Patent CA-2408890-A1 (CA)
Title: System and methods for concealing errors in data transmission
Inventor: KANG HONG-GOO
IPC: G10L19/12
Filed: 2002-10-18
Abstract: The present invention provides a frame erasure concealment device and method that is based on reestimating gain parameters for a code excited linear prediction (CELP) coder. During operation, when a frame in a stream of received data is detected as being erased, the coding parameters, especially an adaptive codebook gain gp and a fixed codebook gain gc, of the erased and subsequent frames can be reestimated by a gain matching procedure. By using this technique with the IS-641 speech coder, it has been found that the present invention improves the speech quality under various channel conditions, compared with a conventional extrapolation-based concealment algorithm.

Abstract: Method and apparatus for congestion control in a wireless communication system. Individual target data rate values are assigned individual access terminals. The individual data rates of the access terminals are adjusted to achieve the corresponding individual target data rate values (208, 218). If the target values are not achieved within a predetermined number of iterations, the individual data rate is adjusted. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease (204), wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold.

Title: Method for detecting diseases caused by chromosomal imbalances
Inventor: DEUTSCH SAMUEL
IPC: C12Q1/6883
Filed: 2002-06-21
Abstract: The invention provides a universal method to detect the presence of chromosomal abnormalities by using paralogous genes as internal controls in an amplification reaction. The method is rapid, high throughput, and amenable to semi-automated analyses. In one aspect, the method comprises providing a pair of primers which can specifically hybridize to each of a set of paralogous genes under conditions used in amplification reactions, such as PCR.  Paralogous genes are preferably on different chromosomes but may also be on the same chromosome (e.g., to detect loss or gain of different chromosome arms). By comparing the amount of amplified products generated, the relative dose of each gene can be determined and correlated with the relative dose of each chromosomal region and/or each chromosome, on which the gene is located.

Title: Method and apparatus for storing and managing contacts in a distributed collaboration system
Inventor: EVDOKIMOV ALEXEI
IPC: G06F1/00
Filed: 2003-12-11
Abstract: In a distributed collaboration system, each user stores all contact information in a local contact store. Each subsystem that maintains contact information, such as a shared space or contact list, and thus serves as. a "source" for contact information would then store only information, such as a URL, that identifies a contact in the contact store. In order to insure that communications with a contact are not lost by a failure to receive contact communication information, the local contact stores are updated by means of bi-directional subscriptions. In particular, when information for a contact is added to a user's local contact store, a subscription message is sent to that contact. The subscription message contains the user's contact information and requests that the user be added to a subscription list for the contact.  Updated contact information is automatically sent to each person on the subscription list.
