An apparatus is provided for fracturing a shell of a three-dimensional object. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop. Also, the present invention relates to rating consumer lenders based on the predicted spend capacity of their consumers. The method generates and outputs pressure control valve commands based on a detected current hydraulic pressure, a detected temperature, and the target hydraulic pressure by implementing proportional integral derivative calculations and sliding mode calculations while carrying out a closed loop pressure control. According to yet another aspect of the system, each of the correlators maintains a corresponding X-component segment of the master scrambling code.
