ABSTRACT:
The detection of brief pulses generating high frequencies is carried out by a system including: sensor for detecting an electrostatic field and for detecting an electromagnetic field, such that the variation of the electrostatic field ocurring in a period of time of less than 1 millisecond may be identified. A signal activator for warning about the presence, in an interval of time of less than 1 millisecond, of the variation of the electrostatic field detected and of the electromagnetic field, allowing identification of a pulse due to an electrostatic discharge from furniture or human beings. The invention is applicable to the detection of pulses due to electrostatic discharges.
