Abstract: Selon l'invention, la sécurité des réseaux sans fil est améliorée par rejet du trafic d'un dispositif sans fil situé à l'extérieur d'une limite spatiale définie. La position spatiale du dispositif par rapport à la limite est déterminée au moyen de réseaux d'antennes directionnelles situées sur une pluralité de points de mesure, et par calcul de la zone d'intersection des vecteurs. Après avoir déterminé la position d'un dispositif, l'accès à un réseau sans fil peut être refusé si ledit dispositif se trouve à l'extérieur d'une limite spatiale prédéterminée. Par ailleurs, que le dispositif se situe à l'intérieur ou à l'extérieur de la limite spatiale, sa position peut être utilisée pour la surveillance d'une position changeante d'un ou de plusieurs dispositifs clients dans un réseau dans fil, par exemple pour la détection de vol ou pour un mécanisme antivol.

Title: Improved process for isolation and purification of paclitaxel from natural sources
Inventor: POTIER MICHEL
IPC: C07D305/14
Filed: 2004-01-27
Abstract: Disclosed is a process for the extraction and purification of Paclitaxel from a natural source of taxanes containing Paclitaxel, which comprises the steps of: a) washing with deionized or pure water, a raw material comprising Paclitaxel, this raw material coming from a natural source of taxanes, such a washing allowing removal of soluble impurities from the raw material; b) extracting with an organic solvent from the washed raw material, a wet raw material comprising Paclitaxel; c) contacting the wet raw material with a salt to obtain a biomass by precipitation, and isolating and drying the biomass; d) removing resin and natural pigments from the so isolated and dried biomass by dissolving the biomass in acetone or an acetone-hexane mixture and then adding thereto at least one-polar solvent until a Paclitaxel-~enriched oil phase is obtained; e) purifying by chromatography at least once the Paclitaxel-enriched oily phase obtained in the preceding step in a volatile solvent to obtain a purified solution and crystallization at least once the purified solution obtained by chromatography. This process advantageously permits to reduce the impurities and the volume of the Paclitaxel and analogs extract which are obtained from the biomass by precipitation, to reduce the steps of purification, to increase the amount of Paclitaxel that is obtained; and to reduce the production cost to a more economical level.

Patent CA-2517345-A1 (CA)
Title: Messaging system
Inventor: MARSTON JUSTIN PHILIP
IPC: G06Q10/00
Filed: 2004-02-27
Abstract: A messaging system uses a relational model to represent messages exchanged among end-users of the system. A message within the system contains one or more submessages. A contents module stores data describing the content of each message and submessage. An attributes module describes the attributes possessed by the messages and submessages. A relationships module describes the relationships among the messages and submessages. Because submessages are separate from the messages that contain them, different policies can be applied to individual submessages. Moreover, the messaging system stores each object (e.g., message or submessage) only once. The messaging system thus significantly reduces infrastructure costs by removing unnecessary duplicity, and provides enterprises with the content granularity they need to enforce regulatory compliance and other policies.

Title: Portable air-conditioned air mattress
Inventor: BYRON MERV V
IPC: A47C27/08
Filed: 2006-03-30
Abstract: This invention is designed to create a portable air mattress which is temperature controlled via an air conditioning system. It utilizes a closed loop system of air conditioning for energy efficiency. The purpose of the mattress is to provide a more comfortable sleeping surface by keeping the mattress either warm or cool all night utilizing its own air-conditioning unit which consumes far less energy than an air-conditioning unit designed to heat or cool and entire house. The closed loop air conditioning system is achieved by passing the air from the AC unit through a corrugated tube which is sealed within the air mattress cavity, thereby passively heating the surrounding air, then back to the A/C unit with attachable lengths of corrugated tubing.

Abstract: A calibrator suitable for calibrating a noninvasive analyte detector, such as a Raman spectroscopy device, allows the user of the detection device to establish standard measurements of the analyte to be detected, thereby providing assurance that appropriate analyte measurements are obtained at the time of sampling. The calibrator is simple to use, making it suitable for home use by individuals regardless of medical or technical skill level. In particular, the calibrator can be used with a noninvasive glucose detection system, such as for monitoring of blood glucose levels in diabetics. For use with noninvasive detectors designed for obtaining measurements from a subject's fingertip, the calibrator can be formed into a shape that reasonably mimics a fingertip in size, texture and/or spectral properties.
