Filed:

Nov 18, 1998

Appl. No.:

09/195129

Inventors:

Jian Zhou - San Jose CA, US
Jianxin Liu - Mountain View CA, US
Zhengran Li - Campbell CA, US

Assignee:

Zoran Corporation - Sunnyvale CA

International Classification:

G06F 17/00
H03F 5/00

US Classification:

700 94, 381103

Abstract:

A computer readable memory to direct a computer to improve the perceived audio quality of a speaker included in that computer. The computer readable memory stores a first, second and third set of instructions. The first set of instructions causes the computer to determine the speaker type. The second set of instructions causes the computer to select a set of default filter coefficients for a digital filter based upon the speaker type. Finally, the third set of instructions causes the computer to realize a digital parametric equalizer using a digital filter and the set of default filter coefficients. Thus, the digital filter alters the audio signal that is input to the speaker, thereby improving the perceived quality of the speaker.

US Classification:

382151, 382144, 382287, 382289

Abstract:

A method for processing wafers includes learning a first pattern at a de-skew site on a first wafer layer, saving the first patterns in a recipe for de-skewing wafers, learning a second pattern at the de-skew site a second wafer layer, and saving the second pattern in the same recipe for de-skewing wafers. Learning the first pattern may include determining a score of uniqueness for the first pattern. The method further includes finding the de-skew site on the second wafer layer using the first pattern before learning the second pattern. Finding the de-skew site includes determining a score of similarity between the first pattern and the second pattern. Learning the second pattern is performed when the score of similarity is less than a threshold value. A recipe for de-skewing wafers includes multiple patterns of a de-skew site of a wafer, wherein the patterns include a first pattern at the de-skew site on a first wafer layer and a second pattern at the de-skew site on a second wafer layer.

Assignee:

OmniVision Technologies, Inc. - Santa Clara CA

International Classification:

H04N 11/04

US Classification:

37524024, 37524027, 37524028

Abstract:

A computer readable storage medium has executable instructions to select a plurality of macroblocks in a video sequence to be coded as anchor macroblocks, the anchor macroblocks distributed across the video sequence and facilitating random access decoding of a portion of the video sequence. The video sequence is coded into a bit stream. Auxiliary information associated with the anchor macroblocks is generated. The auxiliary information associated with the anchor macroblocks is inserted in a supplementary section of the bit stream.

Abstract:

This specification relates to tracking phone calls related to online content items. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a probability that a call to a phone number resulted from a first interaction of a set of interactions. In general, another aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a rank score for an online content item, including for each call of a plurality of phone calls to the phone number, attributing the call to an online content interaction of a set of online content interactions; determining, using the rank score, whether to provide the online content item to a client device; and providing the online content item to the client device upon determining to do so using the rank score.

International Classification:

H04N 7/32

US Classification:

37524012, 375E07243

Abstract:

A computer readable storage medium has executable instructions to select a plurality of blocks in a video sequence to be coded as intra-coded blocks. Aggregate intra prediction costs are computed for each intra-coded block relative to a corresponding previous intra-coded block. An intra prediction mode is selected for each intra-coded block based on the aggregate intra prediction costs.

US Classification:

37524015, 375E07126

Abstract:

A computer readable storage medium has executable instructions to select a plurality of blocks in a video sequence to be coded as intra-coded blocks. Intra prediction modes are selected for all intra-coded blocks in a macroblock based on original pixels of neighboring blocks. The mode selection of all intra-coded blocks can be conducted in parallel. The intra-coded blocks in the macroblock are predicted with the selected intra prediction modes based on reconstructed pixels of neighboring blocks.
