Abstract: This disclosure provides an integrated system and method for producing purified water, hydrogen, and oxygen from contaminated water. The contaminated water may be derived from regolith-based resources on the moon, Mars, near-Earth asteroids, or other destination in outer space. The integrated system and method utilize a cold trap to receive the contaminated water in a vapor phase and selectively freeze out water from one or more volatiles. A heat source increases temperature in the cold trap to vaporize the frozen contaminated water to produce a gas stream of water vapor and volatiles. A chemical scrubber may remove one or more volatiles. The integrated system and method utilize ionomer membrane technology to separate the water vapor from remaining volatiles. The water vapor is delivered for crew use or delivered to an electrolyzer to produce hydrogen and oxygen.

Abstract: This disclosure provides a water purification system for recovery of purified water from liquid wastewater. The liquid wastewater is converted to a contaminated gas stream using a water distillation technique. The contaminated gas stream is passed through a gas phase photolytic oxidation reaction chamber. An ultraviolet (UV) source in the gas phase photolytic oxidation reaction chamber exposes the contaminated gas stream to UV radiation to remove various contaminants in the gas phase and/or biological pathogens. The gas phase photolytic oxidation reaction chamber forms a purified gas stream from the contaminated gas stream, where the purified gas stream contains water vapor and is substantially free of contaminants. In some embodiments, an ionomer membrane may be placed downstream of a source of the liquid wastewater and upstream of the gas phase photolytic oxidation reaction chamber to treat the contaminated gas stream prior to UV exposure.

Abstract: This disclosure provides water processing apparatuses, systems, and methods for recovering purified water and concentrated brine from wastewater. The water processing apparatuses, systems, and methods utilize ionomer membrane technology to separate water vapor from volatiles of a wastewater stream. The wastewater stream is evaporated into a gas stream including water vapor and volatiles of the wastewater stream in an evaporation container. The gas stream is delivered to a water separation module spatially separated from and fluidly coupled to the evaporation container. The water vapor of the gas stream is separated out in the water separation module while the volatiles are rejected. The water vapor can be collected into purified water while concentrated brine from the wastewater stream is left behind in the evaporation container.

Abstract: A regenerable antimicrobial coating with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment is disclosed. The regenerable antimicrobial coating is derived from a polymer doped with a metal derivative which has been exposed to vapor-phase hydrogen peroxide, wherein hydrogen peroxide is sequestered in or on the doped polymer.

Abstract: This invention relates to regenerable antimicrobial coatings with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment. The same coatings would also have broad utility in the consumer, industrial, and institutional markets. The coating technology is based on sequestration of hydrogen peroxide (HP) by zinc oxide binders incorporated into the coatings.

Abstract: An inverting adapter is disclosed that inverts inverted DVB-ASI signals to produce an adapted DVB-ASI signal. This adapted DVB-ASI signal may be used by any DVB-ASI device. The inverting adapter can be contained in one small package and easily connected to any of the various amplification devices that produce inverted DVB-ASI signals. Alternatively, the inverting adapter of the present invention may be integrally formed with an amplification device to automatically provide the adapted DVB-ASI signal.

Abstract: A circuit board arrangement facilitates a direct connection to a chassis mounted connector. The arrangement comprises a printed circuit board with a first signal conductor terminating at an edge of the printed circuit board. A second signal conductor is disposed adjacent to the first signal conductor and terminates at the edge. A conductive metallic spring clip has a relieved area and is formed to fit over the edge of said printed circuit board. The conductive metallic spring clip is positioned on the edge of said printed circuit board such that the relieved area straddles the first signal conductor and the conductive metallic spring clip grips the second signal conductor for coupling the second signal conductor to the chassis mounted connector.

Abstract: A pressure fluid apparatus includes first and second parts which are adapted to be secured together. A first sealing surface of the first part forms a seal with a corresponding second sealing surface of the second part. The first sealing surface includes a spigot, and the second sealing surface includes a corresponding recess adapted to receive the spigot. The inside corner where the base of the spigot meets the first sealing surface is radiussed, and the outside corner where the mouth of the recess meets the second sealing surface is correspondingly truncated, so as to accommodate the radius. On either the radiussed inside corner or the truncated outside corner, an integral projection is provided which is deformable upon assembly of the parts, to block leakage of fluid along the path defined between the two corners.

Abstract: An improved gear pump includes seal plates having lubrication channels communicating between the low pressure side of the zone where the gear teeth intermesh and the shaft bearings. Lubricant flow is directed first through one bearing on one side of the pump and then back through the other bearing on that side to the pump inlet chamber. Placement of the lubrication channels on the low pressure side of the pump where the volume between intermeshing teeth is increasing ensures that flow reversals in the bearings and lubricant aeration are avoided; and renders bearing flow rate less sensitive to pressure so that relatively large flow channels may be used in the wear plate.
