De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.

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.

An input device comprising a processor(s), an input element, an electropermanent magnet (EPM) assembly including: a permanent magnet operable to generate a magnetic field; and a magnetizing assembly configured to set a magnetic field generated by the permanent magnet, a first ferromagnetic element, and a second ferromagnetic element. The first ferromagnetic element is configured to part and move away from the second ferromagnetic element as the input element is depressed. When the EPM assembly magnetizes the permanent magnet to a first polarity, the first and second ferromagnetic elements are magnetically attracted to each other and provide an attracting that magnetically opposes the first and second ferromagnetic elements from parting, and when the EPM assembly magnetizes the permanent magnet to a second polarity, the first and second ferromagnetic elements are not magnetically attracted to each other and do not magnetically oppose the first and second ferromagnetic elements from parting.

A switchable magnetic filter for collecting metallic particles in a fluid flowing through a vessel, comprising a handle for rotatably or slidingly engaging a magnetic assembly within a housing to an ON position to create a magnetic field outside of the housing to collect and retain metallic particles against the outer wall of the housing, and to an OFF position to shunt the magnetic field within the housing to release the metallic particles from the outer wall of the housing so they may be removed from the fluid for cleaning purposes.

A magnetic buckle device has a first base, an inserting component, a second base, a first component, and a second component. The inserting component can be inserted into the first base, which engages the inserting component. The first base and the second base can move or rotate with respect to each other, thereby converting the inserting component into the unbuckled state. The first and second components are respectively mounted on the second base and the inserting component. When the inserting component is close to an inserting component receiver of the first base, a magnetic attraction force is generated between the second component and the first component for drawing the inserting component to the inserting component receiver. When the inserting component is inserted completely, the magnetic attraction force auxiliary keeps the inserting component in the buckled state, so any additional buckling structure is not necessary.

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.
