Title: A system for automatic generation of selective partial renderings of complex scenes
Inventor: KRATTLI JEAN-MARC
IPC: G06T15/00
Filed: 1999-03-30
Abstract: A computer-based system automates the production of so-called pass--images (or just "passes") from data defining 3-D scenes. For example, a beauty pass of a selected object the normal surface appearance without any background or other objects. A shadow pass shows only selected shadows and a highlight pass, only selected highlights. The passes allow pixel-processing to be done efficiently.  The processed passes can then be combined ("composited") to form the finished image. In the past, these passes were produced by editing a copy of the 3-D  scene for each pass and rendering the edited copy. The invention automates the production of passes by filtering the 3-D scene through pre-specified pass definitions that override properties of the 3-D scenes. The results of filtering are rendered (rendering largely comprises the process of ray-tracing) to form the passes. The system stores numerous pass definitions. Each time the 3-D scene is edited, the passes can be produced automatically from the pass definitions.  This automation of pass production also allows the passes to be used in the authoring environment by allowing a pass preview of the 3-D scene rendering. The automation of pass-production provides a tool that goes beyond merely reducing the labor involved in creating passes, it provides the author the option of invoking a new perspective, a different kind of immediate feedback, right in the authoring environment. This feedback enhances the author's ability to focus on specific features of a scene as the author edits the 3-D scene itself.

Patent CA-2271533-A1 (CA)
Title: Distributed instruction completion logic
Inventor: NGUYEN DUNG QUOC
IPC: G06F9/38
Filed: 1999-05-12
Abstract: Each execution unit within a superscalar processor has an associated completion table that contains a copy of the status of all instructions dispatched but not completed. A central completion table maintains the status of every dispatched instruction as reported by the dispatch unit and the individual execution units. Execution units send finish signals to the completion table responsible for retiring a particular type of instruction. The central completion table retires instructions that may cause an interrupt and instructions whose results may target the same register. The execution units' associated completion tables retire the balance of the instructions and the execution units send instruction status to the central completion table and to each execution unit.  This reduces the number of instructions that are retired by the central completion table,increasing the number of instructions retired per clock cycle.
Patent CA-2274376-A1 (CA)
Inventor: LEVKO FRED
IPC: H01H85/143
Filed: 1990-04-24
Abstract: The high speed fuse employs stamped end bell and terminals rather than forged or machined parts. A slot for the terminal is punched through the end bell. The terminal is inserted into the slot in the end bell and staked in position. This insures a strong tight fit without requiring welding or soldering. One end of each terminal has coined ridges to facilitate automatic welding of the fuse link to the terminals. Round balls are used to seal the fill holes for the arc quenching material. Metal pins secure the end bells within the fuse housing but are not electrically connected to the terminals because of the insulative end bells.
Patent CA-2275617-A1 (CA)
Title: Hybrid generator apparatus
Inventor: DA PONTE MANUEL DOS SANTOS
IPC: H02P/
Filed: 1997-12-19
Abstract: A hybrid generator set comprises an engine/generator or another controllable electrical source (10) which provides a variable voltage electrical output, this output is rectified and fed to a DC to DC converter (12), the output (VDC) of which is monitored by a control circuit (16). This output serves as an intermediate DC output, which typically is used to power an inverter (14) to generate an AC output which supplies an external load. The use of the DC to DC converter isolates the intermediate DC output from the generator output, and allows the generator set to operate efficiently over a wide engine/generator speed range, according to load demand.

Title: Method for updating secret shared data in a wireless communication system
Inventor: PATEL SARVAR
IPC: G09C1/00
Filed: 1999-07-20
Abstract: In the method for updating secret shared data (SSD) in a wireless communication system, a first party outputs a first random number as a first challenge wherein the first party is one of a network and a mobile. A second party generates a second random number in response to the first challenge. The second party is the mobile if the first party is the network, and the second party is the network if the first party is the mobile. The second party generates a first challenge response by performing a keyed cryptographic function (KCF) on the first challenge and the second random number using a secondary key, which is not the SSD and is derived from a root key. The second party then transfers the second random number, as a second challenge, and the first challenge response to the first party. The first party verifies the second party based on the first and second challenges and the first challenge response, generates a second challenge response by performing the KCF on the second challenge using the secondary key, and transfers the second challenge response to the second party. The second party, verifies the first party based on the second challenge and the second challenge response. Both parties respectively establish the SSD based on the first and second challenges.

Filed: 2000-03-02
Abstract: A collapsible flood barrier which may be readily deployed adjacent a flooding riverbank, and then inflated to form a temporary dike which is formed as a longitudinally elongated triangular tube closed at each of its ends. One or more drain and/or fill holes are formed in the tube to permit water to be pumped into and drained from the tube interior to inflate and deflate the flood barrier. One or more internal reinforcing members are located along the interior of the barrier. The reinforcing members are joined along each edge opposing portions of the barrier walls such that when fully filled, the barrier is characterized by a plurality of longitudinally extending outwardly convex arch-shaped portions. In use, flood barriers are oriented end-to-end in an outstretched position so as to extend longitudinally parallel to the bank of a flooding river. Water is then pumped from the river through the tube inlets to inflate the barrier. When fully filled, the volume of water which is pumped into the flood barrier provides the barrier with sufficient structural rigidity and weight as to prevent the flood waters from seeping underneath the barrier.

Title: Synchronous rectifying flyback converter with variable input and output voltages
Inventor: GRUWE ALAIN
IPC: H02M7/21
Filed: 2000-03-06
Abstract: A synchronous rectifying converter for variable input/output voltages and adapted to operate at both low voltages and large input/output voltage ranges. The converter includes a transformer with a main secondary winding (MSW) coupled to the output via a controlled electronic switch (CES) and a control secondary winding (CSW) for controlling the switch. The control secondary winding is connected to the junction point of the series connection of a diode (DD) and a capacitor (CP2) coupled across the main secondary winding. If the two secondary windings (MSW, CSW) have a same number of turns, the 'off' control voltage of the switch is zero, independently of the input voltage and the output voltage of the converter, whilst the 'on' control voltage is practically not influenced by the output voltage.
