Abstract: La régulation de gain d'un amplificateur optique dopé à l'erbium et à régulation de gain se réalise par verrouillage de gain d'une cavité laser à un niveau égal à la perte globale de la cavité et par réglage de la longueur d'onde de résonance de l'amplificateur en fonction d'une première longueur d'onde. Lorsqu'un signal optique à amplifier caractérisé par une longueur d'onde différente de la première longueur d'onde traverse l'amplificateur, le gain de signal produit par l'amplificteur est fonction non de l'intensité du signal mais du gain de cavité. L'amplificateur présente une sensibilité minime aux variations de température ambiante car la première longueur d'onde est sélectionnée pour correspondre à la crête de la somme de la surface de captation et de la surface d'émission d'erbium.

Title: Subscriber authentication for radio local loop system
Inventor: GORDON MALCOLM
IPC: H04W12/06
Filed: 1997-02-28
Granted: 2000-12-26
Abstract: The network security of a radio local loop system is highly desirable to avoid fraudulent use of the network by unauthorised users with appropriate subscriber equipment. For fixed subscribers, the propagation delay between base station (1) and subscriber unit (3) will also remain fixed and, provided this is measured with sufficient accuracy, the distance from the subscriber to the base station can bedetermined. This can be used as an aid to the authentication of a subscriber. Other signal characteristics which are indicative of the physical location of a purported subscriber can be used, such as directional information. In a system in which propagation delay has to be monitored anyway, for other purposes, such as orthogonal CDMA code synchronisation, or for a TDM system, added security can be obtained without great extra cost.

Abstract: Système de diagnostic pour capteur optique comprenant une source (9) de bande de longueur d'onde étroite réglable qui envoie de la lumière (44) de longueur d'onde variable dans une fibre optique (32, 52). Des capteurs réfléchissants (54, 58) tels que des réseaux de Bragg sont disposés le long de la fibre (52) sur le chemin de la lumière variable (44). Les capteurs (54, 58) transmettent la lumière (56, 60) dont la longueur d'onde de transmission minimum varie en raison d'une perturbation telle que la contrainte qu'elle subit. Un circuit (42) de commande du syntonisateur excite la source (9) de lumière réglable de sorte que la lumière (44) de la source balaie une plage de longueur d'onde prédéterminée pour éclairer chaque capteur à sa longueur d'onde de transmission minimum. La puissance de la lumière transmise est convertie en un signal électrique par un détecteur (64) et surveillée par un processeur (68) de signal qui détecte les éventuelles baisses du niveau de puissance transmises et envoie des signaux de sortie sur les lignes (71) qui indiquent la perturbation subie par chaque capteur. Ce système peut être configuré suivant un mode à boucle ouverte pour mesurer les contraintes statiques ou suivant un mode à boucle fermée pour rechercher les contraintes statiques et mesurer les contraintes dynamiques. Ce système peut également être utilisé dans une configuration de Fabry-Perot pour constituer alors un système très sensible de détection des contraintes; il peut, en outre, être configuré suivant un mode de réflexion ou de transmission.

Abstract: An offshore fluid transfer system (10) is provided, of the type that includes a riser (32) having an upper end (34) connected through a universal joint (36) to a turret (22) on a vessel and having a lower end (36) anchored by catenary chains (40), and that also includes hoses (70, 71) each extending from a base (50, 58) on the seafloor to the turret on the vessel, which avoids the need for a complicated hose structure to pass fluid across the universal joint. A fluid coupling (73) near the bottom of the turret, which is widely spaced from the universal joint, connects to a hose that extends from the fluid coupling in a sinuous path down to the seafloor base. The long length of hose, enables it to bend when the vessel drifts, to avoid excessive hose tension or riser contact during such vessel drift. A riser connector (102) can be operated to disconnect the riser from the turret so the riser can sink. The fluid coupling can include a fluid connector (100) which can separately disconnect the hose from the turret. A ring-shaped holder (80) connected to the hose lies around the axis of the turret and around the riser.

Abstract: A propulsion system for accelerating and directionally controlling a fluid having a continuous dynamic surface (40) for circulating through a fluid from an entrainment region (44) where fluid is introduced to the dynamic surface (40) to a thrust region (46) where fluid is discharged from the dynamic surface (40).
