N.70; Sato, R.M.V.70; Castro, A.L.S.71New fast plant system controllers are being designed and developed for ITER (International Thermonuclear Experimen-tal Reactor). They require to manage and to process massive data that is being acquired at high sampling rates. This data has to be archived for being posteriorly analysed in order to rebuild several aspects of the experiment. Our group is cur-rently involved in different works related with ITER, and more concretely related with their fast control technologies. ITER fast plant system controllers will require data archiving, and based on ITER requirements our group developed a data ar-chiving solution based on NetCDF-4 [1] [2] [3] technology. At this time, ITER is supporting HDF-5 [4] scientific file format, as data archiving solution for its control systems. In this sense, we have created a set of tests scenarios in order to analyse and compare both scientific data archiving solutions from ITER fast plant system controller requirements point of view.This paper presents a prototype of an acquisition board of electromyographic signals (EMG), an embedded portable so-lution, wireless and low cost. The system is composed of an EMG acquisition board, Zigbee and a device named GPRSx. After acquiring the EMG signal, it is sent through ZigBee wire-less technology to GPRSx device. The GPRSx device sends the EMG signal to a server on the Internet using GPRS wireless technology. The EMG signal is displayed in a graph on a com-puter simultaneously. The results are very promising and may serve as reference in studies for the biomedical area.Keywords— EMG;portable;wireless;low cost;ZigBee;GPRS.
