A method, system, and computer-accessible medium are provided for safely modifying a host user interface with one or more extension user interfaces. The system includes pillar armor attachable after an original equipment manufacture door and hinge are removed. The second circuit is configured to receive the command detection signal, an operation mode specifying signal and a selection signal and generate a second signal which causes the start timing of the operation of a row-system circuit to be synchronized with the input timing of a second command. A force arm drive displaces the force arm at a high velocity to impact the secured structure. Related methods are also described.
