  • Wireless ECG and heart rate monitoring using dual ground dry electrodes 

    Gómez Clapers, Joan; Casanella Alonso, Ramón (2010)
    Conference lecture
    Open Access
    In this work, a novel wireless easy-to-use measuring system is presented to acquire the Lead I ECG signal and the heart rate. The system presents a novel application of the dual ground configuration to dry electrodes, ...

    An augmentative and alternative communication (AAC) device for people with speech disabilities is presented. This AAC system exhibits the advantages of two currently used systems: 1) usability of the communication boards ...
  • Irreversible entropy model for damage diagnosis in resistors 

    Cuadras Tomàs, Àngel; Crisóstomo, Javier; Ovejas Benedicto, Victòria Júlia; Quílez Figuerola, Marcos (American Institute of Physics (AIP), 2015-10-28)
    Article
    Open Access
    We propose a method to characterize electrical resistor damage based on entropy measurements. Irreversible entropy and the rate at which it is generated are more convenient parameters than resistance for describing damage ...
  • Determination of a System’s Entropy Using Pyroelectric Sensors 

    Cuadras Tomàs, Àngel; Ovejas Benedicto, Victòria Júlia (2015-12)
    Article
    Open Access
    We propose a system for measuring entropy variations, S, in thermal systems using pyroelectric sensors. These sensors convert time-dependent temperature variations into electrical current. Consequently, heat and ...

    Pallàs Areny, Ramon; Casas Piedrafita, Óscar (2015)
    Article
    Open Access
  • A fast method to estimate body capacitance to ground at mid frequencies 

    Aliau Bonet, Carles; Pallàs Areny, Ramon (University of Oslo, 2015-12-18)
    Article
    Open Access
    Impedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a fast method to estimate that apacitance at 10 kHz, which is valid for impedance ...
  • Effects of stray capacitance to ground in three electrode monopolar needle bioimpedance measurements 

    Kalvøy, Håvard; Aliau Bonet, Carles; Pallàs Areny, Ramon; Martinsen, Ørjan G (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference lecture
    Open Access
    Positive phase angle is documented and analyzed in a three electrode monopolar needle measurement. Inductance equivalent behavior of the stray capacitance to ground is described as error source in a non-inductive sample ...
  • Automatic Concealed Heart Rate Detection from the BCG in Seated Position 

    Luna Lozano, P. S.; Pallàs Areny, Ramon (2015-03-01)
    Article
    Open Access
    Continuous monitoring of health state is important in elder and chronically ill (but otherwise not critical) patients. Ideally, the patient should not be aware of being continuously monitored. This study describes an ...
  • Report on RICE-GUARD Market Requirements and Preliminary System Specifications 

    KATSANTONIS, Dimitris; DRAMALIS, Christos; Pallàs Areny, Ramon; Casas Piedrafita, Óscar; López Lapeña, Oscar; PUIGDOLLERS, Pau; PEREIRAS, Jaime (2013-12-20)
    External research report
    Open Access
    This report outlines the work carried out as part of the EC-funded project called RICE-GUARD. The project concerns the development of a novel in-field system which is going to be capable of continuously monitoring weather ...
  • Sensortizació en aplicacions alimentàries 

    Pallàs Areny, Ramon (2015-04-22)
