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.

A playpen door, including a door frame; a door body movably mounted on the door frame; and a detection assembly mounted on the door frame and the door body and configured to detect open or closed state of the door body. The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

The disclosure discloses a driving device for door opening and closing, which includes: a box body; a permanent magnet synchronous motor arranged inside the box body, an output shaft of the permanent magnet synchronous motor extending along a vertical direction; and a gear set arranged inside the box body and connected with the output shaft of the permanent magnet synchronous motor, and a gear at a tail end of the gear set is provided with a connecting rotating shaft that extends along a vertical direction and is used for connecting a door panel. The above driving device for door opening and closing uses the permanent magnet synchronous motor as a driving source, which is matched with the gear set to implement transmission, the door panel is driven to rotate by the connecting rotating shaft on the gear at the tail end of the gear set.

A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

Motorized actuators for pivoting fenestration units that include both lock and open/close actuation, are addressed. Such actuators, and associated fenestration systems and methods, may achieve a variety of potential advantages, including egress functionality, ease of operation, active position control, aesthetically pleasing features (e.g., minimal design impact), intuitive controls, and others.

The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

An exemplary armature assembly is configured for use with a door closer comprising a pinion, and generally includes a first arm configured for rotational coupling with the pinion, a second arm pivotably coupled to the first arm at a pivot joint, and a hold-open mechanism. The hold-open mechanism generally includes a clutch having a decoupling and a coupling state, and an electromechanical driver operable to transition the clutch between the coupling state and the decoupling state. With the clutch in the decoupling state, a first torque is operable to cause relative pivoting of the arms. With the clutch in the coupling state, the first torque is inoperable to cause relative pivoting of the arms, and a second torque greater than the first torque is operable to cause relative pivoting of the arms.

A door opening and closing assisting apparatus that assists an opening and closing operation of a door on a vehicle is provided. The door opening and closing assisting apparatus includes: an information obtainer that obtains information on an opening and closing acceleration of the door; a door actuator that performs driving for assisting the opening and closing operation of the door; a target assisting power computer that computes a target assisting power for assisting the opening and closing operation of the door; and a controller that performs driving control for the door actuator based on the target assisting power. The controller starts the driving control for the door actuator at a timing at which the information obtainer obtains the opening and closing acceleration of the door.

An egress entrance system (1) comprising a swing door member (10) having a door leaf (12), an initiate device (13) for initiating a panic opening, and an automatic door operator (30) is provided. The automatic door operator (30) has a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and the automatic door operator (30) being operable in a testing mode (60) and an operational mode, wherein the controller (31) is configured, in the testing mode (60), to automatically determine at least one test parameter; and causing an action in response to the determined test parameter.
