A control method includes controlling a lever, a pusher and a motor so as to arrange the same in a correct position when electric power is supplied to the home appliance, or the user turns on the home appliance. Abnormalities involving an automatic opening of the door through changes in a return/stop switch and an opening sensing switch while the motor operates so as to open the door may be confirmed.

A cam action door closer comprising a body, a spring, a speed control channel system and a latching control channel system, a closing control piston having a piston head and a circular side. The closing control piston has a cutting on the side of the closing control piston and on the piston head, the cutting forming a control edge at its end. The cutting has a length between the piston head and the control edge. The speed control channel system comprises a speed connecting channel, which is located in such a way that the control edge is arranged to close it.

A device has at least two components that can be moved relative to each other. A drive device is provided with a drive housing and a drive shaft in order to bring about a relative movement of a first component to a second component. If the drive shaft is coupled in a rotationally fixed manner to the second component, the drive housing is rotatably accommodated on one of the two components and can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom. If the drive housing is coupled in a rotationally fixed manner to the second component, the drive shaft can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom.

An appliance includes a hinge module between a main body and a pull-down door. The hinge module includes a housing, a rotational axis member disposed in the housing serving as a center of rotation between the pull-down door and the main body, an inner link housing movably disposed in the housing that moves with the opening of the pull-down door in a direction of the rotational axis member, and a damper installed in the inner link housing, the damper including a piston and a cylinder and providing damping force according to a relative movement of the piston and the cylinder. Any one of the piston and the cylinder of the damper moves with the inner link housing and the other of the piston and the cylinder of the damper moves by a predetermined distance as the inner link housing moves and then is interfered by the housing so as not to move further, and the piston and the cylinder of the damper starts damping, wherein the predetermined distance corresponds to an opening angle of the pull-down door in which the damping is started.

During the transition from the opening to the closing movement of a glove compartment door, or vice versa, undesirable noises (“clicking”/“popping”) can be reduced by providing regions of a housing surrounding a rotation damper with a contact region made of a material having a lower modulus of elasticity than the material of the remainder of the housing.

A door hinge with a damping function which is implemented according to the flow of oil when opening and closing a door so that a buffering force is applied during opening of the door, closing of the door is carried out smoothly. Due to rapid return of a damper unit, the damper unit immediately operates even when the door is closed immediately after being opened, thereby enabling smooth opening and closing of the door.

A head unit system for controlling motion of an object includes an environment sensor and a head unit device that include shear thickening fluid (STF) and a chamber configured to contain the STF. The chamber further includes front and back channels. The head unit device further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber to abate an external factor of concern associated with an external environment as sensed by the environment sensor.
