In this work we present an innovative algorithm for the dynamic control of ventricular assist devices (VADs), based on the acquisition of continuous physiological and functional parameters such as heart rate, blood oxygenation, temperature, and patient movements. Such parameters are acquired by wearable devices (MagIC & Winpack) and sensors implanted close to the VAD. The aim of the proposed algorithm...
OL-JADE is an on-line method for fetal ECG extraction from non-invasive potential recordings, able to work in real-time on a DSP. With respect to the original JADE algorithm, it exploits a recursive sample-by-sample approximated centering and whitening stage that partially violates the requirements of the subsequent JADE stage. In this paper this aspect is investigated showing a comparison with another...
Fetal ECG (FECG) extraction from non-invasive biopotential recordings is strongly affected by the intensity of the FECG contribution to the input signals. The higher the FECG contribution the higher the SNR and consequently the quality of the separation. The definition of a subject-specific good electrodes positioning is an open issue. In this paper we present a technique based on the fetal ECG extraction...
Fetal ECG (FECG) extraction from maternal abdominal potential recordings is a task of paramount importance for pediatric cardiologists, but there is a lack of established solutions for it. In this paper the real-time implementation of a block-on-line independent component analysis (ICA) algorithm for FECG extraction is presented and evaluated over real long lasting recordings. The problem of the signals...
