galism 4:caab577334f0 2 Author: Michael Galis
galism 4:caab577334f0 3 This header file describes the Acceleration Service that I created to be able
galism 4:caab577334f0 4 to send the x, y, and z accelerations as the bicycle is moving. These
galism 4:caab577334f0 5 accelerations will be used by the phone to calculate the speed of the bicycle.
