Farshid, why do you calculate "2" to the power of "g"??

Think of an accleration sensor of a device containing a small reference mass "m" connected to a "spring", where the force acting on the mass (F = m x a) is determined by measuring the elongation of spring (Hook's law). As the reference mass is constant the elongation of spring is a direct measure of acceleration "a", where "a" is the sum of the "parallel" component of gravitational acceleration "g" and additional accelerations like tangential and centripetal acceleration. Everything then is self explaining.
