A group of professors of the Laboratory of communications and integration of the microelectronics ( LACIME) of the ÉTS collaborated in the conception of a new sub-system of insulation against the vibrations in microgravity ( MVIS) with the Canadian Space agency. The MVIS produces a magnetic field capable of maintaining in suspension a packaging of average size inside which diverse scientific experiments can be made. This device was aboard the shuttle Atlantis which took off last February and was settled in the international Space station The noise and the vibrations are important inside this station. The systems of ventilation, the mooring of space vehicles and the work of the astronauts sometimes make vibrate the orbital complex of research. These vibrations can damage scientific experiments dedicated to the study of the effects of the microgravity. The MVIS allows to avoid that the experiments undergo these harmful effects. When it will be settled in the station, the experiments led inside the new device, as those who concern the flow of the fluids, the growth of crystals and the development of metallic alloys, will not be any more submitted to the shocks and to the vibrations.To control electromagnets generating the magnetic field of the MVIS, it was necessary to be able to sample the signal of accelerometers very precisely. It is of what made a success the researchers of the LACIME by working out digital analog converters of extreme precision for the MIVS. The previous MVIS had a dynamic range of 100 decibels, while the new covers 140 decibels. Within the framework of this research, professors Jean Belzile, François Gagnon and Naïm K. Batani, of the Department of electric engineering, applied for the patent High-Precision Digital to Analog Converter. Professor Ammar B . Kouki, René Jr Landry and Claude Thibeault also participated in the research works.
