Abstract: The invention relates to a method, a network, a boundary node and a server for restricting the traffic in a packet-oriented, connectionless network for an efficient QoS transmission of prioritized data packets. According to the invention, reliability checks are carried out that include a reliability check with respect to the network input and the network output. The reliability checks allow to check whether resources meeting the requirements to transmission of a group of data packets of a priority class are available in the network. The invention allows to avoid resource shortages, especially at the network input and network output, thereby safeguarding QoS transmission.

Title: Method for coating a substrate with calcium phosphate
Inventor: BUHRMEISTER MISCHA
IPC: A61F2/28
Filed: 2002-12-06
Abstract: The invention relates to a novel method for coating substrates with calcium phosphate. Prior art methods do not permit temperature-sensitive substrates or particles to be coated with calcium phosphates or it requires several method steps for carrying out this coating. The aim of the novel method is to be able to carry out a simple coating for all materials as well as for particles. To this end, the invention provides that the substrate to be coated is placed in a calcium phosphate gel, whereupon this substrate that is coated with the gel is dried. Afterwards, the calcium phosphate particles not adhering to the substrate are removed. According to the invention, the substrate can also be placed inside a colloidal solution of SiO2 containing a calcium phosphate, whereupon the mixture is constantly set in motion, the solvent is removed, and the substrate is provided with a calcium phosphate layer by condensing the colloidal SiO2 on the surface of the substrate. The coated substrates can, particularly when it concerns coated particles, be used as bone substitute material.

Title: Procede de synchronisation d'evenements, notamment pour des processeurs de systemes a tolerance d'erreur
Inventor: PELESKA PAVEL
IPC: G06F11/16
Filed: 2003-08-06
Abstract: La présente invention concerne des cartes processeurs de construction plusieurs fois identique, à fonctionnement en mode synchrone, qui sont destinées à des systèmes redondants. L'exigence fondamentale pour la mise en oeuvre d'un système à mode synchrone est le comportement déterministe de tous les composants contenus dans la carte, c'est-à-dire les unités centrales, les jeux de puces, la mémoire centrale, etc. Le comportement déterministe signifie que ces composants fournissent des résultats identiques aux mêmes moments lorsqu'il n'y a pas d'erreur, si les composants obtiennent des stimuli identiques aux mêmes moments. Le comportement déterministe implique également l'utilisation d'interfaces synchrones. Des interfaces asynchrones impliquent souvent dans le système certaines incertitudes temporelles qui empêchent de maintenir le comportement global synchrone du système. L'objectif de la présente invention est de pouvoir mettre en oeuvre un mode synchrone. Cet objectif est atteint au moyen d'un procédé de synchronisation d'événements externes qui sont transmis à un module (unité centrale) et influencent celui-ci. Selon ce procédé, les événements externes sont stockés de façon temporaire par des éléments de mémoire tampon. Les événements externes stockés dans les éléments de mémoire tampon sont appelés dans un mode de fonctionnement séparé du module afin d'être traités par une unité d'exécution (EU) du module. Le module entre dans ce mode de fonctionnement qui s'active à la satisfaction d'une condition prédéfinissable ou prédéfinie reflétant la quantité d'instruction exécutée.

Abstract: La précision de la détermination de position d'un appareil de communication sans fil peut être affectée négativement par une polarisation Doppler GPS non imputée, pouvant à son tour affecter des estimations et des mesures Doppler GPS effectuées par l'appareil de communication sans fil. La qualité de ces mesures est très importante pour la détermination de position étant donné qu'une qualité insuffisante peut empêcher l'appareil de communication sans fil d'acquérir des satellites dans les modes les plus sensibles présentant des bandes de fréquence étroites, ce qui se traduit par des mesures de pseudodistance GPS. Une polarisation Doppler GPS non imputée, importante, affecte également la détermination de position du fait de l'influence négative sur la propagation temporelle de mesure de phase de code GPS par rapport à la durée habituelle avant utilisation dans la détermination de position. Ceci est également valable dans le cas de Doppler de code CDMA en raison de l'effet négatif sur la propagation temporelle de mesure de phase de code AFLT par rapport à la durée habituelle avant utilisation dans la détermination de position. Cet effet est le problème le plus important dans le cas de grandes fenêtres de recherche. Par conséquent, l'invention concerne un procédé d'optimisation de détermination de position à base GPS en présence d'erreurs de fréquence variant dans le temps, consistant à mesurer et/ou calculer en continu la polarisation Doppler GPS et la polarisation Doppler de code CDMA résultantes, et à minimiser leurs effets négatifs par rapport à la détermination de position, par recentrage de fenêtres de recherche Doppler GPS sur la base de la valeur de polarisation Doppler GPS, et utilisation des valeurs de polarisation Doppler GPS et de polarisation Doppler de code CDMA afin de propager correctement des mesures de pseudodistance GPS et de phase pilote AFLT, respectivement, par rapport à la durée habituelle avant utilisation dans la détermination de position.
