The break signal state occurs when a transmission is suspended and the line is placed in a break state (all low, no stop bit) until released.

中断信号状态发生于传输暂停时，此时线路会置于中断状态(全部都低，没有停止位元)直到其释放为止。

Slip rings are utilized to realize the purpose of unlimited rotation, so as to avoid the signal line within the measuring arm to break down.

选用滑环结构以实现无限旋转的目的，从而避免了信号线在测量臂内部绞断的问题。

This type of tag, however, requires a buoy to carry the aerial, and this is attached to the shark by a ten-metre-long line. (The line is needed because the sharks themselves rarely break the surface, and the transmitter cannot signal to the satellite from under water.) Two American biologists, Scott Eckert and Brent Stewart, from the Hubbs-Sea World Research Institute in San Diego, have had some success with satellite tracking.
