US Patent:

20100070735, Mar 18, 2010

Filed:

Nov 11, 2008

Appl. No.:

12/268879

Inventors:

Frank Chen - North Potomac MD, US
Yuan Rong - Shanghai, CN
Zhao Wei - Shanghai, CN

International Classification:

G06F 12/10
G06F 12/00
G06F 12/08

US Classification:

711206, 711202, 711E12001, 711E12059

Abstract:

Memory modules and methods of operating memory modules embed mapping information within blocks of memory cells to which the mapping information pertains. In particular, when a page is written for a logical data block, that page includes a snapshot of the current mapping information for that logical data block. In this manner, the last valid physical page of a logical data block will contain a physical/logical mapping of that block. Thus, instead of scanning every valid page of the memory device to rebuild the mapping information, the memory module may scan only for the last valid physical page of each logical data block. Once the last valid physical page is discovered for a logical data block, the latest mapping information for that logical data block may be read from that page.

Abstract:

Methods and apparatus facilitate data streaming in bulk storage devices by generating linked lists containing entries for both user data and metadata. These linked lists containing mixed data types facilitate receiving and outputting user data, and to insert or ignore, respectively, metadata corresponding to that user data without interrupting flow of the user data.

Filed:

Aug 6, 1976

Appl. No.:

5/712154

Inventors:

Frank T. Chen - Reston VA

Assignee:

Southern Pacific Communications Company (SPCC) - Burlingame CA

International Classification:

H04J 300

US Classification:

343204

Abstract:

Disclosed is a data transmission network having an improved interface unit for matching the network to local subscriber loops. It is particularly constructed for the translation of supervisory signals in private and switched line systems. A switched channel logic circuit comprising an assembler and parallel to serial converter is provided for each data channel and these circuits connect to a common logic circuit comprising a combiner in the form of a shifter and a matrix of shift registers.

Abstract:

A computer-implemented method is provided to visualize data related to one or more assets utilizing an interactive geospatial map. The system may receive query criteria, indicating a geographic region of interest and/or timespan of interest, and may access a plurality of datasets including a first dataset comprising data items associated with default locations of assets and a second dataset comprising data items associated with transit events of assets, and wherein the plurality of datasets are associated with geographic locations and respective times. The system may query the plurality of datasets to determine, for assets associated with the one or more data items, expected geographic locations of the assets, and may generate user interface data configured for rendering an interactive user interface including an interactive geospatial map with indications of the expected geographic locations of the assets, and a plurality of interactive tables.
