Abstract: PROBLEM TO BE SOLVED: To provide a capacitor having a small amount of change in capacitance for the capacitor manufactured by the MEMS technique. SOLUTION: This microcomponent has a capacitive component. The capacitive component is composed by the continuous coupling of at least two capacitor elements (C1, C2, C3, and C4) that are successively connected. There are first and second plates (10) and (12) in each component. The first plate (10) is fixed to the other of the microcomponents. The second plate (12) includes a portion (19) that can deviate to the first fixed plate (10) by the effect of a control signal so that the value of the capacitance of the capacitor element C1 is changed. The control signal to the plurality of capacitor elements should be independently generated so that the entire capacitance of the capacitor is changed by independent change in the capacitance of each capacitor element.

Abstract: PROBLEM TO BE SOLVED: To provide a resonator that can adjust various characteristics such as a tuning frequency and its bandwidth over a comparatively wide range. SOLUTION: The electric resonator of this invention is a basic electric resonator (1) that is provided with a ribbon conductor (2) forming a flat loop and a conductor bridge (6) that is an arch bridging over segments (3, 4) to form a variable capacitor. Part of the bridge (6) is displaced with respect to the segments (3, 4) of the loop under the control of a control signal so as to change the capacitance of the capacitor resulting that the tuning frequency of the resonator can be revised.

Abstract: An elementary electrical resonator which includes a ribbon conductor forming a flat loop with at least one turn, the conductor having ends which form two parallel segments. The resonator further includes a conducting bridge which forms an arch straddling the two parallel segments of the ribbon conductor wherein opposing surfaces of the arch and the parallel segments form a capacitor. A part of the bridge is capable of being displaced with respect to the parallel segments under the action of a control signal so as to cause the capacitance of the capacitor and therefore the tuning frequency of the resonator to vary.

Abstract: Conducting bridges (21-23) form an arch straddling parallel segments (3,4) whose ends are formed from ribbon conductor that forms a flat loop (16) with a turn. The opposing surfaces of the arch and segments forms a capacitor. A portion of the bridge is displaced with respect to the segments of the loop, under the action of a control signal, to vary the capacitance and tuning frequency of the resonator.

Abstract: The device for data transmission comprises a coder with turbocodes, that is a turbocoder (22) containing an interleaver, a circuit (24) for puncturing the coded series which is reset at the start of each block of interleaving, a circuit (26) for elaborating symbols on the basis of data and redundancy bits (D,Y1,Y2) delivered by the turbocoder, a circuit (28) for inserting a synchronization sequence into the series of symbols and the location a relation of predetermined position with respect to the elaborated symbols, which is carried out by the use of coded bits associated with the same block of interleaving, and a modulator (30). The symbols are used for the modulation of phase and/or amplitude of the carrier of fixed frequency, by the methods of the multiple phase-shift keying (MPSK) or the quadrature amplitude modulation (QAM). The method for transmitting data comprises the following steps: the coding of data, the puncture, the elaboration of symbols, the insertion of synchronization sequence, and the transmission of symbols. The method for decoding data comprises the following steps: the calculation of a quantity representative of the probability of presence of the synchronization sequence for each group of n received symbols; the incrementing of a counter-decounter, which is initially set to zero, if the quantity exceeds a determined threshold; repeating the calculation of the quantity after the lapse of a time interval corresponding to a possible period of the synchronization sequence, and incrementing the counter-decounter if the synchronization sequence is detected, or decrementing the counter-decounter otherwise; declaring that a synchronized state is attained when the counter-decounter reaches its maximum; and resetting the counter-decounter to zero and waiting for another detection of synchronization if the counter-decounter reaches its minimum. A test of another possible period of the synchronization sequence is carried out after a determined interval without attaining the synchronized state. When the synchronized state is attained, the decoding of symbols is carried out.
