Abstract: Les cellules d'un réseau de radiotéléphones sont couvertes par des empreintes de faisceaux crées par un système d'antennes à faisceaux multiples. Des canaux aller de liaison suivent les unités mobiles dans leurs déplacements entre les empreintes de faisceaux. De plus, chacune des cellules est divisée en zones fonction de la configuration du trafic des mobiles à l'intérieur de la cellule. On se trouve normalement en présence d'une zone de forte densité couverte par plusieurs empreintes de faisceaux de surface réduite, d'une zone de densité moyenne couverte par deux ou trois empreintes de faisceaux de surface moyenne, et d'une zone de densité faible couverte par une empreinte de faisceau étendue. Alors que la configuration du trafic évolue au cours de la journée, l'antenne à faisceaux multiples reconfigure la disposition des zones et des empreintes de faisceaux pour chacune des cellules, de manière à constituer une configuration quasi optimale de zone et d'empreintes de faisceaux en dépit de l'évolution de la répartition du trafic.

Title: Improved durability flame stabilizing fuel injector
Inventor: MORFORD STEPHEN A
IPC: F23C7/00
Filed: 1999-03-23
Abstract: The invention is a tangential entry, premixing fuel injector (10) for the combustion chamber (30) of a turbine engine. The injector includes a pair of arcuate scrolls (18) defining the radially outer boundary of a mixing chamber (28) and a pair of air entry slots (36) for admitting a stream of primary combustion air tangentially into the mixing chamber. The scrolls also include an axially distributed array of primary fuel injection passages (42) for injecting a primary fuel into the primary air stream. A  flame stabilizing fuel injector centerbody (46) includes an impingement and transpiration cooled outlet nozzle (50) for introducing secondary fuel and secondary air into the combustion chamber. The nozzle (50) includes an impingement plate(74) with an array of impingement ports (76) and a tip cap (104) with an array of discharge passages (106). The impingement ports and discharge passages are in series flow, misaligned relationship so that secondary air exiting from the impingement ports impinges on the tip cap and flows through the core discharge passages to impingement cool and transpiration cool the nozzle. The disclosed injector runs cooler than a more, conventional tangential entry injector and therefore is more durable. The improved durability is achieved even though the disclosed injector uses less cooling air than a more conventional tangential entry injector and discharges the cooling air at a lower velocity. The reduced cooling air quantity helps to minimize carbon monoxide emissions and the reduced discharge velocity improves the spatial and temporal stability of the combustion flame.

Title: Segmented scintillation detector for photon interaction coordinates
Inventor: MOISAN CHRISTIAN
IPC: G01T1/20
Filed: 1998-02-05
Abstract: The present invention relates to light guides (1) capable of encoding the transverse and longitudinal coordinates of light emission induced by the interaction of photons in an array of a plurality of the light guides. Each light guide has at least two discrete crystal segments (4) adjacently disposed along a common longitudinal axis of the light guide (1). Between adjacent segments is a boundary layer (7) having less light transmission than the light transmission of the crystal segments (4). A light absorbing mask (8) increases light adsorption in a segment (4). Photons enter the light guide (1) and cause the emission of scintillation light which is delivered in different and resolvable quantities to light sensing devices. The differences in quantity of delivered light is caused by successive decreases in light transmission to light transmitting end (5) caused at least in part by the boundary layers (7).    The differences in quantity of light establish the segment from which the light emission took place.

Title: Arrangements to detect and respond to disturbances in electrical power systems
Inventor: RUTA JOSEPH W
IPC: H02H7/26
Filed: 1999-08-16
Abstract: A control arrangement and method is provided for detecting and responding to disturbances in electrical power systems. In a preferred arrangement, an integration is initiated that is based on a comparison of actual voltage of a source and a reference voltage. When the integration exceeds a predetermined value, the source is considered unreliable. Also in a preferred arrangement, a determination is made as to whether or not the disturbance is a downstream fault condition. For example, this is useful for applications where a transfer is made from a first source to a second source when predetermined disturbances are detected. In this manner, the transfer of the load to a second source is avoided which would continue the supply of the downstream fault. Additionally, the arrangement distinguishes between various degrees of disturbances to permit appropriate response based on the severity and type of disturbance. For example, a first immediate response, i.e. without intentional delay, is provided for more severe disturbances while a second delayed response is provided for less severe disturbances. The control arrangements transfers the load to an alternate source of power via the use of a high- speed source-transfer switching system that both avoids undesirable current flow between sources and minimizes undesirable transfer delays.
