Patent CA-2314960-A1 (CA)
Inventor: TAWIL SALEEM
IPC: H04N7/20
Filed: 1998-12-15
Abstract: Une antenne de réception satellitaire (16) sur un site utilisateur (14) reçoit d'un satellite (12) des signaux satellitaires d'une première fréquence. Les signaux satellitaires se propagent le long d'un chemin de signal satellitaire (42) à l'intérieur d'un angle d'observation de part et d'autre de l'axe (28) de l'antenne (16). Un émetteur terrestre (20) émet des signaux sous une première fréquence le long d'un chemin de propagation radio (40) allant l'émetteur au site utilisateur (14). Par rapport au site utilisateur (14), l'émetteur terrestre (20) est situé de façon que le chemin de propagation radio (40) forme avec l'axe (28) de la première antenne (16) un angle relativement grand. L'angle du chemin de propagation radio (40) avec l'axe de l'antenne satellitaire (28) est assez grand pour que les signaux terrestres présents sur le site (14) produisent, en provenance de l'antenne (16), des signaux d'entrée terrestres d'un niveau inférieur au niveau d'interférence des signaux d'entrée satellitaires produits par l'antenne. Ainsi, les signaux terrestres n'interfèrent pas avec les signaux satellitaires, même s'ils utilisent une même fréquence d'émission.

Filed: 2001-05-03
Abstract: A self-propelled upright vacuum cleaner is provided having a lower portion and an upright handle portion pivotally attached to the floor engaging portion for a pivotal motion between an upright storage position and a pivotal operating position including a transmission operatively connected to a drive wheel and a motor drivingly connected to the transmission for driving the drive wheel in forward and reverse. A clutch engaging member is pivotally mounted to the floor engaging portion adjacent to the transmission for pivotal motion about a pivot axis located generally at a forward portion of the clutch engaging member.    Operably associated with the clutch engaging member is a transverse linking member that reciprocates from a neutral position in first and second directions in response to pivotal motion of a bottom link. The reciprocation of the transverse link selectively moves said clutch engaging member from a neutral position to a forward drive position and a reverse drive position. A finger link member carried on the housing assembly is selectively positioned in a channel formed on the bottom link, relative to the pivotal positioning of the housing assembly.  Pivotal motion of the finger link engages the bottom link member when the housing assembly and handle portion are in an operative inclined position and does not engage the bottom link member when the housing assembly and handle portion are in a storage upright position.

Patent CA-2349520-A1 (CA)
Inventor: SCHMIDT DOUGLAS CHARLES
IPC: H04L45/122
Filed: 1999-10-29
Abstract: L'invention concerne plusieurs noeuds informatiques qui communiquent au moyen d'une source IP et des adresses de destination d'aspect aléatoire et (éventuellement) un champ sélectif d'aspect aléatoire. Des paquets de données respectant des critères définis par une fenêtre mobile d'adresses valables sont acceptés pour un nouveau traitement, tandis que les paquets de données qui ne satisfont pas auxdits critères sont rejetés. Outre les "sauts" des adresses IP et des champs sélectifs, des sauts peuvent être imprimés à des adresses de matériel, telles que des adresses du contrôle d'accès au support. Les adresses ayant effectué des sauts sont générées par des générateurs de nombres aléatoires présentant des longueurs de séquence non répétées facilement déterminées à priori, lesquelles peuvent effectuer un saut en avant rapide en séquence en un nombre arbitraire d'étapes aléatoires, et présentent la propriété de rendre difficile l'estimation des nombres aléatoires futurs si l'on ne connaît pas les paramètres du générateur de nombres aléatoires. Des techniques de synchronisation peuvent être mises en oeuvre pour rétablir la synchronisation entre des noeuds d'émission et des noeuds de réception. Ces techniques incluent une technique d'auto-synchronisation dans laquelle un champ de synchronisation est transmis comme partie intégrante de chaque paquet, et une fonction de "point de contrôle" grâce à laquelle des noeuds d'émission et des noeuds de réception peuvent avancer jusqu'à un point connu en accomplissant leur fonction de saut. L'invention concerne également une technique de rejet de paquet rapide fondée sur l'utilisation de vecteurs de présence.
Patent CA-2356683-A1 (CA)
Title: Compact refrigeration system
Inventor: BUTSCH OTTO R
IPC: F25B49/02
Filed: 1999-12-21
Abstract: A selectively controllable valve (106) is arranged in a refrigeration circuit which interconnects the evaporator (102) and the condenser (100) and is controlled so that a pressure differential is built up across the valve (106).  The valve (106) is selectively opened to allow "batches" of working fluid to pass therethrough. In some embodiments, the working fluid which is allowed to pass through the valve (106), is heated in a chamber (116) to increase the amount of pressure on the downstream side of the valve (106). This produces expanded pressurized working fluid which increases the pressure in the condenser (100) and forces previously condensed and liquefied working fluid through a flow restricting transfer device (104) into an evaporator (102). In other embodiments, the pressure differential is produced and/or augmented by a pump (102) such as a piston pump, or a combination of the pump (102) and the heating chamber (116).
