Title: Procedes et appareil permettant de choisir des trajets multiples en tenant compte d'un risque partage
Inventor: PIEDA PETER STEVEN
IPC: H04L12/56
Filed: 2002-06-04
Abstract: L'invention concerne des procédés, des systèmes et des supports pouvant être lus par ordinateur, qui facilitent le choix de trajets multiples à travers un réseau représenté par une topologie de réseau qui tient compte d'un risque partagé pouvant exister entre des ressources de réseau. Le procédé selon l'invention consiste à identifier un premier trajet à travers la topologie de réseau, à partir d'un noeud source jusqu'à un noeud destination, le premier trajet comprenant une première séquence de ressources réseau. Pour au moins un groupe à risque partagé, une détermination est réalisée si l'un des groupes à risque partagé comprend la première séquence de ressources réseau, le groupe à risque partagé étant un groupe de ressources réseau contenu dans la topologie de réseau présentant un risque partagé. La topologie de réseau est transformée en une topologie virtuelle qui dissuade l'utilisation de ressources réseau dans tout groupe à risque partagé déterminé. Un deuxième trajet à travers cette topologie virtuelle est identifié à partir du noeud source vers la destination. Ce procédé peut être conçu pour favoriser le caractère disjoint des noeuds et/ou des bords.

Abstract: A method for dividing a frame structure for a mobile telephone system which operates in half-duplex, i.e. in which the transmission and reception of signals in a mobile takes place within mutually separate time-slots. Each frame includes three time-slots, each intended for transmission and reception.  According to the method, the frame structure is divided so that transmission first takes place in a transmission time-slot.      Reception then takes places in a reception time slot which is separate from the transmission time-slot. subsequent to reception (RX), the frame structure includes an idle time (t1) which remains until further transmission takes place in the next-following frame. The method enables the frequency synthesizer of the mobile in the reception direction to be set to a channel different to the reception channel and then to be reset accurately to the reception channel.

Abstract: IMPROVED FIBER OPTIC GYROSCOPE               Abstract of the Disclosure An improved fiber optic rotation sensing technique and an improved optical fiber gyro are provided which exhibit increased sensitivity to and linearity of rotation measurement by using a special dual-section, counter-wound fiber coil for measuring the Sagnac phase shift resulting from rotation of the coil.  The optical fiber coil has a plurality of turn and is formed of at least two separate interconnected coil sections each having a predefined number of turns of fiber.  In the gyro arrangement, the separate sections are axially disposed adjacent to each other in such a way that the direction of winding of the turns in one of the coil sections is counter to the direction of winding of the turns in the other of the coil sections.     The plurality of turns in each coil section is selected to be such that the sum of the effective lengths defined thereby is sufficient to realize the desired gyro modulation frequency.  At the same time, the Sagnac phase shift for a given rotation rate is made proportional to the difference between the effective lengths of the coil sections and remains within a desired threshold level even if the overall effective length of the fiber coil is increased.

Title: Spray deposition
Inventor: LEATHAM ALAN G
IPC: C23C4/123
Filed: 1990-11-27
Abstract: ABSTRACT          There is provided a method of spray deposition in which a stream of liquid metal or metal alloy is atomised inside a spray chamber into a spray of atomised droplets.  A metal or metal alloy collector is rotated about an axis transverse to the mean axis of the spray and in the path of the spray so that a deposit is formed about the collector with a bond between the deposit and the collector sufficient to isolate the interface from oxygen penetration.  The collector is then retained as an integral part of the final product and further processed to substantially eliminate porosity in the region of the bonded interface.  The collector may then be removed or retained as desired.  The collector and the deposit may be the same or different materials and the bond between the deposit and the collector is preferably enhanced by plasma heating in the region if disposition.          The invention also provides a plant for carrying out the preferred method arc plasma heating.
