A head mechanism includes a base connectable to a body of a robot, a mounting member arranged above the base, a connecting member rotatably connected to the base and the mounting member. The connecting member, together with the mounting member, is rotatable relative to the base about a first axis, and the mounting member is rotatable relative to the connecting member about a second axis. The first axis and the second axis extend in different directions. The head mechanism further includes two first actuating mechanisms fixed to the base, and the two first actuating mechanisms are configured to drive the mounting member to rotate with respect to the base.

The invention is directed towards a device for adjusting the height or the distance or the inclination of an object in relation to a structure to which the object is displaceably or pivotably connected, in particular for adjusting the inclination of a backrest of a pushchair in relation to the chassis thereof, comprising a pulling means which has at least one length-adjustable strand which is connected in the region of one of its ends to the structure and in the region of its other end to the object.

A link actuation device includes: a parallel link mechanism including a proximal-side link hub, a distal-side link hub, and three or more link mechanisms coupling the distal-side link hub to the proximal-side link hub such that a posture of the distal-side link hub can be changed with respect to the proximal-side link hub; actuators for changing the posture; and a teaching unit including a conversion unit configured to calculate coordinates (Wt (=Xt, Yt, Zt)) of a distal-side link center of the distal-side link hub, which are expressed in orthogonal coordinates, from rotation angles (βn; n=1, 2, . . . ) of the end link members. A normal vector is applied to equations of a plane and of a sphere, and the equations are rearranged and used in the conversion unit.

Flap actuation systems for aircraft are described herein. An example flap actuation system includes a fixed beam coupled to and extending downward from a fixed wing portion of an aircraft wing and a rocking lever plate pivotably coupled to the fixed beam. The rocking lever plate is coupled to a forward end of a flap bracket disposed on a bottom side of a flap of the wing. The flap actuation system also includes a crank arm, a crank rod coupled between the crank arm and the rocking lever plate, and a flap link coupled between the rocking lever plate and an aft end of the flap bracket, such that actuation of the crank arm pivots the rocking lever plate to move the flap between a stowed position and a deployed position relative to the fixed wing portion.

An exoskeleton for interfacing with a joint includes a base configured to be coupled to a user, a platform configured to be coupled to the user proximate the joint, and a plurality of substructures extending between the base and the platform. The substructures are actuated in parallel in order to move the platform.

A foldable enclosure apparatus, for a child, including an upper assembly forming an upper portion of an enclosure, and a base assembly connected to the upper assembly and forming a lower portion of the enclosure that supports a base pad. The upper assembly and base assembly are coupled by a side structure of posts, and the upper assembly, base assembly, and side structure are configured so that the foldable enclosure apparatus folds and unfolds effecting closing and opening of the foldable enclosure apparatus between closed and open positions. A flexible frame bassinet is included in the upper portion and dependent from the upper assembly. A changing platform, separate and distinct from the bassinet, is connected to the upper assembly. The changing platform is pivotally mounted to the upper assembly with mounts separate and distinct from mounting of the bassinet, the mounts include a hinged coupling and snap on clamps.
