Abstract: Methods and systems are provided for a multiplexed phase-separating inertial filter that is composed of helical passages that generate centrifugal separating forces. In one example, the multiplex inertial filter may include a housing with a hollow internal structure; and an array of helical passages, where each helical passage of the array of helical passages includes an open slot in a wall of the helical passage, and the open slot fluidly couples a flow path of the helical passage to the hollow internal structure of the housing.

Abstract: Methods and systems are provided for a multiphase gas/bubble diverting device. A multiphase gas/bubble diverter comprises a body with an inlet at a first end of the body and a first outlet and a second outlet at a second end of the body, opposite the first end. The multiphase gas/bubble diverter further comprises a screening element that divides an internal cavity of the body into a first sub-chamber that fluidly couples the inlet to the first outlet, and a second sub-chamber that is fluidly coupled to the second outlet. The screening element diverts all bubble and gas flow out of the multiphase gas/bubble diverter via the first outlet while diverting 100% liquid out of the multiphase gas/bubble diverter via the second outlet.

Abstract: Methods and systems are provided for a multiphase separating device comprising a superhydrophobic filter composed of at least one passage from an inlet of the multiphase separating device to a second outlet of the multiphase separating device, with a first outlet approximately midway between the inlet and the second outlet and perpendicular thereto. The superhydrophobic filter is formed of a plurality of superhydrophobic disks which are superhydrophobic on both a first face and a second face such that capillary non-wetting (e.g., gas-wicking) forces are established when the plurality of superhydrophobic disks are stacked in face-sharing contact. In one example, the at least one passage is formed as helical through holes configured to generate centrifugal separating forces.

Abstract: Methods and systems are provided for a liquid capture device, comprising a superhydrophobic expansion chamber, a user interface coupled to a first end of the superhydrophobic expansion chamber; and a collapsible bag coupled to a second end of the superhydrophobic expansion chamber, opposite the first end. The liquid capture device may be used to capture urine in reduced gravity environments.

Abstract: Methods and systems are provided for a urine capture device, comprising a first user interface having a plurality of vent holes and a collapsible bag coupled to a second end of the first user interface, the collapsible bag configured with a superhydrophilic vane structure. The urine capture device may be optionally configured with a clip-in liquid self-propelling passage, including a second user interface and a superhydrophobic passage. The first user interface may be configured for use by male users and the second user interface may be configured for use by female users, thus making the urine capture device a unisex-enabled device.

Abstract: A capillary beverage cup comprises a continuous interior corner extending from a lip interface into an inner cavity of the capillary beverage cup, the continuous interior corner comprising an acute included angle which tapers continuously as the interior corner approaches the lip interface. The capillary beverage cup provides a continuous capillary force on the liquid contained by the cup, allowing for complete withdrawal of fluid from the cup in low or near zero gravity environments, while enabling the cup to have an open top, allowing for aromatics to be experienced by a user while drinking with reduced concerns of spilling or release free-floating spheres of liquid in the low-gravity environment.
