Key Technologies

Technical Highlights

🔊

Low-Frequency Acoustic Modulation

Proprietary acoustic protocol optimized for underwater transmission. Uses frequency-shift keying (FSK) in the 20-40 kHz range for stable communication with minimal power consumption.

Energy-Efficient Signal Protocol

Adaptive transmission power based on distance and environmental conditions. Sleep modes and wake-on-signal reduce power consumption by 60% compared to continuous operation.

💧

Compact IP68 Waterproof Design

Multi-stage sealing with pressure-compensating membrane. Tested to 100 meters depth. Resistant to saltwater corrosion and thermal shock from rapid temperature changes.

🧠

Proprietary Sensor-Fusion Algorithm

Machine learning-enhanced data processing combines inputs from multiple sensors to filter noise and provide accurate real-time health metrics even during physical activity.
