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 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: Sub-ambient cooling systems with condensation mitigation for use with electronic devices are disclosed. An example sub-ambient cooling assembly disclosed herein includes a heat spreader to remove heat from an electronic component. A thermal electric cooler that is to remove heat from the heat spreader. A heat exchanger to remove heat from the thermal electric cooler, where the thermal electric cooler is positioned between the heat spreader and the heat exchanger. A shroud is to at least partially surround the heat spreader and the thermal electric cooler, where the heat exchanger is to transfer heat to the shroud to increase a surface temperature of the shroud.
