In a method for the commissioning of a door or window closer which comprises an energy accumulator, a damping device with an electric motor being operable as a generator and a transmission element, the leaf is opened and/or closed at least once in a teach-in process, the angular position of the motor shaft is detected during opening and/or closing, a functional relationship is determined between the angular position of the motor shaft and an angular position of the rotatable leaf at least over an area of the opening width of the leaf and the functional connection is automatically taken as a basis for a subsequent actuation of the electric motor for the damping of the closing movement of the leaf.

The invention is systems and methods of operating a window with an automated window mechanism. The systems and methods include moving with the automated window mechanism a sliding panel of a window relative to a window frame to open or close the window. The sliding panel moves through a proximate closing zone. The method also includes in the proximate closing zone, operating the automated window mechanism in a limited state comprising at least one of reduced velocity, reduced current to the automated window mechanism, or reduced voltage to the automated window mechanism.

A method for detecting potential pinches caused by at least one powered movable panel between a closed position and an open position, by: measuring a physical quantity at a plurality of panel positions when the panel is moved towards the open position so as to get a first profile, measuring said physical quantity in a reference position, when the panel is moved towards the closed position, and determining an offset value, determining a second profile by shifting the first profile of a shifting value, measuring said physical quantity in a repetitive manner when the panel is moved towards the closed position so as to get a third profile, and detecting a potential pinch if the third profile crosses the second profile.

A furniture drive system includes: a support for mounting the system on a furniture carcass; an actuating arm device movably mounted on the support and to be connected to the movable furniture part; an electric motor to be connected to the actuating arm device to move sections of the actuating arm device; a drive device separate from the electric motor for exerting a force on the actuating arm device; an adjusting device for adjusting the force to be exerted by the drive device; and a control device for controlling the electric motor. The control device has a determining device for determining the force to be exerted on the actuating arm device, and the drive device has a damping device to dampen a closing movement and/or an opening movement of the actuating arm device. The determining device is designed to perform a damper analysis of the damping device.

An electric apparatus includes a housing; a door rotationally arranged on a side of the housing; a sensor configured to detect rotation of the door; a motor configured to provide torque to the door to rotate the door; and a processor configured to obtain an open angle of the door based on an output signal of the sensor and control the motor to open the door to a target angle set by a user.

A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

The invention relates to a method of operating a swing door, whereby a drive moves a door leaf from a first position of the door leaf to a second position of the door leaf. For providing an operation of the swing door in a more effective and/or efficient way the method is characterized in that the drive adds an additional driving force and/or torque to the door leaf in the first position and/or the second position of the door leaf in relation to an external driving force and/or torque acting on the door leaf to hold the door leaf in the first position or second position, respectively.

A movable component of a motor vehicle, for example a tailgate can be moved between two end positions by a drive unit of a moving device. A release energy for the drive unit, which is to be used to release the component at the start of a movement from a starting position, is selected as a function of the starting position.

An apparatus is provided an includes a measuring device that measures a physical quantity representative of a movement of a panel between a closed position and an open position. A processing device: measures the physical quantity when the panel is moved towards the open position; measures the physical quantity in a reference position when the panel is moved towards the closed position; determines, for the reference position, an offset value between the physical quantity measured when the panel is moved towards the closed position and another value of the physical quantity measured when the panel was moved towards the open position; determines a second profile by shifting the first profile based on the offset value; repeatedly measures the physical quantity when the panel is moved towards the closed position to obtain a third profile; and detects a potential pinch if the third profile crosses the second profile.

Method and system for motor-driven assistance of the movement of a vehicle door, wherein the vehicle door is driven by means of an electric motor, which is controlled by a control unit, depending on a force exerted on the vehicle door by an operator, in a manner assisting this force or exceeding the force, comprising the steps: the voltage induced in the electric motor due to the force exerted on the vehicle door by the operator is detected and transmitted to the control unit, this electrical voltage or a signal derived from it is compared with prescribed threshold values in the control unit during a defined, adjustable time interval, and the motor is driven by the control unit, depending on whether the threshold values are exceeded or undershot, in a manner merely assisting the force exerted on the vehicle door by the operator or exceeding the force.
