    Abstract: A piston is arranged to move in a cylinder to define a variable volume chamber, and can expand in two directions under the influence of pressure in the variable volume chamber to provide sealing against the cylinder. The piston can comprise a primary foot and a secondary foot arranged to move relative to each other in a first direction. The primary foot and the secondary foot can each comprise plural segments arranged to move relative to each other in a second direction. The piston may be suitable for use in an inner rotor, where it forms the end of a projection of the inner rotor and fully exits and reenters the cylinders.

    Abstract: A planetary gearbox with two rows of planets, at least some of the planets including magnets. The planets are driven by a stator to drive the gearbox as a motor. The planets may be geared with axial portions with different helix angle to position the gears and avoid the need for a planet carrier or bearings. Gears with small heights and/or high pressure angles may be used to avoiding or reduce negative effects of conventional gearing.

    Abstract: A two dimensional structure such as a disk or belt is shaped or distorted to form a buckling wave. At least one contact touches the wave, two contacts squeezing the wave between them providing a firmer connection. The wave is propagated along the structure by any of a variety of means including magnets or piezo actuators. This movement of the wave moves the contacts relative to the two dimensional structure, providing a high leverage ratio.

    Abstract translation: 诸如盘或带的二维结构被成形或变形以形成屈曲波。 至少有一个触点接触到波形,两个触点在它们之间挤压波形,提供更坚固的连接。 波通过包括磁体或压电致动器的各种装置中的任何一种沿结构传播。 波的这种移动使触点相对于二维结构移动,提供高的杠杆比。

    Abstract: A control element having a beam member divided into an actuation section and a valve section positioned on opposing sides of a pivot member, in which active control of the actuation section causes buckling of the valve section to bring the valve section from a closed state to an open state or causes relaxing of the valve section to bring the valve section from an open state to a closed state.

    Abstract translation: 控制元件具有分成位于枢轴构件的相对侧上的致动区段和阀区段的梁构件,其中致动区段的主动控制导致阀区段弯曲以使阀区段从关闭状态变为 打开状态或导致阀部分放松以使阀部分从打开状态变为关闭状态。
