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.

Abstract: Examples provide magnets for electronic devices. The magnets can be formed as unitary structures using metal-injection molding. The magnets can be referred to as neodymium magnets. That is, they can be formed of neodymium, iron, and boron. The magnet can comprise a plurality of easy axes, where the plurality of easy axes are not parallel.

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 electronic device can include a first and second portions that are pivotally coupled to each other so that the electronic device can have at least a closed configuration and an open configuration. A magnetic sensor system can be carried by the electronic device to detect the closed configuration so that the electronic device can automatically turn to a mode, such as a sleep mode, when the electronic device is bought to the closed configuration. A magnetic sensor can have a detection axis that targets a horizontal component of a magnetic field. A triggering magnetic element can be laterally offset relative to the magnetic sensor. The magnetic sensor can also be a magneto-resistive sensor. The electronic device can also include a second set of magnetic sensor system to confirm when the electronic device is brought to the closed configuration.

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: A sleep mode system for an electronic device can include a light source, a sensor, and a light altering component. The light altering component can rotate with one device component, such as a laptop lid, while the light source and/or sensor remain stationary with another device component, such as a laptop base. A controller can determine the orientation angle of the light altering component based on the detected light, and can put the device into or remove the device from a sleep mode based on the angle, which can reflect an open state or closed state for the electronic device.

Abstract: Magnetic connectors that may be readily manufactured and provide a high landed force and labels for magnetic connectors that may protect magnets or magnetic elements in the connectors, provide an aesthetically pleasing appearance, and improve the magnetic performance of the connectors. In various examples, power and signal paths may be formed using contacts that are separate from magnets or magnetic elements, paths may be formed using magnets or magnetic elements, or paths may be formed using a combination of contacts and magnets and magnetic elements. The magnets may have various arrangements. One or more magnets may be used in conjunction with magnetic elements. The interface surface of these magnets and magnetic elements may have various contours, such as flat, spline, or involute.
