Recently patented by Barbecan Security Systems, the LRD is a series of parallel hallways positioned at the entrance of a building. Each passage has two doors that move with you as you walk, temporarily closing both in front of and behind you — similar to a revolving door.
How to stop a determined gunman or suicide bomber? A robotic entrance portal or linear revolving door (LRD) could come in handy.
Recently patented by Barbecan Security Systems, the LRD is a series of parallel hallways positioned at the entrance of a building. Each passage has two doors that move with you as you walk, temporarily closing both in front of and behind you — similar to a revolving door. The portals are equipped with sensors to track the position and movement of people walking through. The portal robotically follows their pace as they walk; if the pedestrian walks quickly, the portal door panels move quickly; if they walk slowly, the portal operates slowly; if they stop, the portal stops. If the sensors detect a threat, like a hidden bomb or firearm, the doors move in reverse and push you out.
Operation is completely safe, and by adapting to the pace of pedestrian traffic, LRD portals can be used at high-traffic entrances, such as schools, malls, theaters, stadiums and factories. Portals can be stacked to offer even higher traffic rates, and direction is programmable to adjust to times when entrance or exit activity dominates.
Applications include:
● Schools, colleges and universities
● Shopping malls and theaters
● Banks
● Embassies, consulates and military bases
● Stadiums and conference halls
● Courthouses and government buildings
● Transportation (trains, underground/metro, buses and ferries)
● Airport entrances, customs and immigration checkpoints
● Airport Exit Lane Breach Control (one-way door without threat sensors)
● Hotels and Office Buildings
● Factories
Both US and international patent applications (PCT) have been filed for the LRD technology.
