      We present and discuss a solution to the growing demand for satellite telecommunication coverage in the high-latitude geographical regions (beyond 55°N), where the signal from geostationary satellites is limited or ...

    • Signal-to-motion artifact ratio versus frequency for impedance pneumography 

      Rosell Ferrer, Francisco Javier; Webster, John G. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1995-03-01)
      Article
      Accés obert
      We measured transthoracic impedance between 12.5 and 185 kHz in nine adults. We used a system with two impedance channels, both simultaneously detecting the real part of impedance at two different frequencies. We used only ...
