Methods and apparatus for performing a data migration in a clustered computer system. One or more image acquisition systems are adapted to produce a series of overlapping images of a gas bearing supported spherical inertial sensor assembly. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces. , to thereby form a corrosion-resistant film containing fine zinc particles dispersed therein. The oxygen, when used, allows for some oxidation of waste by-products and provides an additional offset for thermal requirements of operation. A clamping edge at the extremity of the first end of the second resilient contact leg engages the bare wire and cooperates with a first edge of the window opening to prevent the withdrawal of the bare wire from the window opening.
