    摘要： A method and system for controlling the provisioning of a device with information for accessing services of a wireless service provider via a wireless network is provided. The provisioning system initially stores automatic provisioning information on the device that includes the identification of wireless service providers that have the capability to automatically provision the device. When a user of the device wants to subscribe to a service of a service provider, the provisioning system requests an automatic provisioning service of the service provider to provide information describing available services and information needed to subscribe to those services. When the user selects a service and provides the needed information, the provisioning system retrieves provisioning information for the selected service from the service provider. The provisioning system stores the provisioning information on the device so that the device can then be used to access the selected service of the service provider.

    摘要： A high speed and low power method to control and switch the magnetization direction and/or helicity of a magnetic region in a magnetic device for memory cells using spin polarized electrical current. The mapetic device comprises a reference magnetic layer with a fixed magnetic helicity and/or magnetization direction and a free magnetic layer with a changeable magnetic helicity and/or magnetization direction. The fixed magnetic layer and the free magnetic layer are preferably separated by a non-magnetic layer. The fixed and free magnetic layers may have magnetization directions at a substantially nonzero angle relative to the layer normal. A current can be applied to the device to induce a torque that alters the magnetic state of the device so that it can act as a magnetic memory for writing information. The resistance, which depends on the magnetic state of the device, is measured to read out the information stored in the device.

    摘要： A prosthetic system comprising a patellar unit to replace the femoral surface of the patella with a convex prosthesis constructed from a low-friction material and an elongate femoral prosthesis for replacing the trochlear groove without use of bone cement. The femoral prosthesis has a arcuate indentation on its upper surface to accommodate the patellar prosthesis and a lower surface with diverging, protruding vanes. The lower surface and the vanes are made of a biocompatible material that promotes bonding to living bone. The femoral prosthesis is inserted by first driving a guide rod into the distal end of the femur. Then a guide frame is inserted onto the rod to guide an instrument in the cutting of a groove in the trochlear portion of the femur. Then a second guide frame replaces the first guide frame and acts as a template for cutting slots sized to receive the vanes of the prosthesis. Finally, the guide frame and rod are removed, and the prosthesis is slid into the cut groove with the vanes occupying the slots. The prosthesis is fixed in place by an insertable peg with no use of bone cement. Over time the interaction of the bone with the vanes results in tight integration of the prosthesis so that it cannot not be loosened.
