Abstract: Methods, apparatuses, and systems may provide for the detection of an object at a rotating intersecting plane of light created by synchronously rotating a first plane of light and a second plane of light. A first laser beam of a first color may be projected with a first laser line projector and a second laser beam of a second laser beam of a second color may be projected with a second line projector. Laser planes of the first and second laser beams may be adjusted to create a beam intersection line plane of a third color on an object located at a predetermined intersection range from the first and second laser line projectors. The first and second laser line projectors may be rotated to create a rotating plane of light of the third color on the object.

Abstract: A noise abatement system including at least one fluid circulation chamber to receive at least one flow of fluid; at least one vorticity-inducing component adjacent to the at least one fluid circulation chamber, the at least one vorticity-inducing component to redirect the at least one flow of fluid tangentially to an inside perimeter wall of the at least one fluid circulation chamber to create fluctuations in a flow and pressure of the fluid causing increased and variable vorticity within the at least one fluid circulation chamber; and at least one vorticity-interaction region in communication with the at least one vorticity-inducing component to attenuate acoustics caused by the at least one flow of fluid.
