Publication number: 20110202486Abstract: Described herein is a framework for predicting development of a cardiovascular condition of interest in a patient. The framework involves determining, based on prior domain knowledge relating to the cardiovascular condition of interest, a risk score as a function of patient data. The patient data may include both genetic data and non-genetic data. In one implementation, the risk score is used to categorize the patient into at least one of multiple risk categories, the multiple risk categories being associated with different strategies to prevent the onset of the cardiovascular condition. The results generated by the framework may be presented to a physician to facilitate interpretation, risk assessment and/or clinical decision support.Type: ApplicationFiled: March 14, 2011Publication date: August 18, 2011Inventors: Glenn Fung, Faisal Farooq, Bharat R. Rao, Stephan B. Felix, Till Ittermann, Heyo K. Kroemer, Rainer Rettig, Henry Volzke

Patent number: 6190942Abstract: The invention concerns a process and a connecting arrangement for producing a chip card, wherein a semiconductor chip on a module is fitted in an opening in a card carrier with the attainment of an electrical and mechanical connection. In accordance with the invention, in place of connections which were hitherto necessary involving a force-locking relationship and/or involving the materials being bonded together, recourse is made to inductive and/or capacitive coupling between the module and the IC-card. For that purpose the module and the card correspondingly have coils and/or capacitive coupling surfaces for signal transmission purposes.Type: GrantFiled: June 9, 1999Date of Patent: February 20, 2001Assignees: PAV Card GmbH, Siemens AG, EVC Rigid Film GmbHInventors: Robert Wilm, Detlef Houdeau, Robert Reiner, Rainer Rettig
