Circuit and method for checking the impedance of electrodes and for controlling the intensity of an electric stimulus
First Claim
1. A remote receiving circuit for providing and controlling an electric stimulus applied to an animal, the circuit comprising:
- an electronic switch powered by a battery in series on a primary of a high-voltage transformer and whose on/off state can be modified by control pulses to create a source of alternating current to supply the primary of the transformer;
a first electrode and a second electrode configured to be in contact with the animal and connected to the respective ends of a secondary of the transformer; and
a peak current measuring device situated between one end of the secondary of the transformer and one of the electrodes in contact with the animal, wherein a stimulus current is applied by the electrodes to the animal'"'"'s body, wherein the peak current measuring device comprises a non-linear shunt and peak detector.
