Appl. No.:

09/306828

Inventors:

Thai D. Nguyen - Mill Valley CA

Pu Chen - Villiston VT
Hua Chen - San Francisco CA

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

C12Q 168

US Classification:

435 6, 435 911

Abstract:

In a preferred aspect of the invention, the upstream sequences of the TIGR protein encoding sequence can be used to diagnose a sensivity to steroids and a risk for glaucoma or ocular hypertensive disorders. Methods, kits, and nucleic acids containing polymorphisms, base substitutions, or base additions located within the upstream region and within protein-encoding regions of the TIGR gene are also provided. The upstream sequences disclosed, including the TIGR promoter regions and those regions possessing functional characteristics associated with or possessed by the TIGR gene 5âregulatory region, can also be used to generate cells, vectors, transgenic animals, and nucleic acid constructs useful in a variety of diagnostic and prognostic methods and kits as well as therapeutic compounds, compositions, and methods.

International Classification:

G10L019/00

US Classification:

704500, 704226

Abstract:

A multimedia decoder unit having error concealment and fast muting capabilities. The audio decoder provides error concealment using a dynamic recovery delay that is based on the error rate of an input digital bitstream and also uses frame repeating. The decoder allows fast audio muting whereby audio can be muted within two audio frames of a mute signal that immediately freezes the video frame, e. g. , a channel change. With respect to the dynamic recovery delay, a template of fixed length is used to inspect the last frames within the template. If error is found, then the error sum is used as an index into a table length which provides a dynamic template length. Error within the dynamic template length is computed and if larger than a tolerance, the current frame is muted. This allows the recovery delay to be adaptive and based on the error rate while still allowing mute merging. Muting the current frame can be achieved by repeating the previous frame but the delay data of the last block of the previous audio frame is added to the first block of the repeated audio frame to provide a smooth frame interface.

International Classification:

H04L 12/56

US Classification:

370419000, 370420000

Abstract:

The number of IP addresses required by a central office device, which is connected to a network segment and a number of customer internet devices to pass packets between the network segment and the customer internet devices, is reduced to one by using an IP address and a subnet mask that are associated with the network interface as a virtual interface. The subnet mask allows packets to be routed to the central office device, which then forwards the packets to the customer internet devices.

Abstract:

Information pertinent to an item or product may be organized (e.g., structured) as a property of the item or product. The property may be represented (e.g., stored) as property data in a data structure of the item or product. A property may have one or more properties of its own. In this manner, information pertinent to items, products, properties, or any suitable combination thereof may be structured with any level of sophistication or complexity. Accordingly, a data structure may be generated to contain one or more properties of an item or product, as well as to contain one or more properties of those properties. A “composite property” refers to such a data structure and may be indexed based on a value contained therein. The value may be used to identify the item or the product, for example, as an instance of a virtual product.

Abstract:

The nucleic acid upstream of the TIGR protein encoding sequence can be used to diagnose glaucoma. Polymorphisms, base substitutions, base additions located with the upstream and within TIGR exons can also be used to diagnose glaucoma. In addition, polymorphisms, base substitutions, base additions located with the upstream and within TIGR exons can also be used to prognose glaucoma.
