Abstract From the Canadian patent
A device is provided for ignition of a pyrotechnic or hybrid inflator for use in motor vehicles by the input of energy provided by a laser source. The laser energy is conducted through an optical fibre and an optical window in the inflator housing where the ignition of a propellant initiator is triggered. This apparatus eliminates the potential for ignition of the inflator by radio frequency energy or static electricity acting on the electrical squib which is standardly used to ignite an inflator. This design further simplifies the igniter assembly for use in an inflator.

Why it's free to use
- Filed July 18, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 18, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 18, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
