Abstract: La présente invention concerne une approche pour gérer des sessions de communication de données par paquets entre des utilisateurs et un ou plusieurs services d'accès aux données, approche qui est utilisée pour créer, fournir et utiliser les services d'accès aux données, afin de contrôler et de commander des sessions de communication de données par paquets entre des terminaux mobiles (132) sur un réseau téléphonique mobile (120) et des fournisseurs de services (150) auxquels on peut accéder au niveau de ces terminaux mobiles, sur un réseau de transmission de données, par exemple sur Internet (140). Pour tout terminal mobile, de multiples interactions de service, qui peuvent se chevaucher dans le temps, peuvent être gérées pendant une période de temps au cours de laquelle le terminal mobile maintient la communication de données avec le système. Selon un aspect, cette approche caractérise une mise à disposition d'un service sur le noeud, qui consiste à configurer un point de détection pour ce service. Le noeud traite ensuite la communication. Ce traitement consiste à contrôler la communication, afin d'identifier des correspondances avec le point de détection configuré. Une fois qu'une correspondance avec le point de détection configuré est identifiée, une logique de service pour le service est avertie du point de détection.

Abstract: L'invention concerne un procédé de réduction du taux de diffusion de matériaux à libération lente à travers un matériau polymère hôte, permettant d'augmenter la durée de vie des matériaux à libération lente. On incorpore un matériau inorganique inerte à fines particules, du type matériau interstratifié à structure en couches, dans un mélange matériau à libération lente/polymère hôte. Le matériau interstratitifé présente des couches dans lesquelles sont intercalées des molécules de matériau à libération lente, logées dans des espaces compris entre les couches du matériau interstratifié. Le matériau particulaire abaisse le taux de diffusion du matériau à libération lente à travers le polymère hôte, par rapport au taux de libération observé en l'absence de matériau particulaire. Selon une variante, le matériau interstratifié renferme un nano-argile, et le polymère hôte est une polyoléfine, tandis que le matériau à libération lente est un matériau bioactif du type dinitroanaline. Le matériau à libération lente peut comprendre un appareil émetteur d'irrigation au-goutte-à-goutte, ou bien un tube, une bande ou un dispositif adjacent à cet appareil émetteur, pour la protection contre l'intrusion des racines. Le matériau interstratifié peut comprendre un nano-argile en couches qui résulte du contact entre de l'argile et un modificateur de surface, induisant la sorption et la complexation du modificateur de surface entre les couches adjacentes espacées de l'argile, suffisamment pour agrandir les espaces entre des plaquettes adjacentes. On effectue ensuite une exfoliation du matériau traité en surface pour séparer les plaquettes, puis on mélange les plaquettes exfoliées avec le matériau polymère afin d'obtenir une matrice polymère à partir de laquelle il est possible d'élaborer des produits pour l'irrigation au goutte-à-goutte.

Abstract: Disclosed are a group III-nitride semiconductor substrate and a production method therefor. A group III-nitride semiconductor substrate having an element-forming surface with a dislocation density of 10 7  cm -2  or less in its entirely is formed only two steps. In a first step, a AlGaN-based low-temperature buffer layer is formed on a ZrB 2  single crystal base having a defect density of 10 7  cm -2  or less, at a base temperature allowing the low-temperature buffer layer to be grown or deposited on the ZrB 2  single crystal base substantially without creation of any Zr - B - N amorphous nitrided layer. Subsequently, in a second step, an AlGaN-based single crystal film is grown directly on the low-temperature buffer layer. The present invention can fully bring out the properties of the ZrB 2  single crystal base having a high potential as a base material capable of lattice marching with group III-nitride semiconductors, so as to achieve a high-quality AlGaN semiconductor layer with an element-forming surface having a low dislocation density, through a fully simplified process.

Abstract: L'invention concerne un système et un procédé permettant d'envoyer des signaux haute-fidélité depuis une première station sans fil (20) jusqu'à une deuxième station sans fil (30). Lesdites stations sans fil peuvent fonctionner selon la norme Bluetooth. Dans la première station sans fil (20), une première représentation d'un signal audio est envoyée directement depuis un dispositif d'entrée audio (52) jusqu'à un CODEC (62). Une deuxième représentation du signal audio passe par un dispositif de retardement de sorte que, en arrivant au niveau du CODEC, celle-ci soit déphasée par rapport à la première représentation. Après échantillonnage et codage (62), les signaux numériques sont envoyés à la deuxième station sans fil (30) au moyen de deux canaux synchrones différents d'une liaison sans fil (40). Au niveau de la deuxième station sans fil (30), les signaux reçus de chaque canal sont décodés (62) et des signaux analogiques sont produits. Le signal audio provenant d'un des canaux passe par un dispositif de retardement (56) afin de le ramener dans la phase par rapport au signal en provenance de l'autre canal. Les signaux analogiques sont ensuite envoyés à un dispositif de sortie audio (58) et peuvent être évalués par exemple par un système de reconnaissance vocale.
