An electronic device includes a requesting application and a hosting application. The arithmetic unit carries out a total circumferential scanning, extracts a frequency component, carries out a scanning of a reference designation pattern, and calculates the angle displacement of the rotation shaft based on a phase difference of the frequency component and the number of frequencies corresponding to a change in a position of the reference designation pattern. When not actively transmitting, a WRAN cells remains in a passive, receiving mode to accept data. In addition, the method sends a push signal to the catalog when this detection takes place. Then a current step in the movement of the automated machine is executed.
