Title: Optical sensing devices
Inventor: PAINCHAUD YVES
IPC: G01N21/77
Filed: 2001-03-16
Abstract: An optical sensor is provided. The sensor includes an optical fiber having a free extremity on which a polymer layer is deposited normal to the longitudinal axis. A light source injects a analytical light beam in the fiber, which is reflected by the polymer layer. The reflected beam is analyzed by a spectrum analyzer, which determines the thickness of the polymer layer based on the Fabry-Perot effect. This thickness is related to a substance to be detected. An optical nose made from a plurality of such sensors is also provided, and may be used to detected a variety of substances.
Patent CA-2341492-A1 (CA)
Title: Holographic decorated tube package
Inventor: MCLAUGHLIN HEATHER LARKIN
IPC: B65D35/08
Filed: 1999-08-23
Abstract: The tube has a non-metallized holographic decoration. This holographic decoration is an inner layer (14) of the tube body which is of a laminate structure (16). The holographic film layer (14) is a non-metallized layer to prevent the delamination of the tube body when the tube body is formed with an overlap seal. In an overlap seal an edge of the laminate film potentially will be in contact with the contents of the tube (32). A metallized holographic layer can react with the contents of the tube (32) and cause a delamination of the film in the area of the seal and the consequent failure of the seal. The innermost (22) layer of the tube body will be a layer that is bondable to an outermost (12) barrier layer, and further that is bondable to the shoulder (30) of the tube. It should be bondable to the innermost layer in order to form the longitudinal seal of the tube body. It should be bondable to the shoulder since the primary bond of the shoulder to the tube body is of the shoulder to the innermost layer of the tube body. The innermost layer and the outermost layer preferably are polyene layers. Polyenes form good heat bonds, and in particular, polyene to polyene bonds. Therefore, it is preferred that in addition to the innermost barrier layer and the outermost layer, the shoulder also be comprised of a polyene.

Title: Thromboplastin reagents and methods for preparing and using such reagents
Inventor: GOLDFORD MARC
IPC: G01N1/10
Filed: 1999-10-07
Abstract: Disclosed are mammalian thromboplastin reagents and methods for preparing such reagents. The thromboplastin reagents are suitable for use in prothrombin-time (PT) assays, and offer improved sensitivities with acceptable PT-normal times.  Contaminating proteins -- particularly plasma clotting factors -- are separated from a thromboplastin solution by a membrane permeation protocol, in which the thromboplastin solution is exposed to a semipermeable membrane and clotting factors are allowed to pass from the thromboplastin solution through the membrane, while Tissue Factor is retained in the thromboplastin solution.  In a preferred method, one or more contaminating clotting factors are separated by diafiltration from a NaCl/Na3Citrate thromboplastin extract of mammalian tissue, and the purified thromboplastin extract is combined with Ca++ ions to form a thromboplastin reagent.

Abstract: A method of playing at a gaming table or on an electronic video gaming machine a player-versus-paytable five-card stud poker game utilizing the 20 royal cards and 4 number nine cards of the four card suits of a standard 52-card poker deck as a 24-card pinochle-poker deck of cards with player awards based upon predetermined amounts related to a paytable of winning five-card hands. Initially a "bet" wager is made by a players and from the pinochle-poker deck two cards are dealt face-down and three cards are dealt face-up to the view of the player. The player, after viewing the face-up cards, is permitted to stand on the "bet" wager or double or triple the "bat" wager after which the face-down cards are up-turned and may be used as community cards in the hand of the player.  The player's hand is evaluated to determine whether or not such hand is a winning hand with respect to a paytable of winning five-card hands with a winning hand paid off in accordance with the paytable.

Patent CA-2359715-A1 (CA)
Inventor: KUI HENRY K
IPC: G01N31/22
Filed: 2001-10-23
Abstract: A method and an apparatus for preventing reversion of the color of an indicator dye in a biological indicator is disclosed. The indicator dye changes color if viable microorganisms are present after sterilization, because acidic byproducts are formed when the microorganisms metabolize the growth medium. It has been found that the dye can change color back to the original color after the completion of the sterilization due to leaching or diffusion of basic impurities into the growth medium. The method and the apparatus employ a dual buffer system with one buffer which operates at high pH to moderate pH fluctuations at the start of the sterilization and a second buffer which operates at low pH to minimize pH fluctuations after the sterilization is complete. Less high pH buffer than low pH buffer is used in order to maximize the speed and sensitivity of the biological indicator.

Title: Flush controller
Inventor: JOHNSON DWIGHT N
IPC: E03D5/10
Filed: 2002-01-07
Abstract: A high flow valve assembly and a low flow valve assembly are in parallel flow relation between an inlet and an outlet of a flush controller housing. The valve assemblies are opened by solenoid operated pilot valves under the control of a microprocessor based flush control system. A turbine directly measures flow through the low flow valve assembly and the control system computes flow through the high flow valve assembly to perform a flushing operation including an initial siphon trap flushing high flow portion and a subsequent trap reseal low flow portion. A push button is pressed to one of two override positions either to provide a signal to the control system for a normal flush operation or to open the high flow valve assembly independently of the control system for an emergency flush operation. A user detection system includes a pair of emitters and a pair of detectors defining an array of intersecting detection points in a skewed plane in which the control system can locate the position of a user. The controller can be configured for supplying flush water for either a toilet or a urinal, and for either right or left side water supply entry.

Le système peut comprendre un serveur de synchronisation qui échange des détails de transaction avec des dispositifs clients, un serveur de communication qui inscrit les nouveaux usagers, un serveur financier pour interagir avec des institutions financières extérieures, et un serveur de sécurité pour assurer la sécurité des opérations d'échange de valeurs. Dans une forme d'exécution, une première partie engage une transaction sur un dispositif client (p. ex. un dispositif informatique mobile) en sélectionnant ou en entrant un identificateur (qui peut être préexistant, tel qu'un numéro de téléphone) d'une autre partie et une valeur à échanger. La transaction peut être conduite à un moment où les dispositifs clients des parties sont connectés électroniquement; elle peut aussi être conduite par un usager sur un dispositif. Les transactions sont communiquées à un serveur système pendant la synchronisation entre un dispositif client d'une partie et un serveur système.

Title: Position sensitive light spot detector
Inventor: BERALDIN J ANGELO
IPC: G01J1/02
Filed: 2000-04-27
Abstract: The present invention provides a method and an apparatus for detecting a position of a light spot in a light distribution that can include stray light components (e.g. from other lasers, ambient lighting etc.). The apparatus includes a continuous response position sensitive detector (CRPSD, e.g. lateral effect photo-diode) for determining a first centroid of the light distribution and a discrete response position sensitive detector (DRPSD, e.g. multiplexed array) for determining a second centroid of the light distribution within a reading window defined about the first centroid and within the light distribution. The second centroid represents the position of the light spot in the light distribution. This multiple stage approach exploits the high resolution and speed offered by traditional CRPSDs together with the accuracy under variable lighting conditions offered by traditional DRPSDs.
