Abstract: In an air mobility vehicle, an engine operates as required to provide mechanical driving force or electric energy. A battery is charged with the electric energy from the engine. Main rotors operate using the electric energy of the battery and electric power generated by the engine to perform takeoff, landing, and cruising. Auxiliary rotors are disposed at or adjacent to the center of gravity of a vehicle body and mechanically connected to the engine via a clutch. The auxiliary rotors perform the takeoff, the landing, or the cruising by receiving the mechanical driving force from the engine when the clutch is in an engaged position. A controller monitors the states of the battery and the main rotors and controls the operations of the engine and the clutch.

Abstract: A roller unit for moving a slat of an aircraft wing is provided. The roller unit is adjustable in height and axial position to adjust a gap between an idle roller and a guide rail integral with the slat. The idle roller is carried by an eccentric pin having a stem portion with a threaded portion and an axially grooved end portion. A threaded annular element cooperates with the threaded portion of the stem portion to define a desired axial position of the idle roller. An anti-rotation annular element, coupled in an axially slidable manner with the grooved end portion of the stem portion, may be coupled with the threaded annular element to prevent rotation thereof on the threaded portion of the stem portion. The threaded annular element and the anti-rotation annular element are tightened together between a pair of nuts.

Abstract: The present invention is a pet training pad comprising a first end of a first conductive wire and a first end of a second conductive wire connected to a main controlling device, while a second end of the first conductive wire and a second end of the second conductive wire remain open. When a pet goes onto the pet training pad, the pet's foot makes contact with the first conductive wire and the second conductive wire at the same time, establishing an electrical circuit via the pet's foot. The main controlling device detects that the electrical circuit and then sends an electric shock current to the first conductive wire, thereby shocking the pet which will guide the pet to form a habit of not going to the position where the pet training pad is located.
