Abstract
In a method for detecting free fall, a first acceleration parallel to a first axis, a second acceleration parallel to a second axis perpendicular to the first axis, and a third acceleration parallel to a third axis perpendicular to the first axis and to the second axis are measured. A sum of a first absolute value of the first acceleration, a second absolute value of the second acceleration, and a third absolute value of the third acceleration is calculated, and the free fall is detected as a function of the sum.
