    b) periodically, reading in the first memory sector the detailed representation of the data and processing said read data to produce a consolidated representation of the data of said first plurality of second time periods for a fourth time period;

    c) cumulatively memorizing in a second memory sector (12) the consolidated representations for a second plurality of fourth time periods, said second plurality of fourth time periods corresponding to the first time period; and
