Abstract
Upon impact, a ball is released and radially displaced into an annular space of decreasing thickness. Simultaneously, the ball releases a fluid to an absorbent material. The direction and distance of displacement indicate the direction and magnitude of the impact, and the subsequent migration of the fluid in the absorbent material indicates the elapsed time since the impact.
