Abstract: A method and apparatus to control a client (110) in a communications network (300) accessed by the client (110) through a service provider (210) independent of a client controller (400), such as an Internet service provider. When the client (110) starts the session, a start session message containing the user identity information is sent from the client (110) to the client controller (400) using the network (300) in accordance with a client control protocol. The client controller (400) can then determine whether the client (110) is authorized to use the network (300) based on the user identity information and, for example, a user database (410). If the client (110) is authorized, a session authorization message is sent to the client (110) authorizing the client (110) to use the network (300) for a predetermined period of time. When the client (110) stops accessing the network (300), the client (110) informs the client controller (400) by sending an end session message. If the client (110) wants to access the network beyond the predetermined period of time, the client (110) sends a continue session message to the client controller (400). If no end session or continue session message is received, the client controller (400) assumes that the client (110) is no longer accessing the network (300) at the end of the predetermined period of time. Other control messages, such as display and download commands, can also be sent from the client controller (400) to the client (110) using the client control protocol.

Title: Hydraulically-actuated fuel injector and cartridge
Inventor: POPP ROGER C
IPC: F02M21/02
Filed: 2001-01-04
Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg.300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions.  The fuel injector is powered by hydraulic signals from an electrohydraulic valve.  The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. The cartridge comprises an activator body and a valve body secured together, and the valve body has a gas valve slidable therein. The stroke of the valve is adjustable by controlling the size of shims in the valve body assembly, thereby providing a universal valve cartridge that can be easily adapted to differing fueling requirements for models and sizes of engines. The valve body includes a spring chamber between upper and lower valve guides. The valve body also includes cross-holes to allow cool gaseous fuel to successively pulsate into and out of the spring chamber and thereby cool the exposed portion of the valve between guides, preventing heating of the dynamic gas seal located in the upper guide. An unsealed small clearance between the actuating piston and its bore in the actuator body allows controlled leakage of oil. The leakage of oil lubricates metal to metal contact between the upper guide and the valve and lubricates the dynamic gas seal. Gaseous fuel leakage into the leaked oil is tolerated and any combined oil/gaseous fuel is removed to an external location for separation. Spring washers are used to urge the valve assembly insert against a metal O-ring supported by the outer cartridge body.

Title: Method for avoiding interference in a digital communication system
Inventor: HORVAT DION
IPC: H04W24/00
Filed: 2001-05-07
Abstract: A technique for time domain avoidance of communications link interference sources characterized by intermittent, periodic short bursts of energy. A  transmitting source can be assigned two time slots within a time domain multiple access data frame over which each data packet can be transmitted. The time slots are separated by a duration greater than that of an interference burst, such that an interference burst does not affect both time slots in any given frame. Therefore, the data packet can be received on at least one of the two assigned time slots. Transmitter power consumption can be reduced by calculating the timing of the periodic interference bursts, and only transmitting a data packet on one of the two assigned time slots that will not coincide with an interference burst in each frame. Communications link capacity can be improved during the presence of interference by synchronizing the data frame to the timing of the interference bursts. The bursts then occupy fixed time slots in each data frame, enabling standard single time slot transmissions for the remaining communications channels in the data frame.

Abstract: L'invention concerne des systèmes et des procédés permettant de fixer de manière amovible un appareil de positionnement dentaire (105) aux éléments dentaires (103) d'un patient au cours d'un traitement orthodontique. Ces appareils de positionnement dentaire amovibles (105) sont souvent préférés aux arcs conventionnels pour des raisons de confort, d'aspect et de facilité d'emploi. Les appareils de l'invention (105) fonctionnent par application d'une force sur des surfaces spécifiques des dents ou des éléments de dents (103) permettant un déplacement direct. Néanmoins, le type de déplacement et l'intensité de la force appliquée dépendent généralement des caractéristiques de surface et des positions des éléments dentaires (103). Dans bien des cas, ces aspects ne conviennent pas pour permettre un ancrage suffisant ou l'application d'une force très élevée sur les dents (103) à repositionner. On peut limiter ces restrictions en utilisant un ou plusieurs dispositifs de fixation (100) que l'on peut positionner sur les dents ou les éléments dentaires (103) afin d'obtenir des caractéristiques physiques appropriées. Une conception et un positionnement spécifiques de ces appareils de fixation (100) permettraient d'obtenir une force de repositionnement, une capacité d'ancrage et une contention de l'appareil inégalées et/ou plus efficaces.
