Patent CA-2381369-C (CA)
Title: One-step synthesis and consolidation of nanophase materials
Inventor: CHARLOT FREDERIC
IPC: B22F1/054
Filed: 2000-08-11
Granted: 2008-10-21
Abstract: Solid reaction products with a dense nanocrystalline structure are formed from reactant particles with diameters in the nano-scale range by compacting the particles into a green body, then passing an electric current through the body causing Joule heating sufficient to initiate the reaction to form the reaction product while simultaneously applying pressure to the reacting body to densify it to a density approaching the theoretical density of the pure product. Surprisingly, this process results in a reaction product that retains the nanocrystalline structure of the starting materials, despite the fact that a reaction has occurred and the materials have been subjected to highly stringent conditions of electric current, heat and pressure.

Title: Suds detection and display system for an automatic washing machine
Inventor: VANDE HAAR EVAN R
IPC: D06F39/06
Filed: 2002-06-21
Granted: 2006-01-31
Abstract: A clothes washing machine is automatically responsive to indications of high suds level conditions during washing operations to, not only counteract the high level of suds, but effectively educate the user on avoiding the reoccurrence of the conditions. A display, such as an LCD touch screen which is also preferably used to input desired cycle parameters, is integrated into the washing machine for both alerting the user to the occurrence of a high suds level condition and conveying information on how to avoid the development of the situation in the future. In order to avoid prematurely alarming the user, it is preferable to instruct the user only after a predetermined number of high level suds cycles are detected.

Abstract: Codeur à chiffrement sélectif muni d'un identificateur de paquets d'un type particulier qui fait partie d'un programme. Un duplicateur de paquet reproduit lesdits paquets pour produire une première et une seconde répliques des paquets identifiés. Un inserteur de tables de correspondances des programmes (PMT) génère des informations d'identification temporaires qui, comme le nom l'indique, identifient la première et la seconde séries de paquets identifiés et insère les informations d'identification temporaires à titre de données de l'utilisateur privées dans une table PMT qui fait partie des informations propres à un programme (PSI) de transport. Les données sont alors transmises vers un codeur de chiffrement primaire afin de chiffrer la première série de paquets identifiés selon une première méthode de chiffrement. Un codeur secondaire chiffre la seconde série de paquets identifiés selon une deuxième méthode de chiffrement. Les informations PSI sont alors modifiées en tant que modificateur PSI afin d'éliminer les informations d'identification temporaires et d'associer correctement la première et la seconde séries de paquets identifiés et les paquets non chiffrés au programme.

Filed: 2002-08-07
Granted: 2010-10-26
Abstract: A folded Sagnac fiber optic sensor array uses a common delay path to reduce distributed pickup in downlead fibers. The sensor array is used to detect perturbations (eg., acoustic waves in water). By basing the folded Sagnac sensor array on operating principles similar to the Sagnac interferometer the sensor array has a stable bias point, has a reduced phase noise, and allows a broadband signal source to be used rather than requiring a more expensive narrowline laser. A large number of sensors can be multiplexed into the architecture of the sensor array. In one particularly preferred embodiment, the sensor array is configured with couplers (2024) and amplifiers (2022) selected to direct substantially equal portions of an input light signal to each sensor array. In another particularly preferred embodiment, first and second delay paths are provided for light at first and second wavelengths (2210 & 2212) to increase the dynamic range of the sensors.
