▸创新点4：接口桥接IC设计实现了从低速控制信号（如CAN）到高速视频接口信号的宽范围接口信号转换，提升了系统的灵活性和集成度，同时优化了能量效率和面积效率。

Abstract

A 6 Gb/s 9.8 pJ/b rotatable non-contact connector applicable to industrial robot arms is developed. The proposed non-contact connector enables a high-speed and highly reliable wireless data connection between three-dimensional (3-D) cam- eras and an edge computer in an autonomously controlled robot. A rotatable transmission line coupler (RTLC) is proposed to accommodate the rotational operation of the robot arm. Since the proposed doughnut-shaped RTLC has a constant overlapped area at any rotati
