Abstract: The electromagnetic transponder has an oscillator (L1) generating a high frequency signal. There is a second passive oscillating circuit (L3,C3) at a distance from the first circuit. The second passive circuit forms a concentrator (20) of magnetic flux which is detected by a third transponder oscillating circuit (L2,C2).

Abstract: The rising fronts of the binary signals are detected by a detection circuit (30) and a measuring circuit (32) times the intervals between the rising fronts and indicates by a logical state (W) if the time is included between a maximum and minimum (Ls,Li). The entry flip-flop of a shift register (36) memorizes the state (W) and a shift signal (D) is provided by a shift circuit (34). A decoder (38) using the shift register indicates if the required frequency exists

Abstract: A terminal (40) and a transponder (10) contain a corresponding oscillating circuit (Li,Ci,24,L2,C2). An AM transmission of a signal sends a boundary-mark toward the transponder a signal (Rx) undergo a phase demodulation in the boundary-mark. The depth o modulation (tm) of the amplitude is lower than 100%. An Independent claim is included for: (a) a terminal for performing a claimed method (b) a transponder

Abstract: The transponder includes capacitor-transistor pairs (C3,K1,C4,K2) that produce an information when the transponder is close reading-writing terminal. The oscillating circuit of the transponder has a given frequency. The transmission of the information this position does not match since the frequency is higher than that of the oscillating circuit. An Independent claim is included for: (a) a system of data transmission

Abstract: The transponder is of the type having an oscillating circuit (L2,C2) in front of a rectifier circuit (13) designed to produce a continuous voltage (Va) to an electronic circuit (17). The circuit (17) includes means for emitting digital data codes. The transponder has two capacitive modulation circuits (C2,K1; C4,K2) respectively associated with each end terminal of an inductive part (L2) of the oscillating circuit. A reference terminal of each modulating circuit is connected to a reference voltage (15) of the electronic circuit supply
