The team used a trick called “pipelining” in which sensors acted as message-passing relays for other nearby sensors.

这支团队玩起一个名叫“流水线”的把戏，让传感器扮演信息传递员的角色把信息传到另外那些在附近的传感器中。

Before shutting down each night, the rovers send pictures and other data of their positions to an orbiter called Mars Odyssey, which relays them back to mission control.

Other CARDS, such as the Model 7700 20-channel Differential Multiplexer Module, use latching relays, and the offset voltage is the same whether the poles are used as a single pole or as a pair.

其它开关卡，例如7700型20通道差分复用模块，采用的是闭锁型继电器，无论是成对还是单独使用一个闸刀，偏移电压都是相同的。

Yet as UAV technology improves they are set to become an even more important part of security and military operations -- part of a system that gathers and relays information to other drones, ground control, manned aircraft and satellites.
