A method and system for providing a magnetic memory is described. To adjust control signal values, a reference trajectory for the set-point is generated based on a set-point tracking tuning parameter. The system also includes at least one computer-readable tangible storage medium comprising executable code that, when executed by at least one processor, is operable to transmit signals to the display module that cause an electric field to be present in at least one pixel element of the plurality of pixel elements. The other end is a slanted end with a through-hole formed therein and a centrally located dome-shaped protrusion. A locking device is attached to the key housing and lockingly engages the turn table when the turn table is in the first position.
