A temperature sensor is disposed near an HC adsorbent in an exhaust system of an internal combustion engine. The flap portion is subdivided into a plurality of sections that cooperate to define a dunnage element. Each of the m capacitors has a first electrode and a second electrode, and the first electrodes are connected to each other. Further, the information code may be coded and decoded by using methods for coding and decoding and may be decoded by using an apparatus. The first of the navigation modules and the other of the navigation modules are connected by a communication link. Processes for their manufacture and pharmaceutical compositions containing them are also described.
