Abstract: A switchable permanent magnetic unit is disclosed. The unit comprises: a housing, first and second permanent magnets, and a conductive coil. The first magnet is mounted within the housing and the second magnet is rotatable between first and second positions and mounted within the housing in a stacked relationship with the first magnet. The unit generates a first level of magnetic flux at a workpiece contact interface when the second magnet is in the first position and a second level of magnetic flux at the interface when the second magnet is in the second position, the second level being greater than the first level. The conductive coil is arranged about the second magnet and generates a magnetic field. A component of the conductive coil's magnetic field is directed from S to N along the second magnet's N-S pole pair when the second magnet is in the first position.

Abstract: An electromagnetic mooring system (MMS) that includes a first object and a second object, at least one of which includes an electronic coupler configured to connect the first object with the second object. The electronic coupler comprises a pair of magnets, at least one of which is an electro permanent magnet (EPM), having a flux path. When the electronic coupler is in the ON states, the flux path moves towards the first or second object transferring heat from the first or second object to the second or first object, and when the electronic coupler is in the OFF state, the flux paths moves towards the EPM.

Abstract: An apparatus and method for attaching a crawler vehicle to the surface of an object. The crawler vehicle may comprise a frame, a number of moveable surface-engaging components attached to the frame, a number of actuators, and an electro-permanent magnet. The number of actuators is operable to move the frame with respect to the object when the number of moveable surface-engaging components is in contact with the surface of the object. The electro-permanent magnet is operable to hold the number of moveable surface-engaging components in contact with the surface of the object by a magnetic force between the electro-permanent magnet and the object when the electro-permanent magnet is activated and to remove the magnetic force when the electro-permanent magnet is deactivated to release the number of moveable surface-engaging components from the surface of the object.

Abstract: An inductive charging interface with magnetic retention can be used for charging electronic devices and accessories. For example, a magnetic core of an inductive charging configuration may be divided into two magnetic elements, one element can be housed within a receptacle or receiving connector of housing of an electric device and the other element can be housed within a plug or transmission connector. The poles of the two elements of the magnetic core may create a magnetic field to retain the plug connector in an aligned, mated position with the receptacle connector of the electronic device in addition to directing magnetic flux to flow in a circular path around and between the two elements of the magnetic core, thereby inducing a current for charging the internal battery of a device.
