WebSled systems have demonstrated their usefulness in reproducing a given vehicle deceleration pulse in a controlled, reproducible manner. In a similar way, a toepan or floorpan pulse can be used to define the intrusion event. Analogous to the crash pulse used to characterize vehicle and sled tests, Kuppa and Morgan (1993) have suggested the use Webthis AC.
