Patent CA-2118278-A1 (CA)
Inventor: GARLAND J DAVID
IPC: H04N7/173
Filed: 1994-10-17
Abstract: The provisioning of a multimedia application is enhanced by using a communications protocol which defines a number of different functions and which allows a multimedia application to be segmented into a plurality of logical blocks such that a user may enter a request characterizing one such function and, in response thereto, the system performs the function with respect to a particular one of the logical blocks. The underlying multimedia system is also enhanced by arranging it so that an application provider may interact with the system via a telecommunications network for the purpose of, for example, storing the application thereon andlor "debugging" the stored application.

Title: Closed loop liquid circuit pack cooling
Inventor: AZAR KAVEH
IPC: H01L23/473
Filed: 1995-10-13
Abstract: Improved heat dissipation is achieved by a microelectronic device comprising: a package body having at least one interior duct formed therein through which a cooling fluid may pass; one or more integrated circuit dies disposed within the package body in a manner allowing the one more integrated circuit dies to be exposed to the cooling fluid; and connectors for connecting the one or more integrated circuit dies to an electrical circuit external to the microelectronic device. In an illustrative example of the invention, the interior duct is coupled to an external cooling fluid supply and return via openings on the sides of the package body, to advantageously provide the package with the same profile as a conventional package. In another illustrative example of the invention, the duct is separated from the integrated circuit die by a thin partition disposed in the package body. The thin partition is adapted to prevent direct contact between the cooling fluid and circuit die while offering minimal thermal resistance thereby allowing a high degree of heat transfer to the cooling fluid.

Patent CA-2175448-A1 (CA)
Inventor: GIRARD YVES
IPC: B60D1/06
Filed: 1996-04-30
Abstract: Pour joindre une remorque à un véhicule à usage personnel ou professionnel, le cas échéant, on sait qu'il faut un coupleur fixé à l'avant de la remorque et une attache fixée à l'arrière du véhicule. Dans la présente invention, l'attache est pivotante et perforée. Quant au coupleur, il est lui-même perforé et relié à l'attache par une tige de sécurité en métal. En pivotant, l'attache fait corps avec le coupleur réduisant ainsi l'effet de friction qui engendre l'usure prématurée des deux pièces. Une tige de sécurité en métal a été ajoutée pour prévenir un éventuel décrochement de l'attache et du coupleur, incidents qui surviennent surtout sur terrains accidentés.
