Patent CA-2312054-A1 (CA)
Title: A traffic shaper that accomodates maintenance cells without causing jitter or delay
Inventor: PETTY NORMAN W
IPC: H04L12/56
Filed: 2000-06-22
Abstract: A traffic shaper (121 ) accommodates F5 maintenance cells of an ATM constant bit rate (CBR) virtual circuit without causing jitter or delay of the CBR traffic cells. Each virtual circuit is allocated two queues: a first queue (131) for enqueuing CBR traffic cells and a second queue (132) for enqueuing maintenance cells. Each virtual circuit is allocated twice its normal bandwidth on the transmission medium (120). A dequeue state machine (140) transmits contents of each first queue at twice the normal transmission rate during one half of each normal transmission interval of the queue's corresponding virtual circuit, and transmits contents of each second queue at twice the normal transmission rate during the other half of each normal transmission interval of the queue's corresponding virtual circuit. F5 cell transmissions are thus locked half-way between, and 180° out of phase with, transmissions of sequential CBR traffic cells, and consequently introduce no jitter or delay, at the expense of allocated bandwidth.

Patent CA-2333538-A1 (CA)
Inventor: LAMOTHE BRADLEY A
IPC: B60K5/12
Filed: 1999-05-21
Abstract: A motor coach is provided having a supporting structure arranged to mount an engine assembly thereon. Isolator mounts mount the engine on the supporting structure for permitting limited relative movement therebetween. Inertia transmitting means in the form of a pair of links are mounted between the engine and the supporting structure. The links connect to the front end of the engine and extend generally horizontally to the supporting structure for substantially restricting the motion of the front end of the engine to upward and downward deflections. The inertia of the engine assembly (20) thus constrains the structural motions of the motor coach, creating a significant dynamic stiffening effect in the primary natural vibration structural bending mode of the motor coach.

Title: Communication terminal apparatus and cell search method
Inventor: ARIMA TAKENOBU
IPC: H04W36/00
Filed: 2001-02-21
Abstract: Threshold judging circuit 151 performs a threshold judgment on a correlation value output from each of search correlators 104-1 to 104-n. Rank determining circuit 152 ranks phases output from threshold judging circuit 151 in descending order of correlation value. Candidate path determining circuit 153 determines a phase with a high correlation value in the short integration as a candidate path to assign to one of search correlators 104-1 to 104-n sequentially, and outputs a control signal for generating an operation clock based on an assignment result to clock generator 106. Demodulation phase determining circuit 154 determines a candidate path with a highest correlation value in the long integration to be optimal for use in demodulation, and outputs a control signal for generating an operation clock based on a determined result to clock generator 106. It is thereby possible to perform a cell search fast without increasing a hardware scale.

Abstract: L'invention concerne des procédés et un appareil permettant à des dispositifs différents d'échanger des informations sur un réseau informatique, qui comportent le stockage d'une base de données de dispositifs d'émission et de réception compatibles à un serveur de vérification. Un premier dispositif produit un signal de demande d'autorisation d'envoi, qui est comparé au serveur à la base de données stockée et, en cas de correspondance, un signal d'autorisation d'envoi est produit par le serveur. Avant qu'un échange complet puisse se produire, un signal de demande d'autorisation de réception est produit au deuxième dispositif en réponse à la réception du signal de communication provenant du premier dispositif. Le signal de demande d'autorisation de réception est comparé à la base de données située au serveur et, en cas de correspondance, un signal d'autorisation de réception est produit par le serveur, ce qui déclenche la réception du message provenant du premier dispositif par le deuxième dispositif. Une fonction de traduction est de préférence prévue avant l'étape de déclenchement de la réception du message provenant du premier dispositif par le deuxième dispositif, cette fonction pouvant être liée à des différences de matériel, de protocoles de logiciel, de sécurité de réseau, de normes de communication nationales/internationales, de langues ou à d'autres facteurs, le cas échéant.
