AS conductive patterns 11A to 11D are formed burying in a insulating resin 10 and a conductive foil 20 is formed being half-etched, thickness of the device is made thin. The invention is characterized in that it does not comprise any step of physical or logical control for authorizing andor validating the transmitted data so that any data reception at a node is unconditionally followed by a retransmission, that is the control of the dataflows is implicitly determined by the cabled topology used. The write address is mapped to a physical address of a selected one of the paired memory pages. The processor may also be configured to selectively output navigation information for a route from the current location to a destination location via the output device based upon the at least one notification being output.
