摘要

The invention relates to the recognition techniques clinical]. / p & & p & a sensor according to the invention comprises, in particular, a decision circuit 34 which compares a sample of the current signal s with a sample of the signal recorded and with the previous state of the system. When a decision can be taken to a sample current, it is registered in series in a memory 38 to be read subsequently. When a decision may not be taken to a sample current, that - it is recorded with an indication of its position in the pharmaceutical, in order to form the subject of a decision subsequent. / p & & p & application to the recording magnetic a high density.
