Power Metrics
Charles Norona
In order to incorporate more electrical engineering aspects I have
uploaded a couple of screenshots of some power consumption metrics
acquired by the University of Michigan's PowerTutor (http://
powertutor.org/) application while the RIFL client application was
running on the phone. Unfortunately, it only tells us about LCD and
CPU power consumption (GPS and WIFI were not being used by the app).
We still need to find out how much power was being consumed by the
sensors and the Bluetooth radio. Both I think can be estimated based
off of the information from the appended datasheets:

We still need to find out more about the Bluetooth radio and how much
power it consumes during an RFCOMM streaming transmission.
