An electronic device includes a first housing including a first side surface, a second housing including a second side surface that may face at least a portion of the first side surface, a first magnet group disposed adjacent to the first side surface in the first housing and including a first designated pattern along a lengthwise direction, and a second magnet group disposed adjacent to the second side surface in the second housing and including a second designated pattern along a lengthwise direction, wherein the first designated pattern of the first magnet group and the second designated pattern of the second magnet group are alternately magnetized with an N pole or an S pole, and wherein the first housing and the second housing are coupled together to be rotatable by the first magnet group and the second magnet group.

A mount bush includes a tubular member, a shaft member disposed inside the tubular member coaxially with an axis of the tubular member and including a coil, a permanent magnet provided on at least one of the tubular member and the shaft member, a magnetic viscoelastic fluid filled in an internal space, a first liquid chamber disposed in the internal space at a first side, a second liquid chamber communicating with the first liquid chamber, and a third liquid chamber communicating with the second liquid chamber, wherein the coil is disposed such that a magnetic path passing through the second liquid chamber in an orientation along at least one of the axial direction and the radial direction perpendicular to the axial direction is formed through electrical conduction, and the permanent magnet is disposed such that a magnetizing direction is formed along the magnetic path.

A gravity-fed filtration system interconnection structure comprising a reservoir for receiving ingress fluid, and a second, dispensing reservoir. A carrier or shuttle having a carrier magnet is connected to a sluice gate valve which normally blocks the opening to the second reservoir. A filter cartridge may be received by the reservoir and includes a housing body, and a filter magnet disposed within or fixedly connected to the housing body. The filter magnet and the carrier magnet are interconnected via magnetic communication upon insertion of the filter cartridge into the reservoir recess, to move the carrier and/or sluice gate valve as a result of shear force or rotational force generated between the magnets.

A field magnet manufacturing method where a bonded magnet's inner surface press-fitted in a yoke has a certain accuracy irrespective of the accuracy of the yoke's outer circumferential surface. A cylindrical bonded magnet from binding magnet particles with a thermosetting resin is fixed in a tubular yoke of magnetic material. The method includes reheating and softening the bonded magnet after thermal curing; and press-fitting in the bonded magnet after the softening step from a tapered portion on one end side of the yoke to press the bonded magnet's outer circumferential surface against the yoke's inner surface. The press-fitting includes feeding the bonded magnet relatively into the yoke while allowing a relative posture variation between the bonded magnet and the yoke so the bonded magnet's inner surface to be remolded into a shape along the inner surface of the yoke exhibits almost the same accuracy as the yoke's inner surface.

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.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The joints connecting the modules are designed such that power and data connections between modules are reliably made.

An arrangement of cancellation electromagnets control magnetic adhesion of a wheel to a surface. The wheel has an inner annular disc composed of a non-magnetic material with apertures which retain electromagnets and permanent magnets, and an outer annular disc composed of a ferromagnetic material which is disposed on a side of the inner annular disc, with a non-magnetic isolator ring having curves extending in a serpentine manner. In one embodiment, the curves isolate the electromagnets from the permanent magnets. In another embodiment, the outer annular disc is rotated relative to the inner annular disc to dispose the curves of the serpentine isolator ring in a second position to allow magnetic interaction between the electromagnets and the permanent magnets to generate a second magnetic flux between the permanent magnets and the ferromagnetic surface which decreases adhesion of the wheel to the ferromagnetic surface. A method implements the system.
