  • Publication number: 20250135734
    Abstract: A system and method for molding a fiber reinforced composite part are disclosed. The system includes a mold with electrical contacts that make electrical contact with at least one monitoring circuit incorporated in a fiber preform disposed in the mold so that the resistance of the monitoring circuit can be monitored as resin fills the mold cavity and envelopes the preform. The method includes monitoring the resistance of at least one monitoring circuit incorporated into a fiber preform disposed in a mold to determine the location of the resin flow front as resin is injected into the mold and surrounds the fiber preform.

  • Publication number: 20080312959
    Abstract: The present invention is directed to a health care data management system comprising a workflow management system and a decision support system, as well as to a corresponding computer program product and a method. The decision support system comprises a probabilistic expert system for medical advice and is arranged to create a query to be sent to the workflow management system. It is also arranged to receive a corresponding answer determined by the workflow management system. This answer comprises entity allocation data relating to the allocation of an entity handled by the workflow management system. Furthermore, the decision support system is arranged to utilize the data as probabilistic input variable(s) for the expert system. Such a system has the advantage of combining up-to-date patient data and organisational data (resource allocation), which is managed by the workflow management system, with the profound medical expertise of a decision support system.
