A window blind includes a fixed rail and a plurality of slats hang below the fixed rail through a ladder tape. The slats are controlled by an output adjustment mechanism to change between a first state and a second state. In addition, an output clutch mechanism is provided to collect or to expand the window blind. Said output adjustment mechanism and said output clutch mechanism are both controlled by an input mechanism. Whereby, it requires only one single control module to adjust shielding of the slat assembly composed of the slats, and to expand or collect the slat assembly.

A gear device for a clutch contains: a drive gear, a first clutching member, and a second clutching member. The drive gear includes multiple first actuation protrusions and multiple second actuation protrusions, wherein each of the multiple first actuation protrusions has a beveled face and a flat top face, and each of the multiple second actuation protrusions has a beveled face and a flat top face. The first clutching member includes multiple third actuation protrusions, each of the multiple third actuation protrusions has a beveled face and a flat top face, and the first clutching member includes a first positioning disc and a first resilient element. The second clutching member includes multiple fourth actuation protrusions, each of the multiple fourth actuation protrusions has a beveled face and a flat top face, and the second clutching member includes a second positioning disc and a second resilient element.

A drive transmission device disclosed. The device has an input gear configured to rotate by a driving force from a driving source; a swing gear configured to rotate by a driving force from the input gear, the swing gear being located at a first position when the input gear is rotated in a forward direction and located at a second position that is different from the first position when the input gear is rotated in a backward direction that is a direction opposite to the forward direction; an output gear configured to separate from the swing gear when the swing gear is located at the first position, and that is in contact with the swing gear to be rotated by rotation of the swing gear when the swing gear is located at the second position; and a shaft portion configured to support the swing gear such that the swing gear is movable between the first position and the second position. The swing gear has a guide hole into which the shaft portion is inserted.

A drive clutch having an engine braking feature for a continuously variable transmission is provided. The drive clutch includes a post that is coupled to an output of an engine. A fixed sheave, coupled to the post, has a fixed sheave belt engagement face. A movable sheave assembly that includes a movable sheave belt engaging face, is configured to move axially on the post to move the movable sheave belt engaging face in relation to the fixed sheave belt engaging face depending on a rotational speed of the drive clutch. An idler bearing is mounted on the post at least in part between the movable sheave belt engaging face and the fixed sheave belt engaging face. The idler bearing includes a one-way rotational assembly and has an outer belt engaging surface with outward extending cogs configured to engage teeth of a belt to prevent slippage during engine braking.

A system and apparatus for applying torque includes a power source that rotates an eccentric, which oscillates a torque head to cyclically drive a pawl into a ratchet wheel to provide torque to a component where the applied torque is greater than the received torque. The applied torque is offset from and parallel to the received torque. The torque is hydraulically powered and can be adjusted to run in both directions.

An incremental deployment device is provided. The incremental deployment device may include a first member with a slotted track having alternating deployment and braking segments, as well as a second member that is movably coupled with the first member and that includes a cam follower that is configured to travel within the slotted track. The deployment segments may be configured to allow relative movement between the first member and the second member with little resistance, whereas the braking segments may be configured to permit relative movement between the first member and the second member with much greater resistance or to not permit any relative movement between the first member and the second member at all. Thus, the first member and the second member may be allowed to accelerate relative to one another within the deployment segments, and are decelerated within the braking segments.
