Abstract

A helmet testing apparatus including a movable member, a sensor coupled to the movable member and configured to acquire compliance data regarding a liner disposed within a shell of a helmet through engagement of the sensor with the liner, and a processing circuit configured to determine a rating for the helmet based on the compliance data and predetermined compliance parameters for the helmet.
