Abstract: A dual-conversion tuner firstly upconverts so as to place itself outside the receive band and then downconverts with zero intermediate frequency. A filter of the surface acoustic wave type is disposed between the two frequency transposition stages of the tuner. After baseband filtering, the signals are digitized then processed in a digital block comprising a channel decoding module. With the exception of the surface acoustic wave filter, the components are entirely embodied in integrated fashion.

Abstract: The invention relates to an accelerometer comprising a plurality of proof-masses (M1-M4) moveable along a measurement axis (AB); a respective spring (K1-K4) rigidly attached to each proof-mass, configured to exert an elastic recall on the proof-mass in the measurement axis; a fixed stop (S1-S4) associated with each proof-mass, arranged to intercept the proof-mass when the acceleration in the measurement axis increases by a step; and an electrical contact associated with each stop, configured to be closed when the associated proof-mass reaches the stop. The proof-masses are suspended in series with respect to one another by springs in the measurement axis, the stops being arranged to successively intercept the respective proof-masses for increasing thresholds of acceleration.

Abstract: An electronic circuit, comprising at least an analog part, subjected to predefined input signals in the time domain, is broken down into at least one modeled elementary block. The input signal is transformed into a simulation signal which comprises at least one useful signal component representative of the spectral power density of the input signal. Application to an input of the simulation signal circuit is simulated. The useful component of the simulated signal is computed on output of each successive block. The useful component of the simulated signal output from the circuit is compared with at least one predefined signal to test at least one characteristic of the circuit. A noise component can be introduced in a simulation signal or in the output signal of a block passed through.

Abstract: A multiposition microswitch that includes a cavity, a mobile portion made of a deformable material extending above the cavity, at least three conductive tracks extending on the cavity bottom, and a contact pad on the lower surface of the mobile part. The mobile part is capable of deforming, under the action of a stressing mechanism, from an idle position where the contact pad is distant from the conductive tracks to an on position from among several distinct on positions. The contact pad electrically connects, in each distinct on position, at least two of the at least three conductive tracks, at least one of the conductive tracks connected to the contact pad in each distinct on position being different from the conductive tracks connected to the contact pad in the other distinct on positions.

Abstract: A radio signal receiver includes an input for receiving an input signal having an input carrier frequency modulated by a payload signal to be detected. A frequency converter changes the carrier frequency of the input signal and produces an intermediate signal that is an image of the input signal, and has a carrier frequency equal to an intermediate frequency. A filter circuit filters the intermediate signal. A demodulator eliminates a component, with a frequency equal to the intermediate frequency, from the filtered intermediate frequency, and produces the payload signal. The receiver also includes a detection circuit to produce a level signal representative of a level of the payload signal. A control circuit applies a control signal representative of the level signal to a control input of the frequency converter, the filter circuit and the demodulator.
