Abstract: An electronic device (such as a laptop) may selectively latch a base to a lid using a switchable magnet array. In particular, a drive circuit in the electronic device may apply at least a current pulse to a conductor that generates a magnetic field to reverse a direction of a remnant magnetization in the switchable magnet array. By reversing the direction of the remnant magnetization, the electronic device may selectively increase or decrease a magnetic field generated by the switchable magnet array at an attraction plate in the electronic device. This magnetic field may, in turn, result in an attractive force between the switchable magnet array and the attraction plate, thereby selectively latching the base and the lid when the base and the lid are proximate to each other.

Abstract: A sleep mode system for an electronic device can include a magnetic component and a proximately located sensor configured to detect magnetic field properties that vary with a variable rotation of the magnetic component. The magnetic component can rotate with one device component, such as a laptop lid, while the sensor remains stationary with another device component, such as a laptop base. A controller can determine the orientation angle of the magnetic component based on the detected properties, 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: 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: A method of magnetizing a multi-pole magnet includes the steps of obtaining a magnetization coil having a magnetization zone and a central axis, and positioning a magnet within the magnetization zone. The method also includes positioning at least one pair of shield bodies including a conductive material proximate the first and second surfaces of the magnet, with the shield bodies being aligned together to cover both sides of at least a first region of magnet and expose both sides of at least a second region of the magnet. The method further includes energizing the magnetization coil to generate an applied magnetic field within the magnetization zone that is sufficient to induce eddy currents in the at least one pair of shield bodies and to magnetize the exposed second region of the magnet.
