Patent CA-2575860-A1 (CA)
Inventor: GRUENKE ROGER A
IPC: A61B5/08
Filed: 1995-05-16
Abstract: In the treatment of obstructive sleep apnea, a method and apparatus (70) are disclosed for optimizing the controlled positive pressure to minimize the flow of air from a flow generator (86) while still ensuring that flow limitation in the patient's airway doest not occur. In particular, the invention relates to a breathing device (70) and method of use to adjust a controlled positive pressure to the airway of a patient by detecting flow limitation from analysis of an inspiratory flow waveform.  Once the presence of flow limitation has been analyzed the system determined an action to take for adjustment of the controlled positive pressure. The pressure setting is raised, lowered or maintained depending on whether flow limitation has been detected and on the previous actions taken by the system. The preferred breathing apparatus (70) consists of a flow generator (86), a flow sensor (72), an analog to digital converter (78), a microprocessor (80), and a pressure controller (82, 84), a patient supply hose (74), a nasal fitting, and, optionally, a pressure transducer (90). Using the method of the present invention, the microprocessor (80) adjusts the air pressure in the patient's supply hose (74) when flow limitation is detected in the airway of the patient.

Title: Procedure pour securiser les transactions bancaires

Abstract: Une méthode ou procédure pour éliminer la fraude des cartes de débits ou crédits. Ce processus révolutionne la manière de conserver vos informations personnelles qui éliminera le vol d'identité dans le domaine des cartes de crédit ou de débit. L'abonné contrôle en tout temps l'accès à sa carte de débit ou crédit. La clé de la réussite de ce procédé atteint un très haut niveau de sécurité lorsque le NIP (Numéro Identité Personnel) change pour chaque transaction. De plus le NIP que l'usager reçoit à chaque transaction a besoin d'une transformation que seul l'abonné a mémorisé pour être accepté. Avec ce procédé l'abonné a le plein contrôle des accès à son crédit sans que quelqu'un pirate son compte même s'il possède sa carte et le NIP de la dernière transaction. Dès que la dernière transaction a été acceptée le NIP a été désactivé jusqu'à la prochaine demande de l'usager ou il recevra sur son cellulaire ou autre mode de communication un message avec le nouveau NIP encrypté. Seul l'usagé peut le décrypté car lui seul connait la règle pour le décodé, cette règle de décryptage est confidentiel que vous avez choisi en personne à votre institution financière. Cette règle ne se promène jamais sur Internet et reste encodé dans votre compte dans les bureaux de votre institution financière. Voici quelques exemples simple de cryptage: 1- Additionné ou soustraire du NIP reçu (+10 ou -1), 2- Permuter deux nombres dans le NIP reçu (1234 pour 1243), etc. Ce procédé offre plusieurs façon de protéger votre NIP et d'accéder votre compte. Il est évolutif car pour les personnes ayant un GPS portatif ou inclus dans leur cellulaire, le système compare le positionnement de votre GPS avec celui ou la demande a eu lieu (guichet, terminal, etc.) avant d'autoriser la transaction.

Title: Mimic gauge for a chart recorder
Inventor: WESTMORELAND AUDREY DARE III
IPC: G06F17/40
Filed: 2007-07-20
Abstract: The present invention is directed to a data logger for electrically recording positions of a motional member in a chart recorder. A mechanical-to-electrical converter translates the mechanical positions into electrical position signals. The mechanical-to-electrical includes a mechanical coupler for securing at least a portion of the converter to a motional member in a mechanical chart recorder and a position sensor for measuring the spatial positions of the motional member as it moves in response to movements generated in a mechanical measurement instrument. The position sensor generates electrical position signals that are fed to a field processor.  The field processor transforms the electrical position signals into position data representative of the spatial position by applying a calibration algorithm that uses calibration coefficients determined for the particular position sensor being employed.  The position sensor may measure rotational movement, such as from a shaft in the chart recorder, or linear movement, such as from a linkage in the chart recorder.  Angular sensors include inclinometers, potentiometers, magnetic field sensors and optical sensors, while linear sensors include potentiometers, magnetic field sensors and optical sensors. Also provided in the field processor is storage capacity for storing data relating to the raw electrical signals or the measurement data, as well as for application software. Optionally, a transmitter may be incorporated in the field processor for transmitting the position information to a remote location.

Abstract: An improved controlled release composition for non-parenteral administration of active agents and other therapeutics, particularly for oral or topical administration, has been developed. The composition is made by dispersing a complex formed of an active agent bound to an ion-exchange resin or to another form of resin or carrier, in a non-ionic non-aqueous ("NINA") vehicle. The complexes are optionally coated with one or more layers of coating material to provide a controlled pattern of release of active agent from the carrier. The combination of multiple active agents is possible with this system, in which one or more active agents are bound to particles and one or more active agents are dissolved or dispersed in the NINA vehicle. This allows the combination of two or more active agents, which are otherwise incompatible, into a single dosage form.

Abstract: The present invention provides an audio source selection process for a conference bridge. The conference bridge receives multiple audio sources and selects at least one of the audio sources based on the relative signal levels associated with the audio signal at each of the audio sources. The audio signals associated with the selected source are delivered to conference participants via one or more audio outputs. The conference bridge will repeatedly employ a selection process to select an audio source based on signal level measurements for the audio signals of the audio sources. During the selection process, the influence of a selected audio source relative to the other unselected audio sources is reduced, after the selected audio source has remained selected for more than a first time period.

Abstract: A quantitative trait locus (QTL) affecting milk fat and protein concentration was localized to a 4cM confidence interval on chromosome 6 centered on the microsatellite BM143. The genes and sequence variation in this region were characterized, and common haplotypes spanning five polymorphic sites in the genes IBSP, SPP1, PKD2, and ABCG2 for two sires heterozygous for this QTL were localized. Expression of SPP1 and ABCG2 in the bovine mammary gland increased from parturition through lactation. SPP1 was sequenced, and all the coding exons of ABCG2 and PKD2 were sequenced for these two sires. The single nucleotide change capable of encoding a substitution of tyrosine-581 to serine (Y581S) in the ABCG2 transporter was the only polymorphism corresponding to the segregation status of all three heterozygous and 15 homozygous sires for the QTL in the Israeli and US Holstein populations.
