A system and method for offset protection data in a RAID array. The scale-like inorganic particles are those with the surface coated with resin, and are characterized in that the 100% modulus of the resin in the tensile test is in a rage from 50 to 3000 Ncm2. According to the above structure of the present invention, since the display device such as liquid crystal cell or the like and the secondary battery are integrally assembled to form a module structure, the display unit can be made compact and thin to attain a light weight. The method determines a first integral energy spectrum of the cosmic radiation while the scintillator is upright, and a second integral energy spectrum while the scintillator is in a horizontal position. The data traffic is configured to traverse the director device arrangement irrespective whether the power is provided to the circuitry of the director device arrangement. Security thread or strip includes a plastic foil having a hardened coating comprising magnetic or magnetizable pigment particles oriented to represent graphic information.
