Patent CA-2377491-A1 (CA)
Title: Assay for degp protease inhibitors
Inventor: EVANS AMY K
IPC: G01N33/573
Filed: 2000-06-29
Abstract: The DegP (HtrA) protease is a multifunctional protein essential for the removal of misfolded and aggregated proteins in the periplasm. The present invention provides an assay for inhibitors of DegP activity, comprising mixing a suspected inhibitor of DegP activity with DegP and a suitable substrate (preferably a native substrate of DegP such as PapA) and detecting changes in DegP  activity. DegP has been shown to be essential for virulence in several Gram negative pathogens. Only three natural targets for DegP  have been described: colicin A lysis protein (Cal), pilin subunits (K88, K99, Pap) and recently HMW1 and HMW2 from Hemophilus influenzae. In vitro, DegP has shown weak protease activity on casein and several other non-native substrates. The present inventors have identified the major pilin subunit of the Pap pilus, PapA, as a native DegP substrate and demonstrated binding and proteolysis of this substrate in vitro. Using an NH2-terminal affinity tag the present inventors have purified PapA away from the PapD chaperone, in the presence of denaturant, to use as a proteolysis substrate. This finding will allow the identification of the DegP recognition and cleavage sites in substrate proteins, and further, allow the design of small molecule inhibitors of protease function.

Title: Method for improving the coding efficiency of an audio signal
Inventor: OJANPERA JUHA
IPC: G10L19/18
Filed: 2000-07-05
Abstract: The invention relates to a method for improving the coding accuracy and transmission efficiency of an audio signal. According to the method, a part of the audio signal to be coded is compared with earlier stored samples of the audio signal and a reference sequence of samples that best corresponds to th e audio signal to be coded is identified. Predicted signals are produced from the reference sequence by means of long-term prediction, using at least two different LTP orders (M), a group of pitch predictor coefficients (b(K)) bei ng formed for each pitch predictor order. The predicted signals for each pitch predictor order are compared with the audio signal to be coded in order to determine a prediction error. The amount of information required to code the  predicted signals is compared with the amount of information required to cod e the original signal and a coding method that provides the best representatio n of the audio signal while minimising the amount of data required is selected .

Title: Essais relatifs a l'evaluation de risque d'episode thrombotique reposant sur l'utilisation de phospholipides oxydes
Inventor: ESMON NAOMI L
IPC: G01N33/49
Filed: 2000-09-26
Abstract: L'invention concerne des essais relatifs à l'évaluation de risque d'épisode thrombotique, qui reposent sur l'utilisation de lipides oxydés renfermant des phospholipides comme source de membrane, en essai de coagulation. On compare les résultats avec ceux d'un essai dans lequel des phospholipides sont utilisés comme source de membrane avec et sans protéine C activée ("APC"). On peut ainsi contrôler chez un patient la présence d'anticorps qui interfèrent spécifiquement avec la fonction d'anticoagulant de l'APC, en scénario de dépendance ou d'indépendance par rapport à l'oxydation. Il en découle une indication sur les risques encourus par le patient quant à la survenue d'épisodes thrombotiques veineux ou artériels.

Abstract: A flexible product distribution and payment system for computer network based electronic commerce is disclosed. Primary content data is made available to customers through a detachable local storage medium, such as a DVD or CD-ROM  disc, or over a network connection. The primary content is capalbe of being accessed and played back through a computer or game console at the customer site. The primary content distribution may comprise a superset of content that is intended to be used by the customer. The customer is allowed to view and access the encoded primary content, and is charged only for the primary content that is used. Content that is encoded on the medium but that is not used by the customer remains on the medium but is not charged. A content database and customer database maintained at the primary customer site maintain records or products ordered and used by the customer, as well as identification and use patterns associated with the user. Authentication and use trigger data associated with the distributed content alert the primary content server computer when customer use has occurred and when a charge to the customer is appropriate.

Patent CA-2405399-A1 (CA)
Title: Retrieving and processing stored information using a distributed network of remote computers
Inventor: LEWIS TIMOTHY GRANT
IPC: H04L29/08
Filed: 2001-04-18
Abstract: A system retrieves and processes information stored on computers connected by a communications network. A central computer receives notification from a remote computer that the computer is available to receive data. In response to that notification, the central computer sends address data to the remote computer. To utilise the available network resources with maximum efficiency, the central computer optimises performance of the distributed system by allocating address data to the remote computer based on at least one characteristic of the remote computer, such as a measure of network connectivity and/or on a performance characteristic of that remote computer.  This allocation may take place in accordance with the relative importance of the data for indexing purposes. The remote computer uses a communication interface connected to the Internet to retrieve the information stored at the locations specified by the address data, and stores that information. The remote computer then processes the retrieved information to generate processed data, and stores the processed data. Finally, the remote computer sends the processed data to the central computer.
