Abstract: An apparatus for control of display content (the display content on screen 26) of a portable computer (20) with the use of user initiated motion. Calculations of motions of the device can be made based on the "Javel arc" (104,110), the preferential motion arc along which the device (20) travel. Additionally, the double integration of each accelerometer required in a conventional device is replaced by two magnetic sensors (1004,1006).

Abstract: A method and system for providing a magnetic element are disclosed. The method and system include providing a pinned layer, a free layer, and a spacer layer between the pinned layer and the free layer. The spacer layer is insulating and has an ordered crystal structure. The spacer layer is also configured to allow tunneling through the spacer layer. In one aspect, the free layer is comprised of a single magnetic layer having a particular crystal structure and texture with respect to the spacer layer. In another aspect, the free layer is comprised of two sublayers, the first sublayer having a particular crystal structure and texture with respect to the spacer layer and the second sublayer having a lower moment. In still another aspect, the method and system also include providing a second pinned layer and a second spacer layer that is nonmagnetic and resides between the free layer and the second pinned layer. The magnetic element is configured to allow the free layer to be switched due to spin transfer when a write current is passed through the magnetic element.

Abstract: A method and system for providing a magnetic element that can be used in a magnetic memory is disclosed. The magnetic element includes first pinned, spacer, free, spin barrier, and second pinned layers. The spacer layer is nonmagnetic and resides between the pinned and free layers. The free layer can be switched using spin transfer when a write current is passed through the magnetic element. The free layer resides between the spacer and spin barrier layers. The spin barrier layer is between the free and second pinned layers. The spin barrier layer is configured to reduce an outer surface contribution to the free layer damping constant. In one aspect, the spin barrier layer has a high areal resistance and may substantially eliminate spin pumping induced damping. In another aspect, the magnetic element also includes a spin accumulation layer between the spin barrier and free layers. The spin accumulation layer has a high conductivity and may have a long spin diffusion length.

Abstract: A system and method for calibrating an accelerometer assembly is disclosed. In a preferred embodiment, the system includes a controllable motor that rotates an accelerometer assembly around a first axis of rotation (A1), a rotary stage for rotating and holding the accelerometer assembly to at least one other axis of rotation (A2), and a way to vary and hold constant the temperature. The system also includes a computer system for managing the operation of the temperature control and the operation of the motion generation. The computer system further stores and processes the output signals created by the accelerometer assembly so that certain parameters related to the accelerometer assembly can be determined. The parameters include the angular velocity of rotation around the first axis, the angular position of the accelerometer assembly in relation to its rotation around the second axis, and the third parameter being the temperature of the accelerometer assembly. Using these parameters, the accelerometer can be calibrated.

Abstract: A method for using microlithography to form columns with side surfaces to be provided with an insulating coating and top surfaces having no insulating coating, in magnetic metal multilayers deposited by cathode sputtering or molecular beam epitaxy, so that a current can be circulated perpendicularly to the plane of the layers and the phenomenon of perpendicular giant magnetoresistance can be used. The method comprises a first step of forming on the surface of a substrate (10) a stack consisting of a first conductive layer (8) contacting the substrate, and alternating magnetic layers and non-magnetic metal layers forming a magnetic metal multilayer (7) contacting the conductive layer (8); a second step of forming a second conductive layer on the magnetic metal multilayer (7); a third step of forming a first resin mask (12, 18) having the same size as a magnetoresistive sensitive element to be produced; a fourth step of etching around the mask of the second conductive layer and the magnetic metal multilayer (7); a fifth step of depositing an insulating layer on the structure; a sixth step of lifting off the resin mask and the insulating layer thereon; and a seventh step of restoring contact (21) on the second conductive layer.
