A contact lens having a rotational stabilization mechanism thereon, such as a prism ballast, and a thickness profile that reduces the torque imparted on the lens by the action of the eyelids, especially for stabilizing toric lenses. The control system includes an engine movement module that selects from N engine rotation modes based on camshaft movement and crankshaft movement, where N is an integer greater than two, and where at least one of the N rotation modes is an assisted spinning mode. A new economical printing process to increase document security by the use of neon fluorescent ink, printed onto paper in predetermined patterns and densities, whereby allowing the design to perform dramatic transformations under ultraviolet light and through electronic scanning. The method further includes obtaining a measured plasma frequency that exists after the plasma is struck, the measured plasma frequency value having a first value when the plasma is absent and at least a second value different from the first value when the plasma is present. The porous filler material is a material having ligaments that collapse resulting in a densification of the porous filler material in response to impact loading or a compression force sufficient to cause failure of the combined assembly.
