The invention relates to an actuator with an anti-backbend chain, a drive motor, and a worm which can be driven by the drive motor and which comprises a helical groove. The anti-backbend chain has engagement means and is guided along the worm, and the chain is in engagement with the worm by means of the engagement means and the helical groove to drive the anti-backbend chain. Such an actuator should have a more compact design and should optionally exhibit less wear. For this purpose, the core diameter of the worm is larger than twice the distance from the motor axis to the motor exterior along which the anti-backbend chain is guided, and the anti-backbend chain is guided at least partly along the drive motor by means of the engagement means.

A control arrangement for an entrance system, having one or more movable door members and an automatic door operator for causing movements of the one or more movable door members between closed and open positions, includes a controller and one or more sensor units. Each sensor unit is connected to the controller and arranged to monitor a respective zone at the entrance system for presence or activity of a person or object. At least one sensor is an image-based sensor unit having an image sensor arranged for capturing an image of an external object, a memory arranged for storing a plurality of settings for the image-based sensor unit, and a processing device. The processing device is arranged for processing the image captured by the image sensor to identify a machine-readable optical code therein, deriving a configuration instruction encoded by the optical code, and executing the configuration instruction.

A brake module for a drive system, in particular for doors, including at least one thrust washer and at least one brake disc, wherein the at least one thrust washer and the at least one brake disc each have at least one friction surface rubbing against each other during braking operation is provided. The embodiments also relate to a drive system, in particular for doors, including such a brake module. The embodiments further relate to a production method for a brake module of the abovementioned type. Known brake modules have a high variation in the braking force on the one hand in the course of their service life and on the other hand as a function of the temperature.

An air control system with an integrated diagnostic device for a motor vehicle includes: a carrier structure, an air output opening, a closing element arrangement with one or several closing elements adjustably placed on the carrier structure, a power unit which is constructed to adjust the closing element arrangement in an adjustment movement, a diagnostic device to acquire information about the condition of the closing element arrangement, an interface to convey data at least from the diagnostic device to another device, wherein for at least one closing element of the closing element arrangement the air control system also includes a resistance element associated with said closing element which is constructed to temporarily change the torque or force required in a predetermined phase of the adjustment movement for the adjustment of the closing element arrangement, wherein the diagnostic device acquires at least one operating parameter of the power unit as information about the status of the closing element arrangement.

The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).
