Abstract: Systems and methods are described for controlling a breakaway feature in a sliding door. The sliding door can be mounted in a doorway on a door hanger. The door is typically attached at one end using a hinge mechanism and maintained in planar alignment with the doorframe by a controllable mechanism such as an electromagnetic shear lock. An activation switch, such as a push-bar switch, initiates a delayed egress sequence that disengages the shear lock by controlling an energizing current in a magnet. When the shear lock is disengaged, the door can swing on the hinged mechanism. The delayed egress sequence can include one or more delays prior to disengaging the shear lock. Override signals can inhibit or force disengagement of the shear lock.

Abstract: An example of a horizontal side-moving door with a side-winding or horizontally translating curtain includes an upper seal comprising an upper edge of the curtain sliding within a groove of a seal guide. To protect the door in the event of an impact, at least a portion of the curtain's upper edge can restorably pull out from within the groove. To avoid damage in certain situations, the seal guide might resiliently deflect as well. After an impact, the curtain's upper edge is automatically fed back into the groove by simply opening and closing the door. During normal operation, the curtain's upper edge advantageously deflects in response to air pressure against either side of the door. In some examples, the seal guide is of a uniform cross-section, which makes the seal guide easy to manufacture by way of a conventional plastic extrusion process.

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.

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.

Abstract: Emergency release burglar bars having electronic locks that are actuated remotely by a signal generated by a smoke detector alarm provide security and will automatically unlock upon detection of smoke in the premises without human intervention to allow safe exit from the premises, and easy access and entry to the premises by emergency personnel. When the smoke detector/alarm senses smoke in the premises, its alarm is “powered on” to sound the alarm. A relay connected with the alarm circuit is activated simultaneously with the sounding of the alarm, which activates an “unlock” switch of a transmitter connected with the relay to transmit an RF “unlock” signal. Receivers on each of the electronic locks receive the transmitted signal, and activate an actuator, which actuates a mechanism to retract the bolt of the lock, allowing the burglar bars to be swung open.
