  • the evolution of the state of the output 117 as a function of the state of the first signal S1 and of the time is represented in FIG. figure 5 by an OUT curve.
  • the evolution of the output 117 of the amplifier AOP makes it possible to turn the transistor T successively, then blocking. Indeed, the output of the amplifier AOP is successively in the high state, and in this case the transistor T is passing, then in the low state, and in this case the transistor T is blocking.

It is indeed at this time that the chopping, or cutting, of the power supply 54 is triggered, since the capacitor C1 of the trigger 10 has stored enough energy to supply the trigger 10, and that it is therefore no longer necessary to charge the capacitor C1 continuously.
  • the removable module 20 takes electrical energy from the supply signal S1 globally at each pulse of the signal S1. This makes it possible to charge its capacitor C4 which supplies the second processing unit 62 and the radiocommunication module 64.
