Reducing timing skew begins with identifying signals that are to have a reduced timing skew. The adjustment device has an adjustment mechanism including an electric actuator, such as an electric motor, with plug-in connections. In one embodiment of the invention, a first magnetic domain control layer is provided in the proximity of the free layer of the GMR sensor in such a way that the track width is Twr1. The policy rule may be charging rule that causes a charging system to bill a subscriber account or a network access rule that blocks the signaling communications of the UE.
