US Patent:

8255302, Aug 28, 2012

Filed:

Apr 10, 2008

Appl. No.:

12/082280

Inventors:

Mike Chen - New York NY, US

Assignee:

Morgan Stanley - New York NY

International Classification:

G06F 35/00

US Classification:

705 35

Abstract:

Computer-implemented methods for valuing a derivative based on the BMA rate: the methods may comprise generating a model of the BMA/LIBOR ratio as a function of the LIBOR index, a stochastic noise function, and a seasonality process. The methods may also comprise solving the model for at least one value of the LIBOR index, and estimating a value of the derivative given the solution of the model. The value of the derivative may then be stored.

Mike Chen - Daly City CA, US

Neil Robertson - Palo Alto CA, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION

International Classification:

C25C003/36

US Classification:

205/365000

Abstract:

A process for electroplating and annealing thin-films of nickel-iron alloys having from 63% to 81% iron content by weight to produce pole pieces having saturation flux density (B) in the range from 1.9 to 2.3 T (19 to 23 kG) with acceptable magnetic anisotropy and magnetostriction and a coercivity (H) no higher than 160 A/m (2 Oe). The desired alloy layer properties, including small crystal size and minimal impurity inclusions, can be produced by including higher relative levels of Fe ions in the electroplating bath while holding the bath at a lower temperature while plating from a suitable seed layer. The resulting alloy layer adopts a small crystal size (BCC) without significant inclusion of impurities, which advantageously permits annealing to an acceptable Hwhile retaining the high Bdesired.

International Classification:

G11B021/02

US Classification:

360/071000, 360/075000

Abstract:

A thin-film write head employing pole pieces formed of an electroplated body-centered cubic (BCC) nickel-iron alloy with a saturation flux density (B) of 1.9 to 2.3 T (19 to 23 kG) and an acceptable coercivity (H) of about 80 to about 160 A/m (1-2 Oe). The iron content of the electroplated nickel-iron alloy is from 64% to 81% by weight. The two-layer pole fabrication process holds magnetic anisotropy and coercivity to useable values while improving saturation flux density and optimizing magnetostriction. This is accomplished by first electroplating a BCC nickel-iron layer onto an underlying seed layer and then annealing the two layers to reduce coercivity to less than about 160 amps/meter and raise magnetization to acceptable levels.

11/533623

Inventors:

Rob Rao - Hercules CA, US
Mike Chen - Richmond VA, US

International Classification:

A61B 17/08

US Classification:

606151000

Abstract:

A surgical method and apparatus of repairing a tear, cut or defect in the body tissue, specifically the dura or vascular wall, is disclosed. An inner plate is placed on the tissue's inner surface in a position completely overlapping the tissue defect. An outer plate is placed on the tissue's outer surface in a position completely overlapping the defect and aligned with the inner plate, whereby the inner and outer plates have perimeters larger than the perimeter of the defect. The inner plate is coupled to the outer plate such that the peripheral edges of the body tissue defect are securely clamped between the inner and outer plates to provide a watertight repair to the tissue defect. An associated clamping apparatus and insertion tool is disclosed. An anastomotic clamping device for a body lumen is also disclosed using opposed annular clamping plates.

Abstract:

Social media networking applications, web sites, and services creates implicit relationships between users based on their interest or participation in real-world and optionally virtual or online activities in addition to explicitly defined peer relationships. User profiles, activity entities, and expressions may be associated with metadata to assist in searching and navigation. Metadata is implicitly associated with user profiles, activity entities, expressions, or other data entities based on user behavior using metadata collector. A metadata collector is a poll, survey, list, questionnaire, census, test, game, or other type of presentation adapted to solicit user interaction. A metadata collector is associated with metadata elements. When users interact with a metadata collector, their user profiles and the data entities included in their interactions become associated with the metadata elements of the metadata collector. These metadata element associations may then be used for any purpose.
