First Claim
Patent Images
1. An electronic device, comprising:
- a first receiver configured to receive a first wireless signal;
a first timing module configured to wake up the first receiver from a first sleep state and to generate a synchronization signal indicating a wakeup time of the first receiver;
a second receiver configured to receive a second wireless signal; and
a second timing module configured to receive the synchronization signal and to wake up the second receiver from a second sleep state based on the synchronization signal.
