Unveiling the biometric potential of finger-based ECG signals. [PDF]
Comput Intell Neurosci, 2011 The ECG signal has been shown to contain relevant information for human identification. Even though results validate the potential of these signals, data acquisition methods and apparatus explored so far compromise user acceptability, requiring the acquisition of ECG at the chest. In this paper, we propose a finger‐based ECG biometric system, that uses

A High‐Performance Stand‐Alone Solar PV Power System for LED Lighting
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 This paper presents new improvements and real result of a stand‐alone photovoltaic power system for LED lighting that was developed previously. The actual system, during day, charges a lead acid battery using MPPT algorithm for power transfer optimization, and, during night, it supervises battery discharge and controls the current in the power LED ...

Compact, Frequency Reconfigurable, Printed Monopole Antenna
International Journal of Antennas and Propagation, Volume 2012, Issue 1, 2012., 2012 This paper proposes a possible implementation of a compact printed monopole antenna, useful to operate in UMTS and WLAN bands. In order to accomplish that, a miniaturization technique based on the application of chip inductors is used in conjunction with frequency reconfiguration capability.
