Acoustic Presence Detection TRIZ Cases
- Gunshot Sensor Device Using Infrared and Acoustic Fusion
A gunshot sensor device combines mid-infrared motion detection with near-infrared buffering to identify acoustic events.
- Seismic Receiver Deployment via Aerial Delivery
Helicopter-based receiver deployment eliminates operator safety risks and environmental damage from trail clearing while maintaining high data density.
- Sonic Source Estimation via Antichain Length
Graph theory identifies longest antichain to estimate sonic sources, resolving reliability issues from location uncertainty.
