Patent CA-2248055-A1 (CA)
Inventor: DINGSOR ANDREW D
IPC: H04B1/40
Filed: 1997-05-05
Abstract: Procédé, dispositif et article servant à corriger les erreurs de fréquences de porteuse. Un signal de modulation de fréquence est reçu par une antenne et transmis à un récepteur. Ce récepteur admet le signal de modulation de fréquence à la fréquence de porteuse et émet un signal de bande de base. Ce signal de bande de base est ensuite traité par un processeur de signaux numériques (301) effectuant la correction et le décodage de la fréquence de porteuse afin de produire un flux de données qu'un microprocesseur transmet à un ordinateur central. Les différences entre la fréquence de porteuse de modulation de fréquence et la fréquence utilisée pour démoduler le signal de modulation de fréquence peuvent déplacer le niveau de polarisation de courant continu du signal de bande de base. Le processeur de signaux numériques (301) corrige cette différence de fréquence au moyen d'une valeur de correction de réception appliquée ensuite à chaque échantillon de signal reçu. La transmission des données s'effectue depuis l'ordinateur central vers le processeur de signaux numériques (301) par l'intermédiaire d'un microprocesseur (103). Le processeur de signaux numériques (301) effectue le codage et la correction de fréquence de porteuse des données afin de fournir un signal de bande de base à un émetteur (303) qui module ce signal de bande de base afin de produire un signal de modulation de fréquence à la fréquence de porteuse souhaitée. Les différences de fréquence entre la fréquence souhaitée de modulation de fréquence et la fréquence utilisée afin de moduler le signal de bande de base peuvent produire des erreurs dans les systèmes récepteurs. Le processeur de signaux numériques (301) corrige cette différence de fréquence au moyen d'une valeur de correction d'émission qu'il applique ensuite à chaque échantillon de signal codé.

Abstract: Abbreviated dial number table and special number table are provided in external memory in control unit of digital button telephone system.  For each of abbreviated dial numbers, the abbreviated dial number table stores a destination phone number prefixed with a special number concerning whether notice of a call originating party identification number should be permitted.  For each of destination identification numbers, the special number table stores the special number.  At call origination, it is determined whether dial data is an identification number of destination or an abbreviated dial number.  If the dial data is an abbreviated dial number, reference to the abbreviated dial number table is made, dial data prefixed with the special number according to the destination is read out, and sent to the trunk line.  If the dial data is an identification number of destination, reference to the special number table is made, the special number registered in the table is added to the identification number of destination, and resultant dial data is sent to the trunk line.  In both the case, it becomes unnecessary to determine whether notice of the call originating phone number should be permitted according to the destination, and accordingly adding the special number as occasion demands before dialing the identification number of destination.
Patent CA-2255760-A1 (CA)
Inventor: TSENG SUSAN YEN-TEE
IPC: C12Q1/68
Filed: 1997-05-09
Abstract: The invention describes a method for the identification of a target bacteria from a sample isolated from a complex matrix such as food and enriched for the presence of the target. The method employs a method of picking colonies cultured from the sample such that the DNA from the cells may be immediately subjected to primer directed amplification after picking and without further processing.

Abstract: Cette invention se rapporte à un procédé permettant d'annoncer à un abonné appelant dans un système émetteur d'appels (31) d'un réseau de télécommunications radios (30) qu'un abonné appelé d'un système serveur (34) n'est pas disponible. On débute ce procédé en envoyant un message de sollicitation de demande d'acheminement (RoutReq) (37) du système émetteur d'appels au système serveur. Ce message de sollicitation RoutReq contient un paramètre de capacités de transaction (61) indiquant que le système émetteur d'appels est capable de générer des annonces. Le système serveur détermine alors que l'abonné appelé n'est pas disponible. Ledit procédé se poursuit par l'envoi d'un message de sollicitation de demande de réacheminement (RedReq) (44) du système serveur au système émetteur d'appels. Le message de sollicitation RedReq contient un paramètre de liste d'annonces (62) demandant au système émetteur d'appels de faire une annonce (47) à l'abonné appelant, et il peut contenir un paramètre de langue préférée (64). Le message de sollicitation RedReq contient également un paramètre d'autorisation de transfert à numéro (65), si l'abonné appelé a souscrit à des services nécessitant un soutien logique de service. Toute jonction ayant fait l'objet d'une prise par le système émetteur d'appels à destination du système serveur est alors libérée. Enfin, le système émetteur d'appels envoie l'annonce (47) à l'abonné appelant, pour lui annoncer que l'abonné appelé n'est pas disponible. Si un paramètre de langue préférée à été reçu, le système émetteur d'appels fait l'annonce dans la langue préférée indiquée.

Title: Method and apparatus for producing gas occlusion-free and void-free compounds and composites
Inventor: VIDAURRE-HEIREMANS VICTOR
IPC: B01F29/60
Filed: 1998-05-21
Abstract: The present invention discloses a generic method for producing void- and gas occlusion-free materials, as well as apparatuses for batch and continuous production of same. This generic method can be utilized in the production of a wide variety of polymeric compounds and composites and specifically encompasses the two ends of the polymeric composite spectrum, that is, polymer concretes on the one hand, and fiber-reinforced polymer composites on the other. The composite materials of the present invention are characterized by visual count as being void- and gas occlusion-free to the level of 1 micron at 1250x magnification. Concomitantly, the invention produces useful polymer concrete materials which exhibit substantially improved integrity for easy machining at high speeds, and high dielectric and mechanical strength, as compared with composite materials produced by conventional methods. Thus, one particularly well-suited application for the materials of the present invention is the class of high voltage electrical insulating materials and insulators where the presence of voids, or gas occlusion flaws, may have deleterious effects, leading to their early failure.
