A three phase fractal generator system includes an armature plate, having a first conductor winding having nine fractal circles wrapped in wire; a second conductor winding having nine fractal circles wrapped in wire; and a third conductor winding having nine fractal circles wrapped in wire; a fractal field relay positioned on top of the armature plate, the fractal field relay having, an inner, middle, and outer circular row of magnets; each magnet is flanked by a magnet with an opposite pole; and a position and proximity of each of the magnets in the fractal field relay create a compressed woven magnetic field that reduces bleed off while channeling a peak strength to the armature plate and spins relative to the armature plate.

A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latching blocking structure coded magnet relative to the filter cartridge coded magnet may be perpendicular or parallel with respect to each other. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a shear force is generated between the magnets when the filter cartridge is inserted within the manifold sump housing, allowing for actuation of the latch blocking mechanism against a biasing force, and allowing the latch to move radially inwards against a separate biasing force.

A magnetic bearing system for controlling magnetic coupling between a mobile carriage and a guideway. The magnetic bearing system includes at least two engines successively arranged in a travel direction, wherein each of the at least two engines comprises at least two poles. The at least two engines have centerlines in the travel direction that are fixedly offset from each other, and the at least two engines are configured to be magnetically coupled to the guideway through air gaps.

An external actuation device includes a housing, a motor, a driving magnet, a sensor, and a controller. The motor includes a driveshaft that is rotatable about a rotation axis. The driving magnet is rotatably coupled with the driveshaft and is rotatable together with the driveshaft about the rotation axis. The sensor is associated with the driving magnet and is configured to detect a magnetic force between the driving magnet and a driven magnet disposed adjacent to the driving magnet. The controller is in communication with the motor and the sensor.

An external magnetic actuator for use in adjusting an implantable medical device having a magnetically actuatable rotatable portion, such as an intramedullary (EVI) lengthening nail is disclosed. The actuator may include a magnet having opposite major surfaces representing opposite poles of the magnet. The magnet may be contained within an actuator body having first and second handles coupled to first and second opposing side walls of the housing. The actuator body may also include one or more projections operable to prevent first and/or second walls of the actuator body from lying flat against an external planar surface. Also provided are various kits and systems that include a disclosed external magnetic actuator and methods for using the disclosed external magnetic actuator.

An augmented reality, virtual reality, and/or mixed reality (AR/VR) system includes an interface device configured to be worn by a user. The interface device includes a frame supporting a reaction material. The AR/VR system also includes a visualization device configured to display virtual features for visualization by the user. The visualization device includes an electromagnet configured to magnetically couple to the reaction material. The AR/VR system further includes a controller electrically coupled to the electromagnet and configured to adjust operation of the electromagnet to modulate a magnetic coupling force between the electromagnet and the reaction material.

Magnetic force adjustment mechanisms are described herein. An electronic device includes a base, a first magnet carried by the base, a lid and a second magnet carried by the lid. The first and second magnets secure the base and the lid together with a holding force. A hinge pivotally couples the lid and the base. A slider displaces at least one of the first or second magnets relative to the other of the first or second magnets to reduce the holding force.

A headset is described that utilizes magnetic frictional couplers. A coupler includes a first member having a first engagement surface and a second member having a second engagement surface disposed for relative positioning of the first and second members along a line of adjustment. One or more magnetic elements are arranged on the first and second members to establish a magnetic flux between the first engagement surface and the second engagement surface, and thereby establishing a frictional force tending to hold the relative positions of the first and second members. The magnetic flux varies as a function of relative position of the first and second members along the line of adjustment, and has peaks at a plurality of detent positions along the line of adjustment.

A flywheel device includes a base, a cantilever mounted on the base, a bearing seat mounted on the base, first magnetic members mounted on the base, a rotation shaft arranged between the cantilever and the bearing seat, a magnetically floating seat mounted on the rotation shaft, second magnetic members mounted on the magnetically floating seat and corresponding to the first magnetic members, third magnetic members mounted on the magnetically floating seat, a repulsion driver locked on the base and surrounding the magnetically floating seat, fourth magnetic members mounted on the repulsion driver and corresponding to the third magnetic members, and a flywheel unit mounted on the rotation shaft. The second magnetic members have a polarity the same as that of the first magnetic members. The fourth magnetic members have a polarity the same as that of the third magnetic members.

A system for connecting and monitoring a magnetic operator interface assembly. The assembly can provide protection of an operator interface by limiting glare, UV damage, and exposure to rain. It can also protect the operator interface from high pressure cleaning equipment. The assembly is removably magnetically mountable to a sealed enclosure without breaching the enclosure's seal. The magnetic operator interface assembly can withstand operational forces, staying at a magnetically fixed position and without becoming accidentally detached. It is also easy to intentionally install and remove. The system may include sensors that can inform a local or remote dashboard about the status of the magnetic operator interface assembly, such as whether it is installed and whether the cover is open or closed. The system may also include a locking system to prevent tampering and limit access to the operator interface.
