A method provides a protected region of a data storage device associated with a computational device, where data in the protected region is primarily protected by preventing access without proper access authorization. The electrical surge protection device includes a support that is structured to be installed on the electrical enclosure and a number of varistors or other electrical components that will, in the event of a voltage surge on a line conductor, shunt electrical energy from the voltage surge to the ground or neutral conductor with which it is connected. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. Gate electrodes are formed on the insulating layer. The inner chamber is sealed in air-tight manner with respect to a space between the inner chamber and the outer chamber while the space is maintained at a vacuum pressure. The carbonaceous complex structure includes a substrate 1 of quartz or glass, on which are layered a carbonaceous thin film 2 and a fullerene thin film 3.
