The addition branch candidates are put into addition information parameters in the handover trigger signal, and the deletion branch candidates are put into deletion information parameters. To simplify processing on the network side, the network side separates the addition branch candidates from the deletion branch candidates, and carries out sequential processing of them independently.

Abstract: Selon la présente invention, un assemblage organisé de molécules fonctionnelles à fonctionnalité interfaciale spécifique (groupe(s) fonctionnel(s)) est fixé à des surfaces disponibles, y compris à l'intérieur des mésopores d'un matériau mésoporeux. Le procédé décrit permet d'éviter l'imprégnation de base normale qui entraînerait la digestion des parois entre les mésopores, et consiste à faire bouillir le matériau mésoporeux dans de l'eau en vue de la préparation de la surface, puis à ôter toutes les couches, à l'exception d'une ou deux, de molécules d'eau sur la surface interne d'un pore. Un précurseur moléculaire fonctionnel approprié est ensuite appliqué pour imprégner les pores hydratés, et ce précurseur subit ensuite une condensation pour former les molécules fonctionnelles sur la ou les surface(s) intérieure(s) du ou des pore(s).

Granted: 2006-01-31
Abstract: L'invention concerne un procédé et un dispositif d'imagerie tridimensionnelle comportant un capteur de mesure de distance qui est utilisé pour produire une série de profils d'une surface cible. Ces profils consistent en un ensemble de profils sensiblement parallèles et un autre ensemble de ce type de profils sensiblement parallèles, les profils d'un ensemble étant disposés de manière à former un angle par rapport à l'autre ensemble en vue de générer un grand nombre d'intersections de profils. Au niveau de chaque intersection, la distance la plus courte existant entre les profils est décelée et représente une contribution à une fonction d'énergie existant entre ces deux profils. Cette fonction d'énergie est définie comme la somme des contributions associées à toutes les intersections. Grâce à l'utilisation d'un modèle mathématique connu, les profils sont ensuite réorientés les uns par rapport aux autres de manière à réduire cette énergie totale. Ce processus peut être répété en vue d'obtenir une plus grande précision. Les derniers profils réorientés peuvent être utilisés pour définir la forme tridimensionnelle souhaitée de la surface cible.

Title: Interface system and method for asynchronously updating a shared resource
Inventor: MARCOTTE SCOTT T
IPC: G06F17/30
Filed: 1999-12-10
Granted: 2004-03-30
Abstract: Tasks make updates requested by calling tasks to a shared resource serially in a first come first served manner, atomically, but not necessarily synchronously, such that a current task holding an exclusive lock on the shared resource makes the updates on behalf of one or more calling tasks queued on the lock. Updates waiting in a queue on the lock to the shared resource may be made while the lock is held, and others deferred for post processing after the lock is released. Some update requests may also, at the calling application's option, be executed synchronously. Provision is made for nested asynchronous locking. Data structures (wait elements) describing update requests may be queued in a wait queue for update requests awaiting execution by a current task, other than the calling task, currently holding an exclusive lock on the shared resource. Other queues are provided for queuing data structures removed from the wait queue but not yet processed; data structures for requests to unlock or downgrade a lock; data structures for requests which have been processed and need to be returned to free storage; and data structures for requests that need to be awakened or that describe post processing routines that are to be run while the lock is not held.

Abstract: According to the invention multiple shared-memory processors (11) are introduced at the highest level or levels of a hierarchical distributed processing system (1), and the utilization of the processors is optimized based on concurrent event flows identified in the system. According to a first aspect, so-called non-commuting categories (NCCs) of events are mapped onto the multiple processors (11) for concurrent execution.  According to a second aspect of the invention, the processors (11) are operated as a multiprocessor pipeline, where each event arriving to the pipeline is processed in slices as a chain of internal events which are executed in different stages of the pipeline. A  general processing structure is obtained by what is called matrix processing, where non-commuting categories are executed by different sets of processors, and at least one processor set operates as a multiprocessor pipeline in which an external event is processed in slices in different processor stages of the pipeline.

Abstract: L'extension sans interruption de la capacité de commutation d'un système de communication présuppose l'extension du réseau de connexion comme constituant central. A cet effet selon l'état de la technique, le fonctionnement est arrêté et le réseau de connexion est entièrement déconnecté. Une fois le changement effectué, les liaisons interrompues sont rétablies, ce qui dans le cas de liaisons ATM, par exemple, engendre des coûts importants. Pour remédier à cela, l'invention réserve une place aux adresses de transmission de la principale étape d'extension tant dans la table de translation d'en-têtes des équipements interfaces que dans l'en-tête de chaque cellule ATM, et prévoit un éclatement de système, ce qui permet le remplacement progressif des anciens composants réseau de connexion par de nouveaux composants réseau de connexion. Les voies via les nouveaux composants réseau de connexion, dans la mesure où elles aboutissent aux mêmes équipements interfaces côté sortie, comme via les anciens composants réseau de connexion, peuvent être adressées par les mêmes adresses de transmission.
