Abstract: A coupled Lamb wave resonator filter includes first and second Lamb wave resonators. The first Lamb wave resonator includes a first resonant layer, and first and second electrodes on opposite sides of the first resonant layer. The second Lamb wave resonator includes a second resonant layer, and third and fourth electrodes on opposite sides of the second resonant layer. One of the sides of the first resonant layer belongs to a plane parallel to a plane corresponding to one of the sides of the second resonant layer. Both planes pass through the third and fourth electrodes of the second Lamb wave resonator. A periodic lattice acoustically couples the first and second resonant layers.

Abstract: The resonator comprises a piezoelectric layer arranged between two electrodes. An electrical heating resistor is arranged in thermal contact with at least one of the electrodes. Temporary heating of the electrode enables the material constituting the electrode to be partially evaporated, so as to thin the electrode and thus adjust the resonance frequency. Measurement of the resonance frequency in the course of evaporation enables the heating to be interrupted when the required resonance frequency is obtained. One of the electrodes can be arranged on a substrate formed by an acoustic Bragg grating. The resonator can comprise a substrate comprising a cavity whereon one of the electrodes is at least partially arranged.

Abstract: A process is disclosed to detect a water condensation risk on a surface in contact with a wet air volume, which uses the steps of (a) placing a sensitive element on the surface, which initially takes a temperature corresponding to that of the surface, (b) by means of a heating device on this sensitive element, initiating a first heating phase until a temperature higher than the surface temperature is reached, (c) by means of a cooling device having the same thermal power as the heating device, initiating a cooling phase until a temperature lower than the surface temperature is provoked on the sensitive element, and (d) a comparison is made between the ratio of the first heating phase time to the temperature rise during heating and the ratio of cooling phase time to the temperature decrease during the cooling, a noticeable difference between these two ratios indicating a significant risk of condensation on the surface.

Abstract: A Peltier effect device which detects in particular a condensation risk, includes a substrate and semiconducting bands disposed on the upper face of the substrate. The junctions connecting said bands which make up a series circuit are formed by semiconducting bands of N-type and P-type. Junctions of the same type, i.e., N-P type are situated on the central zone of the upper face of the substrate and defines a detection zone of the device. Semiconducting bands of one type are placed on one side of the upper face of the substrate and bands of the other type are placed on the other side of the upper face of the substrate. The substrate also includes at the peripheral zone of each band, except for a frontmost N-type band and a rearmost P-type band, a plated hole extending through the substrate to a lower face of the substrate and to a plating of the lower face such that a plated hole situated at an end of the P-type band is connected to a plated hole situated at an end of a next N-type band.
