  • Patent number: 10299692
    Abstract: Disclosed are various embodiments of invasive and non-invasive systems for electrophysiological mapping of a patient's heart, where cardiac action potentials (APs) on a myocardial surface of a human heart are reconstructed. In one embodiment, the APs are reconstructed using known electrical potentials on the myocardial surface in combination with known geometries of the heart and/or the torso. A mathematical model of cardiac electrical activity may be employed that takes into account homogeneous and isotropic intracellular, extracellular, and human body electrical conductivities.

  • Patent number: 9976369
    Abstract: A round-trip autoclave sample-extracting device for extracting a sample at a sample extraction location of a geological formation, the device includes a self-closing pressure chamber module for receiving the sample. The pressure chamber module is connected to a lifting module in order to lift the sample into the pressure chamber module in one sampling stroke. The round-trip autoclave sample-extracting device has a triggering module and a pressure regulating module, the triggering module acting on the lifting module in order to trigger the sampling stroke, and the pressure regulating module is coupled to the pressure chamber module at least on the pressure side after the sampling stroke in order to influence a pressure in the pressure chamber module. A round-trip method is proposed which includes a first trip and at least one second trip for extracting a sample while maintaining a pressure that is present at the sample extraction location.
