Patent ID: 8922385

Claim:
A coupling fault detecting system, comprising: a first selectively-pressurized fluid conduit; a first communication cable disposed within the first selectively-pressurized fluid conduit and configured to transmit a communication signal; a second selectively-pressurized fluid conduit; a second communication cable disposed within the second selectively-pressurized fluid conduit and configured to transmit a communication signal; a coupling, the coupling including at least a first connector and a second connector, wherein: the first connector is connected to the first selectively-pressurized fluid conduit; the second connector is connected to the second selectively-pressurized fluid conduit; and the first and second connectors are connectable to each other and are configured to transmit a communication signal from the first communication cable to the second communication cable when the first and second connectors of the coupling are connected together; and a pressure sensor configured to detect pressure at the coupling and configured to communicate a signal indicative of the pressure at the coupling through at least one of the first communication cable and the second communication cable; and a controller configured to receive the signal and determine from the signal whether there is a fault in the connection between the first and second connectors.
