Abstract: The invention relates to a method for regulating, by means of a computer, a resistive element arranged to deice and/or demist a support, the method comprising:
a) a loop for monitoring the temperature T and the moisture level H at the support;
b) a deicing and/or demisting sequence which, as long as the temperature T and the moisture level H monitored by the monitoring loop a) are indicative of an absence of frost or mist on the support, keeps the resistive element inactive and, in the contrary case, demands, in a step b2), the circulation of a current I in the resistive element so that the latter dissipates a thermal power Pth, adjusted according to the temperature T and the moisture level H, and providing deicing or demisting of the support over a predetermined period Dp.

Abstract: A method for controlling a submersible environmental sensor, the sensor including a support having a face which includes a sensitive zone configured to receive at least one species of interest (SOI), anti-fouling means configured to cause at least the sensitive zone to vibrate, and detection means for detecting a presence of the SOI on the sensitive zone, the detection means and the anti-fouling means being carried by the support, wherein the anti-fouling means includes actuators configured to cause the medium to vibrate in a standing mode with a wavelength 3-20 times the size of the SOI to confine the SOI on the sensitive zone, includes activating the anti-fouling means in a de-fouling mode, stopping the anti-fouling means, activating the anti-fouling means to confine the SOI in the sensitive zone, and stopping the anti-fouling means. The method also includes activating the detection means and stopping the detection means.

Abstract: A concentration sensor for at least one biological species in the blood includes a support, at least one waveguide, and an optomechanical resonator suspended from the support. The optomechanical resonator is optically coupled to the waveguide, and the optomechanical resonator is configured to vibrate in volume mode and includes at least one face extending in the plane of the sensor and configured to receive molecules of the given species. At least the face includes a functionalisation layer specific to the species, the optomechanical resonator having a smaller dimension in a direction normal to the plane of the sensor compared with the dimensions of the said face.
