Title: Method and apparatus for generating packet data to support multiple services in a wireless packet data communication system
Inventor: MARKS ROBERT J
IPC: H04W92/10
Filed: 2004-07-14
Abstract: A packet data generating method and apparatus for supporting multiple services in a wireless packet data communication system where an MS transmits two or more traffics to a BS on one of a reverse PDCH, a reverse FCH, and a reverse DCCH. To generate a PDU using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, a multiplex option is determined during service negotiations between the MS and the BS. The multiplex option defines a traffic format having a header and a payload including traffic data, and the header includes a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data. A PDU is generated by formatting a reverse traffic to have a header and a payload according to the determined multiplex option.

Title: Configurable quality-of-service support per virtual access point (vap) in a wireless lan (wlan) access device
Inventor: TRUDEAU PIERRE
IPC: H04L69/14
Filed: 2006-01-25
Abstract: A wireless network access device includes a radio and support for virtual access points. According to the invention, each virtual access point has an independently configurable quality-of-service profile. The per-VAP QoS support enables multiple services to be delivered from a single physical access point.

Each queue in the plurality of queues is associated with a given quality-of-service level, such as (in decreasing order of priority): voice, video, best effort data, and background data. The access device further includes a data transfer mechanism in the form of a data packet forwarding engine that, for each VAP, transfers data from the plurality of queues to enforce the per-VAP QoS policy.
Patent CA-2534027-A1 (CA)
Title: Variants of human taste receptor genes
Inventor: DRAYNA DENNIS
IPC: G01N33/566
Filed: 2004-06-18
Abstract: Identified herein are different forms of bitter receptor genes that occur in different humans. These alleles are generated by numerous coding single nucleotide polymorphisms (cSNP's) that occur within the members of the T2R  gene family. Some SNP's cause amino acid substitutions, while others introduce chain termination codons, rendering the allele non-functional. Differences in these genes are believed to have a large effect on those individuals' sense of bitter taste, such that these individuals perceive the taste of bitter substances differently than the rest of the population. The ability to assay this allelic information is useful in the development of flavorings and flavor enhancers, as it can be used to define large groups and populations who perceive bitter tastes differently. This in turn allows the taste preferences of these groups to be addressed at the molecular level for the first time.

Patent CA-2545252-A1 (CA)
Inventor: PUBLICOVER NELSON G
IPC: C07H21/00
Filed: 2004-11-08
Abstract: The invention provides novel oligonucleotides and methods of using the same for detection or measurement of specific nucleic acid molecules. The invention also features nucleic acid arrays comprising the oligonucleotides of the invention. An oligonucleotide of the invention comprises (1) a reporter-binding sequence capable of hybridizing to a fluorrophore-labeled reporter sequence and (2) a hairpin-forming sequence capable of forming a stem-loop.  Formation of the stem-loop modifies (e.g., quenching) the fluorescence signals of the reporter sequence when the reporter sequence is hybridized to the oligonucleotide. This can be achieved, for example, by bringing one or more guanine based in the oligonucleotide into close proximity to the fluorophore(s) of the reporter sequence by virtue of the formation of the stem-loop. Disruption of the stem-loop, such as by hybridization of a target sequence to at least part of the hairpin-forming sequence, produces a detectable change in the fluorescence signals.
