Patent CA-2405839-A1 (CA)
Inventor: STAMM BEAT
IPC: G06T11/00
Filed: 2001-04-09
Abstract: La présente invention concerne le positionnement automatique de caractéristiques typographiques tels que des tiges verticales ou des segments horizontaux d'un caractère (205) au niveau des limites à fort contraste d'un sous-composant pixel dans le cadre d'un processus de restitution qui utilise des sous-composants pixel commandés séparément (202, 203, 204) de pixels pour représenter différentes parties d'un caractère (205). Pour identifier les caractéristiques typographiques du caractère (205) qui doivent être alignées sur des limites à fort contraste de sous-composant pixel, on analyse la topologie du caractère pendant l'exécution. Sur des dispositifs d'affichage avec bandes verticales de sous-composants pixel de même couleur (202, 203, 204), il est apparu que la lisibilité du caractère augmentait lorsque les bords gauches des tiges (206) étaient alignés sur les limites à fort contraste (208) entre sous-composants pixel. Il est possible de réduire le temps de traitement et les ressources requises en procédant à une analyse topologique partielle, et non complète, du caractère. Certains fichiers de polices de caractères renferment par exemple des structures de données qui permettent de définir des points de contrôle clés associés avec tel caractère et qui indiquent l'emplacement des tiges et autres caractéristiques typographiques ainsi que la relation entre des caractéristiques typographiques différentes.
Patent CA-2406189-A1 (CA)
Title: High pressure rotating blowout preventer assembly
Inventor: BAILEY THOMAS
IPC: E21B33/08
Filed: 2001-04-12
Abstract: The invention provides a reduced downtime maintenance apparatus and method for replacing and/or repairing a subassembly in sealing equipment. It allows the removal of rotating portions (136, 138) of a rotary drilling head (114) without removal of non-rotating portions (132, 134). The reduction in size allows an efficient repair and/or replacement of a principal wear component such as packers. The packer (138) in a rotary drilling head can be removed independent of bearings and other portions of the rotary drilling head.  Because of the relatively small size and light weight, the packer can be removed without having to use a crane to lift a rotary BOP and without disassembling portions of the drilling platform. The packer can be removed with the drill pipe without additional equipment. The packer can be removed remotely without necessitating manual disengagement needed below the platform.  The invention provides a fluid actuated system to maintain a pre-load system on the bearing.

Inventor: PACHAL CYNTHIA G
IPC: A63B29/02
Filed: 2003-10-22
Abstract: An improved battery-powered device and system for avalanche transceiver rescue. The device comprises a transmitter, a receiver, microcontroller firmware system, graphic display, audio speaker and input switches residing in a single portable housing with a flip lid. When the Flip lid is closed, the system transmits a radio frequency signal at a predetermined interval. When the flip lid is opened, the system deactivates the transmitter and activates the receiver. The receiver comprises three mutually orthogonal tuned-coil antennas. The system digitally processes the received signal strength and polarity of the signal from one or more of the antennas to guide a user to a transmitting beacon. The antennas are spatially isolated permitting the use of higher-sensitivity antennas. The system digitally controls the sensitivity of each antenna enabling scans for signals based on a specified proximity range to the exclusion of other proximity ranges. The system also displays an indication when a degraded signal is received as a result of signal collision from multiple beacons.

Title: Fuel battery device and method for controlling fuel battery
Inventor: TAHARA MASAHIKO
IPC: H01M8/06
Filed: 2003-03-20
Abstract: The present invention relates to a fuel cell having an electricity generator which has an oxygen electrode, a fuel electrode, and a solid polymer type electrolyte membrane disposed between the oxygen electrode and the fuel electrode, and a method for controlling the fuel cell. The fuel cell has a problem in that the electrolyte membrane is dried to lower the ion-exchange characteristics when lowering the load current or increasing the air feed rate during the operation or when allowing the fuel cell to stand for a long time, so that the output of the fuel cell is considerably lowered. In the present invention, a load control portion for permitting a load on the fuel cell to vary depending on the output state of the fuel cell or an air feeding control portion is proved in the fuel cell and controlled to increase the load current or suppress the air feeding when the output characteristics are lowered or the internal resistance value is increased, thus solving the above problem.
Patent CA-2447866-A1 (CA)
Inventor: PAUL NICOLAS
IPC: F16K27/06
Filed: 2003-10-31
Abstract: A rotary plug valve has a plug portion which is rotatably fitted within a valve body. This plug portion of the valve is joined by a stem or shaft portion which extends out of the valve body to interact with an actuator and transmit torque to the plug portion. Pressure needs to be applied to the plug portion to insure a proper closure.  The invention relates to a mechanism to provide such pressure adjustment that uses only one screw that is positioned on the front of the valve cover for easy access.  The force generated by the screw is transposed into a vertical force by a cam. The multiple faces of the cam are used to transmit the force vertically and will maintain the mechanism in a straight position.
