An actuator for a rear view device of a vehicle, a rear view device and a vehicle with such an actuator includes a body defining a folding axis for a rear view device of a vehicle, an actuator housing being rotatably and axially displaceably borne by the body and a drive assembly being supported by the actuator housing and being configured for automatically rotating the actuator housing relative to the body about the folding axis between a first angular position and a second angular position and for axially displacing the actuator housing relative to the body along the folding axis between a first axial position and a second axial position.

A mechanism for raising and lowering an armrest for a seat includes an armrest, a rotatable hub, and an actuating linkage between the armrest and the hub, the rotatable hub having a cam that operates the actuating linkage to raise the armrest wherein the cam can rotate through a first angle of rotation where the actuating linkage is not operated a second angle of rotation where the actuating linkage is operated. The cam can rotate through a third angle of rotation where the actuating linkage is not operated, this angle being different to the first angle of rotation. The cam is torsionally linked to the rotation of a seat member.

A mechanical rotational-swinging adapter is provided to transfer a continuous rotational input from a driving tool into back-and-forth swinging output via a slotted cam structure. When the rotational-swinging adapter is installed between the nosecone and the air motor of a conventional dental handpiece, the nosecone outputs the back-and-forth swinging movement for dental work such as root canal or prophylaxis treatments.

An assembly includes a thermoelectric tripping device, a flange, and a gland. The thermoelectric tripping device is configured to be detachably coupled with a damper. The thermoelectric tripping device includes an extending arm including a fuse configured to trip at a pre-defined temperature. The flange is configured to be coupled to a surface of the damper. The gland is defined by a pair of fixtures positioned in-line with each other and having a passage configured therewithin to facilitate passage of the extending arm therethrough. A first fixture of the pair of fixtures is configured to be coupled with the flange, and a second fixture of the pair of fixtures is configured to be detachably coupled with the extending arm.

A wheel cylinder adjuster includes a rotational disc, an axle, two guiding discs and two groups of claws. An oval slot extends in a first side of the rotational disc. A flower-shaped slot extends in a second side of the rotational disc. The axle is inserted in the axial aperture of the rotational disc. The first guiding disc is connected to the axle against the first side and includes two opposite radial slots. The second guiding disc is connected to the axle against the second side and includes three radial slots. Each claw in the first group is movably inserted in one of the slots of the first guiding disc and includes an insert movably inserted in the oval slot. Each claw in the second group is movably inserted in one of the slots of the second guiding disc and includes an insert movably inserted in the flower-shaped slot.

An oscillation drive with a drive and with an eccentric coupling drive for converting a rotary motion of the drive into an oscillating rotary motion of a tool spindle about its longitudinal axis is disclosed, wherein the eccentric coupling drive has an eccentric with a first eccentricity that is driven by the drive and that works together with a coupling element that is coupled to the tool spindle in order to convert the motion of the eccentric into an oscillating rotary motion of the tool spindle, wherein the eccentric is coupled to an additional eccentric with a second eccentricity so that the eccentricities are superimposed, wherein the relative position between the eccentric and the additional eccentric is adjustable to at least two different positions in order to change the amplitude of the oscillating motions of the tool spindle.

Example landing platform systems and methods are described. In one implementation, a landing platform includes a top plate configured to support an unmanned aerial vehicle (UAV), where the top plate has a plurality of slots therethrough. A rotating plate is located adjacent the top plate and includes multiple centering pins extending therefrom and extending through the plurality of slots in the top plate. A motor is capable of rotating the rotating plate, which causes the multiple centering pins to center the UAV on the top plate.
