure being separated by a spacing, said first polarity sequence being the second polarity sequence in reverse order;
said magnetic attachment system configured for producing a peak attractive force when aligned with a complementary magnetic attachment system where complementary magnetic field sources of said complementary magnetic attachment system are directly across an interface boundary from said first plurality of magnetic field sources and said second plurality of magnetic field sources of said magnetic attachment system, said peak attractive force resulting in a magnetic attachment of said magnetic attachment system to said complementary magnetic attachment system.
