A rapier loom having at least a first rapier provided between at least a first frame from a pair of frames and at least a dobby frame of a dobby machine communicable coupled with the loom, the rapier being adapted to by operatively horizontally displaced; and at least a second rapier provided between at least a second frame from a pair of frames and at least a dobby frame of a dobby machine communicably coupled with the loom, the rapier being adapted to be operatively horizontally displaced.

The present invention relates to methods, apparatuses, and systems for controlling the density of a fluid near a functional object in order to improve one or more relevant performance metrics. In certain embodiments, the present invention relates to forming a low density region near the object utilizing a directed energy deposition device to deposit energy along one or more paths in the fluid. In certain embodiments, the present invention relates to synchronizing energy deposition with one or more parameters impacting the functional performance of the object.
