Abstract: The present disclosure generally relates, in certain embodiments, to light-based treatments. In some case, a subject having or at risk for a condition such as insomnia can be treated, e.g., with light, such as green light. Other conditions include sleep disorders such as sleep apnea and other indications. In some cases, the light that is administered to the subject may be green light, or the light may have a characteristic wavelength only in a wavelength range between 510 nm and 550 nm with a bandwidth no larger than 20 nm full-width-half-maximum. Other embodiments described herein are generally directed to systems for treating such conditions, kits for treating such conditions, or the like.

Abstract: A multi-phase separation apparatus shapes a fluid stream in a flow shaping line having a plurality of descending, vertically stacked curvilinear loops disposed along a fluid vessel vertical axis, stratifying the fluid stream into a primarily liquid component and a primarily gaseous component. At a point below plurality of loops, the primarily gaseous component is bled off from the primary liquid component. The primarily gaseous component may be introduced into a vortex cluster to further separate liquid entrained in the gaseous component, which separated liquid may then be combined back with the primarily liquid component. The vertically stacked curvilinear loops may be disposed within a fluid vessel to protect and insulate the loops or may be disposed about the exterior of the vessel. The vortex cluster system may be positioned within the vessel and may employ vortex tubes deployed along either a linear flow channel or a spiral flow channel.

Abstract: A fluid separation apparatus for removing one fluid component from another fluid component in a fluid stream includes an impeller disposed between an annular inlet chamber and a first fluid chamber having a hollow, conical trapezoidal shape with a diameter that reduces along a portion of the length of the first fluid chamber. The impeller redirects a liquid flowing in a circular swirling flow path along the wall of the inlet chamber to an outlet an inlet of the first fluid chamber disposed adjacent the central axis of the first fluid chamber. A coaxially aligned extraction pipe extends into a lighter density fluid envelope formed in the first fluid chamber adjacent the inlet of the first fluid chamber. The extraction pipe may be dynamically adjustable based on the shape of the lighter density fluid envelope to maximize removal of lighter density fluid from the lighter density fluid envelope.

Abstract: A fuel bunkering apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

Abstract: A hydraulic fracturing system utilizes a multi-phase separation apparatus to separate gas entrained in hydraulic fracturing fluids during the blending process prior to introduction of hydraulic fracturing fluid into high pressure fracturing pumps by directing hydraulic fracturing fluids from a blender through a plurality of loops and thereafter, directing a portion of the separated fluid into a vortex cluster system.

Abstract: A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters.

Abstract: A multi-phase separation flow management system includes a housing with an inlet, a first outlet and a second outlet and in which a movable element is mounted. The movable element has a first passageway with an inlet and an outlet and a second passageway having an inlet and an outlet, and are disposed in the element so that the inlets of the first and second passageways are adjacent one another and the outlets of the first and second passageways are spaced apart from one another. The inlets are disposed adjacent a housing inlet, the first passageway outlet is disposed adjacent a first housing outlet and the second passageway outlet is disposed adjacent a second housing outlet.

Abstract: A two phase gas-liquid separation apparatus is provided that shapes the flow in a flow shaping line. Shaping the two-phase flow allows centrifugal force to send the heavier, denser liquid to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow for the majority, if not all, of the gas, along with a low amount of liquid, to be sent to a conventional separator. A high ratio of vapor/liquid at a flow rate much lower than the total flow rate within the flow shaping line is sent to the conventional separator. This allows for efficient separation of the vapor from the liquid with the use of a smaller conventional separator.
