Patent CA-2130339-C (CA)
Title: Antibacterial coated medical implants
Inventor: RAAD ISSAM I
IPC: A61M25/00
Filed: 1993-03-04
Granted: 2001-02-13
Abstract: An implantable medical device having long lasting resistance to staphylococcal biofilm colonization is provided. Implantible medical devices such as catheters, shunts, prosthesis, pacemakers, etc, are susceptible to colonization by biofilm adherent microorganisms, especially staphylococci. While systemic staphylococcal infections are effectively treated by many antibiotics, vancomycin being the antibiotic of choice, this same bacteria when encased in biofilm adhering to indwelling medical devices is generally resistant to antibiotic treatment. By the present invention, the combination of rifampin and minocycline or the combination or rifampin and novobiocin when coated on the surfaces of implantable medical devices unexpectedly provides superior antibacterial activity against staphylococcal biofilm colonization on the coated surface of indwelling medical devices.
Patent CA-2133861-C (CA)

Granted: 2004-03-30
Abstract: The invention is relative to a preparation in a novel indication which reduces the formation of deposits of thrombocytes in the vascular system. This prevents the occurrence of constrictions in the vessels. The preparation is alpha-lipoic acid (thioctic acid), which can be administered in several forms of administration such as e.g. by injection or by tablet and which is largely free of side effects.      Moreover, it can be shown in the case of smokers that the substance has a prophylactic effect in that the typical supersensitivity of the thrombocytes, which constitutes a cause for the appearance of premature vessel changes, is braked.

Abstract: A remote elevator monitoring system includes a master associated with a building and a local connected to the master. The local includes an electronic processor which executes instructions for determining whether the master has transmitted a signal packet to the local within a time period selectable at will by an operator at the local. The time period is, for example, a period selected within a range of 0-255 days. Optionally, for example, the master is programmed to transmit a signal packet to the local at a selected time on the last day of the selected time period.

Abstract: Novel 1,2-dioxetanes with improved chemiluminescent properties, such as signal intensity, S/N ratio, T1/2, etc. are provided by spiroadamantyl 1,2-dioxetanes, wherein the remaining carbon atom of the ring bears an alkoxy, aryloxy, or arylalkoxy substituent, and either a phenyl or naphthyl ring, this aromatic ring bearing, at the meta position on the phenyl group, or a non-conjugated position on the naphthyl ring, an OX moiety wherein X is an enzyme-clevable group, which when removed from the dioxetane, leaves the oxyanion which decomposes with chemiluminescence, the aryl ring further bearing an electron-active substituent Z. The nature and placement of the Z substituent, at a position not adjacent the point of attachment to the dioxetane ring, strongly influences the properties of the dioxetane. Assays, as well as kits for the performance of those assays, include the dioxetane, an enzyme capable of cleaving the X group, and in certain cases, membranes and chemiluminescent enhancement agents.

Abstract: An optical device (10) for collecting light and selectively outputting or concentrating the light. A wedge layer (12) has an optical index of refraction n1, and top (14), bottom (16) and side surfaces (18) intersecting to define an angle of inclination d. A back surface 20 spans the top (14) bottom (16) and side surface (18). A first layer is coupled to the bottom surface (16) of the layer (28) and has an index of refraction n2. The first layer (28) index n2 causes light input (22) through the back surface (20) of the layer to be preferentially outputted in the first layer. A second layer (30) is coupled to the bottom of (16) of the first layer (28) and selectively causes output of light into ambient. Additionally layers such as an air gap (31), can be provided adjacent to the wedge shaped layer. The wedge shaped layer can also have a variable index of refraction n (x, y, z).

Abstract: Une carte d'authentification comprend un affichage à cristaux liquides (107) agencé de façon à présenter une séquence de code à barres (230) à variation dynamique qui représente un numéro de compte (217) et, éventuellement, un numéro d'identification personnel (PIN) (219) et/ou une date d'expiration. La carte comprend un circuit permettant de changer périodiquement le code à barres en fonction d'un algorithme prédéterminé (214). Lorsque, la carte est présentée par un utilisateur à un commmerçant afin d'authentifier l'identité de l'utilisation dans le cadre d'une transaction commerciale, le code à barres est lu par un lecteur de code à barres classique. Le code est converti sous une forme électronique et transmis à un processeur de vérificateur afin d'être authentifié. Au cours de l'authentification, un algorithme correspondant est utilisé pour valider les informations provenant du signal reçu, permettant ainsi à une interrogation effectuée auprès d'une base de données de déterminer la validité de la carte. La carte peut avantageusement être produite à grande échelle et à un faible coût, et un lecteur de code à barres communément disponible fournit une interface simple lorsque la carte est présentée pour être authentifiée.

Abstract: Des lecteurs de formes de données et des procédés associés font appel à une séquence de périodes d'exposition par chevauchement pour des lignes successives d'éléments de détection faisant partie d'un réseau. De plus, les périodes d'exposition pour des lignes successives d'éléments de détection, ou des sous-ensembles de lignes successives, peuvent être déterminées indépendamment. Lors de la mise en marche d'un lecteur de formes de données, l'éclairage d'une zone cible (210) est déclenché avant l'exposition de la première ligne d'éléments de détection (222A), chaque ligne d'éléments de détection étant exposée à un éclairage par réflexion pendant une période d'exposition qui se chevauche avec la période d'exposition d'au moins une autre ligne, puis l'éclairage est éteint (228). A l'aide d'une structure MOS complémentaire, par exemple, une table de consultation renvoie au niveau des signaux d'image lus à partir d'une ligne d'éléments de détection afin de déterminer une période d'exposition appropriée pour une ou des lignes suivantes d'éléments faisant partie d'un réseau. Ce procédé se répète jusqu'à achèvement des périodes d'exposition réglées pour des conditions d'exposition localisées pour chaque ligne successive ou sous-ensemble de lignes d'éléments de détection.

Granted: 2002-01-29
Abstract: In CDMA mobile communication of the packet switching mode which is one-way, the packet is transmitted to divide to a frame unit. In this time, the first, the second and the third transmission timing which are obtained to divide to three pieces the predetermined frame are set up for increasing the transmission efficiency by realizing the retransmission of the frame unit, as the transmission timing of a backward control signal in a backward channel, Base station 100 transmits a forward signal (a forward control signal and an user data signal) by using code A (a forward channel) at any frame. When the forward signal is received at this frame by mobile station 70, mobile station 70 transmits a receiving acknowledgment signal (a backward control signal) of the forward signal by using code A' at the first transmission timing of the next frame. Conversely, when the forward signal is not received correctly, mobile station 70 transmits a retransmission request signal (the backward control signal) of the forward signal by using code A' at the first transmission timing of the next frame. The similar operation carries out in mobile stations 80 and 90. However, in this case, the transmission timing of the backward channel is the second or the third timing.

Granted: 2001-10-02
Abstract: A fluid is circulated through a region of single magnetic polarity within a complex magnetic field and with increased exposure time as compared to prior  art devices. The fluid travels through a coil of tubing arranged between two  magnetic fields that interact to form the region of single polarity. In a preferred embodiment, the fields are generated by two sets of magnets, one o n the inside of the coil and one on the outside of the coil. The magnets are arranged such that like poles of all the magnets face the tubing in the coil , creating the region of single polarity. Treating fuel or recirculated exhaus t gases prior to burning in internal combustion engines results in improved engine output characteristics.
