Patent CA-2364323-A1 (CA)
Inventor: BURKE STEPHEN RICHARD
IPC: F02D35/00
Filed: 2001-12-04
Abstract: The present invention provides a method and system for determining "engine on" status in a Hybrid Electric vehicle.      A controller determines the engine is necessary and then checks the current "engine on" status. If the engine is not currently running, the controller proceeds to start the engine by commanding the generator to spin or "motor" the engine.      The controller then starts fuel flow and spark within the engine to create combustion. A measuring device is then used to determine the crankshaft speed. The controller receives this measurement and determines whether the measured variations in crankshaft speed exceed a calibratable threshold. If the calibratable threshold is exceeded, combustion is determined to be occurring and the engine is on.      The controller then turns on the "engine on" status flag.

Title: A photonic crystal fibre and a method for its production
Inventor: RUSSELL PHILIP ST JOHN
IPC: C03B37/028
Filed: 2000-03-31
Abstract: This invention relates to an optical fibre that comprises a core (4) of lower refractive index that is surrounded by a cladding which includes regions of a higher refractive index and is substantially periodic, where the core (4) has a longest transverse dimension that is longer than a single, shortest period of the cladding.

Patent CA-2372802-A1 (CA)
Title: Emulsion-based processes for making microparticles
Inventor: TIPTON ARTHUR J
IPC: B01J13/12
Filed: 2000-05-02
Abstract: Processes for making microparticles, preferably containing an active agent, are provided. In a preferred embodiment, the process involves preparing (1) a dispersed phase containing an agent in a solution of polymer and a first solvent; (2) a continuous phase containing a surfactant, a second solvent that is totally or partially immiscible with the first solvent, and sufficient first solvent to saturate the continuous phase; and (3) an extraction phase that is a nonsolvent for the polymer, a solvent for the continuous phase components, and a solvent for the first solvent, wherein the first solvent has solubility in the extraction phase of between about 0,1 % and 25 % by weight. Then, the dispersed phase and the continuous phase are mixed to form an emulsion, and the emulsion is then briefly mixed with a suitable quantity of extraction phase to induce skin formation at the interface of the dispersed and continuous phases. Remaining solvent is removed by an evaporation process step. The emulsification and solvent removal steps are preferably conducted in a continuous process. The brief extraction step prior to evaporation minimizes the loss of active agent from the microparticles, and reduces the required volume of extraction phase as compared to other extraction-based processes. Alternate emulsification methods and solvent removal methods, such as incremental extraction, cryogenic extraction, or membrane separation, also are provided, and can be used in various combinations to make microparticles.

Title: Procede et dispositif d'activation d'horloge haute frequence suite a un mode de veille dans une station mobile fonctionnant en mode d'appel unilateral synchronise
Inventor: YU NICHOLAS K
IPC: H04M1/73
Filed: 2000-11-03
Abstract: L'invention concerne une technique d'activation d'horloge (102) haute fréquence de mode actif suite à une période de veille, s'utilisant dans une station mobile ; des éléments sélectionnés de la station mobile fonctionnent, pendant la période de veille, à l'aide d'une horloge (104) de mode veille faible puissance et basse fréquence, et, pendant les périodes d'activité, à l'aide d'une horloge (102) de mode actif plus rapide haute fréquence. Dans une forme de réalisation, la technique est mise en oeuvre par un dispositif comportant une unité (108) d'estimation d'activation servant à estimer un temps d'activation au moyen de l'horloge (104) de mode veille ; et une unité de compensation de dérive de fréquence servant à compenser toute erreur du temps d'activation estimé due à une dérive de fréquence de l'horloge (104) de mode veille. Une unité (112) de compensation de temps d'arrêt également prévue sert à compenser un manque de précision de l'horloge (104) de mode veille basse fréquence, susceptible d'entraîner une erreur du temps d'activation estimé. Le manque de précision peut entraîner une erreur d'arrêt de synchronisation initiale au début de la période de veille et une erreur d'arrêt de synchronisation finale à la fin de la période de veille. L'unité (110) de compensation de dérive de fréquence et l'unité de compensation de temps d'arrêt emploient un signal de synchronisation de mode de transition haute fréquence pour calculer le temps nécessaire au réglage du temps d'activation. L'horloge (106) de mode de transition, qui peut présenter la même fréquence que l'horloge (102) de mode actif, est employée seulement au début et à la fin de la période de veille, et est désactivée au cours de la plus grande partie de la période de veille afin de réduire la consommation d'énergie.
