A parking pawl module includes a first actuator, a gearbox including at least one gear carrier where the at least one gear carrier supports a hub configured to rotate when the first actuator rotates, and a disconnect module. The disconnect module includes: an output coupler having a first surface and a second surface; an actuation feature disposed on the first surface; and a torsion spring having a first end connected to the output coupler and a second end connected to the hub or the at least one gear carrier. The disconnect module also includes an actuation mechanism disposed on the second surface of the output coupler. The actuation mechanism is configured to mesh with the hub. The first actuator controls movement of the at least one hub, the actuation feature, and the actuation mechanism.

An actuator for adjusting a seat includes a motor, a gear-box, and an output member. The gear-box includes a casing accommodating a two stage gear train connecting the motor to the output member. The gear train has a first and second transmission mechanisms. The first transmission mechanism includes a worm on a shaft of the motor, and a worm wheel meshed with the worm. The second transmission mechanism is a movable teeth gear transmission mechanism and has an eccentric wheel that rotates with the worm wheel, an internally toothed ring gear fixed to the casing, a fluted disc with radial grooves formed in its outer periphery, and rollers mounted in the radial grooves. The eccentric wheel drives the rollers to mesh with the ring gear to rotate the fluted disc, to drive the output member.

A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

A shutter device for a front grille of a vehicle including a structure and at least two flaps coupled in a pivoting manner to the structure. An actuator and a transmission mechanism coupled to the actuator are configured to transmit the movement of the actuator to the flaps to carry out a sequential opening of the at least two flaps. According to one embodiment the transmission mechanism includes one gear for each of the at least two flaps, each gear comprising a drive wheel coupled to the actuator and a driven wheel coupled to the respective at least two flaps. Each of the drive wheels and driven wheels includes a notched part and a blocking part that are distributed differently to cause a sequential opening and/or closing of the at least two flaps.

The present disclosure relates to a variable valve drive for a lifting valve, in particular for a charge-exchange valve of an internal combustion engine, which is periodically movable between a closed position and an open position indirectly by way of a cam via a rocker lever. The variable valve drive includes a switchable rocker lever arrangement for the actuation of the lifting valve, having a transmission rocker lever and a valve rocker lever which are mounted pivotably on different rocker lever axles which are each parallel to the camshaft axis.

The present invention relates to a twisted string actuator. The present invention may comprise: a drive source; driving parts for receiving power from the driving source; driven parts installed in conjunction with the driving parts and receiving power; strings coupled to the ends of the driving parts and the driven parts so as to be twisted or untwisted, and a driving compensation part installed at the ends of the strings to compensate for uneven actuation of each of the strings.

A derailleur includes a fixed component, a movable component, a linkage component, a deceleration component and a drive component. The fixed component is for being fixed to a bicycle frame. The movable component is for being fixed to a chain guide. The linkage component includes a first linkage and a second linkage. Two ends of the first linkage pivot on the fixed component and the movable component, respectively. Two ends of the second linkage pivot on the fixed component and the movable component, respectively. The deceleration component includes a circular spline, a flex spline and a wave generator. The flex spline is disposed inside the circular spline, for rotating the first linkage and the second linkage relative to the fixed component. The wave generator is disposed inside the flex spline. The drive component is connected to the wave generator, for rotating the wave generator.
