The idea of making the building 'intelligent' originated in the United States. First appeared Intelligence building (intelligent buildings), which were based on the use of structured cabling systems. Such systems allow using the same cable to provide job exchanges, computer network, security, etc. Then the system began to emerge multiplexed communication channels, allowing a single cable to transmit a variety of information simultaneously. The concept of smart home has been formulated in the 70s of the 20th century by the Institute of Intelligent Building in Washington as 'Building, providing a productive and efficient use of space.

Further searches for ways to improve the automation and creation of new solutions captured many electronic company. To date there are over ...  Read the rest of the entry...

The first polyurethane foam invented (created) by Otto Bayer in 1947. First, polyurethanes have been used in industry as insulating boards, but in the seventies came the technological breakthrough in chemistry and began widespread use of polyurethane foam in aerosol (PUR). The first company packaged in a foam container was an English Royal Chemical Industry, but the first country, who used the foam in the construction, was Sweden - it happened at the beginning eighties, so that today the foam is a young and building products. Polyurethane foam in industry and construction for the production of modern foam need innovative recipe and product quality. A key indicator of success is the development of the Division of Research and Development appropriate chemical formulations, as well as overall quality control during production process. The consumer is required to use the goods in accordance with manufacturer's instructions on the label. (Similarly see: Xcel Energy). Polyurethane foam - is a special product. Xcel Energy recognizes the significance of this. The foam is an excellent placeholder for the various voids and cracks and has good sound and heat insulation properties (1 santimmetr hardened foam on its properties correspond termichnym 1.4-1.8 cm polystyrene or mineral ...  Read the rest of the entry...

Quite often in cases where breaks or laptop computer from its owner raises two important questions: 1. Actually who will repair? 2. How expensive will this event cost? At the same time only a small part user thinks, because of what computer technology slomalas.A because this particular question will be no less weighty than those to whom it is difficult to order an expensive computer equipment repair, and how much it will appropriate repairs. Of course, no conclusion drawn by a professional regarding the reasons for failure, the average user to understand the reasons, it is very difficult. Whichever PC or laptop represents a serious device, which consists of all parts and components, so you should be aware that, in general, its performance depends on proper and, certainly, careful operation. By the failure of the personal computer or laptop can push: mechanical impact on him, water, dust accumulation inside the system unit. In addition to these fundamental reasons, almost any break computer or disturb its very condition are quite capable of incorrect settings of systems implemented by the user, including installed software. For example, when buying a computer game should always be listed on the package to compare the system ...  Read the rest of the entry...
