Title: Nerve stimulation method and apparatus for pain relief
Inventor: FITZ WILLIAM R
IPC: A61N1/34
Filed: 2000-01-10
Abstract: Methods, and apparatus are disclosed for stimulating the central, peripheral , and autonomic with particular attention being given to the medial branch (21 0) of the spinal nerve (212) associated with a painful spinal facet joint so as  to block pain impulses from reaching the spinal cord. The preferred apparatu s includes a neurostimulator (204), and two or more electrodes (206) which car ry electrical pulses to the target nerves. The impluses are intense enough to cause stimulation of a given medial branch (210), and its articular branches , but not so large as to spread to the spinal cord itself. In the preferred embodiment the stimulator (204) is physically small and battery operated facilitating implantation underneath the skin. The stimulator (204) includes  a controller (not shown), and appropriate electronics operative to generate electrical impulses tailored to an individual's need for appropriate pain relief in terms of pulse frequency, pulse width, and pulse amplitude. In an alternative embodiment, the stimulator (204) further includes electrodes (206), and electrical circuitry operative to monitor myoelectrical activity generated by the surrounding muscles, and modulate the impulses generated by  the stimulator to meet the demands of the individual's activity and/or prolo ng battery life.

Title: Classification of data for insertion into a database
Inventor: ZHU BIAO
IPC: G06F16/16
Filed: 2002-04-29
Abstract: Records of information are classified for delivery to different targets or destinations even though it is not predictable as to which target a given unit of data (such as a record) should be routed. Classification allows database updating through an insert command. Generally, it cannot be predicted into which table a given record should be inserted when there are multiple tables or destinations from which to choose.

Abstract: A color shifting multilayer interference film is provided which may be used to produce foils or flakes for use in pigment compositions and colorants having color shifting properties. The flakes can be interspersed into a pigment medium to form paints, inks, or cosmetic preparations which can subsequently be applied to objects, papers, or people. Three and five layer designs of the interference film include alternating layers of a dielectric material and carbon in various configurations. The dielectric layers are formed to have an optical thickness at a design wavelength that provides a color shift as the angle of incident light or viewing angle changes.
Patent CA-2392546-A1 (CA)
Inventor: ROSDIANA EVA
IPC: H04N7/24
Filed: 2000-11-27
Abstract: Cette invention a trait à la commande d'un système à mode de transfert asynchrone (MTA) ou d'autres systèmes utilisant une transmission à débit binaire disponible. Une source de données est mise en mesure de transmettre à un certain débit binaire établi par le réseau en fonction de la capacité disponible. Lors de la transmission d'images télévisuelles, il est possible de commander le débit binaire réel par modification du degré de compression appliqué par le codeur vidéo (ou le transcodeur). Les modes opératoires existants permettant de diviser la capacité disponible entre des sources vidéo concurrentes se sont révélés insatisfaisants s'agissant d'atteindre une qualité égale d'image pour chaque source. Dans le cadre de cette invention, chaque source calcule une mesure de complexité d'image et le réseau (par exemple, un réseau de connexion MTA) utilise un dispositif lui permettant de calculer comment partager la capacité disponible.

Title: Iv pole
Inventor: CHINN ROBERT C
IPC: A61M5/14
Filed: 2001-03-23
Abstract: IV pole having mounted at an upper end a holding assembly comprising a head and a plunger, and at a lower end a docking assembly. The head on an upper portion includes at least two opposed upwardly extending projections suitably for hanging IV fluid containers. The plunger is movable between an extended position in which the plunger is held a distance above the height of the projections, and a retracted position in which the plunger is proximate to the projections such that removal of IV fluid containers hung on the projections is prevented. The smooth profile of the head and plunger greatly reduces the risk of the IV pole getting snagged on an obstruction or causing injury to rescue personnel. The docking assembly permits the IV pole to be removably secured to a docking port provided to a structural member and to be lowered to a stowed position.

Abstract: A process is disclosed for purifying a gas stream containing a contaminant gas and an energetic gas. The process comprises the steps of: a) providing a bioreactor comprising:-a reaction chamber containing a solvent and a biocatalyst capable of catalyzing a transformation reaction of said contaminant gas dissolved in the solvent into ions. The process further comprises the step of b) extracting the contaminant gas from the gas stream, which extraction comprises feeding the gas stream in the reaction chamber and thereby allowing the contaminant gas to dissolve and transform into ions, yielding said energetic gas free of said contaminant gas and leaving a spent solvent containing said ions in solution. Then, in step c) the energetic gas and the spent solvent obtained in step b) are separately released from the reaction chamber. The process further comprises the steps of d) removing the ions from the spent solvent to recycle the solvent; and e) feeding the recycled solvent of step e) in the reaction chamber. This process can advantageously be used to purify biogas and natural gas which contain methane as the energetic gas and carbon dioxide as the contaminant gas.

Le degré d'assèchement des boues digérées en excès est régulé en fonction de la quantité d'eaux usées problématiques à traiter. Lors de l'assèchement des boues de digestion, le filtrat récupéré qui contient la plus grande partie de la fraction azotée des eaux usées problématiques, est introduite dans la zone de traitement aérobie de la station d'épuration et y est soumis à la nitrification/dénitrification.

Title: Multiple channel magnetostrictive micropump
Inventor: ENGLISH MICHEL
IPC: A61M5/168
Filed: 2003-02-13
Abstract: A multiple piston magnetostrictive micropump (1) is disclosed for pumping fluid from multiple intake ports (2,8,14,20) to multiple delivery ports (7,13,19,25) at low volumes and controlled flow rates. The pumping action is achieved by the coordinated sequential strain of magnetostrictive actuators (3,4,5,6) into cavities (29,30,31,32). The coordinated sequential strain of the magnetostrictive actuators (3,4,5,6) creates unidirectional flow of the fluid from one cavity to the next cavity until the fluid is delivered at delivery ports (7,13,19,25). The magnetostrictive actuators (3,4,5,6) preferably are of the FeDyTb elements composition type known as Terfenol-D magnetostrictive materials providing greater magnetostriction and are isolated from the cavities (29,30,31,32) by thin seal layer (33). It is a further intent of this invention to provide accurate fluid volume mixtures at controlled flow rates by means of micromachined passage ways (27) embedded into micropump header (26).
