System and method for common mode translation in continuous-time sigma-delta analog-to-digital converters. In both instances the type bits included in the word or additional word contain dataset-global data which pertains to the underlying data structure. It may also be a pressure sensor which signals the deviation of the set pressure predetermined by the shield control device from the measured actual pressure in the form of a deviation signal. The different pieces forming the deterrent can be selected by the lineman to quickly build an optimal deterrent in the field. The task of determining a navigation route to a location that can be preferentially accessed is based on an efficient, structured search procedure of low computational complexity.
