Fire extinguishing systems and methods, such as for combating compartment fires, can include or use wet and dry agents such as water droplets and aerosol-based particulate extinguisher agents. In an example, an extinguishing system includes a centralized extinguishing controller that can selectively provide the wet and dry agents to a compartment or environment. In other examples, dedicated dispenser systems separately, but optionally concurrently, provide water and aerosol-based agents to combat a compartment fire.

A system for monitoring smoke and/or temperature of an electronic device includes a fiber harness having at least one fiber optic cable terminating at a node. The node is located to measure one or more conditions at the electronic device, and a control system operably connected to the fiber harness. The control system includes a light source configured to transmit light through the fiber harness, a light sensitive device configured to receive scattered light associated with the node, and a control unit configured to analyze the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node of one or more conditions at the electronic device, wherein the control unit is further configured to transmit a signal in response to the one or more conditions, wherein the one or more conditions are one or more of smoke, fire, and temperature.

Techniques control attachment of equipment to a vehicle deck. Such techniques involve positioning an equipment base that serves as a base of the equipment on the vehicle deck. Such techniques further involve extending a latching mechanism of the equipment base to provide a first latching width that captures the equipment base between a set of deck clamps and a deck jamb mounted to the vehicle deck to fasten the equipment to the vehicle deck. Such techniques further involve contracting the latching mechanism to provide the equipment base with a second latching width that enables the equipment base to escape from the set of deck clamps and the deck jamb mounted to the vehicle deck to unfasten the equipment from the vehicle deck.

The present application discloses an automatic fire extinguishing system for an electric vehicle parking space, including a thermal runaway isolation system, and further including a detection system, a medium system, and a fire control access system. The detection system is installed inside a battery pack of an electric vehicle and performs fire monitoring inside the battery pack. One end of the fire control access system extends into a vehicle body of the electric vehicle and is joined to the inside of the battery pack, and the other end of the fire control access system extends out of the vehicle body of the electric vehicle and is communication with the medium system. The medium system is disposed outside an electric vehicle parking space. The fire control access system includes a transfer pipe and a quick insertion joint mechanism. Existing afterward fire extinguishing in the technical status in the background is resolved.

An extinguishing system and method for extinguishing fires. The extinguishing system includes-a pump system for pumping extinguishing agent; one or more nozzles connected operatively to the pump system for the purpose of spraying extinguishing agent at a source of fire; a supply or inlet arranged on the pump system for the purpose of supplying extinguishing agent to the pump system; an extinguishing conduit with an extinguishing length arranged on the pump system for the purpose of supplying extinguishing agent to the at least one nozzle; and an extinguishing controller provided with an input system for inputting system data, including data about the extinguishing conduit, the pump system and the at least one nozzle. The extinguishing controller is configured to determine with the system data an operating pressure at or close to the at least one nozzle and thereby control the pump system.

A pump intake pressure control apparatus includes an intake conduit joining a pump to either a pressurized or unpressurized liquid source, a wide-range flow controller configured to control the flow of liquid through the intake conduit, pressure sensors for detecting the pressure of the liquid in the intake conduit upstream and downstream of the flow controller, and an electronic master controller programmed to receive input from the pressure sensors and to actuate the wide-range flow controller to maintain the pressure downstream of the wide-range flow controller at or below a predetermined desired value. In one embodiment of the invention, the wide-range flow controller is a branched portion of the intake conduit having a valve in each branch. In another embodiment of the invention, the flow controller is a gate valve having a stationary triangular blocking member projecting into the passage between the inlet and outlet ports of the valve.
