Abstract: L'invention concerne un procédé d'exploitation (EXP) d'un réservoir géologique au moyen d'un modèle de réservoir cohérent avec un modèle géologique (MG). Pour ce procédé, on construit plusieurs modèles de réservoir (MRn) au moyen de différentes méthodes de mise à l'échelle. Grâce à une étude de connectivité, menée à partir d'un algorithme permettant de résoudre le problème du plus court chemin (DIS) appliqué aux maillages, on identifie les chemins d'écoulement principaux entre les puits pour le modèle géologique (MG) ainsi que pour les différents modèles réservoir (MRn). On sélectionne alors le modèle réservoir (MR) pour lequel les longueurs des chemins principaux d'écoulement entre puits sont les plus proches de celles obtenues pour le modèle géologique de départ.

Title: Cavopulmonary viscous impeller assist device and method
Inventor: RODEFELD MARK D
IPC: A61M60/871
Filed: 2012-12-03
Abstract: A bearingless and sealless rotary blood pump is disclosed which provides multidirectional flow intended to provide low-pressure, high-volume right-sided partial assist circulatory support in a univentricular Fontan circulation on a permanent basis. The pump includes a housing and an impeller suspended in the center of the housing. The housing incorporates flow optimization features between inlet and outlet ends, as well as with the impeller surface. Large fluid gaps maintained between impeller and housing eliminate any potential for blood flow obstruction. The impeller contains some motor components. It includes a central stator and surrounding rotor. The motor includes a brushless DC outrunner electrical motor design. An electromagnetic stator core is surrounded by a circumferential passive magnetic ring. The rotor is further levitated about the stator spindle by a plurality of axially and radially located passive magnetic and hydrodynamic journal bearings on both ends of the spindle. The rotor is bearingless and sealless. During impeller rotation, blood entering the space between the rotor and stator is induced to flow by centrifugal pumping action and the fluid film separates the stator hydrodynamic bearings from the rotor so that there is no direct mechanical contact between the rotor and stator.

Abstract: The present invention describes a computerized business method for placing, accepting and authenticating the completion of a purchase order for a service via a communications network. A service provider uploads a variety of information to a server system that may include age, sex, geographic location, height, likes, Facebook friend statistics, twitter followers, Linkedin connections, etc. The service requester then provides access to a selected digital payment method to the server system that will allow the server to release payment to the service provider from the service requester upon completion of the selected service or task. The service requesters are given access to the service providers information and the service requesters are provided with a means to filter the server database of the service requesters for specific criteria.  Each service requester uploads the description of a specific task or set of tasks that they wish to have a service provider complete for them, the period of time they need it completed and the reward or payment offered for completion. The service requesters request is then sent to the filtered selection of service providers to be accepted or rejected. If request is rejected the process ends, but if the service provider accepts the service request, they perform an action that will notify the server system that they have accepted the request.  The service provider will upload digital authentication or proof to the server that the service has has been completed by providing one or more forms of digital content that authenticates that the service provider has completed the selected task or tasks at one or more timely intervals. Payment will then be released to the service provider with confidence that they have completed the selected task(s).
