A battery pack includes at least two battery modules arranged in one direction; and a fire extinguishing unit extinguisher having a fire extinguishing tank configured to contain a fire extinguishing agent therein, a pipe connected to the fire extinguishing tank to supply the fire extinguishing agent from the fire extinguishing tank to each of the at least two battery modules, a flow rate adjuster provided to the pipe and configured to adjust a feed flow rate of the fire extinguishing agent to be constant, and at least one valve configured to supply the fire extinguishing agent from the fire extinguishing tank to the battery module having an internal temperature rising over a predetermined temperature.

A system includes a tool and an emergency response vehicle transitionable between a motive gear and a non-motive gear. The emergency response vehicle includes a mount for removably securing the tool to the emergency response vehicle. The system further includes a scanner coupled to the emergency response vehicle and operable to detect the tool when the tool is secured to the emergency response vehicle by the mount and a controller communicatively coupled to the scanner. The system is configured to determine that the emergency response vehicle has transitioned between a non-motive gear and a motive gear and in response to determining that the emergency response vehicle has transitioned between the non-motive gear and the motive gear, cause the scanner to scan the emergency response vehicle for the tool to determine whether the tool is secured to the emergency response vehicle.

A flow control device is including a tubular body including a tubular wall with an inner surface, an outer surface, and one or more openings extending from the outer surface to the inner surface through the tubular wall; a faired body encircling the tubular body, the faired body including a radially inner surface and a radially outer surface; and a flow shield encircling the faired body, the flow shield including a radially inward surface and a radially outward surface, the radially inward surface being in a facing spaced relationship with the radially outer surface of the faired body defining a passageway therebetween, wherein the passageway is fluidly connected to the one or more openings.

A corrosion monitoring device includes a sensor assembly and a detector circuit. The sensor assembly includes at least one sensor portion disposed in an interior of a pipe in a fire sprinkler system for sensing corrosion of a wall of the pipe. The detector circuit transmits an electrical signal through the at least one sensor portion, monitors an electrical characteristic of the at least one sensor portion based on the electrical signal, compares at least one of the monitored electrical characteristic and a change in the electrical characteristic of the at least one sensor portion to at least one of a predetermined value and a previously monitored electrical characteristic, determines a corrosion status indicative of at least one of a corrosion level and a rate of corrosion of the pipe wall based on the comparison, and outputs an indication of the corrosion status.

An apparatus, operations controller and methods for controlling unmanned aerial vehicles for detection, prevention and suppression of fires in a designated zone are presented. Monitored information is received and analyzed to detect a presence of a fire event or a fire risk in the designated zone. A cargo unmanned aerial vehicle is directed to a vicinity of the fire event or the fire risk and instructed to deploy a fire retardant or a fire suppressant at a location of the fire event or the fire risk, if the presence of the fire event or the fire risk is detected.

A container holding a fire suppressing powder has a top, a cylindrical sidewall and a bottom with a hole, the bottom having a score line defining a segment. An explosive material housing containing an explosive material is mounted to a head of a mounting member. The mounting member has a lower portion smaller in cross-sectional dimension than the head, depending downward from the head and extending through the hole in the bottom. A retainer is secured around the lower portion of the mounting member below the bottom to secure the mounting member to the bottom. A fuse extends through the hole in the bottom, a passage in the mounting member, and into the explosive material housing. A plate is mounted within the container a selected distance below the top, the plate being movable a short distance toward and away from the top in response to ignition of the explosive material.

A remote-controlled powder fire extinguishing system includes a robotic mobile unit including a powder storage unit, a powder fluidization system, and a powder distribution system, the mobile unit being configured to distribute a fluidized powder onto a location affected by a fire, a remote control center, operable outside of the location affected by the fire, including a controller programmed to remotely communicate with and control the mobile unit, the powder storage unit, the powder fluidization system, and the powder distribution system, and a device configured to provide wireless connection between the mobile unit and the remote control center.

A sprinkler assembly that includes a frame having a body including an inlet, an outlet and an internal passageway extending between the inlet and the outlet to define a longitudinal sprinkler axis. Two frame arms extend distally from the body, and each arm has a portion defining a cross-sectional area with a lateral surface and a medial surface spaced about a first plane bisecting the body with the sprinkler axis disposed in the first plane. An axially aligned thermally responsive glass-bulb type trigger is disposed along the sprinkler axis. The cross-sectional areas of the frame arms are asymmetrical with respect to one another about the first plane and each cross-sectional area is asymmetric about a second plane perpendicular to the first plane. The lateral surface of each arm includes an undulation to provide the sprinkler assembly with substantially consistent thermal sensitivity about the sprinkler axis.
