Abstract: Light, heat, gas exchange, and water motion are all required elements to sustain aquatic photosynthetic organisms. Rather than providing separate systems, a flux of photons appropriate for photosynthetic organisms, including algae, is dispersed throughout the surrounding water. A gas source performs water movement and circulation by acting as an airlift pump while performing a liquid-gas mass transfer. Finally, heat is added to the surrounding liquid by a heat source or the light source, which increases the rate at which microorganisms grow and improve efficiencies. By combining these necessary components for aquatic life support, efficiencies are increased, costs are saved, and photosynthetic organism growth is regulated.

Abstract: An inflating pump includes an enclosure having an exterior shell and an enclosing wall located in the exterior shell and enclosing an airflow passage, and a discharge space formed between the exterior shell and the enclosing wall; an air blower connected to the enclosing wall; two air delivery pipes; and an airflow switching mechanism including a fixed seat having a plurality of chambers separately communicable with the airflow passage, the discharge space, the air blower and the two air delivery pipe, and a turnable member being turnable relative to the fixed seat for some of the chambers to communicate with one another to allow airflow pushed out from the air blower to flow through the airflow passage, the discharge space or the two air delivery pipes. Therefore, the inflating pump can inflate and deflate an inflatable air bed when the air blower constantly produces airflow in the same direction.

Abstract: A needle or stylet has a tip contour with a reverse back bevel curved toward the longitudinal axis of the needle or stylet. The needle has a flexible intermediate portion and/or a two-part construction in which a distal portion of the needle to crimped onto a proximal portion of the needle. The needle or a stylet is combined with a spring mechanism in the hub of the needle or stylet assembly. The spring mechanism positions the tip of the needle or stylet in a middle position extending from the distal end of the assembly, allows the needle or stylet to be moved into a spring loaded fully retracted configuration within the assembly as the septal wall is tented, and then releasing the spring loaded needle or stylet as the needle or stylet penetrates the septal wall. A method of using a needle or stylet with a spring mechanism is included.

Abstract: In accordance with some embodiments of the disclosed subject matter, mechanisms (which can, for example, include systems, methods, and media) for automated dietary management in healthcare facilities are provided.

Abstract: A whip system includes a base component including a first electrical connector disposed in a base housing and one or more wires coupled to the first electrical connector and routed through the base housing. The whip system further includes a collar component including a second electrical connector disposed in a collar housing and configured to electrically couple with the first electrical connector. The vehicle whip system further includes a whip component configured to couple to the one or more wires via the first electrical connector and the second electrical connector.

Abstract: An assembly and method thereof creates a stack of objects. The assembly has a diverted to move objects having a desired size from a first conveyor to a second conveyor. The diverted utilizes diversion plates. The second conveyor transfers the objects to an accumulator. The objects that are accumulate are squared and then moved to a raised position. A lift assembly then lifts the accumulated objects that were square and translates the objects to a queuing assembly. The process repeats to construct a stack of objects with multiple layers of objects. The created stack of objects may then be transferred to a subsequent destination for further use or processing.
