Abstract: The present invention pertains to an apparatus designed for efficient cleaning of submerged surfaces, such as those in swimming pools, fountains, and similar aquatic features. This apparatus incorporates a unique combination of a radial flow turbine assembly, which produces a pulsating flow of fluid, and one or more nozzles that discharge a spray of the fluid. The pulsating nature of the spray offers enhanced cleaning efficacy by utilizing the kinetic energy of intermittent fluid bursts. Additionally, the housing of the apparatus is inspired by hydrodynamic principles, reducing resistance during movement in water and potentially mimicking structures seen in aquatic organisms like the hammerhead shark. This design ensures smooth navigation across varied surfaces and obstructions. Optional features such as wheels and a pole connection further augment its versatility, making it a comprehensive solution for cleaning submerged surfaces.

Abstract: The present application is directed to systems and methods for operating a measurement system. Various embodiments may comprise a measurement device and a receiving device remote from the measurement device. The measurement device may acquire data corresponding to one or more measurements, convert any analog portion of the data into a digital transmission signal, and transmit the signal. The receiving device may receive the signal, convert the signal into digital data, and display the digital data.

Abstract: A canister of pressurized medicament is removed from a metered dose inhaler actuation assembly and thereafter subjected to a cleaning firing to dislodge any material that can be built up on the interior of the canister's valve stem. During the cleaning firing, backpressure in the valve stem is reduced and/or eliminated by routing the resulting flow to atmosphere along an improved flow path. The improved flow path can be such that there are no constrictions less than about 75% of the size of the valve stem's outlet port. Thus, the backpressure experienced by the valve stem is greatly reduced versus that experienced during a normal dosing firing. As a result, the flow rate of medicament through the valve stem during the cleaning firing can be higher than during a normal dosing firing, allowing the built-up material to be dislodged during the cleaning firing.

Abstract: Novel receptor polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed. The polypeptides comprise an extracellular domain of a cell-surface receptor that is expressed in testis cells. The polypeptides may be used within methods for detecting ligands that promote the proliferation and/or differentiation of testis cells, and may also be used in the development of male-specific contraceptives and infertility treatments.
