  • Underwater displacement probe
    Patent number: 4140991
    Abstract: This device is used in an underwater environment to determine the exact ltion of an object or the displacement of an object from an equilibrium position within a relatively small confined area. An alternating electric current is transmitted through the water, thereby creating an electric field surrounding the object. A probe placed on the object and connected to a voltage amplifier measures the electric potential of the probe and the object with respect to the potential of one of the electrodes. The position or the displacement of the object is then determined from its measured electric potential.
