Abstract: L'invention concerne un procédé de transmission de paquets dans un cercle résilient à entrecroisement de paquets: au moins deux cercles résilients à entrecroisement de paquets s'entrecroisent sur deux noeuds d'intersection. Le noeud d'intersection reçoit un paquet de diffusion du premier cercle résilient et copie le paquet de diffusion; ce noeud d'intersection estime s'il est permis d'insérer le paquet de diffusion dans le second cercle résilient de paquets en élargissant le cercle conformément aux informations d'identification incluses dans le paquet diffusé copié et, si tel est le cas, l'insertion s'effectue dans le second cercle résilient de paquets par élargissement du cercle et par diffusion; sinon, on supprime le paquet diffusé, la condition de contrôle autorisant la diffusion par élargissement du cercle de tous les noeuds d'intersection étant nulle. L'invention permet d'assurer que, lorsque tous les noeuds d'intersection peuvent transmettre vers un serveur par un élargissement du cercle, cela évite une avalanche de messages diffusés par élargissement du cercle. L'invention s'applique dans le cas où plusieurs cercles résilients de paquets s'entrecroisent les uns les autres. Cette invention est facile à mettre en oeuvre et a une bonne compatibilité avec les réseaux existants. Ses coûts sont très faibles.

Abstract: A script analyzer with change guide generates accurate test scripts for evolving applications. Applications often have complex graphical user interfaces for which the permutations and combinations of GUI elements give rise to an enormous field of potential commands and command sequences to be tested. Furthermore, these applications change over time, rendering prior test scripts unworkable. The script analyzer automatically generates new test scripts to reliably test subsequent application versions, while greatly reducing the time, cost, and resource expenditures needed to arrive at subsequent application versions. A graphical user interface (GUI) application comparator helps application designers create error free graphical user interface applications (GAPs). The comparator finds differences in the GUI elements used to compose an interface between a current GAP version and a subsequent GAP version. One benefit is that a test script writer may better understand how the GAP has evolved in order to write a better test script. Another benefit is that the comparator output may be analyzed by subsequent processing systems for automated analysis of test scripts.

Title: Downhole wet connect using piezoelectric contacts
Inventor: O'MALLEY EDWARD J
IPC: H01R13/523
Filed: 2007-10-18
Granted: 2011-08-02
Abstract: A downhole wet connect uses a bearing relation between materials to take advantage of the piezoelectric effect between them. Voltage is applied from the surface to the uphole pad (14) which induces a voltage to be generated from the downhole pad (10) to a storage device (34) to store power for operating downhole equipment. The generated voltage can also be used as a real time power supply for downhole equipment. Alternatively, the generated voltage can be coded as a signal to downhole equipment to send date acquired downhole to the surface. The transmission of information is two way. Voltage input from the surface is stopped as downhole equipment sends a voltage based signal uphole for conversion by surface processors to capture the data. Alignment or downhole debris issues do not affect the transmission capability of the pads in the wet connect.
