History of automatic doors

Although we normally connect automatic gates [ประตู รั้ว อัตโนมัติ, which is the term in Thai] as a sign of advancement in technology over the last few years, the suggestion of automated door opening has really been around for centuries. As a matter of fact, in the initial century AD, a Greek mathematician famously referred to as Heron of Alexandria was probably the very first ahead up with the principle of automatic doors. He called it equipment number 37 at the time.

His style suggestions behind this maker number 37 were straightforward but great. The arrangement was like this: As the priest with his churchgoers of fans would come close to the temple, the large doors would amazingly open on their own!

Really, he developed a clever mechanical setup underneath the church positioned in front of the large temple door. When the priest would step forward as well as light the fire on the church, the heat created would kick the counterweights, and pulley plan under it right into the action, which would subsequently unlock. Such an arrangement in those times was seen as a wonder. As an indication of the Gods being pleased with the priest, and after that, unlocking in acknowledgment of his solution!

Impressed by this mechanism, Heron of Alexandria wished to use this door opening technique beyond temples, yet it wasn’t truly effective.

It was many centuries later on, in 1931, when engineers Raymond, as well as Roby, created the idea for an automatic door for general objectives. They got their design patented and mounted the first automatic door-opening system in a Connecticut restaurant in the US. The resort staff was extensively amazed by this marvel of design. Stewards could walk around despite their hands being engaged with plates, as well as mugs and no longer required to awkwardly steer door,

Now, pertaining to modern computerized door systems, a lot of them include sensors that aid in activating the closing/opening of doors when needed. Let’s look at the different types of sensors used in automated doors.
