Abstract: For remotely operated vehicles (ROV) deployed subsea, communications between an ROV and a system remote from the ROV may use a remotely operated vehicle control communication system to achieve simultaneous and/or discrete data communications at two differing data transmission speeds using two differing data protocols over a common signal transmission pathway configured for use subsea at the first data transmission speed and the second data transmission speed, either separately or concurrently.

Abstract: The disclosed couplers operate in a “near field” mode, meaning energy, whether used to transmit data or power, is transferred through magnetic induction using a ?i/?t circuit (meaning a change in current over a change in time), such as by using inductive transmission and receive coils in which resistors and/or other components such as diodes are placed into series and/or in parallel with the coils and used to control the shape of the pulse, e.g. its voltage and/or frequency. In embodiments, the connectors are use to couple a power source to a power receptor.

Abstract: A programmable fuse system provides under-voltage/short-circuit protection, and comprises an electrical circuit sensor operatively in communication with a predetermined set of electrical circuits; a controller operatively in communication with the electrical circuit sensor, the controller comprising active logic, memory, and data representing a set of characteristic current/trip time curves; and one or more programmable fuses operative to completely disconnect a predetermined electrical circuit of the set of electrical circuits on detection of a fault, without the need to replace a programmable fuse and without reliance on any small current to maintain its protection, and to remain completely disconnected until commanded to turn back on.

In an embodiment, one connector comprises a voltage comparator which comprises a hysteresis circuit adapted to be centered at a predetermined no pulse voltage for use in data transmission.
