Title: Methods and systems for handling subscriber data
Inventor: RUNE JOHAN
IPC: H04W8/18
Filed: 2000-08-24
Abstract: Subscriber data in a Super-charged network is handled in a network including a home network entity containing information regarding subscriber in the network and one or more visitor network entities containing subscriber to other networks. A subscriber profile in a visitor network entity may be updated if necessary, and if certain conditions are met. The profile may be updated by sending modifications from the home network entity to the visitor network entity. Depending on the amount of time that has elapsed since the contact of the subscriber and the network, the subscriber's identity may be unallocated.  If the subscriber's record is purged from a visitor network entity, an indication of this may be recorded in the home network entity.

Abstract: A network and method for efficiently and effectively acquiring broadcast content, such as multimedia data, from content providers (24) and delivering the acquired content to end users via a tiered network (12) to minimize congestion during content delivery to thus provide high quality of service.  The network and method employ a tiered Internet-based network that is served by a hybrid satellite/optical fiber data distribution network. The network includes a data center (18) to which data, such as streaming video, audio or multimedia data, is provided over a content acquisition network by content providers. The data center uplinks the data to at least one satellite, such as a geosynchronous earth orbit (GEO) satellite, and over an Internet or asynchronous transfer mode (ATM) network (30), which distributes the data to the servers in the tiered network (12). The tiered network in this example comprises three tiers, although any number of tiers is acceptable. The three tiers are referred to respectively as master data centers (master data center tier) (18), regional data centers (regional data center tier) (16), and media serving centers (media serving center tier) (14) that are interconnected by a private asynchronous transfer mode (ATM) network. A data director in the data center in cooperation with the ATM network determines which tier of servers can best fulfill a data request by an end user while minimizing the amount of hops required to provide such data.

Abstract: Procédé qui permet de déterminer une caractéristique d'un mélange à base de boue entourant un outil de forage introduit dans un trou de forage. Ledit procédé consiste à faire tourner l'outil dans le trou de forage. De l'énergie provenant d'une source d'énergie qui se trouve dans l'outil est appliquée dans le trou de forage. Des signaux de mesure sont reçus par un capteur placé dans l'outil, en provenance d'un site situé autour du trou de forage. La section transversale du trou de forage est séparée en au moins un premier et un deuxième secteur. Un premier signal de mesure provenant du premier secteur correspond à l'énergie de retour qui résulte de l'interaction entre l'énergie appliquée et le mélange à base de boue. Un deuxième signal de mesure provenant du deuxième secteur correspond à l'énergie de retour qui résulte de l'interaction entre l'énergie appliquée et les formations. Une indication d'une caractéristique intrinsèque du mélange à base de boue est dérivée des premiers signaux de mesure associés au premier secteur du trou de forage.
