Open the CIPO recordAbstract From the Canadian patent
A position, orientation, shape and motion measuring tool is provided in the form of a flexible substrate with bend and twist sensors distributed along its surface at known intervals. A ribbon-type substrate is preferred. The geometric configuration of the substrate is calculated from inter-referencing the locations and orientations of the sensors based upon the detected bend and twist values. Suitable applications include motion capture for humans for use in animation, six degree of freedom input to a computer profile measurement , and location tracking within a large singularity-free working space.

Why it's free to use
- Filed March 17, 1998 and granted December 2, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 17, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 17, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
