Local and global reduction of critical dimension asymmetry in etch processing is described. The side members are assembled into a rectangular structure with the members positioned to stand vertically upright on their edges. If it has moved into the range covered by a selected radio network base station, it initiates a switch-over of the network-side routing of connection requests which are directed to the terminal, and routes them via the selected radio network base station. A data processing station automatically compares the patient’s capability profile with the comparative capability profiles and selects and displays from the first database, one or more suitable training programs for which the associated comparative capability profile matches the patient’s capability profile to a prescribable degree of similarity. When the power switching module is coupled to the first transmission module and the transmission shaft rotates in a first direction such that the scanner moves to a first position, the scanner drives the actuator to drive the power switching module to be coupled to the second transmission module.
