Title: Method and apparatus for continuous cross-channel interleaving
Inventor: WADIN CRAIG P
IPC: H04B7/195
Filed: 2000-05-24
Abstract: A method of interleaving data for transmission is provided wherein first (106) and second (108) interleaving patterns for arranging data symbols in a source data stream (110) into first (106) and second (108) transmitted data streams are selected. Each of said data symbols has at least one bit. The first (106) and second (108) transmitted data streams are transmitted substantially simultaneously on separate transmission channels (102 and 104) to at least one receiver. The first (106) and second (108) patterns are used to transmit the data symbols in the source data stream (110) in a different order on the respective transmission channels (106 and 108) to maximize recovery of the source data stream (110) when the transmission channels (106 and 108) are blocked. The selected interleaving patterns can involve reordering the data symbols throughout the first (106) and second (108) transmitted data streams (106 and 108) using different reordering criteria. The reordering criteria can vary on a frame-by-frame basis if the source data stream (110) is time division multiplexed. Complementary data can be sent on respective transmission channels (102 and 104).

Abstract: Les éléments de texte en clair et les éléments de matrice de masquage sont convertis en chiffres d'une autre base de numération (étape 2). Le chiffres résultants sont combinés modulo la nouvelle base de numération, et pour reconvertir le résultat en éléments, on utilise la base de numération originale qui donne les éléments en texte chiffré (étape 4). Pour rétablir le texte en clair, on prend les éléments du texte chiffré et les éléments de matrice de masquage, et on les reconvertit en chiffres dans la même base de numération que ce que l'on a utilisé pour le cryptage. On utilise alors une combinaison arithmétique inverse de ces chiffres, modulo la nouvelle base de numération, la reconversion du résultat de cette combinaison en éléments selon la base de numération originale donne alors les éléments du texte en clair original.

Title: Synchronization of ofdm signals with improved windowing
Inventor: YONGE LAWRENCE W III
IPC: H04L27/26
Filed: 2000-04-25
Abstract: A mechanism (80) for determining phases of a symbol for phase correlation is provided. The mechanism (80) performs a symmetric apodizing window function on a symbol sample of a symbol having a symbol period of T and a time-offset symbol sample offset from the symbol sample by T/2 to produce first windowed values for the symbol sample and second windowed values for the time-offset symbol sample. The mechanism (80) applies a time shift to re-align the time-offset symbol sample with the symbol sample and sums the second windowed values and the corresponding first windowed values. The summed values are then converted to phases. The symmetric apodizing window function is an apodizing window function having the property W j +  W(FFTSize/2+j)= constant, where FFTSize is the size of the FFT sample. The symmetric apodizing window function, such as a Hanning window, may be performed in the time of frequency domain.

Patent CA-2376032-A1 (CA)
Inventor: LEE CHENG YIN
IPC: H04L47/80
Filed: 2000-06-02
Abstract: A method to engineer paths for multicast traffic in an IP network, by directing the control messages to setup multicast trees on engineered paths,  is disclosed. The multicast traffic engineering process is separated from th e multicast route setup and the resources and the paths for multicast data delivery can be aggregated and independently allocated. Resources are allocated on the same trip when paths are selected and setup, and this prevents data from being forwarded on branches where resources have not been  yet allocated. The trafic can be statistically multiplexed enabling the network operators to have control over the topology of the multicast trees a nd to provide differentiated services in a scalable manner.

Patent CA-2389207-A1 (CA)
Inventor: CARTER STEPHEN A
IPC: F17C13/04
Filed: 2000-08-24
Abstract: This invention provides a system to manage high-pressure cylinders. A gas-powered vehicle would preferably have one master (20) and any number of slave cylinders (21). The master valve (40) wouldpreferably include pressure and temperature sensors, a high-pressure fuel portal mechanism and a pressure regulator. The sensors communicate the cylinder conditions to the filling station during refueling, so that a maximum fill could be achieved. The sensors would also allow integral electronics to accumulate fatigue information and to permanently take the cylinder out of service once the safety limit point was reached, by permanently disabling the internal high-pressure fuel portal device. The regulator would preferably receive gas from all the cylinders and reduce the output to the desired low pressure. The invention includes a means to control fuel temperature, further reducing the heat extracted from the engine's coolant.

Abstract: La présente invention concerne une prothèse tubulaire de valvule cardiaque semi-lunaire ou atrioventriculaire que l'on forme en coupant des valves flexibles selon un modèle. On construit la valvule en alignant les bords latéraux de valves adjacentes de façon que les faces internes des valves sont en contact les unes avec les autres, et l'on suture ensuite les valves ensemble par points successifs le long d'une ligne de pliure adjacente aux bords latéraux. Les points sont placés successivement depuis une extrémité proximale d'entrée de flux de chaque valve en direction d'une extrémité distale de sortie de flux. Au cours de l'opération, lorsque les valves s'ouvrent et se ferment, elles se plient le long de la ligne de pliure. Des pattes distales s'étendent au-delà de l'extrémité distale de chaque valve. Les points successifs se terminent à proximité de la partie patte distale de façon qu'aucun point fermé n'est placé le long de la partie distale de la ligne de pliure. Les parties pattes de valves adjacentes sont repliées les unes sur les autres et cousues ensemble pour former des pattes de fixation commissurales. Les pattes commissurales constituent des points de fixation commissuraux destinés à accueillir les sutures et analogues afin de fixer la patte à la paroi d'un vaisseau dans le cas d'une valvule semi-lunaire, et aux muscles papillaires et/ou aux cordages tendineux dans le cas d'une valvule atrioventriculaire.

Title: Apparatus and method for making stackable snack food chips
Inventor: CHEN NELSON SHIH-HSUN
IPC: A23G3/34
Filed: 2001-02-07
Abstract: An apparatus and method for making uniformly shaped snack food chips which can be stacked for packaging, e.g., in a cylindrical canister or a canister which conforms to the contour or perimeter of the snack food chips. The apparatus features two-part mold cavities in which chip preforms are restrained and transported through hot oil to be cooked. Preferably, the mold cavities are defined between a pair of rotating belts, one lower belt and one upper belt, which together "encase" or "sandwich" and thereby restrain the chips. According to the method, a continuous sheet of dough is toasted and then proofed before being cut into individual chip preforms. The preforms are then placed into the mold cavities and transported through hot oil to be cooked. Vacuum transfer rollers are used to facilitate placement of the chip preforms into the mold cavities and extraction of the cooked chips from the mold cavities.

Title: Network routing and congestion control
Inventor: SHIPMAN ROBERT ANDREW
IPC: H04L45/24
Filed: 2001-03-29
Abstract: In a communications network of nodes (110) connected by links (115), routing of traffic is done according to routing tables available to the nodes (110). The routing table for each node shows fields for destination nodes (210) and for next hop nodes (205) towards those destination nodes, and traffic is routed at each node according to values entered in those fields. The nodes modify the values in the fields according to messages received from neighbouring nodes. This controls traffic flow in that values are raised on receipt of messages from neighbouring nodes. If messages are received less frequently from a node, for instance because of congestion in the network or failure of a node, the values for that node will be relatively depressed and the network will tend to route traffic away from the node.
