A communication device having a chip card configured to authorize a communication, the chip card having an interface connected to a communication controller via a modified standardized bus communication, a first and at least one second data source configured to connect to the communication controller. An engine control module communicates with the cam phaser to introduce the cam phase angle \u03b8 while an engine is being started. A modified region M3 is formed within the wafer 11, and a fracture a3 extending in a direction parallel to the thickness direction of the wafer 11 and tilted with respect to the plane including the lines 5 is generated from the modified region M3 so as to connect with the fracture b2. The PBX communicatively couples to a wireless local area network. The data structure includes data self describing the stored current configuration data, such that a conversion function can easily access the self describing information and render the stored configuration data platform independent. Third and fourth drivers may also be included.
