摘要：
A method for determining a distance between a first piece and a second piece includes measuring, at the first or second piece, a first signal at a first frequency, and measuring, at the first or second piece, a second signal at a second frequency. The second frequency is different from the first frequency. The distance is determined based on the measured first and second signals.
