Abstract: A method and system include monitoring to detect a crossing of a first geographic boundary and monitoring to detect a crossing of a second geographic boundary. When a crossing of the first geographic boundary and a crossing of the second geographic boundary are detected in succession, a first barrier system response is initiated. In some examples, when a crossing of the third geographic boundary and a crossing of the second geographic boundary are detected in succession, a second barrier system response is initiated.

Abstract: In order to secure a door in a locked (or locked open) position without a key, such as to resist a forced entry through the door, a removable, remotely-controlled door locking apparatus is provided, which includes a housing configured for temporary fixed engagement to a portion of the door. The housing has a front facing surface sloped forward and downward at an angle from horizontal as taken from a top to a bottom of the apparatus, and an actuator arranged therein so as to be substantially parallel to the sloping front facing surface between upper and lower ends thereof. The apparatus may further include a movable foot attached to the actuator and configured, under actuator control, to be extended in a lock state against a floor surface to secure the door or retracted in an unlock state, based on a wireless signal received from a remote smart device.
