Considering the structural features of floors, we partially raised the issue of sound insulation, but there are other ways to meet with fairly high insulation efficiency. One of the such method is the 'floating floor', whose idea is to 'harness' the floor on a layer of sound insulator. As an insulator, you can use rolls of mineral wool, expanded polystyrene sheets, mats and steklovatina etc. In this design the floor insulation is important that the 'floating' floor never touched home designs. To accomplish this mats laid on steklovatina trimmer joists at right angles to them. Using mats made of steklovatina, you need to carefully read the instructions on their use, since some of this material laying a backing paper down, and some – on the contrary. Particular attention should be paid device insulation between the walls and floor of the room. To do this, mats wrapped up so that they overlap in the subsequent baseboards.
By layer steklovatina or other insulating material installed lags the desired section, for which the subsequent finishing plank floor. Floor boards should be tightly pressed against the walls curved up ends. Feature of this flooring is that the lag is not nailed to the beams overlap, creating thus the floating structure. For convenience, you can lag at times pribit small nails, which are in the process of laying plank floor are removed. Gaps between the planks and the wall skirting close by nailing them to the floor, and not to wall. 'Floating' floor will provide a sufficiently reliable sound insulation, creating an apartment in comfort. The advantage of this method is that it is possible to avoid placing a heavy rolling, which should keep the weight of the soundproofing material. In this case, the ceiling can be made of light materials (drywall, Lining, etc.) that will not be loaded with a layer of insulation.
To speak on technology is in medias online or offline, never is easy task. As this niche seems to be always the front of what it foresees the users, is difficult to publish substances that are current in its content, since what it is newness in one week seems to be exceeded in the other. Blogs leaves in advantage in this race, because in contrast of the magazines, its posts can be made and be published quickly, informing its readers in the day and even though in the hour of a technological launching. However of launchings they are not only made blogs of technology, also has evaluations and new explanations of use products and services. These evaluations serve to assist, and until who it knows to influence the reader in the hour of its decisions. When one is about launchings of gagdets, design and other electronic products, few blogs if they approach to the ability of the Digital Drops (). Established in 2006, the success was reached with the simple form of speaking, that it prevents to use terms technician, because thus of it your self Interney (), that already it was pointed some times as blog more had access of Brazil. Blog is a success when it is about partnerships and accesses reason beyond speaking of technology, it deals with subjects that bind to the Internet the communication area, one of the specialties of Edney author Souza. As these blogs, you also can be a prominence of the Internet. For this it is necessary that you have devotion and creativity, two things that you already can go improving now, then he creates its now blog and he divulges its ideas for there. what you are waiting to stop falling of time in this net?
The inventor is David T. moment. The unusual idea was the following – the brake pedal after ignition immediately blocked, and to disable car alarm systems as required to keep the ignition key in the on position for 10 seconds. In the first half of the 80 radio channel unilateral signaling experienced the peak of its popularity. Since 1980 operation includes radio-controlled or "contactless" devices that can remotely disable the car alarm and unlock the car door. In this work based on the signaling technology rfid (Radio-Frequency Identification), rfid.
rfid – label is located in the key fob, containing a special series of code unique to each car, and could be more than 1 million possible combinations. These were the first steps of encryption rds. The code is a recurring 40-bit sequence. Pressing the button is disarmed, keyring sent radio 40-bit code, along with a team of automatic opening doors. If sent identification code passed, the car door unlocked.
In the future, this technology is widely used in contactless immobilizer. In the future expansion of functionality alarm systems provided by the inclusion in the protective range of different sensors. The situation changed dramatically after the two-level shock sensor, which can be set up "the force of impact on preventive and primary levels. In the next decade, many automotive giants (General Motors, DaimlerChrysler, Ford, etc.) included in the original equipment of their cars different staff security systems. Standard established immobilizers were installed on some European cars since the mid 80's. With the increase in the fleet around the world and the persistent rise in crime, increased the number of selling car alarms.
