Abstract
This defensive publication describes a fully sealed, wireless coxswain audio communication system designed for rowing shells, eliminating all exposed electrical connectors commonly found in traditional cox box systems. The solution integrates a waterproof wearable headset with digital MEMS microphone(s), a Bluetooth LE Audio transmitter, and Qi-based inductive charging within a connector-free housing. A boat-mounted receiver/amplifier module wirelessly receives audio, drives existing speaker wiring, and supplies inductive power to portable components. An optional detachable user-interface module provides visual feedback, system control, and additional charge-sharing capability through wireless power exchange. The system architecture enables complete wireless communication among all user-handled components, reducing points of failure due to moisture ingress, cable fatigue, or corrosion. Integrated GNSS hardware and wireless telemetry provide real-time boat positioning, performance metrics, and stroke-related data without compromising environmental sealing. Variants include remote coach access, two-way audio communication, modular configuration of components, and support for rowing-specific sensors. All disclosed embodiments and combinations establish prior art for sealed, wire-free coxswain communication and telemetry systems with inductive power transfer and remote audio capabilities.
