Publication number: 20170319126Abstract: Mechanical vibrations induced by the heart of the foetus, together with other vibrations coming from the body of the pregnant mother, are sensed by the at least one electro-mechanical transformer placed on the body surface of the pregnant mother, the vibrations are transformed into electrical signals and processed. The electrical signals are pre-amplified, frequencies including the heart sound of the pregnant mother are removed from amplified electrical signals of the perceived vibrations by active bandpass filtering, the signal level reduction due to bandpass filtering is compensated for by amplification, and the filtered signal is transferred to a device for processing and evaluation. A device suitable for implementing the method, and a computer-readable medium are proposed, the latter comprising instructions to be run on the device, e.g. the smartphone, for processing the measured signals, displaying them visually, showing trends and making proposals to the user based on the processed signals.Type: ApplicationFiled: May 2, 2017Publication date: November 9, 2017Inventors: Gábor SIPKA, Márta FIDRICH, Tibor SZABÓ, Tamás NAGY, Vilmos BILICKI, György BÁRTFAI, Tamás BITÓ, Róbert MINGESZ, Zoltán GINGL, Tibor GYIMÓTHY, Gergely VADAI, Gergely MAKAN, Melinda VÁNYA, Mária JAKÓ, Ráhel ZÖLEI-SZÉNÁSI, János BORBÁS

Patent number: 8355553Abstract: A system and process for analyzing multidimensional data characterizing a least a portion of a subject is described. An input module accepts at least one multidimensional dataset which is derived from any of several types of data sources. A registration module accepts the dataset from the input module and registers the dataset from the input module to a selected anatomical model to provide a registered dataset. A processing module is coupled to the registration module and uses this in determining a core region and associated core region information, and computes threshold characteristics of the registered dataset. A segmentation module accepts the registered dataset and the core region information from the processing module, and segments the registered dataset to provide a segmented description of an organ from the registered dataset and core region information, where the segmented, registered dataset describes characteristics of the organ of the subject.Type: GrantFiled: November 22, 2008Date of Patent: January 15, 2013Assignee: General Electric CompanyInventors: Márta Fidrich, Laszlo Rusko, György Bekes
