The invention relates to a method for determining the position of a sensor element (300), according to which a magnetic alternating field (210) emitted by at least one field generating unit , (200) is measured. The position of the sensor element (300) is determined on the basis of a signal , received in the sensor element (300). The inventive method is further characterized in that , interference fields (410) are calculated preferably to a first approximation, said interference fields being caused by eddy currents (420) produced in electrically conductive objects (400). The , position that can be determined on the basis of the signal received in the sensor element (300) is , …

Why it's free to use
- Filed July 10, 2001 and granted March 12, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 10, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 10, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
