Discharge circuit, and use thereof in a method and in apparatus for detecting and correcting the positions of electrodes, in particular as used in apparatuses for generating pressure waves

摘要

The invention relates to an electrical discharge circuit between two electrodes. The circuit includes switch means connected in parallel between the electrodes and constituting a switch that is closed for low frequency currents and that is open for high frequency currents. The discharge circuit may be used to detect and correct the position of an electrode at will, in manner that is simple, reliable, cheap, and suitable for being automated.
