Abstract: A smart fluid application nozzle consisting of an optical based event locating system, a multi-port nozzle block, and a port switching mechanism is disclosed by the present application. The smart nozzle utilizes a unique arrangement of discharge ports, allowing the angle of the discharge agent to be controlled without moving the nozzle housing. Multiple ports are activated per event to create a uniform fluid distribution within the discharging jet while controlling the discharge angle, which cannot be achieved through a single port discharge. Upon receiving a detection signal, the event locating system determines the spatial location of the event region and activates the appropriate discharge ports, thereby directing agent toward the event zone and applying fluid while minimizing damage to nearby areas. The use of the system may be used wherever the precise directed application of as fluid is desired including, fire suppression.

Abstract: The structure for the reduction of noise occurring when a fluid flow passes over a surface is disclosed by the present application. The structure comprises a surface with a top face that is roughly parallel to the flow wherein the face has an array of multiple separate and discreet cavities inset into the surface. Each cavity may be tuned to mitigate the noise of a specific frequency of the flow by altering the size, shape, position, angle in relation to the flow and ratios of depth, width, and length of the cavity. The cavities may be divided by partitions into sub-cavities of differing sizes, shapes and positions to mitigate noise as well. The structures may be applied to any application where a flow exists over a surface including, but not limited to, aerospace, automotive, naval and electronics. The structure may be flat, curved, tubular or any other shape subject to fluid flow.
