In a cable processing equipment a cable changer stands perpendicularly relative to a base plate, at which a straightening unit and a cable transport unit are arranged. The roller cutter profile may extend beyond the fixed cutter profile in the shoulder and gage sections, possibly with the fixed cutter profile extending beyond the roller cutter profile in the nose section andor a cone section. The mobile terminal device receives the map data and displays a map of the region such that the moving direction of the portable terminal device is aligned with a top of the map displayed in the display unit. An analog to digital converter converts the analog CW receive signal to a digital CW receive signal at a predetermined sampling frequency and a processor processes the digital CW receive signal in connection with CW Doppler imaging. The outer ratcheting collar and inner ratcheting ring firmly hold the piston, thus preventing inadvertent rotation and collapse of the piston during the shoring device application.
