Redundant electrochemical systems and methods for vehicles are described. The systems include a first electrochemical device located at a first position on the vehicle wherein the first electrochemical device is configured to generate at least one of inert gas, oxygen, and electrical power and a second electrochemical device located at a second position on the vehicle wherein the second electrochemical device is configured to generate at least one of inert gas, oxygen, and electrical power. The first electrochemical device is configured to operate in a first mode during normal operation of the vehicle and a second mode when the second electrochemical device fails, wherein in the second mode, the first electrochemical device provides the at least one of inert gas, oxygen, and electrical power for at least one vehicle critical system of the vehicle.

A transverse hydro-laminar flow system is a system that improves laminar flow across a watercraft's hull as the watercraft is moving through a body of water. The system may include air dispersal units, a first base anchor, a second base anchor, an air supply system, a controller, and a power system. The air dispersal units enable the creation of an air layer between the watercraft's hull and the surrounding water. The first base anchor and the second base anchor facilitate the fastening of the air dispersal units about the watercraft's hull without the need to dry dock the watercraft. The air supply system provides a constant air flow to each of the air dispersal units to enable the creation of the air layer that reaches most of the watercraft's hull. The controller enables the configuration of the system, while the power system supplies the necessary power for the system operation.

A safety auxiliary system, coupled to a modular battery of an underwater vehicle having a number of modules, each provided with a plurality of cells, has: a first subsystem, which detects conditions indicative of a thermal runaway in any of the modules d manages such a thermal runaway, intervening locally on the module to cool the corresponding cells so that the thermal runaway is not propagated; and a second subsystem, cooperating with, and operatively coupled to, the first subsystem, which manages gases present in the module associated with the thermal runaway, preventing them from pouring inside the underwater vehicle. The first subsystem is provided with a first electronic control unit for each of said modules, and the second subsystem is provided with a second electronic control unit, distinct from, and operatively coupled to, the first electronic control unit through a communication connection, so as to receive an alarm signal upon detection of the conditions indicative of the thermal runaway in the corresponding module.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

An enclosure, vehicle, and method for containing an overheating device are provided. An enclosure includes a body and a door that form a volume. The body includes is connected to a Venturi tube that is in communication with a fluid flow path flowing across an opening at an opposite end. In the event an overheating device is placed in the enclosure, a pressure sensor measures a pressure in the volume and a controller opens a first valve in a flow path through the Venturi tube so that air is pumped from the volume via the Venturi effect. The first valve is closed when the measured pressure drops below a threshold pressure. The enclosure can also include an extinguishing agent that can be expelled into the volume if a temperature sensor measures a temperature above a threshold temperature.

A distributed temperature system with at least one optical fiber is provided. Each optical fiber runs horizontally and vertically within at least one compartment of a ship. Each optical fiber connects to a distributed temperature system unit or is multiplexed to a single temperature system unit. The system employs Optical Time Domain Reflectometry to support measurements of optical pulses in processing bins defined along the fiber. The spatial fidelity of the measurement capability is sufficient to localize a fire detection in individual shipboard compartments. The system can diagnosis conflagration events that produce fire and also flooding in the compartment.
