Patent CA-2333913-A1 (CA)
Title: System for storing, mixing and administering a drug
Inventor: FELICELLI ROBERT
IPC: A61J1/00
Filed: 1999-06-04
Abstract: A container for holding a concentrated drug for a mixing system includes a barrel with a cover structure including a delivery passage at a first end and a closing structure at an opposite, second end. A female Luer lock fitting defines the delivery passage at the first end. The closing structure and the female Luer lock fitting can each be formed integrally with the barrel, or the closing structure can be a slidable stopper. The closing structure may also include a holder. The holder is constructed to move between two positions. In the first position, the holder is in an elevated position on the second end of the barrel. The barrel can vent vapor around the cover piece. In the second position, the holder is depressed onto the barrel and it cannot vent vapor. The cover structure may include a snap-on cover piece to fit over the first end. The cover piece includes the female Luer lock fitting. The cover piece functions similar to the holder. The container can be used in a mixing system which includes a diluent syringe with a barrel having a discharge passage at a first end, and a piston slidably and sealingly disposed in the diluent syringe barrel to define a diluent chamber adjacent the discharge passage. The syringe includes a male Luer lock fitting at its first end for releasably connecting to the female Luer lock fitting of the container. Diluent can be passed from the syringe into the container to mix with the concentrated drug and the resultant mixture can then be drawn from the container for administering to a patient.

Abstract: Le système de partage des ressources selon la présente invention ajuste dynamiquement les priorités, en vertu de quoi les demandes des applications dans des classes de demande différentes (ou classes de service) pour une ressource partagée sont traitées. La priorité dynamique d'une classe de demande est basée en partie sur l'affectation moyenne des ressources aux demandes dans cette classe de demande, et en partie sur les paramètres pour les affectations minimales et maximales pour cette classe de demande. L'affectation moyenne des ressources est la partie de temps pendant laquelle la ressource partagée a été attribuée aux demandes de cette classe par rapport à d'autres classes. L'ajustement dynamique des priorités utilise des « priorités variables » en vertu de quoi les priorités « varient » selon l'affectation moyenne des ressources; la priorité impose une contrainte au moment où les demandes d'une classe de ressource peuvent être satisfaites, à savoir : quand il n'y a pas d'autres demandes provenant de classes de demande de priorité supérieure en attente pour la ressource.

Title: Ski guide pressure intensifier plate (snow-speed)
Inventor: BUNTER ROLAND
IPC: A63C9/00
Filed: 2000-02-23
Abstract: By way of a ski binding assembly plate which can be fixed or can be adjusted in terms of its forward inclination and height the pressure on the front guide part of the ski is increased. By way of the fact that the ski binding assembly plate is fastened on the ski by way of a two-point support and arrest system, the ski obtains a free bending moment, by which means the ski is dynamic and runs very smoothly. A wedge function and a force transmission system prevent the ski from being propelled back by the counter pressure in the region of the ski binding. By way of a damping system vibrations and knocks are absorbed. The plate may be equipped with any brand of ski binding. It fits each type or brand of ski. The individual adjusting possibility of this plate permits the adaptation, which suits each ski, each skiing style and each technical level of the skier.

Abstract: The invention relates to a method and a device for producing a circumferentially closed hollow profile, a hollow-profile blank being expanded by means of fluidic internal high pressure in an internal high-pressure forming tool, after which said hollow-profile blank assumes the final shape of the hollow profile. In order to make it possible in a simple way to have a production of a hollow profile in which process reliability is ensured to a sufficient extent even in the case of high expansions of the hollow profile (higher than or equal to the breaking elongation of the material), it is proposed that, during expansion, the hollow-profile blank be supported, on at least one partial circumferential region, by means of at least one diaphragm fastened to the inside, facing the blank, of the tool and capable of being acted upon by a controllable pressure acting from outside, said diaphragm shifting back elastically as expansion progresses, with the supporting pressure acting on the diaphragm being reduced at the same time.

Title: Optical switch matrix with failure protection
Inventor: MACDONALD ROBERT I
IPC: H04Q11/00
Filed: 2002-02-01
Abstract: The present invention relates to a multi-stage non-blocking optical switch matrix having failure protection. The optical switch includes failure protection in the form of n capacity to provide an alternative route for any connection, including rearrangeable protection to provide alternative routes for multiple connections, as required, and to permit replacement of any failed submatrix module without service interruption. The present invention provides both internal and external protection from system failure in a multi-stage optical switch matrix by providing interconnected modules in a first external stage. The modules are interconnected by rerouting ports for redirecting signals from an input/output port on one external switch module to another external switch module. Protection is further provided through a center stage having a number of center stage switch modules, fully connected to the external modules, equal to twice the number of input/output ports and rerouting ports on an external module. With this structure, a failure at any point in the switch sub-matrices can be avoided, so that rearrangeable non-blocking performance can be obtained. In the case of a failure, a signal can be rerouted, additional signal paths can be rearranged, and faulty modules can be removed and replaced without affecting non-blocking switch performance.
