While the main gate is open, the conditioned input signal pulses are passed through to the counting register, where they are tallied and then scaled for output by the display circuitry.

当主控门打开时，经过转换的输入信号脉冲通过它进入计数寄存器，并在此统计，然后通过显示电路输出。

For example, memory circuit 515 can store configuration bits in a field programmable gate array, where one of the configuration bits is used to generate the select signal.

例如，存储器电路515可在现场可编程门阵列中存储配置位，其中一个配置位用于生成选择信号。

As attendants wait the signal to unlock and roll back the steel, passengers chomp a little bit. It's a mad dash once the gate is open.

检票员等待着信号准备开锁，收铁门，放行，乘客们咬着牙、卯足劲，因为一旦门开，就是疯狂的冲锋。

Hitachi is working with Nippon Signal and the University of Yamanachi to build a new boarding gate that hopefully kills those two security birds with one stone.

ENGADGET: Hitachi boarding gate can sniff explosives on passes, keep the transport queues flowing (video)
