Abstract: A gate system. The gate system comprises a fixed support and a barrier arm assembly pivotally mounted to the fixed support and being pivotable between an obstructing configuration, a forward non-obstructing configuration, and a reverse non-obstructing configuration. The motorized gate system also comprises at least one event detector configured to detect an occurrence of at least one forward opening event and at least one reverse opening event and a drive assembly operatively connected to the barrier arm assembly to rotate same clockwise and counterclockwise between the obstructing configuration, the forward non-obstructing configuration, and the reverse non-obstructing configuration. A method for controlling same is also provided.

Abstract: A controlled gate system for use in a restricted passage having an entry end and an exit end is described. The system comprises a barrier gate secured to a pivotal support assembly at the exit end to permit the barrier gate to pivot from a closed position, obstructing the restricted passage, to an open position, outwardly of the restricted passage to permit entry into an establishment. An electrically actuable brake, arrests the gate at the closed position and it is deactivated by a detector activated by a person at the entry end. An electromagnetic arresting mechanism is provided to disconnect the barrier gate from the electrically actuable brake to permit the barrier gate to swing freely within and out of the passage to provide for evacuation in emergency situations.

Abstract: A controlled gate system is comprised of a barrier arm which is pivotally connected to a first fixed support. A motion detector is secured to a second fixed support spaced a predetermined distance from the first fixed support and in alignment therewith to create a restricted passageway with the barrier arm normally resting in an obstructing position within the passageway. The barrier arm is arrested at the obstructing position by a solenoid actuated latch which is disengaged by the motion detector. The arc of displacement of the barrier arm is also restricted to permit passage through the passageway in a single direction. Under certain conditions a controller will permit the barrier arm to be disengaged to permit passage in the passageway in opposed directions. The motion detector of the preferred embodiment is constituted by a further barrier arm.
