Patent CA-2457909-A1 (CA)
Title: Method and system for self-organizing reliable, multiple path data flow transmission of data on a network
Inventor: DAVIES CHRISTOPHER
IPC: H04L12/54
Filed: 2004-02-16
Abstract: A system and method for self organizing, reliable, multiple path data flow transmission of messages data on a network uses queues to transmit messages between end-user modules (EUMs) on nodes on the network. The EUMs include the end user applications with which queues are associated. A network communications manager (NCM) resident on every node manages all transmission of messages between nodes.      The NCM on a given node only has knowledge of nodes that are neighbor nodes to that given node, but has knowledge of all queues associated with all EUMs. Messages are divided into EUM messages, which are placed in queues by the NCM on each node, and system messages, which are not placed in queues but are used by the NCM to determine when and where, i.e. to which neighbor node, messages may be sent. The NCM on each node chooses a neighbor node as a target node for sending EUM messages for each queue, based on the best node latency and at capacity status of each neighbor node. These target nodes are used to provide potential routes to queues and multiple path data flow for queues that carry EUM data messages for user applications. These target nodes are constantly updated to provide the best paths on an adaptive basis and to ensure that all paths are valid, improving network reliability.      When choosing when to send data to a target node, each node uses tokens for flow control to ensure that target nodes do not become overloaded. The node also compares node latencies for multiple target nodes to ensure that the lowest node latency target node is chosen.      By using neighbor nodes as target nodes, node latency, and at capacity information for determining when and where to send data, there is no need to maintain any global knowledge of all paths in the network. Further, the constant updating of target nodes ensures that the network maintains optimal and valid paths for messages, thus ensuring efficiency and reliability.  Finally, the constant updating of target nodes ensures that reliability and efficiency are provided on an adaptive, self organizing basis.

Title: A method for managing multiple file states for replicated files
Inventor: RAYSON STEVEN JAMES
IPC: G06F1/00
Filed: 2004-02-17
Abstract: A server is implemented with a modified file open action, which, when a user performs the modified open, initially opens a file without locking the file. When a user indicates (either explicitly or implicitly) that the user is attempting to or intending to open the file, the file can then be locked for editing. In this way, the default action when a user requests a file is to open the file without denying other users access to the file. Then, when the user indicates that editing should occur, the lock for the file is obtained.

Title: Sawing direction positioning system for a jigsaw
Inventor: ZHANG ROSS
IPC: B23D59/00
Filed: 2004-06-10
Abstract: The present invention relates to a sawing direction positioning system far a jigsaw comprising a light-emitting unit for emitting a planar light beam, said light-emitting unit being connected with a power supply via a lead and positioned above said jigsaw so that said planar light beam emitted from the Light-emitting unit coincides exactly with the plane of a saw blade mounted on said jigsaw. During sawing, the projection line of the planar light beam always projects on the wood to be sawed and is not obstructed by the sawdust. The operator may have a good visual field and push the wood to be sawed along the curve line to ensure that the projection line always keeps tangential to the curve fine drawn on the wood and the saw blade always saws the wood along the projection line, thereby preventing the kerf from offsetting and reducing the rejected products.

Title: Apparatus and method for ion cyclotron resonance mass spectrometry
Inventor: O'CONNOR PETER B
IPC: H01J49/40
Filed: 2003-01-08
Abstract: An apparatus and method for performing ion mass spectrometry via Fourier transform ion cyclotron resonance utilizes a superconducting magnet with a bore and a vacuum chamber received in the magnet bore. The superconducting magnet and the vacuum chamber are enclosed in a cooling chamber and cooled together until the operating temperature of the magnet is reached. Because the temperature of the vacuum chamber is similar to the operating temperature of the superconducting magnet during operation, the wall of the vacuum chamber is sufficiently cold to function as a cryogenic vacuum pump to provide enhanced pumping of the volume in the vacuum chamber. The approach of cooling the vacuum chamber wall to provide cryogenic pumping can also be used when the magnet is of a non-superconducting type.

Title: Systeme laser haute puissance de faible cout, ultra compact
Inventor: UNGAR JEFFREY E
IPC: H01S5/00
Filed: 2003-04-21
Abstract: La présente invention concerne un système laser qui présente un réseau à impulsion modulée en fréquence et un combinateur optique couplé à une diode laser. La diode laser génère une impulsion laser en réponse à une impulsion électrique d'un circuit d'attaque. A cause de divers effets internes, la partie arrière de l'impulsion laser contient de la lumière présentant des longueurs d'ondes plus longues que la lumière à l'extrémité avant de l'impulsion. L'impulsion laser traverse le combinateur en direction du réseau à impulsion modulée en fréquence. Le réseau à impulsion modulée en fréquence présente un espacement qui diminue, d'une extrémité proximale à une extrémité distale du réseau. Les longueurs d'ondes plus longues de l'impulsion laser sont réfléchies par l'extrémité proximale du réseau. Les longueurs d'ondes plus courtes sont réfléchies à partir de l'extrémité distale du réseau et sont combinées avec les longueurs d'ondes plus longues au niveau du combinateur. Les longueurs d'onde plus courtes, à l'avant de l'impulsion, doivent parcourir une distance supérieure aux longueurs d'ondes plus longues. La distance supérieure ramène spatialement les longueurs d'ondes plus courtes en longueurs d'ondes plus longues de l'impulsion. On obtient ainsi une impulsion laser haute puissance, courte.

Abstract: An injection molding apparatus (10, 110) for molding an annular thermoplastic element, such as an annular closure element (E) with no more than a single weldline in the annular extent of the thermoplastic element.          The thermoplastic element is molded in an annular mold cavity (12, 112), and moldable thermoplastic material (M) is introduced into the mold cavity from a coaxially-aligned annular flow path (18, 118) that is defined between a sliding sleeve (24, 124) and an annular member (22, 122). The sliding sleeve surrounds and is slideable with respect to a fixed pin (26, 126) and is slideable between a first, or forward, position, where no thermoplastic material can flow into the mold cavity, and a second, or rearward, position, where thermoplastic material can flow into the mold cavity. Thermoplastic material is introduced into the annular flow path, at a location upstream of the second position of the sliding sleeve, in a single stream through a passage (28, 128) to limit the weldlines in the molded thermoplastic element to no more than one.

IPC: H04B7/185
Filed: 1997-12-04
Abstract: A satellite communications system provides a communications service to a mobile terminal (2) on which different communications applications (4a to 4d) may be run. Calls are set up between any of the applications (4a to 4d) via a satellite (12) to a network management centre (18) which provides different service adaptors (20a to 20d) which adapt the calls to different types of service provided over terrestrial networks (22), such as telephony, facsimile, internet or ATM services. The bandwidth allocated to each call over the satellite link may be varied during the call according to demand either from the relevant application (4) or from the network management centre (18). Multiple calls may be connected concurrently to or from different applications running on the mobile terminal. A maximum bandwidth is allocated to each call.  Efficient use is thereby made of the limited bandwidth available over the satellite (12), according to the instantaneous bandwidth requirements of different applications {4). For real-time calls requiring multiple slots per frame in a TDMA channel, the slots are mutually spaced apart to reduce delay.
