Systems and methods for navigating within snapshots are provided. The motor may be two opposed radial piston hydraulic motors, to drive an upper king roller, which contacts the outside of the ring, which is inserted between the upper king roller and a lower mandrel roller, which contacts the inside of the ring. Since an electromagnetic field mode alleviating portion formed of a dielectric material is provided to the core wire of the coaxial cable, the thin and small size optical transmission module M can assure less amount of radiation of an interference electromagnetic wave, high frequency characteristic through connection with the coaxial cable. The tabs provide additional area for the bonding site to ground wires from the semiconductor chip by increasing the length of the chip paddle. In the columns, at least one extra control signal is used for the sampling of the reset level for the ALC pixels, which happens later than the sampling of the reset level for the image capture pixels. The steam flows successively through the high-pressure, medium-pressure and low-pressure modules.
