Patent CA-2376671-A1 (CA)
Inventor: LIVOWSKY JEAN-MICHEL
IPC: G06Q30/02
Filed: 2000-04-14
Abstract: A system and method for enhancing e-commerce using a natural language interface. The natural language interface allows the user to formulate a query in a natural language form, rather than in conventional search terms. The natural language interface provides the user with a "user friendly" interface.  The natural language interface can process a query even if there is not an exact match between the user formulated search words and the content in the database. Furthermore, the natural language interface is capable of processing misspelled queries or queries having syntax errors. The method for enhancing e-commerce using a natural language interface comprises the steps of accessing a user interface provided by a service provider, entering a query using a natural language interface, the query being formed in a natural language, processing the query by the natural language interface, searching a database using the processed query, retrieving results from the database, and providing the results to the user. The system for enhancing e-commerce on the Internet comprises a user interface for receiving a query in a natural language form, a natural language interface coupled to the user interface for processing the query, a service provider coupled to the user interface for receiving the processed query, and one or more databases coupled to the user interface for storing information, wherein the system searches the databases using the processed query and provides the results to the user through the user interface.

Title: Fault location in a telecommunications network
Inventor: LOGAN HILARY PAUL
IPC: H04M3/08
Filed: 2001-03-29
Abstract: A fault is located along a telecommunications line between the network terminating equipment and the local exchange by measuring a change in the capacitance of the line when compared with the capacitance under normal operating conditions. A geographical information system is used to plot all possible routes for the line between the terminating equipment and the exchange, and the most probable route is selected based on the known positions of nodes along the line, such as pole mounted distribution points and streetside cabinets. The distance of the fault along the line is then plotted along the most probable route to determine an accurate fault location, which is given to a field technician as the location of the nearest premises or a grid reference.

Title: Process for preparing pharmaceutical compositions for use with soft gelatin formulations
Inventor: LEWIS JACQUELINE CAROL
IPC: A61K9/48
Filed: 2001-08-28
Abstract: The invention disclosed herein is a process for increasing the achievable concentration of a pharmaceutically active ingredient relative to fill composition viscosity for dosage units. The process is particularly useful in the preparation of soft gelatin capsules containing ibuprofen, naproxen, indomethacin, and acetaminophen, as the pharmaceutically active ingredient. As a result of the process, lesser quantities of composition ingredients other than the pharmaceutically active ingredient are needed to accomplish the same therapeutically effective dosage, thereby significantly increasing the concentration of the pharmaceutically active ingredient resulting in either a reduction in overall fill volume and dosage unit size or an increase in concentration of pharmaceutically active ingredient per dosage form.
