Appl. No.:

10/099422

Inventors:

Ching Lan Ho - San Mateo CA, US

Assignee:

Oracle International Corporation - Redwood Shores CA

International Classification:

G06K 9/72
G06K 9/18
G06F 7/00

US Classification:

382229, 382185, 707 7

Abstract:

A method and system for context-based sorting of character strings. A first sorting weight of a current character of a character string is determined from a first table. The first sorting weight is stored. Provided the current character is a predetermined character, a second table is accessed. A second sorting weight of the current character is determined from the location of a preceding character within the second table. The first sorting weight is replaced with the second sorting weight for the current character. Embodiments of the present invention provide an efficient method of context-based sorting in languages, such as Japanese, where the sorting weight of a character can be altered by the preceding character.

Abstract:

An optical receiver communication system converts optical signals modulated by analog or digital waveforms to RF signals. The optical receiver contains an automatic level control circuit to adjust the electronic gain of the system accordingly across a broad bandwidth spectrum. Two impedance matching circuit are designed using broad band matching technique to expand the bandwidth for increasing the maximum receivable frequency to 1 GHz. A RLC impedance matching circuit forms a resonant combination to maintain. +-. 1 dB fluctuation between the low-and high-frequency limits of the bandwidth, and a 75. OMEGA. impedance matching circuit creates a 180. degree. phase shift between the outgoing and the incoming signal for low return loss.
