Abstract: A structure and its method for manufacture for a switchable optical filter.  The structure comprises a substrate (10) transparent to the radiation of interest, which contains or supports an electrode (12). A spacer layer (16) suspends the membrane over the electrode (12) such that no spacer lies between the electrode (12) and the membrane (22), yet some spacer (16) remains elsewhere to support the membrane (22). The membrane has slots (24) in it which are of a specified length in order to resonate at a particular wavelength of radiation. When the electrode (12) is activated, the membrane (22) deflects and its varying proximity to the substrate changes the wavelength of transmission.

Abstract: Méthode thérapeutique permettant de moduler la réponse immunitaire en administrant à un patient une quantité d'IL-4 servant à promouvoir l'adhésion des lymphocytes du sang périphérique aux cellules endothéliales microvasculaires dans les organes lymphoïdes. L'IL-4 est administré de préférence en même temps que l'IL-1-bêta. L'invention a trait à une méthode améliorée de triage d'une lignée cellulaire pour la production d'un partenaire de liaison qui se lie à une molécule d'adhésion cellulaire; elle consiste à mettre le partenaire de liaison en contact avec des cellules endothéliales microvasculaires activées par IL-4 et non activées et à sélectionner des partenaires de liaison qui se fixent à des cellules endothéliales microvasculaires activées par IL-4 mais non à des cellules endothéliales microvasculaires non activées. On peut ensuite vérifier si les partenaires de liaison sélectionnés peuvent bloquer la liaison des lymphocytes aux cellules endothéliales activées par la cytokine. De préférence, les partenaires de liaison se lient également à VCAM-1 d'origine humaine et aux cellules du stroma de la moelle osseuse activées par IL-4 ou TNF-alpha. Un exemple représentatif est mAb 6G10 produit par l'hybridome ATTC no HB 10519. Méthode thérapeutique permettant de moduler la réponse immunitaire d'un patient en lui administrant un agent qui se lie spécifiquement aux cellules endothéliales microvasculaires activées par IL-4 à une concentration pouvant empêcher la transmigration de lymphocytes qui se lient spécifiquement à VCAM-1 dans le sang de veinules post-capillaires.
Patent CA-2088652-C (CA)
Inventor: YU YEUNG S
IPC: C12Q1/26

Granted: 2008-07-29
Abstract: A dye couple, comprising 3-methyl-2-benzothiazolinone hydrazone (MBTH) and 8-anilino-1-naphthalenesulfonate (ANS), is used as an indicator in a reaction cascade producing a strong oxidizing agent, such as hydrogen peroxide or other peroxides or perborates. The strong oxidizing agent reacts with the dye couple to produce a blue dye stuff. The MBTH-ANS dye couple exhibits strong and flat spectral absorption at the region of about 600 to 650 nm. This region is free of blood color interference, which enables one to measure glucose and other analytes that react with an oxidase enzyme to produce the strong oxidizing agent, through the use of LED optics, accurately without much optic calibration. Further, the MBTH and ANS are very soluble in aqueous solution, yet become insoluble upon oxidative coupling. The poor solubility minimizes dye fading, thus providing a stable endpoint.

Filed: 1994-01-11
Granted: 1998-06-16
Abstract: An automatic vehicle starter in which a temperature sensor may sense a temperature of the engine.  The vehicle starter may then remotely crank a starter motor of the vehicle.  The duration of time that the starter motor is cranked will be based on the sensed temperature.  In this way, a vehicle can be cranked for an appropriate amount of time without requiring any tachometer sensing operation.          Also, to insure that the vehicle has been properly started, after a signal to remotely start the vehicle is transmitted, a first battery voltage is measured.  Then, the ignition to the vehicle is turned on so that all turned on accessories will have power supplied thereto.  A battery voltage is then again measured, this battery voltage representing the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto.  The vehicle is then automatically started.  The battery voltage is then continuously measured and, if it determined that the battery voltage falls below a predetermined value, it will indicate that the vehicle has stalled.  The vehicle can then automatically be restarted to insure proper starting or can be turned off.

Granted: 2003-12-09
Abstract: Digital image data are compressed in a first iteration of orthogonally transforming a predetermined amount of the original image data, such as index data for a splite pattern, and quantizing the transform coefficients. Then the quantized data are locally decoded, and the decoded data are compared with the original image data. If there are no errors, that is, the decoded data matches the original image data, the quantized data are variable length encoded to form compressed data for output, such as recording on a CD-ROM recording medium. If there are errors, then a next iteration is performed, in which the original image data are bit shifted and then orthogonally transformed, the transform coefficients are quantized, and the quantized data are locally decoded. As before, the decoded data are compared with the original image data. If there are no errors, the quantized data are variable length encoded to form compressed data for output. If there are errors, then the original image data are further bit shifted in a next iteration, and the above described processing is repeated until there are no errors. The recorded compressed data are reproduced, variable length decoded, dequantized, inverse orthogonally transformed, inverse bit shifted, and used as picture data for display on a television.

Granted: 1999-10-05
Abstract: An accumulator (30) for an implantable infusion system employs a pair of separated diaphragms (47, 52) movable in unison by a transfer fluid disposed therebetween. A drug chamber (41) received infusate in metered amounts through inlet (42) and dispenses the contents as a function of a toggled valve operation. During filling, the first diaphragm (47) deflects upward and by pressure transfer causes a corresponding deflection in the second diaphragm (52). The second diaphragm (52) is biased by springs, gas under pressure or the like. Hence, when inlet valve (26) closes and outlet valve (28) opens, the pressure differential cross second diaphragm (52) causes downward deflection and fluid flows through outlet (44). No mechanical stops are needed in chamber (41) for the first diaphragm (47) since its movement is controlled by the pressure differential across the second diaphragm (52).
