A global content directory includes a directory structure that includes a plurality of product classes organized in a hierarchy. The braking system further includes a pressure relief valve for limiting the hydraulic pressure applied to the slave cylinder only when the vehicle is in road mode. At least one gate structure is formed on the SOI region that is between the N-type and P-type doped regions. The phase is adjusted using the frequency offset. Wrong correspondence is removed by verification to determine a positional relation among range images. The distance between the ink marks is measured using the optical scan.
