US Classification:

361803, 361796, 361785, 439 59

Abstract:

A substantially rigid card having a first side and an opposing second side, a first connector end adapted to mate with a first expansion connector on a circuit board and a second connector end adapted to mate with a second expansion connector on the board. A first peripheral card connector is connected to the first side and electrically connected to the first connector end, wherein the first connector is of a first form factor and adapted to mate with a first peripheral card. A second peripheral card connector is connected to the second side and electrically connected to the second connector end, wherein the second connector is of a second form factor different from the first form factor and matable with a second peripheral card. The first peripheral card connector is spaced from the first connector end a distance approximately the same as the distance the second peripheral card connector is spaced from the second connector end such that the peripheral card carried by the riser card shares approximately the same region whether the riser card is in a first or a second orientation.

Julie Anne Morris - Raleigh NC, US
Jennifer Greenwood Zawacki - Hillsborough NC, US
Michael Thano Matthews - Cary NC, US

Assignee:

Lenovo (Singapore) Pte. Ltd. - Singapore

International Classification:

H02J 7/00

US Classification:

320137, 320108, 320114, 320127

Abstract:

A technique for charging a wireless device includes detecting a physical presence of a user with respect to the device. A magnetic force is provided between a charging pad and the device only when the physical presence of the user, with respect to the device, is not detected. In this case, a rechargeable power source of the device receives a charging current from the charging pad via conductive contacts of the device.

Assignee:

Lenovo (Singapore) Pte. Ltd. - Singapore

International Classification:

H02J 7/00

US Classification:

320108, 320107

Abstract:

A polygonal power pad includes an optional connector to connect to a power supply and a power network in the power pad. At least one power connector is coupled to the power network and is disposed on a periphery of the pad. The power connector is operable to receive and provide power to a provided adjacent pad. At least one power transfer coil embedded in the pad, is coupled to the power network to transfer power to a device proximate the pad.

Abstract:

An apparatus and method are disclosed for variable authentication requirements. The apparatus includes an operating status module identifying a change in an operating status of a device and maintaining a history of operating statuses, and an access control module comparing a current operating status with a previous operating status. The apparatus also includes a profile module maintaining a trust indicator for each operating status. The access control module determines a level of authentication required to unlock the device in response to the trust indicator associated with the current operating status. The method includes identifying a change in an operating status of a device and maintaining a history of operating statuses, and comparing a current operating status with a previous operating status. The method also includes maintaining a trust indicator for each operating status, and determining a level of authentication required to unlock the device in response to the trust indicator associated with the current operating status.
