一种多光束传感系统，具有脉冲光源、多个光传感器和响应于每个传感器的数字电路，以检测对任何传感器的光的中断。一个数字检测器电路使用AND门；另一个具有一系列双稳态电路，通过来自传感器的脉冲在稳定状态之间启动。只要波束没有断裂，输出信号就存在。一个波束的中断或任何部件的故障由输出信号的损失来表示。
A multiple light beam sensing system with pulsed light sources, plural light sensors and a digital circuit responsive to each of the sensors to detect the interruption of light to any sensor. One digital detector circuit uses an AND gate; and another has a series of bistable circuits actuated between stable states by pulses from the sensors. An output signal is present so long as no beam is broken. The interruption of one beam or the failure of any component is indicated by the loss of the output signal.
