Title: Systeme pour secher des morceaux de bois
Inventor: LACOURSIERE YVES
IPC: F26B21/00
Filed: 2008-06-06
Abstract: L'invention est un récupérateur d'énergie qui sert à préchauffer l'air d'apport qui entre dans un séchoir à bois à partir de l'air chaud évacué. Le récupérateur est conçu de manière à ce que la température de l'air frais extérieur (air d'apport) soit préchauffée. L'effet généré par le préchauffage de l'air frais extérieur à travers le récupérateur d'énergie augmente le taux d'intégration de cette air (air d'apport) à l'air de circulation créant un mélange homogène et stable. Ce mélange crée une stabilité des conditions climatiques qui maintient le flux hydrique de la vapeur d'eau entre le bois et l'air qui circule le long des planches. Le micro climat créé par cet environnement améliore les performances de séchage sur un cycle complet pour la plupart des essences de bois. La vitesse générée par cet environnement permet de sécher plus rapidement en haut du point de saturation des fibres du bois que l'environnement crée par tous les séchoirs conventionnels connus sur le marché. Afin d'optimiser les performances thermiques du récupérateur d'énergie, ce dernier est fabriqué avec un écoulement de l'air de type à contre sens. Afin d' augmenter l'intégration de l'air d'apport préchauffé, l'air sera injecté dans l' air de recirculation via des orifices de pénétration.

Patent CA-2638756-A1 (CA)
Title: Optical dose measurements in syringes
Inventor: BROWN STEPHEN J
IPC: G01F3/16
Filed: 1997-07-22
Abstract: An apparatus for optically measuring and electronically recording a dose is disclosed. A holding means receives and holds a syringe, which has a barrel and a plunger, in a measurement position. A light source in optical communication with the barrel and the plunger generates light incident on the barrel and the plunger when the syringe is in the measurement position. An optical detector is positioned to detect a total amount of the light that is reflected from the syringe. A recording means in electrical communication with the optical detector records a dose datum indicative of the total amount of the light that is transmitted. The dose datum is indicative of the dose. A response enhancing element, connected with the plunger of the syringe and in optical communication with the optical detector, reflects light to the optical detector proportional to the dose datum.

Either way, however, the switch arm is operable to put the first and second switches sequentially into the both "off", one "off" and one "on", and both "on" states, regardless of the angle of the switch arm relative to the rotation axis.
Patent CA-2640332-A1 (CA)
Title: Perceptual image preview
Inventor: FENG WEI
IPC: G06T3/40
Filed: 2007-02-15
Abstract: Systems and methods for perceptual image preview are described. In one aspect, a naïve preview image is generated by downsampling a larger image. Perceptual features of the larger image are then detected. Information associated with the detected perceptual features is then incorporated into the naïve preview image to create a perceptual preview image. Since the perceptual preview image incorporates information associated with the detected perceptual features, a viewer of the perceptual preview image will be more likely to detect the presence or absence of such perceptual features in the larger image.

Title: Grouping of users for mimo transmission in a wireless communication system
Inventor: MALLADI DURGA PRASAD
IPC: H04L1/00
Filed: 2007-03-19
Abstract: Techniques for supporting MIMO transmission are described. User equipments (UEs) are classified into a first group of UEs to be scheduled individually and a second group of UEs that can be scheduled together. The classification may be based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, the number of UEs, etc. Channel quality indicator (CQI) information received from the UEs is interpreted in different manners depending on the groups to which the UEs belong. A single UE may be selected at a time from the first group or multiple UEs may be selected at a time from the second group for MIMO transmission. A MIMO transmission may be sent to a single UE in the first group or multiple UEs in the second group at rates selected based upon the CQI information.

Patent CA-2648032-A1 (CA)
Inventor: BEKURTS AXEL
IPC: B22D11/128
Filed: 2007-03-30
Abstract: The invention relates to a strand guide roller of a strand guide device for guiding a cast strand. The strand guide roller includes at least one first and one second sectional roller arranged next to each other, wherein the first sectional roller has a roller journal at its end surface adjacent to the second sectional roller. The strand guide roller includes a middle bearing, between both sectional rollers, for receiving and supporting the roller journal of the first sectional roller.  In order to improve strand guidance by increasing the bearing surface of the strand, it is suggested, according to the invention, that the first and second sectional rollers be connected with each other outside of the middle bearing by a plug-in connection. Then, according to the invention, the middle bearing is formed as unsplit separate bearing with an essentially smaller window width in comparison with a split bearing.

Patent CA-2649867-A1 (CA)
Title: Method for compensating for pressure differences across valves in cassette type iv pump
Inventor: HOLST PETER A
IPC: F04B49/08
Filed: 2000-12-15
Abstract: A pump used to infuse a fluid into a patient is controlled in accordance with an algorithm that enables a microprocessor (17) to monitor and adjust each pump cycle to compensate for a differential pressure between the pump's inlet and outlet.  The algorithm defines a fluid delivery protocol that is applied in controlling the operation of the pump to achieve a desired rate, volume, and timing of the fluid infusion. Fluid is delivered by the pump when a plunger (42) compresses an elastomeric membrane (29) overlying a fluid chamber (30). Due to the small volume of the chamber, an incremental change in the plunger position before the delivery stroke produces a significant change in the delivery pressure. At the beginning of a pump cycle, the microprocessor determines the differential pressure between the inlet and outlet of the pump, and adjusts the plunger position before the delivery stroke to compensate for the differential pressure. A  retraction of the plunger from the home position decreases the delivery pressure of the fluid, and an advancement of the plunger increases it. After the position of the plunger is adjusted to compensate for the differential pressure, the pump cycle proceeds.  Following the plunger stroke, the outlet pressure is used to determine the actual volume of fluid delivered. The duration of the plunger stroke in the next pump cycle is adjusted to compensate for any volume delivery error produced by the differential pressure compensation.
