초록

In a set of airbag igniters, each igniter has a mounting ring connected to and surrounding a portion of its body. Each igniter is supported in a retainer having an X-ray permeable wall surrounding the mounting ring. The mounting ring has a radially outwardly facing surface having a pattern of annular grooves hidden from visual inspection by the wall of the retainer. The pattern of grooves is the same for all of the igniters in the set having the same sensitivity, and any two igniters in the set having different sensitivities have different patterns of gr...
