It called the Linear Revolving Door (LRD), and it was recently patented by Barbecan Security Systems. The door consists of series of parallel hallways that can be built at the entrance of buildings. Each hallway has two doors that revolve in front of and behind a person as they enter.

Once both doors close, sensors also check for bombs or firearms. If a threat is detected, the doors move in reverse and push out the potential offender.

If you read the article, the company creating this are implying that it could replace armed guards, who potentially might not be able to stop an armed intruder. So I would think this would be marketed to schools and other businesses.

Agreed, replaced was a poor choice of words on my part.
Still, what I like the most is people thinking in a different direction. Not just focusing on guns, you know?

You can design a sensor that can tell the difference between a gun and a steel toed shoe. Most places wouldn't use it because the cost is prohibitive right now. But a high security, high traffic area would be a great place to put something like this.

You can design sensors that will detect certain shapes. You match those shapes to weapon components, and it will detect those. I've seen sensors that an detect a gun in the middle of a load of freight on a semi-truck, and others that can detect individual components. You might not be 100% on the components if they're disassembled, but you set it to kick them out, and then you only have to have one guard, to check them, or you have the police arrive and check them to be sure.
