Abstract

"EQUIPAMENTO MóVEL PARA USO NãO ESTACIONáRIO". A presente invenção provê um equipamento móvel (1) para uso não estacionário, incluindo um relógio de tempo real (RTC) (7) integrado no equipamento móvel (1) para gerar uma informação de tempo real, um gerador de tempo de sistema (9) integrado no equipamento móvel (1) para gerar uma informação de tempo de sistema adicionando um desvio à informação de tempo real dada pelo RTC (7), uma memória não volátil (8) para o armazenamento permanente de dados e um meio de entrada (4) para introduzir instruções para mudar a informação de tempo de sistema. Por este meio, meio para limitar as possíveis mudanças da informação de tempo de sistema geradas pelo gerador de tempo de sistema (9) para uma faixa de tempo prefixada e meio para limitar o possível valor de reiniciação do RTC (7) de acordo com os dados armazenados na memória não volátil (8) são providos.
