A door component has a controllable rotary damper and two connector units which can be moved relative to one another. One of the two connector units can be connected to a load-bearing construction and the other one can be connected to a movable door device of a vehicle, in order to damp a movement of the door device between a closed position and an open position in a controlled manner. Two mutually engaged spindle units are arranged between the two connector units, one spindle unit being a threaded spindle and the other being a spindle nut. A first spindle unit is fastened rotatably on a coupling rod connected to one of the connector units. A magnetorheological transmission device is arranged between the coupling rod and the first spindle unit, in order to brake a rotational movement of the first spindle unit as required.

A compact hinge includes two body attachments, each body attachment having a torque transfer post. A compressive friction sleeve includes a first torque transfer sleeve and a second torque transfer sleeve. A first torque transfer post is inserted into the first torque transfer sleeve and a second torque transfer post is inserted into the second torque transfer sleeve. A gear set causes the first torque transfer post to rotate with the same rotational angle as the second torque transfer post.

Included are: a main body including an installation part in which a cartridge housing a liquid for treating a test substance contained in a specimen is installed and a detector configured to detect the test substance treated with the liquid within the cartridge installed in the installation part; a lid part arranged rotatably on the main body about a shaft so as to open and close the installation part; a biasing part biasing the lid part in an opening direction; and a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part.

A hinge includes a hinge arm, a hinge cup, at least one resilient member, and a retaining member. The hinge cup is pivotally connected with respect to the hinge arm and includes a receiving room. The resilient member is mounted in the receiving room of the hinge cup. The retaining member is mounted at the resilient member.

A device has at least two components which are movable relative to one another. The first component is equipped with a rotary receptacle and wherein the second component is rotatably received on the rotary receptacle. A third component is coupled to the second component. Two connection units which are movable relative to one another and a controllable braking device are included, wherein the braking device is designed as a controllable rotary brake in order to provide controlled damping of a movement of a door device between a closed position and an open position. The first connection unit is formed on the first component, and the second connection unit is pivotably coupled to the third component. The pivot axis is oriented transversely with respect to an axis of rotation of the second component.

A hinge assembly including a hinge cup, a hinge arm and a hinge lever pivotally connected to both the hinge cup and the hinge arm so as to connect the two together. The assembly further including a damping device and an actuator assembly operable to activate the damping device as the hinge assembly moves from an open position to a closed position. The actuator assembly is operable to move from a second position to a first position to actuate the damping device, where the hinge arm engages with the actuator assembly to cause said movement from the second position to the first position.

A valve mechanism according to certain embodiments includes an adjustment screw and a rotatable control knob coupled with the adjustment screw. The valve mechanism includes a feedback mechanism operable to provide at least one of visual feedback, audible feedback, or tactile feedback to indicate movement and/or a positon of the adjustment screw within a door closer body.

A hinge structure connected between two bodies of an electronic device is provided. The bodies are rotated to be folded or unfolded relatively through the hinge structure. The hinge structure includes a first rotating shaft, a second rotating shaft, and a torsion member that the first and the second rotating shafts being pivoted thereto, such that the torsion member surrounds and grasps an axial surface of the first rotating shaft and an axial surface of the second rotating shaft respectively. The first rotating shaft has a first actuating portion and a second actuating portion. The second rotating shaft has a third actuating portion and a fourth actuating portion. The torsion member has a first torsion providing portion located on a moving path of the first and the second actuating portions and a second torsion providing portion located on a moving path of the third and the fourth actuating portions.

A hinge for articulatedly connecting first and second components, with first and second hinge parts for fastening to the first and second components, respectively, with a first pivot arm which comprises a first articulation axis on the first hinge part and a second articulation axis on the second hinge part, wherein the first hinge part comprises a longitudinal guide for the first articulation axis of the first pivot arm, and with a second pivot arm which comprises a first articulation axis on the first hinge part and a second articulation axis on the second hinge part, wherein the first hinge part comprises a damping element, wherein the first pivot arm is connected to a braking element, wherein a setting element is provided which comprises a pressing part, which acts on the damping element, and an actuating part, wherein the actuating part is in an access hole of the first hinge part.

A compartment damper assembly that is configured to vary force on a moveable member of a compartment. The compartment damper assembly includes a housing with an interior chamber. The compartment damper assembly also includes an air regulator system within the interior chamber of the housing. The air regulator system includes a piston movably disposed within the interior chamber of the housing, wherein a first chamber section and second chamber section are formed within the interior chamber, a piston support extending through the piston and including a variable depth slot to allow air to pass between the first chamber section and second chamber section to vary a vacuum force on the piston, and a spring element engaging the piston and the piston support to place a spring force between the piston and piston support.
