Appeal to automatize technology has turned, in the life of the contemporary people, as important as food. Accepted or not, beyond what the enemies of this reality will say, this technology increase the efficiency of any action or procedure. In this article we prepare to treat the topic as how the modern technology has been able to apply his favors to – neither more nor less -important thing; the door. We will conclude the capability and the various options that all type of automatic gate opener presents. The gates are, basically everywhere. Nevertheless, not so clearly anymore, all the gates/gates are not the same. It is not the same to install a door/gate that is known they are going to pass thru thousands of people every day, to install the door of a small dwelling. Each door is, actually, as everything, to a specific case. And it is so, from the already above mentioned thing, preceding to every item of an automatic gate in specific, that we’ll like to show what the basic requisites are to think about the installation of an automatic gate. It will be seen that, actually, the conclusion of this problem is a very simple thing: The installation of an automatic gate is only justified in pros of, first, the need to improve the traffic of people (with or without vehicles) to a certain place, or second, the need to maximize the security. This way, to sum up, the type of gates that we talk about exist, basically, to guarantee the good circulation and the security of people. Let’s see every case. – Garage Automatic Doors: It is the most widely spread use of the technology that we treat. It’s application is already, in almost the whole world, a clear need. The reasons that justify having a automatic garage door are simple; the better circulation and safety. Nobody will deny that, in a day of heavy rain for example, getting off the car to open the garage door constitutes a real inconvenience. The installation of this type of automatic door eliminates from its roots this problematic scenario. By pressing a button the garage automatic door will open “ by itself ” and you’ll only have to park your vehicle. For what it does to the safety factor it is , perhaps much better. Having to descend from the automobile to open manually the garage door implies being vulnerable to a possible attacker’s action. Nothing of that will happens with an automatic door opener installed; using different technologies (that will be discuss later on) you will be able to open and close the garage gate without having to stop driving. The options that the market offers nowadays for this type of gates are innumerable. Both the aesthetic thing and the functional one are perfectly respected values in this type of installation. -Automatic industrial doors: It’s application is paradigmatic in the huge factories and platforms of load. They allow a better transit, in addition to the workers and chauffeurs, of the totality of the raw materials and goods, speeding and enhancing the logistic of any space of industrial production. They are, from the newly above mentioned thing, an impassable necessity of the sector. – Commercial automatic doors: The automatic gates of the commercial title are, first of all, linked with the need to improve the circulation of the clients. We do recount to this business, galleries or shopping malls that are visited everyday by a multitude. The most common of all options is that one who has a sensor; so when the customer approaches the door, it is acknowledge by the proximity and engage the mechanism to open, once the customer has gone away, and if no one else is prepare to enter or to go out anymore, the gate closes automatically. But automatic doors openers are not, at this point of technological evolution, any type of innovation. For the closure of the present article we want to announce some technologies (already present on the market) that constitute clearly an interesting innovation. -Automatic gates activation thru cell phone: It is very simple; instead of support and preserve a specific remote control for the garage gate, we are provided with the possibility of command the same door by means of a message SMS (in the one that is necessary to include a key). Beyond this functional peculiarity, the type of garage gates in question offers major safety; if it is opened of illicit form, you will receive a message of alert in his phone. -Fingerprint activated automatic gates openers: Ironically, modern society keeps on handling (as it did hundreds of years ago) with the use of keys? Well; with this type of technology the key has gone definitively to the history. Only it is necessary to place the a finger on a sensor especially destined and voila!; the door recognizes (or not) to the person. Not more problems of losing the key, of having fear of giving them to our children. With the new discoveries of today electronics we can think of voice recognition, biometrics and any other more secure ways to activate our doors which are not available (for the moment) on the market.
