Open the CIPO recordAbstract From the Canadian patent
A vehicle crash sensing system for making omnidirectional acceleration measurements comprises 1) an assembly (26) of at least three preferably selftestable accelerometers (10, 12, 14) mounted in an array on a substantially common plane (16) with axes (18, 20, 22) both skewed relative to one another and intersecting a region near a point and 2) an electronic control module , (30). The accelerometer signals (A B, C) provide a redundant measure of the associated acceleration vector (R). The magnitudes of components for associated acceleration basis vectors are calculated from the accelerometer signals (A, B, C) and used in the detection of crashes for associated safety restraint systems …

Why it's free to use
- Filed October 16, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 16, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
