Patent CA-2409511-A1 (CA)
Title: Procede et dispositif permettant de detecter des arcs electriques accidentels
Inventor: STEFFEN PETER
IPC: G01R31/12
Filed: 2000-05-20
Abstract: La présente invention concerne un procédé permettant de détecter des arcs électriques accidentels (arc tracking) sur un câble (1), notamment sur un câble d'un réseau électrique se trouvant à bord d'un avion. Selon ce procédé, un signal de courant alternatif détecté (I(t)) est échantillonné en temps discret, puis une fonction trigonométrique (I(k)) imitant l'allure du courant alternatif est déterminée par interpolation d'un certain nombre de valeurs d'échantillonnage (y(k)). La fréquence réelle du courant alternatif (.omega.) est alors déduite de cette fonction trigonométrique. Le résultat d'une comparaison de la fréquence réelle du courant alternatif (.omega.) avec une fréquence théorique ou de référence (.omega.') est utilisé afin de déterminer la présence d'un arc électrique accidentel (I¿SA?,I¿GA?) et un signal d'avertissement (S¿arc?) est éventuellement produit. Il est avantageux d'intégrer un dispositif fonctionnant selon le procédé de cette invention dans un disjoncteur (7) destiné à un réseau électrique se trouvant à bord d'un avion, ce disjoncteur étant conçu pour détecter et interrompre un arc électrique accidentel apparaissant sur un câble (1) dudit réseau électrique.

Title: Method for determining the optimum pre-compensation in an optical transmission system
Inventor: WAH KEE LENG
IPC: H04B10/18
Filed: 2001-06-14
Abstract: Methods, media and signals for determining optimum pre-compensation in an optical system. A first method involves receiving a pre-compensation ratio value representing a ratio of dispersion and length to optimum pre-compensation, for a span of optical medium in said optical system and producing a system pre-compensation value as a function of dispersion and length of each span in said optical system such that differences between actual pre-compensation and optimum pre-compensation in each span of said system are minimized. A second method involves producing an optimum pre-compensation value Pwdm by balancing power profiles in the positive and negative chirped regions of the system, for pulses emitted into an optical medium of the system. A method of optimizing performance of an optical system, using pre-compensation is also disclosed.

Title: Cable failure device for garage doors and the like
Inventor: BEAUDOIN MICHEL
IPC: E05D13/00
Filed: 2003-02-19
Abstract: A cable failure device for a cable-operated door operated by a tensioned cable, the cable-operated door having a movement guided along a fixed structure, such as a guide rail. The cable failure device is configured for cooperating with the tensioned cable so as to immobilize the cable-operated door with respect to the fixed structure in the event of a loss of tension in the cable. The cable failure device included a support bracket for mounting the cable failure device onto the door, a guiding assembly operatively mounted for guiding the movement of the door along the fixed structure, and a braking assembly operatively mounted onto the support bracket, and operable between a rest position where the guiding assembly is allowed to guide the door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tension cable where the braking assembly engages a portion of the fixed structure for braking movement of the cable-operated door with respect to the fixed structure. The cable failure device also includes a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect the given loss of tension. The safety arm is operable between a safety configuration where it is positioned over at least one fastener of a corresponding hole of the support bracket when there is still a given tension in the tensioned cable, for preventing a user from removing the support bracket from the door, and a retracted configuration where the safety arm is positioned away from the fastener when the given tension is no longer present in the cable, thereby enabling the user access to the fastener. Thus, the cable failure device is configured for immobilizing the door in the event of a loss of tension and for preventing a user from removing the device from the door when there is still tension in the cable.
