I get these signals from devices: 11110000000111111, but I need to get this: 1 .... 0 ...... 1 ....
Dots are the absence of a signal.
How can I replace a repeating signal with a single signal?
I made a circuit using a relay. When the first signal arrived at the relay, the relay switches itself off. Thus, I can turn several signals into one signal. But it only works once! How can I do it right?
For example, I want to control a door so that it opens and closes with a motion sensor. The problem is that the motion sensor sends a repeating signal. And if I do this with a repeated signal, then I cannot open the door manually. Because a repeated signal will not allow me to do this. So I need to convert it to a single signal. Please help me solve the problem.

You can put an auto door from item assembly, where motion detector is used, and look at how this door works.
I hope I understand the situation correctly and this will help you.

You can download my ship and copy over my automatic doors if you'd like... it's "The Dauntless" and the auto doors function flawlessly. It was a pain to figure out. The auto doors that come with vanilla, aren't exactly fully automatic and are slow. So i did mine from scratch and they definitely work and use motion sensors as you desire.
