A link structure (1) includes: a first link (2); a target member to be moved (housing) (3) that is provided in the interior of the first link (2), and that is movable in the interior of the first link (2); a movement mechanism (4) that is fixed to the first link (2), and that is configured to cause the target member to be moved (3) to move in movement directions (M1, M2) along the first link (2) in response to power of a power part; and an action part (6) that is provided to the target member to be moved (3), and that is configured to act on a movement of a second link (8) mounted onto the first link (2).

The present disclosure involves a belt drive mechanism which can be used to pay out or draw belt to or from a belt actuated system (or belt driven system). The mechanism features a self-winding spool which can automatically wind or unwind portions of the belt as they are withdrawn from, or fed to the belt actuated system. A second rotational axle (idler shaft), with one or more sheaves (e.g., pulley's or rollers) can be rotationally coupled to a capstan via a belt, and can be utilized to drive additional mechanisms in the belt drive mechanism, such as a winding mechanism.

A drive system (46) for a telescoping boom (22) includes an elongated member (48), a locking head (50) configured to be driven on the elongated member, an actuator (52) configured to drive the locking head on the elongated member, and a cabling assembly (54) interconnected between the actuator and the locking head such that the locking head is driven on the elongated member in response to operation of the actuator, the cabling assembly including a cable (64) and a plurality of sheaves (66, 68). The telescoping boom includes a base section (34) and one or more telescoping sections (36, 38, 40) configured for telescoping movement relative to the base section, and the locking head is configured to selectively engage and disengage a telescoping section of the one or more telescoping sections.

An upper torso augmentation device in which a moment of an arm assembly is tunable by the movement of one or more movable masses. The upper torso augmentation device including an upper arm assembly pivotably coupled to a shoulder assembly, the upper arm assembly including an assisted force mechanism configured to aid in counteracting an effect of gravity upon the upper arm assembly and any payload carried thereby, the assisted force mechanism comprises one or more movable masses configured to move relative to a distal end of the upper arm assembly, thereby affecting a change in a moment of the upper arm assembly.

In one embodiment, a rotor is coupled to the support such that the rotor can rotate about an axis of rotation relative to the support. The rotor has a first surface for supporting a piece of flexible material at a diameter D about the axis of rotation. The carriage is coupled to the support such that the carriage is constrained to slide parallel to the axis of rotation of the rotor. A second plurality of pulleys comprises a third pulley, a fourth pulley, and a fifth pulley. The piece of flexible material is coupled to the rotor, then helically wound around the first surface of the rotor with a lead l, then wrapped around the third pulley, then wrapped around the first pulley, then wrapped around the fourth pulley, then wrapped around the second pulley, then wrapped around the fifth pulley, then coupled to the support.

The disclosure provides apparatuses, systems, and methods for belt driven linear actuator systems.

A window shade includes a top box, a mediate bar, a bottom bar and a shade connected between the mediate bar and the bottom bar. A first scrolling unit and a second scrolling unit are located in the top box, and each are cooperated with a movable unit, a resilient member and a fixed member. The resilient member is connected between the movable unit and the fixed member. Each of the first scrolling unit and the second scrolling unit has a first roller and a second roller, and each of the movable unit has a third roller and a fourth roller. The first cords of the first scrolling unit are connected to the mediate bar. The second cords of the second scrolling unit extend through the mediate bar and are connected to the bottom bar. The first and second cords meet the requirements of a longer shade.

Disclosed herein are methods, systems, and components for the design of a flat belt based block and tackle design that is theoretically free of fleet angles. A mapping technique forms a set of planar positions for the centerlines of the free spans that provides a plurality of sheave geometries, which reside on a common axis and spans that are free of fleet angles at the sheave engagement interfaces. This permits the use of high-performing flat belts in high-reduction block and tackle topologies, with the principal benefits of an extended service life, high power transmission efficiency, more effective traction power transfer, and a compact machine design.
