US Patent 9031733 Casualty monitoring system for autonomous vehicle

A casualty monitoring system is provided in communication with a vehicle controller and configured to monitor and shut down an undersea vehicle. The casualty monitoring processor and the vehicle controller receives, but is not limited to receiving; sensing notification by a depth cutoff switch, a battery over-temperature switch, an over-pressure switch which responds to internal pressure of the vehicle; and a watchdog timer which responds to a failing casualty monitor processor. Before the casualty monitoring processor or the vehicle controller responds to a predetermined setting from these components; casualty logic of the monitoring system will have immediately removed power to the vehicle via a start-up circuit.
