Abstract: A system and method for transporting data packets in a ring network includes a plurality of network nodes having a protection switching agent and at least one fast downstream path circuit that provides a low-latency packet cut-through function for forwarding packets from an upstream node to a downstream node. The network nodes include three interfaces, two interfaces for coupling the network node to other network nodes in the ring network, and a third interface for coupling the network node to a local node. A plurality of virtual paths are provided between a data packet gateway, such as an Internet gateway, and the local nodes that are coupled to the network nodes of the ring network. A virtual channel identifier is embedded within data packets transported on the network so that the protection switching agent in each network node can determine whether to route received data packets to the local node, or to the low-latency cut-through downstream path circuit.

Abstract: Radio frequency identification elements (15), including linerless or lined labels (56), are produced with enhanced effectiveness. The antenna (18) is printed with conductive ink or toner, and cross-over may be provided by spot printing a non-conductive material (21) over a portion of the antenna and then printing a conductive cross-over element (25) on the non-conductive material (21). Typically the antenna (18) is printed on one face (22) of a web (10), and the radio frequency identification chip (30) is moved into contact with the opposite face (27) of the web (10) so that the contacts (31) penetrate the web and engage the antenna so that the web material acts as a dielectric. Alternatively part of the antenna on the first face may be over-printed with a non-conductive material (40) and the chip attached to the first face passing through openings (41) in, or penetrating, the non-conductive material (40) to engage the antenna. A protective substrate (45, 46) or coating is provide on at least one of the chip and antenna, for example by heating heat expandable microspheres, or applying a substrate having hot melt adhesive. The antenna may be printed with a printing media comprising a carrier including resin and wax and containing conductive material in it, and by heating the carrier so that it becomes fluid and is applied as a thick film on the substrate, and by allowing the carrier to cool so as to provide a conductive antenna. The printing may be accomplished at a speed of about 500 feet per minute or more.

Abstract: A server monitoring system monitors the performance of a web site or other Internet server system (24), as seen by users in multiple geographic access locations, (30) without the need for special monitoring software or hardware within such locations. Automated agents (22, 40) that run at a central data center (20) generate message traffic that is used to access and monitor the server system (24) from the multiple remote locations (30). The message traffic associated with a particular remote access location (30) is transmitted from the data center (20) to the remote location (30) across a dedicated link (32), such as an ATM link, and is routed onto the Internet at a corresponding Internet access point (30). The server response to each request message flows back to the data center (20) across the same link (32) as the corresponding request message. The remote access points (30) thus serve as virtual points of presence for monitoring purposes. Response times and other performance parameters are determined by the agents (22, 40) and aggregated within a database (26). Multiple data centers (20) may be interconnected such that each data center (20) services a particular continent or other region using a respective set of virtual points of presence (30).

Abstract: La présente concerne une famille de structures nodales pour la représentation d'objets tridimensionnels à l'aide d'images de profondeur. Ces structures nodales peuvent migrer dans un support MPEG-4 AFX aux fins de la représentation polygonale 3D conventionnelle. Les principaux formats de la famille nodale sont les suivants : Depthlmage, PointTexture et Octreelmage. Depthlmage représente un objet en établissant un lien entre ses images de référence et les cartes de profondeur correspondantes. PointTexture représente l'objet en tant qu'une série de points de couleur paramétrisés par projection sur une grille bidimensionnelle régulière. Octreelmage permet de convertir les mêmes données en un modèle de voxel à structure d'octants hiérarchique, un ensemble d'images de référence compactes et un arbre d'indices de correspondance d'images de voxel. Les formats Depthlmage et Octreelmage offrent des versions animées, où les images de référence sont remplacées par des flux de données vidéo. Les formats DIBR sont particulièrement commodes pour la construction de modèle tridimensionnel à partir d'une numérisation de longue portée 3D et des données vidéo de plusieurs sources. Le support MPEG-4 permet la construction d'un large éventail de représentations à partir des principaux formats DIBR, en plus d'offrir des outils souples pour le travail effectué directement sur des modèles 3D. La compression des formats DIBR se fait par l'utilisation de techniques de compression d'image (vidéo) sur les cartes de profondeur et les images de référence (flux de données vidéo).
