CYCLICAL SUPPLY METHOD AND DEVICE, AND DETECTION DEVICE COMPRISING SAME

摘要

The invention relates to a detection device, comprising: an electric power supply (110); a voltage regulator (115) suitable for regulating the voltage supplied by the electric power supply; at least one capacitor (120) charged by the voltage regulator; a detection circuit powered by the capacitor; and a switch (130) suitable for deactivating the regulator when the charge of the capacitor is greater than a predetermined value, such that the detection circuit is then powered exclusively by (each of) said capacitor(s). In certain embodiments of the invention, the switch is capable of opening the circuit that comprises the power supply upstream from the regulator, the switch comprises a means for comparing the electrical charge of (each of) said capacitor(s) with said predetermined value, and/or the switch comprises a transistor.
