    SUMMARY:

    We will have Thomas Nichols from GM in to discuss the problem with counterfeit airbags. The agenda includes:

         1) Known Cases
         2) Composition and Performance of Genuine OEM Airbags
         3) Lab analysis of Counterfeit airbags and their deployment
         4) How to identify counterfeit airbags
         5) Resources & Support

    When Thomas is finished, Wade Bartlett will fill the remaining time with a discussion of how the system decides whether or not to fire an airbag:

    -It is a Predictive system - attempting to determine what's about to happen in the next 150ms based on the early part of the event

    -Acceleration Rate of Change is called JERK

    -Seatbelt status is (probably) taken into account

    -The idea that "bags deploy at some speed change" is WRONG...but here's why it got talked about that way.
