11/983895

Inventors:

Daniel Yves Abramovitch - Palo Alto CA, US
George Hsu - San Jose CA, US

Assignee:

Sensor Platforms, Inc. - San Jose CA

International Classification:

G11B 5/596

US Classification:

360 7703

Abstract:

Embodiments of mitigating the effects of disturbances of a disk drive are disclosed. One method includes sensing a position error signal of a transducer coupled to a surface of the disk drive, wherein the position error signal aids in control of an actuator of the disk drive. A first disturbance signal is generated by sensing a disturbance of a first sensor attached to the disk drive, wherein the first disturbance signal aids in control of the actuator. A second disturbance signal is generated by sensing a disturbance of a second sensor attached to the disk drive, wherein the second disturbance signal aids in control of the actuator. Effects of the disturbances on the position error signal are reduced by adaptively adjusting a gain of the first disturbance signal and a gain of the second disturbance signal.

Abstract:

A method for fabricating an integrated electronic compass and circuit system. The fabrication method begins with providing a semiconductor substrate comprising a surface region. One or more CMOS integrated circuits are then formed on one or more portions of the semiconductor substrate. Once the CMOS circuits are formed, a thickness of dielectric material is formed overlying the one or more CMOS integrated circuits. A substrate is then joined overlying the thickness of the dielectric material. Once joined, the substrate is thinned to a predetermined thickness. Following the thinning process, an electric compass device is formed within one or more regions of the predetermined thickness of the substrate. Other mechanical devices or MEMS devices can also be formed within one or more regions of the thinned substrate.

US Classification:

427213

Abstract:

A process and apparatus for thermally decomposing silicon containing gas for deposition on fluidized nucleating silicon seed particles is disclosed. Silicon seed particles are produced in a secondary fluidized reactor by thermal decomposition of a silicon containing gas. The thermally produced silicon seed particles are then introduced into a primary fluidized bed reactor to form a fludized bed. Silicon containing gas is introduced into the primary reactor where it is thermally decomposed and deposited on the fluidized silicon seed particles. Silicon seed particles having the desired amount of thermally decomposed silicon product thereon are removed from the primary fluidized reactor as ultra pure silicon product. An apparatus for carrying out this process is also disclosed.

Abstract:

High sulfur crude oil is desulfurized by a low temperature (25. degree. -80. degree. C. ) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0. 3) followed by a water and caustic wash to remove sulfur and chlorine containing reaction products. The process can be practiced at the well site for the recovery of desulfurized oil used to generate steam for injection into the well for enhanced oil recovery.
