Abstract
"An electrical voltage variation detector" powered by voltage whose variations are to be detected, either directly if it is a direct voltage, or previously rectified if it is alternating, and constituted by a Wheatstone bridge formed by three ohmic resistances and a fourth resistance constituted by a semiconductor whose electrical resistance is a function of the applied temperature.
