Abstract: A packet forwarding apparatus provided with a plurality of line interface units, comprises a routing processing unit, a flow detection unit and a packet forwarding unit. The routing processing unit refers to a routing table based on header information in a received packet to specify one of a plurality output lines to which the received packet is output. The flow detection unit refers to an entry table in which a plurality of entries with flow conditions and control information are registered to retrieve control information defined by the entry with a flow condition which coincides with that of the header information of the received packet. The packet forwarding unit transfers the received packet to one of the line interface units connected to the output line specified by the routing processing unit. An entry table is divided into a plurality of subtables corresponding to the values of flow attributes associated with the received packets. The flow detection unit retrieves the control information from one of said subtables specified by the value of the flow attribute corresponding to the received packet.

Patent CA-2307718-C (CA)

Abstract: A reduced-complexity real-time audio coder/decoder ("codec") using adaptive sparse vector quantization (ASVQ) classifies signal vectors into one of a plurality of different types. The codec provides low bit-rate compression for music and speech, while being applicable to higher bit-rate audio compression. It includes an in-path implementation of psychoacoustic spectral masking, and frequency-domain quantization using ASVQ and audio-compression algorithms. Critically-sampled subband filter banks maintain time-domain continuity across frame boundaries. In-path spectral masking usually results in sparse vectors. ASVQ is particularly effective for quantizing sparse signal vectors. In the preferred embodiment, ASVQ classifies signal vectors into six different types (504, 508, 512, 516, 520, and 522). The ASVQ technique applies to general-purpose data quantization as well as to quantization for audio compression. The invention also includes a "soft-clipping" algorithm in the decoder as a post-processing stage, which preserves the waveform shapes of the reconstructed time-domain audio signal in a frame- or block-oriented stateless manner while maintaining continuity across frame or block boundaries.

Abstract: L'invention concerne un procédé et un système permettant d'identifier dans une base de données une ou plusieurs saisies de données constituant les éléments les plus proches d'une interrogation. La base de données préétablit une première série de chaînes par sélection probabiliste de valeurs des bits respectifs dans chacune des chaînes de la première série, sur la base d'une probabilité qui dépend d'une première distance de Hamming. Compte tenu de la première série considérée, la base de données prédétermine les valeurs de trace de chaque saisie de données dans la base de données, respectivement, et enregistre les valeurs de trace prédéterminées comme saisies dans une table de traces. Pour chaque saisie de valeur de trace, la base de données identifie les saisies de données pour lesquelles les valeurs de trace sont en deçà d'une seconde distance de Hamming de la saisie de valeur de trace, et elle enregistre les adresses des saisies de données identifiées dans la saisie de valeur de trace. Lorsqu'elle reçoit une interrogation, la base de données identifie les saisies de données se trouvant en deçà de la première distance de Hamming de l'interrogation par le biais d'une identification, dans la table de traces, de la saisie de valeur de trace correspondant à la valeur de trace de l'interrogation. L'invention concerne également un procédé et un système permettant d'estimer la distance de Hamming entre deux chaînes dans un réseau.

Title: Radar for space-borne use
Inventor: CORDEY RALPH ANTONY
IPC: H01Q15/24
Filed: 2000-09-22
Granted: 2010-04-13
Abstract: Faraday Rotation causes rotation of the plane of polarisation of plane polarised radiation emitted by a radar e.g. a synthetic aperture radar and, if returns polarised in orthogonal planes are measured at the synthetic aperture radar in order to determine polarimetric characteristics of the ground, which could show up features of the ground such as crop patterns, the measurements made at the SAR are contaminated by the Faraday Rotation. In the invention, the transmitted plane polarised beam is pre-rotated in transmitter 9, the radar returns in receiver 13 are mathematically adjusted in signal formatting 14, 15 to compensate for just the pre-rotated angle, to produce data streams on downlink 16 uncontaminated by the Faraday Rotation. The Faraday Rotation may be estimated by external means 11, 12, or by performing correlation 10 of the orthogonally polarised radar returns to establish a minimum, while the pre-rotation angle and mathematical correction of the returns are being iteratively adjusted, at which Faraday Rotation is assumed to be compensated.

Abstract: A wireless receiver receiving multipath Walsh-code symbols determines which of fingers (402, 410) have locked on a signal. Measurements of the correlation energies between the received signal and all possible symbols are stored in energy storage units (404, 412). The actual signals are combined in combiner (408). A maximum determiner (416) determines the most likely combined symbol, and an index for this symbol is fed back to the energy storage units. Lock detectors (406, 414) use the measurement for this fed-back symbol to determine whether the finger has locked onto a path. This determination is used to decide whether the next signal detected by that finger should be applied to the combiner.

Abstract: A process is disclosed for the in situ conversion and recovery of heavy crude oils and natural bitumens from subsurface formations using either a continuous operation with one or more vertical injection boreholes and one or more vertical production boreholes in which multiple, uncased, horizontal boreholes may extend from the vertical boreholes, or a cyclic operation whereby both injection and production occur in the same vertical boreholes in which multiple, uncased, horizontal boreholes may extend from the vertical boreholes. A mixture of reducing gases, oxidizing gases, and steam are fed to downhole combustion devices located in the injection boreholes. Combustion of the reducing gas-oxidizing gas mixture is carried out to produce superheated steam and hot reducing gases for injection into the formation to convert and upgrade the heavy crude or bitumen into lighter hydrocarbons. Communication between the injection and production boreholes in the continuous operation and fluid mobility within the formation in the cyclic operation is induced by fracturing, multiple horizontal boreholes extending from vertical boreholes, or other related methods. In the continuous mode, the injected steam and reducing gases drive upgraded hydrocarbons and virgin hydrocarbons to the production boreholes for recovery. In the cyclic operation, wellhead pressure is reduced after a period of injection causing injected fluids, upgraded hydrocarbons, and virgin hydrocarbons in the vicinity of the boreholes to be produced. Injection and production are then repeated for additional cycles. In both operations, the hydrocarbons produced are collected at the surface for further processing.
