Abstract

ENSEMBLE ELECTRIQUE DE MEMORISATION D'INFORMATIONS CONCERNANT LA MARCHE D'UN VEHICULE. L'ENSEMBLE COMPREND UNE 1 MEMOIRE RAM ET UNE 2 MEMOIRE (PROM, EPROM OU REPROM) AVEC DES COMMANDES PERMETTANT DE NE GARDER DANS LA 1 MEMOIRE QUE LES RENSEIGNEMENTS LES PLUS RECENTS ET DE FAIRE PASSER CES INFORMATIONS DANS LA 2 MEMOIRE EN CAS DE PANNE DU COURANT DE BATTERIE ETOU D'ACCIDENT. APPLICATIONS : MEMORISER DES INFORMATIONS COMME LA VITESSE, L'ACCELERATION, ETC., DE VEHICULES AUTOMOBILES ET FIXER CES RENSEIGNEMENTS EN CAS D'ACCIDENT.ELECTRICAL SET FOR STORING INFORMATION CONCERNING THE MARKET OF A VEHICLE. THE SET INCLUDES A 1 RAM MEMORY AND A 2 MEMORY (PROM, EPROM OR REPROM) WITH COMMANDS ALLOWING TO KEEP IN THE 1 MEMORY ONLY THE MOST RECENT INFORMATION AND TO TRANSFER THIS INFORMATION INTO THE 2 MEMORY IN THE EVENT OF A FAILURE FROM BATTERY CURRENT OR ACCIDENT. APPLICATIONS: SAVE INFORMATION SUCH AS SPEED, ACCELERATION, ETC., OF MOTOR VEHICLES AND FIX THIS INFORMATION IN THE EVENT OF AN ACCIDENT.
