Abstract

Describes a patent application for the sensing component of an after-market automated emergency-call response system for vehicles that have been in a crash that involved an air bag deployment. The systems are usually tied into the car�s electrical system and are triggered by activation of the air bag. For after-market applications, an acoustical method is proposed that will identify air bag deployment and provide the needed trigger to the emergency call system. The acoustical method relies on both sound level and spectral shape to recognize the acoustical event associated with air bag deployment.
