Low motor activity levels and prolonged episodes of uninterrupted immobility are characteristics of sleep. In clinical practice, the use of polysomnographic (PSG) recording is a standard procedure to assess sleep. However, PSG is not suitable for long-term monitoring in the home environment. This paper describes the development of a portable telemonitoring device that detects movements of a sub...

A portable device designed for in-field recording of biosignals is presented. The recorder is provided with three bipolar channels digitising at 200 Hz and lacks of interpretive intelligence. The captured data is send in real time via serial communication interface using AT commands, or stored in the internal memory for delayed transmission. Two operating modes are implemented: scheduled acquis...

During the last few years, technological development and acquired experience advanced and the echocardiogram has become an important and useful tool in intensive care unit environment. Data obtained from semi quantitative Doppler echocardiography (transthoracic and transesophageal) evaluation has contributed to an appropriate patient monitoring and management. Echocardiography as a diagnostic, ...

Many attempts have been made to automate the process through which vibration signals are analyzed to pinpoint a machine fault. Detailed diagnostic vibration analysis is often performed using portable spectrum analyzers that implement Fast Fourier Transform (FFT) mathematics on the vibration signal. In some instances, only a trained analyst can interpret the vibration data, effectively diagnose ...

The project’s idea is really simple: using the LabView environment, we have realized a virtual instrument able to get from the prototype data acquisition board for environmental monitoring parameters the information about air pollution factors like CO, H2S, SO2, NO, NO2 etc. In order to get effective information about those factors and the monitoring points, this intelligent measurement system,...

This work presents a miniaturized lab-on-chip system suitable for monitoring the activity of living cells through the on-chip detection of their bioluminescence emission. The system integrates amorphous silicon diodes, acting as temperature and light sensors, and indium tin oxide film, acting as heater, on a single glass substrate. During its operation, the glass is thermally and optically coup...

The Grid community has made an important effort in developing middleware to provide different functionalities, such as resource discovery, resource management, job submission or execution monitoring. As part of this effort this paper addresses the design and implementation of an architecture (CPPC-G) based on services to manage the execution of fault tolerant applications on Grids. The CPPC (Co...

In this paper, we present a new bio-impedance monitor for wearable and continuous monitoring applications. The system consumes less than 14.4mW when measuring impedance, and 0.9mW when idling. Its compact size (4.8cm × 3cm × 2cm) makes it suitable for portable and wearable use. The proposed system has an accuracy of 0.5Ω and resolution of 0.2Ω on both resistance (R) and reactance (X) measuremen...

This work is concerned with the design and realization of a complete telecare application for remote monitoring of patients at home, including a wireless monitoring portable device held by the patient and a remote central server application located in a surveillance center. Agitation, position and cardiac rate data are used for alarm decision and can be exploited by the central server applicati...
