A regenerative drive system for generating a rotary movement, which is in the form of a direct hub drive and includes an electric machine that works on the piezoelectric principle, more particularly in the form of a swash plate motor is provided. The drive system can be fitted in vehicles such as box trucks, truck tractors and trailer vehicles.

A mechanical virtual elliptical drive, including an input motor, a wobble plate, a stator gear, and an output plate. The input motor may have a rotation axis, a substantially flat surface, and a rounded protrusion extending from the flat surface. The wobble plate may have a wobble axis disposed at a non-zero angle relative to the rotation axis. The rounded protrusion of the motor may engage a substantially flat face of the wobble plate, thereby causing the wobble plate to nutate around the stator gear.

A swash plate includes 34.5 to 43.0 wt % of copper (Cu) and 0.5 to 2.8 wt % of silicon (Si), with a remainder of aluminum (Al) and other inevitable impurities.

An intermeshing rotary-wing aircraft comprises a first rotary blade portion including a first blade and a second blade, a second rotary blade portion including a third blade and a fourth blade, a first shaft and a second shaft that transmit power to the first rotary portion and the second rotary portion and are symmetrically positioned at a predetermined angle, a first swash plate portion for controlling the first blade and the second blade, and a second swash plate portion for controlling the third blade and the fourth blade, wherein the first swash plate is coupled to three linkages, in which the coupled positions are located at the vertices of an equilateral triangle, the second swash plate has the same shape as the first swash plate, and the two equilateral triangles of the first swash plate and the second swash plate are star-shaped when horizontally moved and overlapped.

A massage mechanism and its massager. The massage mechanism includes a base, motor, drive assembly, first drive shaft, first bearing, first massage drive assembly, first massage head assembly, inter-shaft drive assembly, second transmission shaft, second bearing, second massage drive assembly and second massage head. There is also provided a massager including the foregoing massage mechanism. The mechanism could optimize those unstable and noisy features for an ideal massage experience, and solve the problem that multiple massage actions cannot be driven by a single motor.
