  • Publication number: 20130065406
    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.

  • Patent number: 8199468
    Abstract: A multipart computer housing is described. The multipart computer housing includes at least a clutch barrel. The clutch barrel encloses a connector assembly, the connector assembly providing support for a lid. The clutch barrel is configured such that a junction formed by the clutch barrel and a top layer of the lid is not visible to a user when the computer housing is on a horizontal surface.

  • Publication number: 20120092821
    Abstract: A multipart computer housing is described. The multipart computer housing includes at least a structural support layer and a body. The body includes at least an outer layer formed of lightweight flexible material and an inner layer attached to the outer layer. The inner layer is connected to the support layer forming a load path between the inner layer and the structural support layer. A load applied to the multipart computer housing is transferred by way of the load path to the support layer without substantially affecting the outer layer.

  • Publication number: 20120049702
    Abstract: Electronic device frames may be formed from fiber composites. Carbon fiber material may be formed into frame members using pultrusion tools. Notches may be machined into the frame members. The machined frame members may be assembled to form a rectangular frame assembly using lap joints. Fiber tape may be wound around the periphery of the frame assembly. Following curing, additional parts such as a metal blank may be bonded to the frame assembly and machined.

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 or both of the plug and receptacle can be a magnet, which is preferably a permanent rare earth magnet although electromagnets may also be used. The magnetic element on the plug or receptacle that does not include a magnet is composed of ferromagnetic material. When the plug and receptacle are brought into proximity, the magnetic attraction between the magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

  • Publication number: 20110038582
    Abstract: Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.

  • Patent number: 7762817
    Abstract: An electronic device is disclosed. The electronic device includes a first subassembly having a first housing component. The first housing component has an opening. The electronic device also includes a second subassembly having a second housing component. The second housing component cooperates with the first housing component to enclose components of an electronic device. The at least one internal component is also movable relative to the second subassembly so as to properly align with the opening. The at least one internal component is additionally magnetically attracted towards the first housing component near the opening.
