S.T Prime Engineering Solutions' NOAH system utilizes a computer vision algorithm that learns its surroundings and detects drowning, complemented by a module grid that covers the pool floor. Once the system detects drowning, it issues an alert, and after a set period of time, it will release the most appropriate module to rescue and draw the drowning swimmer safely above the water's surface. The system can operate in either semi- or fully automated modes, using a screen interface for the pool owner or lifeguard.
