Appl. No.:

11/659918

Inventors:

Dong Li - League City TX, US
Jin Guo - Cupertino CA, US

International Classification:

H03K 17/94

US Classification:

341022000

Abstract:

The present invention provides a sensing keypad of a portable terminal and its controlling method, comprising: placing at least one sensing unit in the keypad area of the portable terminal to form a sensing surface; placing at least one sensing key on the said sensing surface; when a sensing object moves on the said sensing surface, the said at least one sensing unit generates multidimensional coordinates signal corresponding to trajectory of movement of the said sensing object and makes the said portable terminal to scroll through a list of menu items and to highlight one of them as indication of selection; when the said sensing object further press down a sensing key, the said sensing key generates a corresponding ON/OFF switch signal and makes the said portable terminal to confirm the said selection of the said highlighted menu item. The important benefits of the present invention are: it provides this new menu item scrolling and selecting function while keeping the original physical size of the mobile handset and original functionality of the digit keypad of the mobile handset intact.

G06K 9/62
G06N 20/00

Abstract:

An intelligent data management system leverages heterogeneous database technologies and cloud technology to manage data for reservoir simulations across the lifetime of a corresponding energy asset(s) and facilitates access of that data by various consumers despite changing compute platforms and adoption of open source paradigms. The intelligent data management system identifies the various data units that constitute a reservoir simulation output for storage and organization. The intelligent data management system organizes the constituent data units across a file system and object database based on correspondence with different simulation run attributes: project, study, and model. The intelligent data management system also learns to specify or guide configuration of simulation runs.

Abstract:

A method for estimating the wear of a drilling tool is disclosed. The method includes selecting a first incremental distance along a length of a formation. The method further includes determining a first characteristic of the formation along the first incremental distance. The method further includes deriving a first fractional wear factor, y, for the drilling tool based on the first characteristic of the formation and a first operating condition of the cutting element. The method further includes calculating a first wear function, W, the cutting element based on the first fractional wear factor and estimating an amount of wear of the cutting element during a drilling operation based on the first wear function.
