| 20080280461 | ELECTROMAGNETIC CONNECTOR FOR ELECTRONIC DEVICE - 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. | 11-13-2008 |
| 20100035441 | MAGNETIC CONNECTOR FOR ELECTRONIC DEVICE - An electrical plug and receptacle relying on magnetic force 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 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. | 02-11-2010 |
| 20100080563 | MAGNETIC CONNECTOR WITH OPTICAL SIGNAL PATH - 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. | 04-01-2010 |

| 20110090627 | COMPUTER HOUSING - 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. | 04-21-2011 |
| 20110090632 | COMPUTER HOUSING - 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. | 04-21-2011 |
| 20110092081 | MAGNETIC CONNECTOR HAVING A UNITARY HOUSING - 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. | 04-21-2011 |
