Abstract: Method for manufacturing a plurality of pyroelectric sensors by forming a thin pyroelectric film or layer on one face of a silicon wafer or substrate, wherein electric polarization of this film is provided between lower and upper electrodes defining pixels forming these sensors. In order to protect the wafer in the event of a short-circuit between two electrodes of a pixel, resistors are arranged in series with the lower or upper electrodes by connecting these electrodes to each other by subsets in order to carry out the electric polarization. Once this polarization has been carried out, the electric connections connecting the upper or lower electrodes are removed to allow each pixel to supply an elementary electric signal when the sensor is operating. In order to minimize the risk of short-circuits and in order to reduce the stray capacity of the electrodes, the upper and lower electrodes of the pixels are structured.

Abstract: A system and a method for sterilizing objects, in particular medical instruments and accessories, using gas plasma, also called ionized gas. The gases used to form the plasma do not require to exhibit an intrinsic sterilizing activity. The sterilizing properties result from the passage through an electric field generating the plasma, an electric field which is provided by microwaves, a gas stream including oxygen in molecular form (O2) or as a gas element, and atomic or molecular species capable of emitting UV radiation once they have been energized. The system and method provide the advantage of making it possible to treat heat-sensitive and thermolabile objects at temperatures less than 50° C. using gases presenting no risks for the operator.

Abstract: A method of separating isotopes from polyatomic molecules, in particular 13C from trifluoromethane HCF3, by applying to the polyatomic molecules in the gas phase two infrared laser beams of different frequencies. The first laser has a frequency appropriate to excite a low overtone transition of a light atom stretch vibration and produce vibrationally pre-excited molecules enriched in the desired isotopes, for instance 13C. The second laser has a frequency and energy fluence to selectively induce dissociation of the vibrationally pre-excited molecules by infrared multiphoton excitation.
