Patent CA-2307718-A1 (CA)
Inventor: MANTEGNA JOHN
IPC: G10L19/038
Filed: 1998-10-28
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.
Patent CA-2310862-A1 (CA)
Title: Bracket assembly with split clamp member
Inventor: PARDUHN A PHILIP
IPC: G09F7/18
Filed: 2000-06-02
Abstract: A bracket assembly to support a traffic control device or other object on a mast arm or other support. The bracket assembly generally includes male and female tubular members. The female tubular member is split longitudinally, and clamped around the male tubular member by means of bolts or the like. The two halves of the split female member are identically formed, which simplifies manufacturing as only one mold is required. Further, each of the female member halves is provided with attachment means for using either cable or steel band to mount the bracket to the mast arm. Each half of the female member has a notch or pawl to which the band/cable screw assembly is inserted. When the two identical halves are placed around the male tubular member, the paw is on opposite sides of the anchor plate. In this way, the tension on half is exerted in a direction opposite to the tension on the other half. Still further, because the female member is clamped around the male member, rather than the male member being inserted in female member telescopically, no separate parts are required to axially secure the connection. Instead, in the preferred embodiment, a shoulder integrally formed in the female member engages a flange integrally formed on the end of the male member. Thus, installation is simplified; there are no small set screws or snap rings to manipulate.
Patent CA-2310949-A1 (CA)
Title: Wideband optical packet ring network
Inventor: ANDERSON JON
IPC: H04B10/275
Filed: 2000-06-05
Abstract: A dual-ring, bi-directional optical fiber transmission system interconnects a series of add/drop nodes with a hub, such that multiple, widely spaced coarse wavelength division multiplexed (C-WDM) channels are established on each ring.     At each node, an optical add/drop module (OADM) includes broadband filters (BBF's), such as dielectric thin film filters, arranged to (a) extract, for the purposes of a receiver, or (b) insert, for the purposes of a transmitter, information in one or more of the channels. The signals in the one or more channels are coupled to the OADM's by a standard optical transceiver, which performs modulation and demodulation. Each filter passband can be populated with multiple dense wavelength division multiplexed (D-WDM) channels, so that the capacity of traffic that can be handled at each node can be easily upgraded. The transceiver is, in turn, coupled to packet framer, such as an IP packet over SONET framer, which supplies received packets to, and receives outgoing packets from, a conventional Layer routing engine. While in most instances, endpoints at each of the nodes communicate with other endpoints connected to the hub, if desired, endpoints at one or more nodes can communicate directly with endpoints on other nodes, using a direct or bypass connection through the hub. The bypass can be "permanent" or controlled via a switch, such as a micro-electro-mechanical switch (MEMS).
Patent CA-2311399-A1 (CA)
Title: Optical inter-ring protection having matched nodes
Inventor: PARE LOUIS-RENE
IPC: H04Q11/04
Filed: 2000-06-08
Abstract: The matched nodes provide protection for a failure in the connection between two bidirectional line switched rings. They use a secondary path in case of a primary path failure. The secondary path is set aside in either the working or protection bandwidth of the rings, thus wasting resources. The invention uses inter-ring protection mechanisms which do away with a specifically set aside secondary path between the primary and secondary nodes.
Patent CA-2313978-A1 (CA)
Title: Data link protocol for wireless systems
Inventor: KRISHNAMOORTHY RAJEEV
IPC: H04W28/04
Filed: 2000-07-13
Abstract: A two layered segmentation technique coupled with a two layer error detection technique is used to implement the wired to wireless network interface. A  wireless network divides network layer packets from a wired network into radio data link packets, and the information within the radio data link packets is divided into portions that can be placed into time slots. Error detection is performed on each of the time slots and also at the radio data link packet level to determine if there is an error within the radio data link packet. Errors detected in any radio data link packet only requires retransmission of the radio data link packet in which the error was detected, and, advantageously, do not require retransmission of the entire network layer packet as would have been required in a system that mapped directly from network layer packets to time slots. Further advantageously, the system is able to be employed by systems that utilize dynamic constellation mapping schemes which result in different time slots for the same user being mapped with different constellations, and so they have different bit to symbol ratios. This is because such changes in the constellation mapping scheme are handled at the time slot level, and are not seen at the radio data link packet level. The segmentation of the network layer packets into radio link packets is independent of the number and size of the time slots which will carry the radio link packets.

Title: Dram data storage and movement for network processors using dual dram storage
Inventor: CALVIGNAC JEAN LOUIS
IPC: G11C11/407
Filed: 2000-08-17
Abstract: The ability of network processors to move data to and from dynamic random access memory (DRAM) chips used in computer systems is enhanced in several respects. In one aspect of the invention, two double data rate DRAMS are used in parallel to double the bandwidth for increased throughput of data. The movement of data is further improved by setting 4 banks of full 'read' and 4 banks of full 'write' by the network processor for every repetition of the DRAM time clock. A scheme for randomized 'read' and 'write' access by the network processor is disclosed. This scheme is particularly applicable to networks such as Ethernet that utilize variable frame sizes.

Title: Adeno-associated virus and adenovirus chimeric recombinant viruses useful for the integration of foreign genetic information into the chromosomal dna of target cells
Inventor: VALERIO DOMENICO
IPC: C12N5/10
Filed: 1998-12-23
Abstract: The present invention provides chimeric viral vectors which have both the capacity to infect host cells efficiently and the capacity to integrate their genomic material into the host cell's genome. Therefore the invention provides such a chimeric viral vector which comprises a functional packaging signal derived from a first virus and an integration means derived from a second virus. Typically viruses capable of integrating their material into a host cell genome, preferably provided with additional genetic material introduced therein by recombinant means, do not have much room for insertion of such additional genetic material or are not very well capable of infecting every wanted host cell. Typically viruses that are very well capable of infecting many host cells either also do not have a high insertion capacity or do not integrate their genomic material provided with said additional genetic material into the host cell's genome. The present invention provides a solution to the problem of getting large inserts integrated into a host cell's genome at an efficient infection rate by combining the properties of efficiently infecting viruses with efficiently integrating viruses. A good working example of the present invention is provided in a combination of adenovirus and adeno associated virus.
