  • Calibration-less direct capacitor-to-microcontroller interface 

    López Lapeña, Oscar; Serrano Finetti, Roberto Ernesto; Casas Piedrafita, Óscar (Institution of Electrical Engineers, 2016-02-18)
    Open Access
    A new technique to measure a capacitor or a capacitive sensor by means of a direct sensor-to-microcontroller interface circuit that does not need a calibration capacitor is proposed. Basically, the measurement process ...

  • Noise reduction in AC-coupled amplifiers 

    Serrano Finetti, Roberto Ernesto; Pallàs Areny, Ramon (2014-07-01)
    Restricted access - publisher's policy
    AC-coupled amplifiers are noisier than dc-coupled amplifiers because of the thermal noise of the resistor(s) in the ac-coupling network and the increased contribution of the amplifier input noise current i(n). Both ...
  • Technical specifications and system architecture of a compact weather station for rice blast field study 

    Pallàs Areny, Ramon; Casas Piedrafita, Óscar; López Lapeña, Oscar; Hornero Ocaña, Gemma; Serrano Finetti, Roberto Ernesto; Quílez Figuerola, Marcos; Polo Cantero, José; Cuadras Tomàs, Àngel; PEREIRAS, Jaime; PUIGDOLLERS, Pau (2014-03-17)
    External research report
    Restricted access - confidentiality agreement
    This report describes the work carried out as part of an EC-funded project called RICE-GUARD, which is developing a novel rice blast prediction tool based on an in-field wireless sensor network. Existing systems for ...
  • The QT scale: a weight scale measuring the QTc interval 

    Couderc, Jean-Philippe; Beshaw, Connor; Xiaodan, Niu; Serrano Finetti, Roberto Ernesto; Casas Piedrafita, Óscar; Pallàs Areny, Ramon; Rosero, Spencer; Zareba, Wojciech (Wiley, 2017-01)
    Open Access
    Despite the strong evidence of the clinical utility of QTc prolongation as a surrogate marker of cardiac risk, QTc measurement is not part of clinical routine either in hospital or in physician of fi ces. We evaluated ...
