Abstract: A system for moving a barrier protecting a restricted area. A stationary linear induction motor moves the barrier by applying a magnetic field from the linear induction motor to a reaction fin attached to the barrier. The reaction fin has a rectangular beam or protrusion forming a groove on each side, which is engaged with guide members to guide the barrier. Holes are evenly spaced along the length of the reaction fin. Magnetic sensors sense the holes during movement of the barrier to determine the speed, position and direction of the barrier. A locking mechanism engages a pin into any one of the holes to lock the barrier in a fixed location. A heater is disposed within the rectangular beams or protrusions of the reaction fin to melt ice in cold weather environments. The system is operated by a main control logic that receives input data from the electronic sensors and controls the linear induction motor, heater and locking mechanism.
