CRANE-100649
Current structures, such as armor, microelectronics, or critical infrastructure systems, lack effective, real-time sensing systems to detect event causing damage, such as impact from a ballistic object, tampering, physical impact, e.g., airborne or space debris, or other events that cause damage. Event causing damage may affect structural integrity, cause failure, and even threaten people's lives.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed, and patented an event detection system and device that detects events of interest such as damage events associated with impacts, interactions between structures, or structural integrity events. It contains input and output coupling points that have an electromagnetic signal generator connected to points. An electromagnetic signal measuring device that measures the electrical signal difference between input coupling point and output. It then has a processing system adapted to control the signal generator and measuring devices and the processing system is adapted to determine the date on damage events based on the changes between the input and output. It also includes an output device adapted to produce damage data, including a representation of damage alert, damage event location, and damage event origination axis.

Advantages:
-Structural perimeter information
-Armor integrity information
-Exemplary ballistic strike detection
-Estimation of a ballistic object's relative velocity, size, and location of impact

Potential Applications:
-Aircraft industry
-Commercial vehicle industry
-Space based systems
-Military
