Abstract From the Canadian patent
A resistant initiator for an automobile passenger restraint system which includes a shell casing having an upper chamber and a lower chamber. Contact pins connect the initiator to a mating electrical connector of a vehicle. A metal oxide varistor disposed in the shell casing provides electrostatic discharge and EMI/RFI rotection for the initiator. A glass to metal seal header is formed in the shell casing and includes an integrated circuit for igniting the pyrotechnic material disposed in a charge holder attached to the shell casing.

Why it's free to use
- Filed April 3, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 3, 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.
