An embodiment of the present invention includes an advanced adjustable density misting delivery system (AMDS) for detecting and neutralizing a fire. The AMDS includes a bladder containing a fire suppressant material, a pump operatively connected to the bladder via a tube, and a nozzle operatively connected to the pump and the bladder via the tube. The AMDS also includes a controller electrically connected to the pump and a sensor in communication with the controller, where the sensor is configured to detect a parameter that indicates the presence of the fire. The controller is configured to transition the pump from a deactivated state to an activated state when the sensor detects the parameter, such that in the deactivated state the pump does not operate, and in the activated state the pump causes the fire suppressant to flow from the bladder, through the tube, and out the nozzle.

A controlled droplet applicator (CDA) system comprising a CDA nozzle cup having an open end; a shroud covering all but a portion of the open end; and an air assist device disposed proximal to the open end, the cup and the air assist device separated by at least a portion of the shroud.

A method of atomizing a fluid using a pair of counter-rotating rollers including a first roller having grooves, the grooves enclosed by a pair of fins extending away from the first surface and a second roller having channels, the first and second rollers aligned with each other such that the grooves of the first roller mate with the channels of the second roller forming enclosures and nips. The method includes drawing the fluid from a fluid source through the nips, the nips having an upstream side and a downstream side, stretching the fluid between the diverging surfaces of the pair of counter-rotating rollers on the downstream side of the nips to form fluid filaments, and forming fluid droplets from the stretched fluid filaments on the downstream side of the nips between the diverging surfaces of the pair of counter-rotating rollers.

An atomization device for forming liquid particles is provided. The device includes a brush having a plurality of filaments coupled on one end thereof to the brush such that an opposing end of the filaments is free to oscillate; a plate having at least one liquid path configured for capillary action of liquid therein; wherein the brush is configured to be displaced with respect to the plate in a first direction during a cyclic displacement; and wherein disposition of the plate with respect to the brush is such that during the displacement in the first direction the filaments are displaced between a first position in which the opposing end is engaged with an edge of the liquid path collecting thereby film of liquid therefrom, and a second position in which the opposing end is free to oscillate in an alternating motion between the first direction and a second opposing direction.

A controlled droplet application (CDA) nozzle has a CDA nozzle cone having a first axis of rotation in a first position and, after adjustment, a second axis of rotation in a second position orthogonal to the first. A rotationally adjustable directional shroud surrounds at least a portion of the cone, the directional shroud blocking at least a portion of a lip of the cone regardless of whether the cone is positioned in the first or second axis of rotation.

An atomization device including a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments breaking into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device, the baffle fluid transporting formed droplets of the feed fluid from the atomization device. Excess or misguides atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.
