News World’s First Multi-level Correlated Magnetic Devices Demonstrated at Two Major Technology Conferences
Magnets programmed to both attract and repel simultaneously were demonstrated at the SMMA Fall Technical Conference in
Huntsville, Ala., December, 2009 – Correlated Magnetics Research, LLC (CMR) displayed the world’s first multi-level correlated magnetic devices last week at the Interservice/Industry Training, Simulation & Education Conference (I/ITSEC) in Orlando. This new technology was also demonstrated at the SMMA 2009 Electric Motor Technology Leadership Conference in Chicago in November.
CMR has developed two distinct prototype multi-level correlated magnetic devices, each featuring a pair of Coded MagnetsTM that are programmed to both attract and repel simultaneously.
For one prototype, HoverfieldTM magnets are bound to each other through the proximity of their strong magnetic fields, yet the magnet surfaces themselves do not touch. The magnets are held apart by a repel force encoded into the magnet surface, shorter in its reach yet stronger than the “long throw” attract force. The resulting bond is an engineered permanent balance between two opposing magnetic forces, and does not rely on mechanical hardware for attachment.
For the second prototype, two RepelSnapTM magnets are attached at their surface by a strong “short throw” attract force. When the magnet pair are moved out of their correlated attach position, the attraction forces are cancelled and the magnets instantly yield to a longer-range repel force, pushing the magnets apart.
These multi-level magnetic devices employ the theory of correlated magnetics, where magnetic fields and forces are prescribed by encoding a spatial pattern of both “north” and “south” polarities onto two or more surfaces. The surfaces respond to each other according to the way the aggregate magnetic fields are programmed to correlate to each other.
CMR’s HoverfieldTM magnets allow objects to engage and attach without contact, enabling a wide variety of applications from doors that close quietly to high-efficiency reduced-wear automation. Alternatively, RepelSnapTM correlated magnets that repel in the far field but attract in the near field enable replacement of mechanical springs and provide for programmable, repeatable, permanent hysteresis.
In addition to multi-level magnetic behavior, correlated magnetic structures have been developed to enable precision alignment to prescribed tolerances and to bestow unique identities to magnets enabling discrimination among devices.
CMR will license the programmable magnets technology to manufacturers in automotive, aerospace, defense, environmental, construction, biomedical and consumer products industries. CMR has 67 patents filed with the U.S. Patent Office as well as international patent organizations.
