Abstract: Systems and methods for recuperative heat exchange are described herein. Recuperative heat exchange assemblies can comprise longitudinally extending heat exchange plates defining alternating hot-side layers and cooling layers. Furthermore, water generation systems and related methods of generating water from air are disclosed herein. Water generation systems and related methods can comprise a sorption unit comprising a hygroscopic material to capture water vapor from ambient air, a thermal unit to heat the hygroscopic material and transfer water vapor released therefrom to a regeneration fluid, and a recuperative heat exchange assembly to drive condensation of water vapor from the regeneration gas to produce liquid water. Disclosed water generation systems and related methods may include a valve assembly having a slide plate movable transversely to a flow channel axis between a plurality of positions.

Abstract: Water generation systems and related methods of generating water from air are disclosed herein. In various embodiments, water generation systems and related methods comprise a solar unit or layer to convert solar radiation into heat and/or electrical energy, a sorption unit or layer comprising a hygroscopic material to capture water vapor from ambient air, a regeneration gas to accumulate water vapor from the sorption unit or layer, and a heat exchange assembly to condense water vapor from the regeneration gas to produce liquid water. Disclosed heat exchange assemblies can comprise a vapor-compression cycle or refrigeration circuit configured to circulate a refrigerant. A refrigerant evaporator can transfer heat from condensation of water vapor in the regeneration gas to the refrigerant and/or a refrigerant condenser can transfer heat from condensation of refrigerant vapor to the sorption unit or layer.

Abstract: In one embodiment, the present disclosure relates to a broach for use in a mammalian femur. The broach includes a body with a proximal portion and a distal portion extending from the proximal portion. The proximal portion has a first surface with a plurality of first teeth and the distal portion has a second surface with a plurality of second teeth. Each of the second teeth is different from each of the first teeth. And, each of the plurality of second teeth include pointed protrusions extending outward from the second surface.

Abstract: This disclosure is related to systems and methods for water treatment, storage and customization, and more particularly, to systems and related methods for water production, sanitation, adjustment, maintenance, storage and dispensing of potable water to a user. The systems and methods described herein can provide several advantages including providing consistent high-quality water at point-of-use locations, thereby avoiding inconveniences of transport, unpredictable or wasteful supply chains and/or alleviate water needs at remote locations. Furthermore, the systems and methods described herein can offer a seamless digital consumer experience with high accuracy reporting of water production, storage, quality and personalization for the user.

Abstract: The present disclosure provides a screwdriver apparatus and method of making a screwdriver apparatus. The screwdriver apparatus includes a screwdriver head and an elastomeric flank coupled to the screwdriver head. The screwdriver head includes a base portion and an apex portion. The screwdriver head is wider at the base portion than at the apex portion in a first lateral plane. The elastomeric flank is positioned at least in part along a peripheral portion of the screwdriver head between the base portion and the apex portion of the screwdriver head.
