The disclosure relates to a corner bracket (14, 16) for a vertical moving door (2), the corner bracket (14, 16) comprising: a base plate (32) configured to be attached to the door (2); and a guide path (34) for a lift cable (4, 6) arranged in the base plate (32). A switch (28) is arranged in the base plate (32) and configured to be actuated by the lift cable (4, 6) in the event of a breakage of the lift cable (4, 6). The disclosure further relates to a method, performed by a control device (200), for stopping a vertical moving door (2) of a vertical moving door system (100), the vertical moving door system (100).

Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect drive-fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals.

A method for the operation of a motorized flap arrangement of a motor vehicle, wherein the flap arrangement has a flap which is pivotable with respect to a motor vehicle body, wherein the flap arrangement has a back-driveable drive arrangement for the motorized adjustment of the flap and a control arrangement for controlling the drive arrangement. It is proposed that an, in particular gravitationally induced, predetermined flap deflection is detected by means of the control arrangement from a de-energized intermediate position of the flap in a monitoring routine and, in response to the detection of the predetermined flap deflection, a holding routine is triggered in which the drive arrangement is adjusted to a flap-holding position in a holding control circuit.

A door control system is provided. The control system includes a controller configured to control a door via a motor. The motor is powered by a battery and bypasses the controller via relays and/or switches when power to the controller is disconnected. The current of the motor may be monitored and/or displayed to confirm that the door is balanced.

A system for detecting broken springs in overhead doors having automatic door openers includes an automatic door opener having a motor, a sensor configured to monitor performance of the motor in the door opener, and a processor in communication with the sensor. The processor is configured to compare the motor performance with a predetermined threshold level and send an alert when motor performance exceeds the predetermined threshold level.

A gas strut active monitoring system for a gas strut includes a gas strut wear monitor connected to a base end of the gas strut and a strut end. The gas strut wear monitor is removable from the gas strut such that the gas strut is replaceable without replacing the gas strut wear monitor. The gas strut wear monitor is configured to monitor an output force of the gas strut, and output a signal indicative of a maintenance recommendation for the gas strut based on the output force.
