System and methods of reducing energy consumption by synchronizing sensors

A computing device, comprising:

• a first sensor including or coupled to a first sensor clock;
• and
• a processor including or coupled to a processor clock to:
• correct the first sensor clock for a first time,
• transfer data from the first sensor, and
• correct the first sensor clock for a second time,
• wherein a time interval between the two corrections of the first sensor clock is selected such that the first sensor clock is sufficiently aligned with the processor clock over the time interval, and wherein the correction of the first sensor clock comprises:
• receiving information related to the processor clock;
• deriving a clock correction factor;
• and
• applying the clock correction factor.

A computing device, comprising:

• means for correcting a first sensor clock of a first sensor for a first time;
• means for transferring data from the first sensor;
• and
• means for correcting the first sensor clock for a second time,
• wherein a time interval between the two corrections of the first sensor clock is selected such that the first sensor clock is sufficiently aligned with a processor clock of a processor over the time interval, and wherein the means for correcting the first sensor clock further comprises:
• means for receiving information related to the processor clock;
• means for deriving a clock correction factor;
• and
• means for applying the clock correction factor.

A non-transitory computer-readable medium including code which, when executed by a processor, causes the processor to perform a method comprising:

• correcting a first sensor clock of a first sensor for a first time;
• transferring data from the first sensor;
• and
• correcting the first sensor clock for a second time,
• wherein a time interval between the two corrections of the first sensor clock is selected such that the first sensor clock is sufficiently aligned with a processor clock of the processor over the time interval, and wherein code for correcting the first sensor clock further comprises code for:
• receiving information related to the processor clock;
• deriving a clock correction factor;
• and
• applying the clock correction factor.
