Title: Frame-based audio coding with additional filterbank to suppress aliasing artifacts at frame boundaries
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/022
Filed: 1998-10-01
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Patent CA-2317887-A1 (CA)
Inventor: WRIGHT DAVID A
IPC: H04B7/15
Filed: 2000-09-08
Abstract: Coordination of processing satellite uplink transmission and downlink transmission is achieved by an uplink encoder (418) and uplink modulator (420) which incorporate an adjustable IF amplifier (417) at a ground terminal (400).      Information about data traffic transmission errors detected in a satellite (100) is formed into ATM traffic report cells by a cell former (157). The traffic report cells are sent on the downlink to the ground terminal. The traffic report cells are used to adjust the power level of the IF amplifier for the particular channel and slot for which errors were detected.      Satellite 100 also detects the time of arrival of a synchronization burst signal at the satellite and estimates the received energy in the burst signal. Another cell former (144) forms ATM synchronization report cells, including information about the arrival time and energy, which are sent on the downlink to the ground terminal. The synchronization report cells are used to adjust the power of the IF amplifier for all channels and to adjust the time at which frames are transmitted on the uplink.
Patent CA-2320268-A1 (CA)
Inventor: SKUDUTIS TOMMY J
IPC: B21D26/02
Filed: 1999-02-08
Abstract: The present invention relates to a method for making a vehicle frame member having a shock absorbing mounting portion constructed and arranged to be mounted to a structural component within a motor vehicle. The method comprises hydroforming a tubular blank within a hydroforming die by supplying pressurized fluid to the hollow interior of the blank. A drawforming member is moved inwardly with respect to the cavity of the hydroforming die while the fluid is pressurized so that the drawforming member deforms a portion of the tubular wall inwardly to form a recessed portion having an annular side wall portion and a bottom wall portion. The formed tubular blank is then removed from the hydroforming die and a mounting structure (38) is disposed inside the recessed portion and the blank and mounting structure (38) are then disposed within an injection molding die. Molten shock absorbing material (14) is injected into the recessed portion so that the molten material (14) surrounds the mounting structure. The molten shock absorbing material is thereafter solidified. Preferably, a pair of such recessed portions are formed. The present invention also relates to a vehicle frame member to be joined to a structural component in shock absorbing relation.

Title: Preparation of recombinant adenovirus carrying a rep gene of adeno-associated virus
Inventor: COLLOCA STEFANO
IPC: C12N15/861
Filed: 1999-04-08
Abstract: Adenoviral particles are produced by incubating cells containing a helper adenovirus vector and a helper-dependent adenoviral vector including an AdenoAssociated Virus (AAV) rep gene, such as rep78. Cells are provided containing a helper adenovirus vector. A helper-dependent adenoviral vector including an AAV rep gene is introduced into the cells, for instance by infection with infective viral particles. The cells are incubated to produce adenoviral particles containing nucleic acid including the AAV rep gene. Advantageously, cells containing helper adenovirus vector are pre-incubated for 0.5-12 hours, preferably about 4 hours, to allow expression of viral proteins required for adenoviral genome replication before introducing the helper-dependent adenovirus vector including an AAV rep gene.

Title: Magnetically suspended flywheel system
Inventor: SUNATORI GO SIMON
IPC: H02N15/00
Filed: 2000-11-10
Abstract: .cndot. A magnetically suspended flywheel system comprises a housing, a stator assembly, and a rotor assembly. The stator assembly comprises a ring-shaped stator magnet having a substantially triangular cross section. The rotor assembly comprises a vertical shaft, a cone-shaped rotor magnet having a substantially triangular cross section, and a flywheel. The ring-shaped stator magnet has the same sense of magnetisation as the cone-shaped rotor magnet. The ring-shaped stator magnet forms inverse heart-shaped magnetic flux lines, and the cone-shaped rotor magnet forms heart-shaped magnetic flux lines. An upward magnetic repulsion force between the inverse heart-shaped magnetic flux lines of the ring-shaped stator magnet and the heart-shaped magnetic flux lines of the cone-shaped rotor magnet equals a downward gravitational force by the rotor assembly in order to passively suspend the rotor assembly so that the rotor assembly is capable of rotating around the central axis of rotation. This invention relates to flywheel systems, and the principal use of the invention is for kinetic energy storage systems.

Title: A system for delivering pressurized lubricant fluids to an interior of a rotating hollow shaft
Inventor: BROUILLET SYLVAIN
IPC: F01D25/18
Filed: 1999-06-03
Abstract: A system for delivering a pressurized lubricant fluid from a stationary source to an interior of a drive shaft of a gas turbine engine which rotates at high speed and operates at high temperatures is described.  The pressurized lubricant fluid is delivered to a radial passage defined between a pair of axially spaced-apart seals (24) that surround the shaft (12). To ensure reliable operation under the high speed and high temperature conditions, the seals are constructed so that a film of the lubricant fluid is formed between the rotating shaft and the seals. The seals float on the film and wear is reduced. In order to minimize variations in th space between the seals and the shaft caused by changes in operating temperatures, each seal is surrounded by a control ring (56) of material having a coefficient of expansion similar to the material of the shaft. The advantage is reliable delivery of lubricant to a shaft; rotating at high speed in a high temperature environment.

Abstract: Working memory in an SQL database system is organized in workspaces. Agent workspaces are defined into which working copies of SQL executable logic information are loaded. Application workspaces are also defined for the loading of working copies of SQL executable logic information. Reference copies of the SQL information are available in a global SQL cache. An application SQL context data structure is as an entry point to access working copies of SQL information in the agent or application workspaces. An application workspace is associated with an application and is maintained until the last application in the set is not active. An agent workspace is associated with an agent in the database system and is maintained until the agent is no longer active.
