A method for operating a door system having a door leaf, which is movable by means of a door actuator, and having a sensor unit, which is arranged at a height above a floor of the door system and with which the approach of a person towards the door leaf is detected by means of a control unit, includes at least the following steps: determining a direct distance between the sensor unit and the person using the sensor unit; determining a horizontal distance between the sensor unit and the door leaf by a geometric relationship of the person, of the door leaf and of the height the sensor unit; and determining the probable approach time of the person on the basis of the determined horizontal distance and opening the door leaf. A door system having a control unit may be used to carry out the method.

A method for operating a door actuator of a pivot leaf door, having a pivotable door leaf, includes at least the following steps: performing a pivot movement of the door leaf; and identifying an interaction between the door leaf and a person and determining a correction value for the pivot movement of the door leaf based on the interaction and correcting future pivot movements of the door leaf by the correction value. A door actuator of a door system is configured to carry out the method.

A method for operating a door actuator of a door system, having at least one movable door leaf and a control device, which is designed to control the drive of the door leaf, and having a sensor unit, which is designed to detect at least one person in a region before the door system, and transmits information about the person to the control device, includes at least the following steps: a) detecting a person approaching the door system laterally, b) identifying a parameter set (P) having the distance (A) changing in time, the approach angle (□) and/or the speed (S) of the person relative to the door system, c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters and d) opening the door leaf only in the case of the determined desire to enter.

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.

The present invention relates to an apparatus and method for driving a moveable closure, such as a garage door. In an initialisation process in a setup mode for the door operator for driving a moveable closure between open and closed positions, the apparatus allows selection of opening and/or closing speeds for the closure from a plurality of predefined stored driving speeds. This selection, or the range of stored driving speeds available for selection, is made in accordance with the type of closure to be driven, and this may be established automatically by detecting certain characteristics of movement of the closure as part of the initialisation process.

A drive arrangement for motorized adjustment of a cargo-space-tailgate arrangement of a motor vehicle the cargo-space-tailgate arrangement including a cargo-space tailgate adjustable between an open position and a closed position, the drive arrangement includes an electric drive, for providing a drive force, and a control arrangement for activating the electric drive. The drive arrangement includes an output element and a drive coupling. The output element transmits the drive force to the drive coupling for motorized adjustment of the cargo-space tailgate. The control arrangement activates the drive in an adjustment routine for motorized adjustment of the cargo-space tailgate to assist an actuation action introduced manually the cargo-space tailgate, and the control arrangement activates the adjustment routine based on an activation preset that is dependent on at least one friction parameter of the drive.

The invention concerns a method for controlling a drive (5) for a leaf (1), in particular for a door leaf or a window leaf, including the following steps: Measuring a measured value (vr) of a kinetic quantity of the leaf (1), comparing the measured value (vr) with a tolerance range (TB) of a reference travel curve (SFK), driving the leaf (1) by the drive (5) according to the reference travel curve (SFK). Upon the measured value (vr) leaving the tolerance range (TB), the leaf (1) is set to a freewheel (FL) in which the drive (5) is suspended.

In one aspect, a remote server computer is provided for facilitating operation of movable barrier operator systems having imminent motion notification apparatuses. The remote server computer includes a processor, a memory, and a network interface for communicating state change commands to the movable barrier operator systems via a network. The remote server computer is configured to receive a confirmation indicating that a sensor check has been performed to test sensors of those systems. Upon receiving a state change request from a remote control associated with a movable barrier operator system, the processor may determine whether the confirmation has been received for that system, and if so, causes communication of an attended command signal that inhibits operation of an imminent motion notification apparatus of the movable barrier operator system. Otherwise, the remote server computer may communicate an unattended command signal.

A barrier control system running a program thereon, the barrier control system including a main body, a control unit disposed within at least a portion of the main body to execute the program to control operations of the main body, and at least one control device connected to the control unit to control operations of the main body through the control unit based on the program.

An entrance system (1) comprises a swing door member (10) having a door leaf (12), and a sensor unit (S1; S) mounted to the door leaf (12), the sensor unit comprising a door angle sensor (S1). The entrance system (1) further comprises an automatic door operator (30) having a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and a linkage (40) connected to the automatic door operator (30) and the door leaf (12) for transferring torque generated by the motor (34) to the door leaf (12). The automatic door operator (30) is operable in a learn mode (60) and an operational mode (70). The controller (31) is configured, in the learn mode (60), to automatically establish a linkage reduction curve (65) by determining, for a movement of said door member (10) between a shut closed position (18) of said door leaf and a swung open position (19) of said door leaf, the torque required by said motor (34) to cause movement of said door leaf (12) at different door leaf angles (α), the different door leaf angles being determined from measurement readings of said door angle sensor (S1). The controller (31) is configured, in the operational mode (70), to compensate for a non-linear torque transfer characteristic of the linkage (40) by applying the linkage reduction curve (65) when controlling said motor (34) to cause the door member (10) to swing open.
