Abstract : This patent is for inductive conducting of a high-frequency signal into a cable to be detected and tracked in a seawater medium for sensing the relative position of the cable with respect to capacitor plates. The capacitor plates are positioned so that in conjunction with the cable a differential capacitor is formed. Relative movement of the capacitor plates with respect to the position of the cable is used to unbalance a Wheatstone Bridge circuit. The output signal from the bridge circuit is proportional to their displacement and is used to provide a guidance signal to realign the capacitor plates and the cable.
