Abstract
Door sensor(s) may be attached to a door body or bodies of automatic swing doors. The door sensor(s) may be equipped with door position detectors including geomagnetic sensor(s), the sensor(s) being itself or themselves capable of detecting position(s) occupied by the door body or bodies during opening and/or closing thereof. During opening and/or closing of the door body or bodies, determination may be made as to whether detected object(s) are object(s) intended for detection; and in the event that object(s) are object(s) intended for detection, opening and/or closing of the door body or bodies may be stopped, slowed, and/or reversed in correspondence to detected position(s) occupied by the door body or bodies during opening and/or closing thereof.
