The present invention is directed toward an exercise machine and climbing simulator that enables its users to initiate the climbing or crawling motion whilst being rotated at different angles. This invention includes a rotatable framework and a plurality of foot spines and arm spines that are configured to support the feet and arms of a user. As the framework rotates, the user incurs exercise in maintaining contact with the plurality of foot and hand spines. Each of the foot and hand spines is decoupled from each other, that is, each of the foot and hand spines is configured with independent rotational and lateral movement. By changing the angles of rotation and the positions of the foot and hand spines, gravity is applied in different ways and therefore different muscle groups are targeted. Thus, this invention assists users in acquiring varying degrees of physical fitness and mountain climbing preparation.

Driverless movement system (1) comprising at least one driverless movement device (2) movable in an environment (4) of the driverless movement system (1), wherein the environment (4) comprises at least two sub-areas (3, 5, 6) and the movement device (2) is driverless based on a first sub-map exclusively in a first sub-area (3, 5, 6) of the environment (4), wherein at least one transfer zone (9, 13, 14, 18) is formed in the first sub-area (3, 5, 6), wherein the driverless movement device (2) is configured for a change from the first sub-area (3, 5, 6) to at least a second sub-area (3, 5, 6) of the environment (4) for a movement into the transfer zone (9, 13, 14, 18), wherein the movement system (1) is configured to move the movement device (2) in the transfer zone (9, 13, 14, 18) from the to transfer the first sub-area (3, 5, 6) into the second sub-area (3, 5, 6).

To provide a moving system capable of performing more precise movement control than before.SOLUTION: The moving system 10 includes a guide rail 20 and a moving body 30. The guide rail 20 includes the first movement restricting portion 23, the second movement restricting portion 24, and the rack 27, and the movable member 30 includes the pinion 35 that is provided on the output shaft 33 of the rotation actuator 32 and engages with the rack 27, the encoder 34 that outputs an angle signal corresponding to the rotation angle of the pinion 35, and the control unit 36 that controls the rotation actuator 32. The control part 36 executes calibration control for storing an angle signal when the movement of the movable body 30 is regulated by the first movement regulating part 23 and an angle signal when the movement of the movable body 30 is regulated by the second movement regulating part 24.SELECTED DRAWING: Figure 1

Devices for implanting inside an eye and for holding an intraocular lens (IOL) are presented; the device being operable to rotate the IOL, around an optical axis of the IOL, by absorbing energy from a remote energy source; the device comprises: a stator portion configured to be fixedly positioned inside the lens capsule of the eye; a rotor portion configured to be fixedly attached to the IOL; and a movement system operable to cause rotation of the rotor portion and the IOL, the movement system comprises a plurality of actuators and at least one interaction region associated with the plurality of actuators, the plurality of actuators comprise at least two actuators operable to cause the rotation of the rotor portion and the IOL in each of the clockwise and counterclockwise angular directions, the plurality of actuators and the at least one interaction region being aligned such that at each given moment in time, each actuator of the plurality of actuators is aligned differently with respect to the interaction region associated therewith, and is configured, when being activated by said remote energy source, to engage with the associated interaction region to cause the IOL to rotate with a different incremental rotation having either a different angular distance or a different angular direction; the device may comprise a protective shielding assembly that seals the moving parts from invading biological tissue.

The application relates to a worm wheel grinder tool rest with a double-screw rod driving system, and belongs to the technical field of mechanical machining. The tool rest comprises a guide rail and a double-screw rod driving system symmetrically arranged on the upper and lower sides of the guide rail. The upper screw rod system is a main driving system, and the lower screw rod system is a following movement system. Both the systems are equipped with servo motors, ball screw rods and grating rulers to realize full closed-loop control. The application solves the problems of the traditional single-screw rod tool rest, such as large thickness, difficult maintenance, unbalanced load swing and fast screw rod wear. The upper and lower screw rods and the center of the grinding wheel are equidistantly arranged, force symmetry is ensured, unbalanced load is eliminated, and rigidity is improved. The double-screw rod driving system compares the position difference in real time and automatically compensates the screw rod clearance, and the service life of the screw rod is prolonged. The double-screw rod driving system is an independent detachable structure, and is convenient for assembly and maintenance.
