Patent CA-2347072-A1 (CA)
Title: Multi-table based grant generator for improved granularity in an atm-pon
Inventor: MAESSEN J H J
IPC: H04L12/56
Filed: 2001-05-10
Abstract: A multi-table-based grant generator in accordance with the present invention solves the issue of bandwidth granularity, while maintaining the simplicity of a table approach. The present invention grant generator provides grants of fine granularity for regulation of upstream transmission. of cells in an ATM PON. Multiple grant tables having differing bandwidth granularities are linked together through a simple grant distribution mechanism. The grant tables and grant distribution mechanisms can be recursively linked to achieve a number of different granularities. The grant generator of the present invention is based on multiple grant tables with a combination of multiplexers, dividers, and address counters. The grant generator provides both larger and smaller bandwidths for data grants as well as PLOAM grants without large size grant tables. In one exemplary embodiment of the present invention, improved granularity is achieved, where a first grant table is used for one size of bandwidth grant, e.g., data grants, and the second grant table is used for another size of bandwidth grant, e.g., low bandwidth data grants as well as PLOAM grants. A simple clock divider couples to each of the grant tables through corresponding address counters. The clock divider provides a~ set number of bandwidth grants from each table over a complete cycle. The clock divider also selects an appropriate input port of a multiplexer through which the grants from each grant table are respectively transmitted. By having the ability to issue variable sized bandwidth grants, the granularity is significantly improved, thereby translating to a more efficient use of the bandwidth. More specifically, grants of a finer granularity can be~ issued without the need for an excessively large grant table usually thought to be necessary to produce fine granularities.

Title: Two-themes-in-one doll
Inventor: FRAZER-GREEN ANN
IPC: A63H3/12
Filed: 2001-12-17
Abstract: It is a three-dimensional rag-doll type of doll that has two themes-in-one.  The whole doll is one piece comprised of two upper half bodies (upside down in relation to each other) whereby each half is comprised of one head and upper torso with left and right arms attached, one dress skirt and one dress bodice. Each half of the doll portrays a different identity or theme, for example one half awake and the other half asleep. The doll is able to flip from one theme into another by the person holding the doll lifting up its skirt over its head and thus revealing the second head and theme. The dress, therefore, hides one head and creates the appearance of a single doll at any one time. It is a toy and its intention is that it be used by children in play or by enthusiasts for collectors' purposes.

Title: Fluorination
Inventor: VENTER PETRUS JOHANNES
IPC: C07B/
Filed: 2000-05-18
Abstract: A process for fluorinating a hydrocarbon substrate is by mixing it with an inert diluent and mixing the diluted substrate with a gaseous fluorinating reagent to form a foam reaction mixture. The fluorinating reagent reacts with the substrate in the form to foam product.  The foam is separated into a liquid component which contains product and a gas component. Product is withdrawn from the liquid component which is then returned to the diluting step. Fluorinating reagent is fed into the gas component which is then recirculated to the mixing step.  An installation for fluorinating a hydrocarbon substrate includes, in sequence as a circuit, a dilution stage, a mixing stage, a reaction stage and a separation stage. Liquid returning means feeds liquid from the separation stage to the dilution stage, and gas recirculation means feeds gas from the separation stage to the mixing stage.
