Most consumer AI products assume a live connection back to a server. Safety systems for defense, mining, and tunnel construction can't make that assumption — the environments they operate in are frequently disconnected by design, whether that's a soldier out of signal range or a crew several hundred metres underground.

That's why we process on the device itself. Edge AI means the model that detects physiological stress runs on the wearable or a local gateway, not in a data centre. It costs more engineering effort up front — model compression, power budgeting, on-device inference — but it's the only architecture that keeps working exactly when it's needed most: when everything else has gone offline.
