Title: Procede de suppression d'interferences parallele a double ponderation
Inventor: WEI LIMEI
IPC: H04B1/707
Filed: 2002-10-09
Abstract: L'invention concerne un procédé de suppression parallèle à double pondération dans un système de communication mobile AMRC. Ce procédé allie la pondération partielle et la pondération s'inspirant de la règle de Bayes. Lorsqu'un symbole de l'utilisateur lui est attribué, le facteur de sécurité de fonctionnement du résultat est calculé selon l'algorithme de pondération s'inspirant de la règle de Bayes; le signal de régénération du symbole de l'utilisateur est pondéré à l'aide du facteur de sécurité de fonctionnement. Lors de l'estimation des interférences multi-accès et de leur suppression, on obtient l'interférence multi-accès de l'utilisateur que d'autres utilisateurs rencontrent en pondérant le signal de régénération à l'aide du niveau de la carte à puce d'autres utilisateurs; puis on définit une valeur pondérale par pondération de l'interférence multi-accès obtenue au moyen de la valeur pondérale. Finalement, on soustrait l'interférence multi-accès pondérée du signal reçu. Il s'agit en fait de la suppression partielle de l'interférence multi-accès des utilisateurs. L'invention concerne également un procédé de suppression d'interférences parallèle à double pondération utilisé avec l'algorithme simplifié consistant à modifier la pondération du niveau de la carte à puce et obtenir une pondération du niveau des symboles au moyen du procédé d'attribution linéaire de fragment ou du procédé de consultation de table au lieu de l'attribution tangente hyperbolique.

Abstract: Es wird ein Verfahren zum anisotropen Ätzen von Strukturen in einem Halbleiterkörper, insbesondere von mit einer Ätzmaske lateral exakt definierten Ausnehmungen in einem Siliziumkörper (18), mittels eines Plasmas (28) vorgeschlagen. Dabei wird an den Halbleiterkörper zumindest während eines über eine vorgegebene Zeitdauer andauernden Ätzschrittes eine Ionenbeschleunigungsspannung angelegt, die insbesondere über eine hochfrequente Wechselspannung induziert wird. Die Zeitdauer des Ätzschrittes ist weiter in mindestens zwei Ätzabschnitte unterteilt, zwischen denen die angelegte Ionenbeschleunigungsspannung jeweils verändert wird. Bevorzugt sind zwei Ätzabschnitte vorgesehen, wobei während des ersten Ätzabschnittes eine höhere Beschleunigungsspannung verwendet wird als währen des zweiten Ätzschrittes. Die Länge des ersten Ätzabschnittes kann weiter dynamisch oder statisch während der Ätzschritte mittels einer Vorrichtung zur Detektion eines Polymerdurchbruchs bestimmt werden. Zur Erzeugung und Einstellung der Höhe der Beschleunigungsspannung werden weiter bevorzugt hochfrequente Impulse bzw. Impulspakete mit einstellbarem Impuls-Pause-Verhältnis eingesetzt.

Inventor: BOECKING FRIEDRICH
IPC: F02M59/46
Filed: 2000-08-10
Abstract: The invention relates to a hydraulic control device (14), especially a hydraulic control device for an aggregate for injecting fuel into the combustion chamber of an internal combustion engine. The inventive control device (14) has an externally controlled actuator (24) and a valve member (22) interacting therewith. Said valve member controls the pressure medium connections between at least one channel (18) that carries a high-pressure medium and one channel (20) that carries a low-pressure medium and determines the injection parameters. The aim of the invention is to provide a hydraulic control device that allows injection of the fuel in several stages. To this end, the valve member (22) has at least two valve seats (36.1 and 36.2) which are controlled by separate closing members (26.1 and 26.2). Said closing members are mounted to be displaced relative to each other and to be actuated in the same direction. The invention facilitates a multi-stage injection with a single control of the actuator (24) and thereby reduces the control frequency and heat build-up of the actuator (24).

Title: Neutronenoptische bauelementanordnung zur gezielten spektralen gestaltung von neutronenstrahlen oder -pulsen
Inventor: MEZEI FERENC
IPC: G21K1/00
Filed: 2003-01-22
Abstract: Für viele Anwendungen, beispielsweise für Strukturuntersuchungen mittels Neutronenstreuung, werden langsame Neutronen benötigt, die durch Abbremsung mittels geeigneter Moderatoren aus schnellen Neutronen erzeugt werden. In bekannten Anordnungen wird an den Experimentierplätzen ein Neutronenstrahl zur Verfügung gestellt mit jeweils einem Einzelspektrum (kalt, thermisch oder heiß), das von Neutronen mit dem benötigten Energiebereich, aber geringfügig auch von den beiden anderen Energiebereichen gebildet wird. Eine Flexibilität für unterschiedliche Anwendungen mit verschiedenen Neutronenenergien ist hier nicht gegeben. Bei der erfindungsgemäßen neutronenoptischen Bauelementanordnung (NOA) werden die Strahlengänge (CBL, TBL) der einzelnen Moderatoren (CNM, TNM) gezielt zusammengeführt, sodass ein überlagerter Neutronenstrahl (SBL) mit einer wirksamen, mittleren Strahlrichtung (EBL) entsteht. Der überlagerte Neutronenstrahl (SBL) weist ein Multispektrum auf, das sich aus den Einzelspektren mehrerer Moderatoren (CNM, TNM) zusammensetzt. Dadurch wird eine größere spektrale Breite erreicht, mit der verschiedene Anwendungen in unterschiedlichen Energiebereichen der Neutronen möglich sind. Durch weitere neutronenoptische Bauelemente (NOC), insbesondere in Form eines energieabhängig schaltenden Superspiegels (SSM), kann das Multispektrum durch Schaltung zwischen Moderatoren sowohl hinsichtlich der Intensität als auch der Strahlqualität noch verbessert werden.
