Abstract: An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.

Abstract: An electrical plug and receptacle relying on magnetic force from an electromagnet to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one of the plug or receptacle can be a magnet or ferromagnetic material. The magnetic element on the other of the plug or receptacle is an electromagnet. When the plug and receptacle are brought into proximity, the magnetic attraction between the electromagnet magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

CPC classification number: G01D5/145
Abstract: This application relates to devices that utilize magnets and associated magnetic sensors. A magnetic sensor can be positioned and oriented with respect to a magnetic element such that the magnetic sensor is capable of detecting a horizontal magnetic field component in contrast to the conventional paradigm of detecting a vertical magnetic field component. This can be accomplished by orienting a magnetically sensitive surface of the magnetic sensor about ninety degrees with respect to a magnetic vector of the magnetic element.

Abstract: An article having a multiple magnetic polarities and a method for making the article are disclosed. The article can be a monolithic substrate form from a metallic material or materials. The article may include a first magnetic polarity and a second magnetic polarity opposite the first magnetic polarity. Methods for making the article include provide either providing a monolithic substrate having a first magnetic polarity, or applying a first magnetic field to the monolithic substrate to impart a first magnetic polarity. The method may also include raising the temperature of the monolithic substrate in order to reduce the coercivity of the monolithic substrate. The temperature of the monolithic substrate may also be selectively raised to lower the coercivity of the monolithic substrate in associated areas. By lowering the coercivity, the second magnetic polarity may be imparted on the monolithic substrate.

Abstract: Power cables that include plug housings having an improved appearance as well as employ a halogen-free cable while providing adequate fire resistance. One example provides a power cable having cable plug with a substantially unitary body. Another example provides a power cable that is formed using halogen-free materials. To provide adequate fire protection, a strain relief formed using multiple materials is used.

Abstract: Magnetic systems can include a controllable magnet array and a fixed magnetic array. The fixed magnetic array can include an array of permanent magnets having alternating polarization direction transverse to the array. Some controllable magnet arrays can include electropermanent magnets (EPMs) arranged end-to-end, with pole pieces between them aligned to the permanent magnets of the fixed magnet array. Each EPM can include a permanent magnet having a fixed magnetic orientation lateral to the array and antiparallel to the permanent magnet in an adjacent EPM and a switchable magnet whose magnetic orientation can be switched between parallel and antiparallel to the permanent magnet in the EPM.
