A pin electronics circuit for use in automatic test equipment is disclosed. The emergency switch is positioned on an edge of the mobile device in a position that is visible and operable without activating the device. Search results are gathered from each selected search engine. When a specified playback rate is requested, the intercoded frames are retrieved using the index. The inductance and the permanent magnet are arranged such that, under a vibration on the circuit arrangement, the permanent magnet is moved relative to the inductance such that an electrical induced voltage for supplying the functional unit with electrical energy is induced by the inductance.
