I have not seen these devices but I suppose it is an infrared transmitter that is requesting to open the door. Then the door is closing automatically.

If anyone can list the components needed to create one that would be nice. Also, does it use infrared?

You have a remote, that uses lights so you don't need a remote...Umm what? Can you restate your question more clearly so it makes more sense.

See my site. I do this thing. I meant not with the light.

Maybe you are talking about RFID technology.
What is RFID?

Some are blessed with the Holy grail of the mystical orb contained within the Secret decoder ring. I have accepted the fact that I must trudge along in life with simple mere mortal powers and try to deduce what is being asked. What we have here is a trial by error post. Perhaps if i gain enough Karma, the powers to be will bring me to Nirvana and the key to the ring will be found.

I think he wants a universal garage door opener like the ones built into newer cars. But of course he wants to know the science behind it!
