14. A computer-implemented method comprising:

sending, from a first processor in an apparatus to a second processor in the apparatus, a first set of instructions;

sending, from the second processor to the first processor, a first signal to direct the first processor to deactivate;

setting a first timer to a first time interval;

transitioning the second processor to a sleep mode for the first time interval, wherein the sleep mode consumes less electrical power than a wake mode;

determining the first timer has expired;

transitioning the second processor from the sleep mode to the wake mode;

acquiring, using the second processor, sensor data from one or more sensors of the apparatus;

determining, using the second processor, that the sensor data is to be sent to an external device;

sending, from the second processor to the first processor, a second signal to direct the first processor to activate;

sending the sensor data from the second processor to the first processor;

receiving, at the first processor, the sensor data; and
