Disclosed is a method (50) of providing finger pinch protection at a hinge area of a swing door-based entrance system (1) having a motorized automatic door operator (30) for opening (2) of the swing door (10) in an automatic mode of the entrance system (1), wherein the entrance system (1) also has a manual mode in which a human user may cause opening and closing of the swing door (10) by manual force. The method involves monitoring (52), by a first sensor function (S1), for presence of a person or object in a first zone (PD) at the first door leaf surface (12-1) and non-proximate to a vertical door edge (14). The method also involves monitoring, by a second sensor function (S2), for presence of a person or object in a second zone (PDHA) at the first door leaf surface (12-1) and proximate to said vertical door edge (14). When any of the first sensor function (S1) or second sensor function (S2) detects presence in the first zone (PD) or second zone (PDHA) in the automatic mode during an ongoing opening of the swing door (10), the automatic door operator (30) is controlled so as to stop opening of the swing door (10). When the second sensor function (S2) detects presence in the second zone (PDHA) in the manual mode, the automatic door operator (30) is controlled so as to counteract an attempt by a human user to manually open the swing door (10). A corresponding entrance system (1) is also disclosed.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include one or more rows of emitters configured to generate an emission beam. The emission beam may have a width that is at least a width of an opening below the door sensor. The IR sensor may also include one or more rows of receptors configured to receive an evaluation beam. The receptor beam may have a maximum width that is at least the width of the opening. At least a portion of the receptors may be further configured to be one or more of deactivated and ignored, such that the width of the evaluation beam is reduced to correspond with a reduced width of the opening during a closing of a door.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include a plurality of emitters arranged in multiple rows. Each emitter of the plurality of emitters may be configured to emit an emission beam comprising IR light. A plurality of receptors may be arranged in multiple rows. Each receptor of the plurality of receptors may be configured to receive a reception beam comprising the IR light reflected off of a surface. One or more lenses comprising refractive elements may be configured to duplicate and direct one or more of the emission beams and one or more of the reception beams onto the surface to form an IR pattern. The IR pattern may include multiple IR curtains. One or more of the receptors and/or emitters may be deactivated to change a width of the IR pattern and/or number of IR curtains.

A door control system is provided. Aspects includes a sensor having a field of view in proximity to a door threshold of an entrance to an occupancy area, wherein the sensor is adapted to detect objects in the door threshold and a landing area proximate to the door threshold, wherein the sensor is operated based on a movement of a door in the door threshold. And based at least upon detecting an object within a portion of the door threshold or the landing area, the sensor operable to signal a door operation controller to perform an action.

When the second sensor function (S2) detects presence in the second zone (PDHA) in the manual mode, the automatic door operator (30) is controlled so as to counteract an attempt by a human user to manually open the swing door (10). A corresponding entrance system (1) is also disclosed.

The invention relates to an automatic door and method for controlling an automatic door (10), comprising a door controller unit (70) for controlling a door, acting on a door drive; further comprising a monitoring system (11) comprising at least two door sensors (12, 32) mounted on two opposite sides of the door, as seen in passage direction, where each of said sensors (12, 32) comprises a scanning unit (16, 36) that monitors a sensor safety area, where a safety signal is applied to the door controller unit upon detection of an object within the sensor safety areas of said sensors. According to the invention after a predefined timespan (TL) of no detection within said sensor safety areas of said sensors, the monitoring system (11) is set to a restricted mode in which at least one sensor safety area is set to a restricted area, where the safety signal is then provided upon detection of an object within the restricted area, where further, once a detection in the restricted area occurs, the monitoring system is set back to an unrestricted normal mode.

Systems, methods, and non-transitory computer readable media may be configured to control wind up of windows. A window of a vehicle may be controlled to start a window closing motion. Interior activity information for the vehicle may be obtained. The interior activity information may characterize activity inside the vehicle. A window obstruction event for the window may be detected based on the interior activity information. The window obstruction event may include an object obstructing the window closing motion. Responsive to detection of the window obstruction event, the window closing motion may be stopped before the window touches the object.

The invention relates generally to the field of barrier control systems and in particular relates to barrier control systems, such as a garage door opener, with auxiliary power supply and auxiliary power supply for barrier control systems. A barrier control system, such as a garage door opener, with an auxiliary power supply and an auxiliary power supply for a barrier control system are described. The auxiliary power supply includes a backup battery and a light source that is operable on DC power. The auxiliary power supply includes a sensor to detect whether a DC motor of the barrier control system is powered by the backup battery, and switches on the light source upon detecting the DC motor being powered by the backup battery.

A door arrangement (1), includes a safety device. A door arrangement monitoring 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).
