Three controls, three variable gear assemblies, an optional hatch or variable propeller pitch, and a variable overlap generator (VO generator), as well as one or more commutator and brushless free direct current generators may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed in a plurality of embodiments useful in wind power generation and water renewable energy generators for any of tidal and ocean current or wave conditions. Two Transgear assemblies side-by-side and sharing the same central shaft may comprise a constant speed motor control, produce required constant frequency and voltage and be reduced in part count and complexity. The variable overlap generator of a marine hydrokinetic or wind power generator may be used as a low torque generator, a high power-rated generator or a control in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range. An electromotive force (EMF) embodiment generates alternating current at constant frequency and voltage in varying wind and water speed conditions.

In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

A device for controlling an electromotive linear drive configured as a furniture drive for adjusting movably mounted parts of reclining and seating furniture, consisting of at least one threaded spindle (4, 5) that can be driven via a worm gear for displacing a lifting element, and comprising a guide body (7) which is arranged in a rotationally fixed manner on the respective threaded spindle (4, 5) and on which a worm wheel (6) is rotatably mounted, a coupling sleeve (8) which is mounted in a rotationally fixed manner, but is axially displaceable on the respective guide body (7), from which the worm wheel (6) and the guide body (7) can optionally be connected or separated via a claw clutch, and in each case an actuation element which is provided for displacing the coupling sleeves (8) as well as a switching mechanism for driving the respective actuation element.

A force transmission mechanism for a teleoperated surgical instrument may include a gear, a push/pull drive element, and a connection element. The push/pull drive element may be configured to transmit force to actuate an end effector of the surgical instrument and to rotate with a shaft of the surgical instrument when the shaft is rotated by the force transmission mechanism. The connection element may operatively couple the gear and the push/pull drive element. The connection element may be configured to convert rotational movement of the gear to a substantially linear movement of the push/pull drive element. The connection element may be configured to rotate with the push/pull drive element and relative to the gear.

A robot includes a base; a trunk linked to the base; a multi-joint robot arm rotatably linked to the trunk; and an elevating mechanism capable of bringing the trunk to a low position and a high position higher than the low position, and a time taken when a tip of the multi-joint robot arm is moved by a predetermined distance when the trunk is at the high position is longer than a time taken when the tip of the multi-joint robot arm is moved by a predetermined distance when the trunk is at the low position.

Electromotive auxiliary drive, particularly a wiper drive, with an electric motor and a downstream gear forming an output shaft of the auxiliary drive, presenting at least two gear stages arranged in series in a drive train between the electric motor and the output shaft, of which one first gear stage is designed in the manner of a worm gear consisting of a worm and of a gearwheel or worm wheel interacting with this worm.

The invention relates to a device (32) for manually actuating a piece of closing or sun protection equipment (10), in particular of the blinds or rolling shutters type, including a stationary case (42) having two aligned bearings (44) defining an axis of rotation (200), a worm (34) guided in rotation in the bearings (44) and a driving rod (54) to rotate the worm (34). The worm (34) being passed through by an axial hole (52), the driving rod (54) being able to be inserted in the axial hole (52) by securing the driving rod (54) in rotation with the worm (34). A snapping connection between an elastically deformable staple (56) and a bearing shoulder (64) allows the insertion of the driving rod (54) into the axial hole (52), and blocking the removal of the driving rod (54) inserted into the axial hole (52).

A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.
