  • Patent number: 11779869
    Abstract: Methods and systems are provided for a multiplexed phase separating inertial filter that is composed of helical through holes generating centrifugal separating forces. In one example, the inertial filter may be a planar porous material with an array of helical channels, each helical channel of the array of helical channels extending from a top surface of the porous material to a bottom surface of the porous material.

  • Patent number: 9962024
    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.
