The invention relates to substituted aromatic carboxamide and urea derivatives, to processes for the preparation thereof, to pharmaceutical compositions containing these compounds and also to the use of these compounds for preparing pharmaceutical compositions. The device is adapted to a specific ear of a specific individual. The methods generally allow communication nodes in the M2M network to process and route requests to access resources without having the central node having to process the requests. A feeder feeds the ground food product onto the conveyor belt adjacent an inlet of the unit. The burst error detecting unit detects a burst error based on a change in a state of occurrence of a bit error in the predetermined byte in a predetermined time window.
