Abstract (en)
[origin: EP1950629A1] A method for counting events with a volatile counter (109) and a non-volatile electronic memory comprising a number N of memory areas (111), in an apparatus (101) having an operative mode and a non-operative mode, comprising the steps of: a) counting events with the volatile counter (109), b) when the count value has been incremented by a predetermined number M or when the apparatus (101) passes into the non-operative mode, saving the count value to one of the memory areas, with cycling switching of the memory area into which the count value is written; and c) when the apparatus (101) passes into the operative mode, initialising the counter (109) with the maximum of the count values stored in the N memory areas.
