Abstract

Patente de Invenção: "SINCRONIZAçãO DE UM RELóGIO DE BAIXA POTêNCIA EM UM DISPOSITIVO DE COMUNICAçãO SEM FIO". Um método e circuito para controlar uma estação móvel operando em um ambiente de alerta particionado. O circuito compreende um relógio ou "clock" de baixa potência para gerar um sinal de clock de baixa freq³ência; um gerador de sinal de clock para gerar um sinal de clock de alta freq³ência; um circuito lógico de sincronização para sincronizar o sinal de clock de baixa freq³ência ao sinal de clock de alta freq³ência; um estimador de erro de freq³ência para medir um erro estimado de clock de baixa freq³ência; e um controlador de repouso para remover a energia do gerador de sinal de clock pelo valor duração de repouso corrigido, desse modo economizando energia entre os slots de alerta designados. Durante o tempo "acordado", o sinal de clock de baixa freq³ência é resincronizado ao clock de alta freq³ência, desse modo corrigindo qualquer erro de freq³ência no clock de baixa potência menos acurado durante o modo de repouso.
