Claim 8:
9. The detection method according to claim 8,
wherein the generating of the one or more feature signals includes calculating a variance of the differential signal,
wherein the comparing of the one or more feature signals to the one or more respective feature threshold values includes comparing each value of the feature signal indicative of the variance with a threshold variance, and
wherein the determining of the contact signal as a function of the comparing of the one or more feature signals to the one or more feature threshold values includes:
setting the value of the contact signal equal to the second value in response to the feature signal being smaller than, or equal to, the threshold variance; and
setting the value of the contact signal equal to the first value in response to the feature signal being greater than the threshold variance.
