Patent CA-2284870-C (CA)
Inventor: QUANT FREDERICK R
IPC: G01P5/18
Filed: 1998-03-17
Granted: 2003-11-25
Abstract: L'invention concerne un système d'analyse électro-optique d'un aérosol, comprenant un laser à onde entretenue (24), destiné à produire deux faisceaux (26a, 26b) dans la gamme de longueurs d'onde rouge, ces faisceaux croisant un flux de particules (20) à des emplacements légèrement espacés. Un laser ultraviolet pulsé (38) produit un faisceau qui vient croiser ledit flux de particules à un troisième emplacement, situé en aval des deux premiers. L'énergie laser diffusée par chaque particule lorsqu'elle traverse les deux premiers emplacements est utilisée pour calculer la taille aérodynamique des particules et la durée de pulsation du laser ultraviolet (94), de sorte que le faisceau ultraviolet irradie systématiquement la particule qui traverse l'emplacement situé en aval. En réponse à leur irradiation, les particules renfermant des matières biologiques ou d'autres composants fluorescents émettent des signaux de fluorescence. Le système fournit ainsi des informations relatives à la composition et à la taille de ces particules.

Abstract: Un message est transmis à un système serveur de poursuite en réponse à la mise en référence par un système client d'un localisateur de ressources prédéterminé correspondant à une ressource extérieure à ce système serveur de poursuite. Ce dernier permet indirectement au système client de posséder un élément d'information pouvant être sélectionné par ce système client, sur lequel cet élément d'information est identifié graphiquement au moyen d'un contenu d'information pouvant être obtenu auprès d'un système serveur de contenu par l'intermédiaire de la mise en application d'un localisateur de ressources de contenu. Cet élément d'information comprend un localisateur de ressources de poursuite référençant le système serveur de poursuite et identifiant les données de l'élément d'information. La sélection de cet élément d'information provoque l'utilisation par le système client du localisateur de ressources de poursuite afin de transmettre les données au système serveur de poursuite et d'utiliser le localisateur de ressources de contenu, de manière à obtenir le contenu d'information auprès du système serveur de contenu.
Patent CA-2298923-C (CA)
Inventor: HOOK RICHARD WAYNE
IPC: A01B61/04

Granted: 2003-09-16
Abstract: A spring trip standard for a tillage implement includes a coil spring freely compressed between an upper spring-abutting surface on the mounting bracket and a tower spring-abutting surface on a casting which is connected by a transverse pivot to the mounting bracket. A tool supporting shank is bolted to the casting and biased downwardly into a ground working position by the spring. The casting includes an integral downstop extending forwardly from the pivot. The downstop contacts the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. A positive upstop limits upward pivoting of the casting to prevent spring breakage or permanent deformation of the spring. Shoulder areas on the casting contact rear edges of the mounting bracket to limit upward pivoting.

Title: Random access in a mobile telecommunications system
Inventor: EDVARDSSON MARIA
IPC: H04W88/08
Filed: 1999-08-17
Granted: 2009-07-21
Abstract: A method for processing multiple random access requests is disclosed in which a base station (204) transmits an acquisition indicator signal (A), which indicates that the base station (204) has detected the presence of a random access transmission (P,M). The acquisition indicator (A) can be generated based (212) on the amount of energy received (210) on the random access channel (e.g., as opposed to the correct/incorrect decoding of a random access message). Consequently, the delay between the beginning of the random access transmission (P,M) and the beginning of the acquisition indicator transmissions (A) is significantly shorter than the delay to the beginning of an acknowledgement transmission based on the reception of a correctly decoded random access message. If a mobile station (202) does not receive a positive acquisition indicator (A), it should interrupt the present transmission and start to retransmit the random access burst in the next time slot, while modifying the transmission power level accordingly between the successive re-transmissions.

Abstract: A method and apparatus of automatically reprocessing a specimen for microscopic exam-ination is disclosed. Processing of a specimen for microscopic examination involves fixation of the specimen and preparation of the embedded specimen from the fixed specimen. There are instances where, once a specimen has been pro-cessed, it is necessary to reprocess the specimen due to contamination of reagents during process-ing or inadequate fixation. The system automati-cally reprocesses a specimen by removing resid-ual embedding material from the specimen with a clearing agent, removing the clearing agent with a dehydrating agent, and removing the dehydrat-ing agent with an aqueous fluid.

Abstract: Cette invention se rapporte à un système de fichier réparti qui attribue de façon intelligente des parties d'un système de fichier (22) d'un serveur (10) à une ou plusieurs stations clients (12) sur un réseau (20). Les données du système de fichier utilisées pendant la mise sous tension d'une station client (12) peuvent être stockées dans la station client (12). Une extraction du système de fichier (22) peut ensuite être exécutée, dans la mesure où la station client (12) a la capacité de stocker le système de fichier (22). Une opération multidiffusion, effectuée sous la forme d'une opération d'arrière-plan dans la station client, peut être utilisée pour extraire le système de fichier (22). Pour les parties du système de fichier (22) qui ne sont pas attribuées à la station client (12), celle-ci peut toujours accéder au système de fichier depuis le serveur (10). La largeur de bande du réseau peut ainsi être réduite et l'accès au système de fichier par les stations clients peut être d'une manière générale plus efficace.
