ABSTRACT:
A process is provided for transmitting a signal, without material connection, through a conducting wall which may be a ship's hull, to external user apparatus.
A current supplied by a generator and whose intensity is proportional to the amplitude of the signal to be transmitted is applied between two points on the hull. The magnetic field variations generated by the passage of the current are detected by a sensor on the other side of the hull and, suitably amplified, are used for controlling an apparatus.
