A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.

Embodiments of the disclosure include a Radio Detection and Ranging (Radar) system with reduced transmitter antenna and receiver antenna mutual coupling. The radar system includes a transmitter antenna disposed on a first side of the dielectric substrate and a receiver antenna disposed on the same side of the dielectric substrate. The radiation boundaries of the transmitter antenna and the receiver antenna are substantially parallel to a line connecting centroids of the transmitter antenna and the receiver antenna. The radar system also includes a ground plane disposed on a second side of the dielectric substrate, opposite to the first side, operatively connected to the transmitter antenna and the receiver antenna through probes. The ground plane comprises at least one groove, separating vertical projections of the transmitter antenna and the receiver antenna on the ground plane.

An air pump assembly for an inflatable product may include a housing, a cover coupled to the housing, and a rotatable assembly supported by the housing. The rotatable assembly may include a pump housing having first and second air vents, an impeller positioned within the pump housing, a motor operatively coupled to the impeller, and a rotary disc positioned between the pump housing and a vent hole of the housing. The rotatable assembly may be rotatable to a first position wherein air flows from the first air vent of the pump housing to the second air vent of the pump housing and through the vent hole in the housing into an interior of the inflatable product and a second position wherein air flows from the interior of the inflatable product through the vent hole in the housing into the first air vent and then to the second air vent.

An adjustable attachment structure for a swimming machine is disclosed. The attachment structure is configured to interact with a frame of a pool. A user may interact with a locking switch to transition the attachment structure between a locked and an unlocked state. In the unlocked state, the swimming machine may be rotated about an axis to direct a generated current in a number of directions.

An inflatable product can be inflated to a low pressure by a lower-power but high-volume electric pump, then 'firmed' or fully inflated by an auxiliary pump. The auxiliary pump may be manually powered, such that the overall cost and complexity of the electric and auxiliary pumps are still lower than a high-power electric pump. The low power high volume electric pump can be easily powered by small batteries that will also provide an increased number of inflations compared to traditional high-power pumps for a given battery capacity. Using small batteries allows the pump to be very compact in size. The auxiliary pump may work through an auxiliary air chamber within the primary air chamber and fluidly connected thereto by a check valve. The electric pump may be reversible to provide for both inflation and deflation.
