In a driver, supposing that an angular position of the rotator in a state where a coupler coupling a link member and the rotator together is located at a rearmost position is regarded as a reference angular position, a first angular position is an angular position where the rotator is shifted from the reference angular position in a first rotation direction by an angle 1, and a second angular position is an angular position where the rotator is shifted from the reference angular position in a second direction opposite to the first rotation direction by an angle 2 smaller than the angle 1. The driver has a regulating portion which does not allow the rotator to rotate in the second rotation direction from the second angular position.

Provided is a swing door operator (110) for moving a door leaf (120) between a first position and a second position. The swing door operator (110) is arranged to operate in a powered and a powerless mode and comprises a permanent magnet DC motor (310). The motor (310) is arranged to move the door leaf (120) at least from the second position to the first position in the powered mode. The swing door operator (110) further comprises a mechanical drive unit (320), arranged to move the door leaf from the first position to the second position in the powerless mode. In the powerless mode, at least one resistive device is electrically connected in parallel with the motor (310) and arranged to limit a current generated by the motor (310) in response to the movement of the door leaf (120) from the first position to the second position by means of the mechanical drive unit (320). A method for controlling the swing door operator is also provided.

A refrigerator and a method for controlling the same are disclosed, which may automatically open or close a door and a method for controlling the same. The refrigerator may automatically open or close door(s) of the refrigerator by controlling a motor. After lapse of a predetermined time after the door of the refrigerator has been closed, the refrigerator operates a motor with an output used when the door is not opened, such that the refrigerator may remove noise while simultaneously maintaining a constant door opening time when the door is opened. In addition, when the door opening signal time is detected, the refrigerator may immediately opens the door.

A method for determining a position of a door in a door system having a rail guiding a movable door element (50) of the door and a sensor element (10) for detecting movement of the door element along a free movement path of the door element (50), involves detecting a state of the sensor element (10) as the door element is moved to and fro. A door control determines the door changes in the state based on the position of the sensor element (10).

Systems, methods, and computer-readable media for vehicle object repositioning management, including door control mechanisms, rack control mechanisms, and roof control mechanisms, are provided.

The present invention estimates a height of a user by using a rear camera to automatically adjust the opening amount of a tailgate, so as to increase the convenience of an electrically-powered tailgate.

A vehicle has at least one flap, at least one flap drive, which is configured to open and close the at least one flap by changing a value of a state parameter of the at least one flap. A control device is configured to control the at least one flap drive in order to open the at least one flap up to an adjustable value of the state parameter of the at least one flap and to close the at least one flap. A communication device is configured to communicate wirelessly with at least one external communication device, and to periodically determine a distance of the communication device from the at least one external communication device, if a communication connection is established between the communication device and the at least one external communication device. The control device is configured to set the adjustable value of the state parameter of the at least one flap to a predetermined value of the state parameter of the at least one flap during a period in which the control device periodically determines that the distance is less than a predetermined threshold distance.

An electric apparatus and a control method thereof. The electronic apparatus including a housing; a first door rotationally arranged on one side of the housing; a second door rotationally arranged on the other side of the housing; a first motor operationally connected to the first door; a second motor operationally connected to the second door; a first motor driver electrically connected to the first motor; a second motor driver electrically connected to the second motor; and a processor electrically connected to the first motor driver and the second motor driver, wherein the processor may control the first motor driver to drive the first motor to close the first door at a time different than a time the second door that is connected to the second motor driven by the second motor driver closes.

A method and an assembly for pivoting a movable component having a drive device with an electric drive motor in order to influence a pivoting of the component between a first setting and a second setting. A position sensor detects a position measure for a setting of the component and a speed parameter for a displacement speed of the component. During a displacement of the component with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. The setpoint voltage is increased if a current intensity flowing through the drive motor is lower than the electrical setpoint current intensity, and the setpoint voltage is reduced if the current intensity flowing through the drive motor is higher than the electrical setpoint current intensity.

A powered garage door pivots about a fixed pivot axis extending between side edges beneath the top edge of the door panel, such that when moving from the closed position to an opened position the top edge moves rearwardly while the bottom edge moves forwardly. A front top header finishing plate is fixed so as to extend downwardly from the header in front of and beneath the top edge of the door panel. An inclinometer sensor is secured to the door panel, sensing the angle of the door panel as it pivots between closed and opened positions. Hydraulic cylinders, which can be housed within uprights defining the door opening, are controlled by the electronic controller based on the inclinometer signal, and a graphical user interface allows the user to set both zone sizes (based on inclination angle) and zone speeds, independently for opening and closing.
