Abstract

An impact detection and remediation system includes a sensing device for detecting damage events related to a structure of interest. Such damage events may include impact from a ballistic object, a tamper event, a physical impact, or other events that may affect structural integrity or cause failure. Illustratively, the sensing device is in communication with a measurement system to determine impact criteria, and a processing system which is configured to use the impact criteria to determine a direction of the initiation point of a ballistic causing the damage event.
