    摘要: An opening and closing body control device includes a distance detection unit that detects a detection distance, which is a distance to a detected object around an opening and closing body, and a control unit. When a start command is input, the control unit determines whether the detected object is a moving object or a stationary object, sets a first or second collision determination distance as a collision determination distance depending on whether the detected object is moving or stationary. When the detection distance is smaller than the collision determination distance, the control unit controls the drive unit to stop operation of the opening and closing body.

    摘要: A door control device stops a door such that the door does not come into contact with an obstacle existing in a rotation range of the door. The door control device includes: a distance calculation unit configured to calculate a distance from the door to the obstacle; a speed calculation unit configured to calculate an actual speed of the door; a braking force setting unit configured to set a braking condition indicating transition of a braking force applied to the door; a speed estimation unit configured to estimate transition of an estimated speed of the door from start of braking until the door stops; and a braking force correction unit configured, during braking, to correct a braking force such that the braking force is increased, or reduced, when a time gradient of the actual speed is gentler than, or steeper than, that of the estimated speed.

    摘要: A method for controlling a door, comprising the steps of storing energy during a manual opening of a door, sensing an object within a doorway, selectively applying a force derived from the stored energy, to close the door, based on the sensing of an object in the doorway. The closure is preferably controlled by an electronic control. A door closing device comprising an energy storage device for storing energy during door opening and releasing the stored energy to subsequently close the door, a damping system for damping a closure of the door, a sensor for detecting an object within a doorway, having an output, a controllable device for selectively restraining the energy storage device from closing the door, and a control system for controlling the controllable device based on the output.

    摘要: A movable barrier operator includes a communication interface configured to receive commands that cause the motor to move the movable barrier. The movable barrier operator further includes a processing circuit configured to cause the motor to automatically move the movable barrier from a first open position toward a closed position and then from the closed position toward a second open position different from the first open position in response to receipt of an intermediate open command by the communication interface. The processing circuit can also cause the motor of the movable barrier operator to move the movable barrier toward the first open position in response to the processing circuit determining that the movable barrier had been obstructed while moving from the first open position toward the closed position.
