The invention relates to a switching device for switching an electric motor, comprising a control unit which is configured to provide a first switching signal for the electric motor, a memory which is configured to store at least one end position, and a position sensor which is configured to provide the control unit with an electrical position signal which indicates a measured position, wherein the control unit is connected communicatively to wireless communication means and is configured to store the measured position in the memory as said at least one end position on the basis of the position signal in response to a received first instruction, and wherein the control unit is configured to provide the first switching signal by comparing the stored end position and a position signal measured by the position sensor. The invention also relates to a drive with such a switching device and a method for setting up such a switching device.

An opening and closing body drive mechanism that drives an opening and closing body between an open position and a closed position; a drive unit to drive the opening and closing body; a detecting unit to detect movement of the opening and closing body; and a control unit to control driving of the opening and closing body. The control unit carries out a feedback control to control driving of the opening and closing body such that the movement of the opening and closing body, detected with the detecting unit, matches a predetermined target value when no abnormality occurs in the detecting unit or in wiring connecting the detecting unit and the control unit.

A door arrangement monitoring method, a safety device (5) and a door arrangement (1), including the safety device (5), are provided. The method monitors a monitored area positioned in front of a door opening, offset and parallel to a door closing plane, and performs a failure routine when an object (6) is detected in the monitored area and there is a risk of a collision of the object (6) with a door leaf (2). A current position of the object (6), and of a leading edge (23) of the door leaf (2), are detected. A direction of movement of the door leaf (2) is detected. The failure routine is initiated as a function of the current position of the object (6) and the leading edge (23) of the door leaf (2) as well as the direction of movement of the door leaf (2).

A door closer assembly for an entryway device having a position sensor that assists in determining the location of the door closer assembly, and thus the location of the associated entryway device, relative to at least an entryway. The position sensor can be coupled to, and/or part of, the door closer assembly. Information obtained by the position sensor may be used by one or processing devices of an access control system to determine whether the door closer assembly and/or the entryway device is at the closed location, among other locations, as well as the direction(s) of displacement of the entryway device. Such information may be utilized in calibrating other devices, as well as determining the occurrence of a number of events, including unauthorized displacement or holding of the entryway device. A timer may also be utilized to further evaluate the nature of the displacement of the entryway device.

A geared motor is provided, including an electric motor, a transmission, a drive shaft and a switching device arranged on the drive shaft. The switching device includes a single housing that is distinct and separate from an electric motor housing and a transmission housing. The switching device also includes a contactless, absolute position-measuring device and an evaluation unit, each provided within the single housing, a gear wheel coupled to the drive shaft, and an output unit. The switching device is coupled to the position-measuring device by a pinion, which rotates about the same rotational axis as the drive shaft.

The disclosure relates to a method at a control device (100) for controlling an overhead door operator system, the overhead door operator system (1) being configured for opening and closing an opening (2), and comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11). The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages. The disclosure further relates to an overhead door operator system for opening and closing an opening.

A transmission mechanism for a vehicle door handle is provided, the handle including a handle lever, movable between a flushing position and a ready position, the mechanism attachable to the lever and to an electric motor, and including a lever shaft connectable to the lever, a rotation of which causes motion between the positions; a reduction mechanism to adapt an output torque of the motor into a rotational motion of the shaft, including first and second reduction stages each having a worm drive, the first including a first worm and a first worm gear, and the second having a second worm and another worm gear rotationally coupled to the shaft; and a brake mechanism frictionally engaging a rotating element of one of the stages when the shaft reaches a rotational braking position between the positions to stop the shaft in a position where the lever is in the ready position.

Disclosed is a door system comprising: at least one travelable door element; at least one running rail for guiding the door element; and at least one light barrier element for detecting a free travel path of the door element, wherein the at least one running rail has a cut-out at or in which the at least one light barrier element is fastened.

A refrigerator and a control method thereof. The refrigerator includes a housing, a door configured to be rotatably coupled to the housing by including a hinge shaft and a hinge gear fixed to the hinge shaft, and a door opening and closing device provided at one end of the door to control opening and closing of the door. The door opening and closing device includes a drive motor, a final gear configured to receive power from the drive motor and transmit the power to the hinge shaft, the final gear arranged at one end of the door opening and closing device to interlock with the hinge gear, and a door position sensor arranged on one side of the final gear to detect a rotation angle of the final gear.

Automatic vehicle window control systems and methods are provided herein. An example method includes determining a first operating height of a first window of a vehicle, determining a second operating height of a second window of the vehicle, comparing the first operating height with the second operating height, and selectively adjusting the first operating height or the second operating height to be substantially equal to one another when the first operating height and the second operating height are not substantially equal.
