US Patent:

20080177701, Jul 24, 2008

Filed:

Jan 23, 2007

Appl. No.:

11/625960

Inventors:

Robert W. Merritt - Houston TX, US
Vickie K. Coulter - Brenham TX, US

Assignee:

TOTAL E&P USA, INC. - Houston TX

International Classification:

G06F 17/30

US Classification:

707 3, 707 6, 707E17014

Abstract:

A pathname-based index is constructed for use in searching for a file of interest that resides in a volume of files. Thus, information contained in the paths present in the volume of files (e.g., directories and subdirectories) is used for efficiently searching for a file of interest. According to certain embodiments, an indexing application searches a volume of files and retrieves information (e.g., metadata) about the files contained therein for storage to a database that can then be searched, rather than requiring the full volume itself to be searched. Further, the file information (e.g., metadata) is indexed in the database based on the files' respective pathname in the volume of files. Thus, information contained in the file's pathname can be utilized in searching the database for information about the file (e.g., for discovering the file as being of interest).

Appl. No.:

9/177874

Inventors:

Assignee:

Duke University - Durham NC

International Classification:

G03B 2126
G03B 2114

US Classification:

359649

Abstract:

Projection lenses and projection lens systems are telecentric between an illumination subsystem and a set of imagers. The lenses and systems can exhibit color fringing correction, uniform imager illumination, athermalization, and component articulation for improved imaging. The lenses and systems may be employed in display apparatuses, such as folded display apparatuses that have decreased footprint size, but long effective projection lengths.
