Abstract (en)
[origin: WO9616376A1] Positional and/or movement information concerning a movable member (4) can be derived by using an implanted code pattern (17) which is implanted into a surface layer of the movable member (4). The code pattern (17) is selectively readable by a reader (9) which transmits signals to computer means (20) for calculation of the positional and/or movement information in relation to a given datum.
