Abstract: A droplet detection system includes a sensing channel, such as a microfluidic channel, configured to receive a flow of fluid that may contain one or more liquid droplets dispersed in the fluid. The cross-sectional area of the sensing channel maybe configured to allow droplets of a predetermined size to flow through the channel one at a time. A light source, a light aperture, and a light detector are positioned outside the sensing channel, which use light in a selected frequency band that has a substantially different absorbance for the liquid compared to the fluid. Liquid droplets may be detected and characterized using a signal from the light detector.

Abstract: A vent assembly having a housing (106) defining a cavity (202), a first end (102) and a second end (104), where the second end includes a coupling structure (108). The first end defines a window (110) in fluid communication with the cavity, wherein the window has a window perimeter. The vent assembly includes a vent media (206) spanning the cavity of the housing, where the vent media is breathable and forms a watertight seal to the housing at a perimeter of the vent media. The first end includes a screen structure (300) within the window perimeter of the window that can include repeating structures defining open areas.

Abstract: A hydrocarbon-in-water purification system includes a high capacity hydrocarbon absorber stage having a high capacity hydrocarbon absorber material and an inlet configured to receive a hydrocarbon-in-water dispersion from a fuel system. A polishing hydrocarbon absorber stage is in liquid communication and downstream of the high capacity hydrocarbon absorber stage including polishing activated carbon. The high capacity hydrocarbon absorber material has a greater saturation capacity than the polishing activated carbon and the polishing activated carbon has a greater polishing capacity than the high capacity hydrocarbon absorber material. A method for controlling and managing the evacuation of water from the hydrocarbon-in-water purification system includes tracking the purification state of water volumes and the bed loading states of purification beds defined in the water filter.

Abstract: A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.

Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.
