Patent CA-2465359-A1 (CA)
Title: Blind source separation of pulse oximetry signals
Inventor: STETSON PAUL F
IPC: A61B5/1455
Filed: 2002-10-31
Abstract: A method and apparatus for the application of Blind Source Separation (BSS), specifically Independent Component Analysis (ICA) to mixture signals obtaine d by a pulse oximeter sensor. In pulse oximetry, the signals measured at different wavelengths represent the mixture signals, while the plethysmographic signal, motion artifact, respiratory artifact and instrumental noise represent the source components. The BSS is carried out b y a two-step method including an ICA. In the first step, the method uses Principal Component Analysis (PCA) as a preprocessing step, and the Principa l Components are then used to derive sat and the Independent Components, where the Independent Components are determined in a second step. In one embodimen t, the independent components are obtained by high-order decorrelation of the principal components, achieved by maximizing the sum of the squares of the higher-order cumulants of the plurality of mixture signals.

Title: Dispositif de distribution osmotique dote d'une valve bidirectionnelle et a reglage automatique dynamique de canal d'ecoulement
Inventor: SCOTT JAY GILBERT
IPC: G05D7/01
Filed: 2002-11-21
Abstract: L'invention concerne système de distribution implantable, à entraînement osmotique comprenant une valve bidirectionnelle, à réglage automatique et à canal d'écoulement fluidique à géométrie variable. Lorsque la pression augmente dans le système de distribution d'agent, le canal fluidique se rétrécit, ce qui réduit l'écoulement. A des pressions exceptionnellement élevées, la valve peut être conçue de façon à se fermer complètement au niveau de l'orifice ou de l'extrémité de distribution, ou à laisser un passage de fuite minimum de sorte qu'un écoulement fluidique maximum n'est jamais dépassé. A des pressions basses ou nulles, la soupape se ferme complètement au niveau de l'extrémité du réservoir d'agent bénéfique, protégeant ainsi la formulation d'agent bénéfique contre une infiltration fluidique extérieure, ce qui empêche la diffusion d'un fluide extérieur dans ladite formulation d'agent bénéfique.

Filed: 2005-05-05
Abstract: An improved low energy extraction process for recovering bitumen from oil sand whereby essentially all of the thermal energy input for processing the oil sand takes place at the slurry mixing step as opposed to at both the slurry mixing step and the slurry flooding step. Mined oil sand is mixed with sufficient hot slurry water to produce an oil sand slurry having a density in the preferred range of about 1.50 g/cc to about 1.60 g/cc and a temperature in the preferred range of about 40°C to about 55°C, more preferably greater than about 43°C. The oil sand slurry is conditioned, preferably by pumping it through a pipeline for a sufficient length of time, and then flooded with cold flood water to produce a diluted slurry having a density in the range of about 1.4 g/cc to about 1.5 g/cc and a temperature generally below 40°C and typically in the range of about 30°C to about 35°C. The diluted slurry is introduced into a gravity separation vessel where bitumen froth is recovered.
