International Classification:

US Classification:

711141, 711147, 711154, 707201, 707203, 707200

Abstract:

A system and method for efficiently performing memory intensive computations including a bidirectional synchronization mechanism for maintaining consistency of data on which computations will be performed. This can be used to solve various problems such as those in a business context. Synchronization occurs in a near-real-time fashion between data in a database and data stored in memory. The synchronization is accomplished by periodically scanning the database to see if any data has changed. If any data has changed, the changes are copied over to memory so that the data in memory is current. This update is accomplished without copying the entire database into memory each time data in the database changes.

Appl. No.:

12/203039

Inventors:

Jin Yang - San Jose CA, US

Assignee:

Sipix Imaging, Inc. - Fremont CA

International Classification:

G02B 26/00
G09G 3/34
G03G 17/04

US Classification:

359296, 345107, 430 32

Abstract:

This invention relates to stable colorants of high extinction coefficient and high solubility or dispersibility for an electrophoretic, magnetophoretic or electromagnetophoretic display. More particularly, it relates to stable colorants for a microcup-based electrophoretic or electromagnetophoretic display the cells of which are filled with charged and/or magnetic particles dispersed in a halogenated, preferably a fluorinated, solvent. The use of the stable colorants allows the display to be of superior contrast ratio and longevity, and suitable for high-quality imagery applications.

International Classification:

G06F 9/44

US Classification:

717108

Abstract:

A high level language for Mathematical Programming modeling is provided within a low level general purpose object oriented programming language. Libraries can be provided with a standard low level language enabling the use of the high level programming semantics in the low level programming environment. Using the libraries, the user can easily build complex Mathematical Programming models by using high level constructs while still taking advantage of the runtime efficiency and general purpose computing offered by the low level language. In an embodiment, operator overloading of a low level language is used to build semantics of a high level language.
