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.

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.
In a rotor in rotor configuration, a pump has inward projections on an outer rotor and outward projections on an inner rotor. The outer rotor is driven and the projections mesh to create variable volume chambers. The outer rotor may be driven in both directions. In each direction, the driving part (first inward projection) of the outer rotor contacts a sealing surface on one side of an outward projection of the inner rotor, while a gap is left between a sealing surface of the other side of the outward projection and a second inward projection. The gap may have uniform width along its length in the radial direction, while in a direction parallel to the rotor axis it may be discontinuous or have variable size to create flow paths for gases.

A power conversion device has a buckled wave disk having an axis and being radially compressed between a hub and a wave ring. The buckled wave disk is buckled in the radial direction to form circumferential waves which are displaced in the axial direction and extending around the buckled wave disk with lines formed of inflection points of the circumferential waves extending between the hub and wave ring. The wave ring is outwardly radially displaced at nodes corresponding to lines formed of inflection points of the circumferential waves. A wave propagation actuator cooperates with the buckled wave disk for driving a wave and the lines formed of inflection points of the circumferential waves around the buckled wave disk. An outer ring surrounds the wave ring, the outer ring being driven by or driving the wave ring at the nodes. A method of making a wave disk is provided.

EXOSKELETON SUIT WITH HAND CONTROL TO ENABLE WALKING
An exoskeleton suit is provided that allows a user to control the legs using the arms. Preferably there is two-way feedback/control between the legs and arms causing movement of leg joints to be proportional to movement of arm joints. Haptic forces and control forces on the joints may also be proportional. The relative magnitudes of the movements and forces may be adjustable. Rotary or angular actuators may be used. A twisting actuator is also provided using a pair of bending actuators mounted side by side to provide torsional displacement of frame members. The ability to support a portion of the user's weight on the hand grips is possible while simultaneously controlling the lower body movement by applying pitch, roll and yaw movements to that hand grip.
A flex spline torque transfer device has a flex spline that is deflected in the radial direction by magnetic attraction to form a wave. The flex spline may be deflected radially inward by magnetic attraction to form a wave. The flex spline (FS) may be deflected radially inward by magnetic attraction at one or more positions equally spaced around FS ID. The attraction may be greatest at smallest radial air gap between FS and magnetic means and lowest at largest airgap. The magnetic means may or may not be actively commutated. The highest magnetic force may be determined by smallest airgap. In another statement, a torque transfer device has a flex spline that is deflected radially inward by magnetic attraction to a permanent magnet means at one or more positions equally spaced around FS ID.
