Patent CA-2227931-A1 (CA)
Title: Modular electrical system
Inventor: MAY LINDY LAWRENCE
IPC: H02G3/08
Filed: 1996-08-22
Abstract: An electrical system including modular components which quickly assemble to create common lighting and general utility electrical circuits. All wiring is completed in the electrical box prior to installing the electrical devices such as switches (2) and receptacles (4), thereby eliminating the need for extra length wires in the electrical boxes and the cumbersome wiring practices associated with conventional residential electrical circuits. The electrical devices plug into the prewired electrical box, thereby providing quick and easy removal and replacement of the device in the event of failure. The common residential ligthing and general utility circuits are automatically configured by simply selecting the proper electrical components. A dedicated earth ground is automatically carried to each electrical component with no effort on the part of the installer, thereby providing safer electrical circuits. The electrical system provides multi-conductor cables (17-19) which have cable sheathes extruded to a specific exterior profile to insure proper connection with the electrical boxes thereby assuring proper configuration of the electrical circuits. The electrical system also eliminates the need for wire nuts.

Title: Method and system for simultaneous variable-width bus access in a multiprocessor system
Inventor: KAHLE JAMES A
IPC: G06F13/364
Filed: 1998-08-14
Abstract: A method and system for enhanced bus access in a multiprocessor system having multiprocessors coupled to a system memory via a common wide bus. The common wide bus is subdivided into multiple sub-buses which may be accessed individually or in groups by a selected processor, or individual sub-buses may be accessed by multiple processors simultaneously. In response to one or more pending transactions, each processor outputs a request to bus arbitration logic for a maximum-permitted number of sub-buses. If the number of sub-buses granted to a particular processor equals the number of pending transactions at that processor, all pending transactions are performed in parallel on separate sub-buses. If the number of sub-buses granted is less than the number of pending transactions, pending transactions are performed in a priority order. Finally, if the number of granted sub-buses is greater than the number of pending transactions, selected transactions are performed over multiple sub-buses in parallel, greatly enhancing the speed of those transactions.

Title: Cathode inerte pour la reduction selective d'oxygene et procede permettant de la produire
Inventor: ALONSO-VANTE NICOLAS
IPC: H01M8/1009
Filed: 1997-10-16
Abstract: Des cathodes inertes permettant la réduction d'oxygène, recouvertes d'une fine couche superficielle à action catalytique, conviennent à des piles à combustible. En présence de méthanol comme combustible, ce revêtement doit en outre présenter des propriétés sélectives que l'utilisation de matériaux en amas semi-conducteurs issus de chalcogénure de métal de transition, toutefois sous forme de poudre ou de fine couche, ne suffit pas à obtenir. La cathode inerte mise au point selon l'invention permet de parvenir aux propriétés catalytiques et sélectives voulues. Son revêtement superficiel mince comprend des amas du type susmentionné, répartis de manière homogène, comme une dispersion colloïdale, et sa production n'implique qu'une quantité minimale de matériau de l'ordre du nanogramme, pour un degré de couverture particulièrement faible avec un coefficient d'efficacité hautement sélectif et catalytique. Le revêtement s'obtient par immersion dans un colloïde qui contient le mélange en amas conjointement avec un stabilisant dans un solvant. Après application du colloïde, le solvant et le stabilisant sont éliminés par traitements thermiques.
