AI Technical Summary

Technical Problem

Existing data transmission technologies in vehicle interiors, particularly aircraft, face challenges with LiFi due to obstacles blocking light signals and the need for separate installation of LiFi and ToF sensors, leading to space constraints and increased costs.

Method used

A combined LiFi and ToF data transmission unit using a common light source module and control unit to ensure compact installation and efficient obstacle detection, allowing for reliable high-speed data transmission by switching between LiFi units when obstacles are detected.

Benefits of technology

The combined unit reduces space and manufacturing costs while ensuring uninterrupted data transmission by detecting and adapting to obstacles, maintaining high data rates through path monitoring and efficient signal management.
