    Abstract: A torque transfer device has plural planets arranged for planetary rotation about one or more sun gears and within one or more ring gears. Each planet includes at least one planetary gear set comprising plural planetary gears connected to rotate together, but having a different diameter to form a differential gear system. To improve load sharing, the plural planetary gears of each planetary gear set may have a different helical angle, the plural planetary gear sets being axially movable with respect to one another. Alternatively or in addition, the planetary gears may be made flexible with respect to radial forces.

    Abstract: A high speed ratio drive system is formed of planet rollers, each having varying diameter, an outer fixed ring in contact with one diameter of the planet rollers, and an outer drive ring in contact with another diameter of the planet rollers. An inner drive element is provided by a sun drive roller in contact with the planet rollers or by a planet carrier. Preferably the system has an axial reflective symmetry minimizing twisting forces on the planet rollers.

    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: An exercise device is provided using, for example, handles, connected to cords that increase in tension as the handles are pulled. The tension may be provided using elasticity of the cords or by an actuator, for example powered by an electric motor. Pulleys allow adequate extension while remaining compact enough to fit in a standard height room and allowing accessibility to components. Upper and forward pulleys may be used. The upper pulleys may be displaced from potential obstacles, including the forward pulleys.

    Abstract: A pulley system comprising: a first pulley rotatable about a first pulley axis, a first cable portion wrapped around the first pulley, such that, when the first pulley is rotated in a first direction about the first pulley axis, the first cable portion is unwound from the first pulley, and a second cable portion wrapped around the first pulley, such that, when the first pulley is rotated in the first direction about the first pulley axis, the second cable portion is wound further onto the first pulley, wherein the first and second cable portions form a continuous cable passing radially through the first pulley.
