Abstract: A method for producing a result prepared from asynchronous external events, wherein two mutually independent counting processes are activated, the temporal coincidence of the ends of counting of these two processes are verified and, on the basis of the information elements pertaining to the verification of each of these two counting processes and according to a specific sequencing of the application considered, a non-consolidated intermediate action is activated for each of the two sequencing processes and, after the verification of the temporal coincidence of the intermediate actions, and taking account of possible external priority actions, a resultant action is produced if all the necessary conditions are fulfilled.
