Open the CIPO recordAbstract From the Canadian patent
A mechanical structure (100) comprises a moving mass (3) suspended by beams (4, 5, 6, 7) from a fixed frame (2). The structure (100) comprises elongation means (23-26) mechanically connected to each of the beams (4, 5, 6, 7). The elongation means is designed such that the stiffness of the beams (4 5, 6, 7), varies only little during movement of the moving mass. The structure is characterised in that the response of an elongation means is asymmetric when acting in tension and in compression. The structure is thus made insensitive to accelerations along a direction parallel to the suspension direction.

Why it's free to use
- Filed April 19, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 19, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 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.
