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.

Operating a fire control system is described herein. One method includes receiving, at a gateway device, first operational data of a first format from a control panel, determining a model associated with the control panel based on the first operational data, wherein the model includes correlations between the first operational data and alarm information of a second format, receiving second operational data of the first format from the control panel, and determining alarm information of the second format associated with the second operational data based on the model.

A fire detection device and method therefor are able to provide automatic activation so as to extinguish a fire. The fire detection can be rapid and temperature-based. In one embodiment, a heat collector can be provided to enhance thermal responsiveness. Activation of the fire detection device can be electrically or mechanically induced to release an extinguishing agent at the fire. The activation can be protected such that it is durable and unaffected by vibrations.

A controller for a motor vehicle having an internal combustion engine, and a device for detecting a fire in a fluid conduit, the device having a fluid state sensor for detecting a state variable of a fluid that is conducted in the fluid conduit, are provided. The determination of a fire situation is performed in a manner dependent on a signal of the fluid state sensor.

A fire extinguishing system includes a gas discharger provided at a battery pack and configured to discharge gas in the battery pack, a gas channel configured so that the gas produced from the battery pack and discharged through the gas discharger flows through the gas channel when a fire occurs, an extinguishing agent tank in which an extinguishing agent is kept, a heat exchange channel provided in the extinguishing agent tank, connected to the gas channel so that the gas supplied through the gas channel flows through the heat exchange channel, and facilitating heat exchange between the gas flowing through the heat exchange channel and the extinguishing agent kept in the extinguishing agent tank, and a nozzle provided at the battery pack, connected to the extinguishing agent tank through an extinguishing agent supply channel, and supplying the extinguishing agent, which is supplied from the extinguishing agent tank, into the battery pack.

An aircraft includes an airframe defining a first enclosed space, an engine bay disposed within the first enclosed space, and a cooling system. The engine bay includes a firebox defining a second enclosed space and an engine disposed at least partially within the second enclosed space. The cooling system is configured to selectively fluidly couple the first enclosed space with the second enclosed space.

A fire suppression system includes a motor and a foam pump. The foam pump is driven by the motor to inject one or more chemical additives from an off-board additive container into a discharge conduit. A bypass valve is in fluid communication with the output of the foam pump. One or more sensors are configured to measure at least one operating condition of the foam pump. A controller is in communication with the one or more sensors and is operatively connected to the bypass valve. The controller is configured to determine, based on data received from the one or more sensors regarding the at least one operating condition of the foam pump, whether the foam pump is experiencing a loss of prime, and to open the bypass valve in response. The motor may also selectively operate in one of two modes depending on the rotational speed and torque required.

The present invention relates to methods and apparatus for detection of fire states in the presence of welding activities. In some examples, the welding detection system may algorithmically calculate a risk of a fire state developing. In some embodiments, the welding fire detection and prevention system may communicate warning states to users, supervisors, equipment and/or building monitoring systems.
