An adaptive method and system for monitoring a shipping container for an environmental anomaly uses sensor-based ID nodes within the container and a command node. Sensors on each ID node generate sensor data about an environmental condition proximate the ID node as disposed within the container. Each ID node periodically broadcasts the sensor data. The command node monitors a first group of sensor data from the ID nodes over a first time period to detect an initial environmental threshold condition related to the container, then monitors a subsequent group of sensor data over a second time period under a modified monitoring parameter to detect a secondary environmental threshold condition related to the container as the anomaly. In response to detecting the secondary condition, the command node generates an alert notification and transmits the alert notification to an external transceiver to initiate a mediation response related to the anomaly.

An electronic fire sprinkler system includes a plurality of electronic fire sprinklers that each output a flow of fluid in response to receiving an activation signal, a plurality of temperature sensors that each detect a temperature and output an indication of the detected temperature, a plurality of network devices that detect a distance to at least one of the plurality of electronic fire sprinklers, and a processing circuit. The processing circuit receives a plurality of detected distances, calculates a location of each electronic fire sprinkler based on the of detected distances, determines that a fire condition is present based on the detected temperature, identifies one or more of the plurality of electronic fire sprinklers based on the calculated locations and an identifier of the temperature sensor from which the indication of the detected temperature was received, and transmits one or more activation signals to the identified electronic fire sprinklers.

A system for explosively applying a fire-fighting foam is provided. The system includes a thermoelectric generator that is attached to a battery heat source. A temperature differential across the thermoelectric generator generates an electrical current having a temperature-dependent voltage. A detonator circuit is electrically connected to the thermoelectric generator. The detonator circuit measures the voltage of the electrical current. An explosive foam applicator is communicatively connected to the detonator circuit and includes a trigger mechanism that detonates a propelling charge in response to receiving a signal from the detonator circuit when the detonator circuit determines that the electrical current corresponds to temperature that is greater than or equal to a threshold temperature. The explosive foam applicator is oriented such that detonating the propelling the charge causes the explosive foam applicator to apply a foam to the battery heat source.

A solenoid actuator with firing pin position detection is provided. The solenoid actuator includes a solenoid assembly having movable armature. The solenoid assembly is mounted to a firing pin housing which houses a firing pin. The firing pin is arranged such that the movable armature acts upon the firing pin to transition it from an unfired position to a fired position. The solenoid actuator also includes a firing pin position switch is mounted within a bore that is transverse to a bore of the firing pin housing containing the firing pin. The firing pin includes cam surface that acts upon the firing pin position switch to ultimately provide an indication of whether the firing pin is in the fired or the unfired position.

Techniques and safety devices are described for extinguishing fires within an inventory management system. A plurality of fire extinguishing devices for a plurality of containers in an inventory management system is monitored. Upon determining that a fire condition is occurring within the inventory management system, a positional information data store is queried to determine a current position of a first container within the inventory management system. Two or more containers within the inventory management system that are in close proximity to the first container are identified and one or more wireless signals are transmitted to two or more fire extinguishing devices of the plurality of fire extinguishing devices that are contained within the two or more containers, to activate the two or more first extinguishing devices. The plurality of containers is scanned using an infrared scanning device to determine whether all fire conditions within the inventory management system are extinguished.

A fire-fighting system includes a pump, a nozzle for directing fluid flow from the pump to a target area, a discharge valve controlling fluid flow between the pump and the nozzle, a sensor coupled to the nozzle, and a controller communicatively coupled to the sensor. The sensor detects movement of the nozzle and generates a signal indicative of the detected movement. The controller communicatively coupled is configured to receive the signal from the sensor, and control at least one of the discharge valve, the pump, and the nozzle based on the detected movement of the nozzle.

Methods, devices, and systems for fire control panel interface generation are described herein. In some examples, one or more embodiments include a fire control panel comprising a memory and a processor to execute instructions stored in the memory to determine, from a plurality of geographic regions, a geographic region for the control panel, determine a set of standards corresponding to the determined geographic region, and generate a fire control panel interface using the determined set of standards, and a user interface to display the fire control panel interface.

Adaptive wireless node-implemented systems and methods are described for detecting an environmental anomaly related to a shipping container and reporting a layered alert notification to an external transceiver on a transit vehicle transporting the shipping container. The system has ID nodes within the container (a portion of which being associated with objects transported in the container), a primary command node within the container, and a designated survivor command node mounted to the container. The primary command node monitors signal activity from the ID nodes, identifies the environmental anomaly based upon the signal activity, generates the alert notification (identifying a targeted mediation recipient and mediation action, and establishing a mediation response priority), and transmits the alert notification to the external transceiver to initiate a mediation response. The designated survivor command node takes over as the primary command node when unable to communicate with the primary command node.
