A method for stabilizing a loose showerhead assembly and a shower stabilizer assembly are provided. The showerhead stabilizer assembly includes a stabilizer plate, one or more spacers of varying sizes/thicknesses, and a plurality of fasteners to secure the stabilizer plate to a structure. The method for stabilizing a loose showerhead includes the steps of removing the showerhead, installing one or more spacers onto the shower arm pipe to a depth that creates a hard stop, installing the stabilizer plate such that a spacer contact nipple of the stabilizer plate creates a hard stop against the spacer and the circular flange is in contact with the front surface of the shower wall, and securing the stabilizer plate by installing one or more fasteners in appropriate mounting holes located in the flange.

A method for emitting a fluid from an aerial fluid dispersal system includes emitting the fluid from a plurality of individually controlled nozzle assemblies distributed across a manifold assembly. The method also includes receiving, at a controller, an input associated with a desired droplet size of the fluid emitted from each respective nozzle assembly and determining, by the controller, a target differential fluid velocity for each respective nozzle assembly based on the desired droplet size. The method also includes regulating, using the controller, the velocity of the fluid exiting each respective nozzle assembly to produce the target differential fluid velocity from each respective nozzle assembly.

A hose assembly includes a first conduit, a second conduit, a nozzle assembly, and a valve assembly. The first conduit defines a first fluid path through the hose assembly. The second conduit is received within and extends partially through the first conduit. The second conduit defines a second fluid path through the hose assembly. The nozzle assembly is coupled to a first end of the first conduit. The valve assembly is fluidly coupled to the first conduit and the second conduit. The valve assembly is fluid coupled to a second end of the first conduit opposite the first end. The valve assembly is adjustable between a first position and a second position. In the first position, the valve assembly provides water into the first conduit. In the second position, the valve assembly provides pressurized air into the second conduit.

A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.
