A fire suppression system includes a controller. The controller is configured to receive sensor data regarding a fire condition from a sensor. The controller is also configured to determine a fire suppression response profile based on the sensor data. The controller is also configured to selectively control a flow rate of each of multiple electronically controllable variable flow rate nozzles over time to provide a fire suppressant agent to multiple zones according to the fire suppression response profile.

A water station consisting of a large water tank or bag with a plurality of dangling appendages for lowering toward the ground. These appendages include heat sensors and sprayers, and one or more may be capable of connecting to a fire fighting truck, water tank, fire hydrants, or other pieces of equipment. One or more appendages may also include a bag containing fire-fighting safety gear or ground-based hoses for fighting fires. Cameras and other sensors provide constant feedback to the pilot of the aircraft, such as a helicopter, deploying the water station.

A wall-mountable spray head unit (11) is described. The spray head unit comprises a rotatable spray head assembly (8.sub.1, 8.sub.2; FIG. 9, 8.sub.3; FIG. 17) which comprises a spray manifold (18.sub.1, 18.sub.2; FIG. 9) rotatable about a first axis (17), a spray nozzle (19) supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane in a plane defined by the first axis and a second axis which is perpendicular to the first axis, and at least one thermal sensor (20).

A water spraying fan for firefighting. The water spraying fan includes a fan mechanism mounted onto a rotatable surface attached to a base. The fan mechanism has a plurality of fan blades connected to a power source and adapted to rotate quickly, creating a strong air flow when powered on. A cage encloses the fan blades and includes one or more circular manifolds secured to a front side and positioned concentric to the fan blade axis. The manifolds contain a plurality of nozzles that are configured to disperse a liquid, such as water. The manifolds are connected to a water source via a flow control box. When activated, water flows out of the nozzles and is carried across an extended distance via the water pressure and the strong air flow created by the fan mechanism. The water spraying fan can be rotated or tilted to achieve optimal positioning.

The present invention discloses a filter comprising a tube extending from a first end to a second end and having a bore with an internal cross-sectional area. The tube comprises an inlet with an inlet cross-sectional area which is positioned through the first end of the tube. The tube also comprises an outlet with an outlet cross-sectional area, wherein the inlet cross-sectional area is less than the outlet cross-sectional area and so debris small enough to enter the inlet will tend not to block the outlet, which is larger. The filter further comprises a plurality of further inlets, often slots, in the tube between an outside thereof and the bore. In a preferred embodiment, the first end may be tapered and especially dome shaped. This helps to direct debris towards an outside of the tube, where it is less likely to be drawn into the filter and potentially block it or a downstream component, such as a nozzle. The filter may be attached to a pipeline and a nozzle.

A valve checker system includes a valve having a valve housing with an inlet side, an outlet side, and a valve element therebetween. The valve element is selectively and repeatably rotatable between a first closed position, wherein a seal is formed between the valve element and the valve housing, thereby substantially preventing fluid flow between the inlet and outlet sides, and an open position, wherein the seal is broken such that fluid flow is permissible between the inlet and outlet sides. The valve element is also selectively and repeatably rotatable within a discrete angle in a direction toward the open position, from the first closed position into a second closed position in which the seal is maintained between the valve element and the valve housing. A controller is operatively coupled to the valve element and configured to rotate the valve element between the first and second closed positions.

A vehicle includes a floor plate defining a front and a back of the vehicle, wall sections to receive vehicle loading and transfer the vehicle loading to the floor plate, and a fluid delivery assembly supported by the floor plate. The fluid delivery assembly includes an intake manifold that resides at the back, an outlet that resides at the front, and a set of lateral conduits extending between the intake manifold and the outlet to laterally convey fluid entering the intake manifold from a fluid source to the outlet for delivery to a fluid target. Accordingly, the back may connect to the fluid source and the front may deliver the fluid thus keeping the vehicle sides and top available for other uses. Moreover, the low isolated placement of the fluid delivery assembly safeguards the fluid delivery assembly and provides a low center of gravity for vehicle stability.
