Gate Barrier in UAE

One of the first electric gates was invented by a Canadian Fred W. Watson in 1881. It was designed to be used for railway systems. In 1884, a number of American newspapers reported that the French railway companies were about to adopt an electric gate opener. “A catch connected with an electro-magnet keeps a gate closed,” reported The National Tribune on October 9, 1884. One of the early demonstrations of such gates in the United States was arranged by the short-lived Toulmin Electric Railway Gate Company in 1887, in Baltimore. At the end of the XIX century electric gates were also used at horse racing tracks.

UAE

The UAE supported military operations by the US and other coalition nations engaged in the war against the Taliban in Afghanistan (2001) and Saddam Hussein in Ba'athist Iraq (2003) as well as operations supporting the Global War on terror for the Horn of Africa at Al Dhafra Air Base located outside of Abu Dhabi. The air base also supported Allied operations during the 1991 Persian Gulf War and Operation Northern Watch. The country had already signed a military defence agreement with the U.S. in 1994 and one with France in 1995. In January 2008, France and the UAE signed a deal allowing France to set up a permanent military base in the emirate of Abu Dhabi. The UAE joined international military operations in Libya in March 2011.
