Abstract
The device includes data entry means (10), control means (14) connected to means (12) for displaying said data. The invention is characterised in that it further includes a processing unit (16) inserted between the data entry means (10) and the control means (14). The processing unit (16) includes a memory (11) for storing reference times and particularly the Time Out, a counter (18) storing the time TC that elapses from the start of a manipulation and the time TM the elapses between two manipulations, and a comparator (21) including a first comparison unit (23), which acts on the one hand on an ON/OFF switch (24) to interrupt, via control means (14) the energy supply when TC>TO and which, on the other hand, enables TO to be altered at the end of a series of manipulations as a function of certain reference times of the memory and the speed at which the manipulations have been carried out.
