How much do you pay for your apartment’s security now? Or may be you are still afraid of its’ safe guarding when going for holiday!? And how much cost the baby-sitter services? May be you’ve already thought of security officer for your child? Yes, of course without you all is going topsy-turvy! And what is the price of the intellect which everything keeps under control? But firstly let’s investigate what do you understand under the definition of “intellectual building”? Today the market offers you a unique chance to know about it practically! You will be able to manage your home with the help of elegant touch control panel or a universal remote control which will substitute the great number of panels from different devices, for example from TVs, DVDs, tuners, air-conditioners, boomchair, home theatre seating etc. The system “clever home” will allow gather the whole equipment in versatile entertaining system. The home automatically will make ready your movie theatre for film watching: will install the necessary parameters of illumination, pull down the screen, switch on the projector, adjust the sound and even keep up the necessary air temperature throughout the film watching. Your apartment or house will become your “clever” friend: it will pick up shutters tomorrow, switch on your favourite music or TV program, for example, on news channel, switch on air-conditioners or open the windows. In the evening your “intellectual friend” will fill your bath with water of needed temperature, add foam or bath salt, light candles and will create cozy atmosphere. It will even heat up supper if you want and will meet you with illuminated pavement to the garage. Do you like to surprise? Then make a party and meet your guests with illuminated path and various many-colored splashes of fountains. But for what you need it all if you enter your movie theatre only once a week, and you have no time for music tomorrow and for friends in the evening?

Then let’s talk about serious questions, for example about the protection of your home. Of course no security system can protect your children from troubles on the street. This is life. But anyway we have to admit that our home is our stronghold. You always will be in the awareness of what is going on in the home at the moment while you are in absence.

Sometimes the answers are close to us we just don’t want to try! I recommend you always to train yourself, improve yourself, speed to perfectness.

Today our life is integrated with such great achievements of science and high technology as plasma TVs, DVDs, internet, radio etc. But almost nobody ask himself about how the humanity had achieved such high results! We got accustomed to use TV as it is imprescriptible part of our life. However sometimes we need to know something more about TVs than just the date of its invention. Television is a part of our everyday life, but when was the first television made? And by whom it was made? Sometimes we all wonder what life would be like without the technological devices and services to which we have grown accustomed. Television is like that. Before the invention of television and the widespread availability of it, news and entertainment was only available by listening to the radio or going to the movies or reading a book. That was a wonderful life, is not it? People had chances to read books and know authentic stories not that cinematized today with great changes. But anyway we are glad to have TVs. So, let’s find out when was the first television made?

Development of the Television

What had given the push to the appearance of the first TV? Of course the development of the cathode ray tube (CRT) which was the main and central part of the first TVs. But how it had been working? The process seemed to be very simple. The image on the screen is the product of an electron beam that flows over the surface of the tube. The electrons strike the surface of the tube and as a result a bright pulse of light is emitted on the screen. The signal fed to the input of the electron beam determines what is seen on the CRT. Who had given the birth of a television device? It was a very clever young high school student who had envisioned a television. His name was Philo Farnsworth. At the age of fifteen he was admitted to Brigham Young University but with no long stay there because of some family troubles. At the age of 21 Philo began to file patents on various spheres of his invention (he was fond of studying physics and mathematics during school years). That time he and his wife were living in California. At the same time another outstanding scientist from Russia (he was an immigrant) – Vladimir Zworykin had been trying to develop the ideas of how to make a television system. He designed the system in drawings. They were so-called competitors. But Philo had one significant advantage. He had built and demonstrated his invention to the press in 1928 while Vladimir Zworykin had his ideas in theory only. It appears that Philo had passed ahead of the Russian. When the Second World War came the progress was halted. After the war, the time limit on the patents had almost expired. As soon as their time limit had expired, RCA quickly bought them and proceeded with their development for the open market. They had cheated Philo out of his share of the royalties.

The First Television Network

The first television network was established in 1928 in Germany. By 1936, the Olympic Games were broadcasted in Leipzig and Berlin and citizens could view the games in their hometowns. Since that time the television has been influencing on society. Around the world people began to get information about the latest news and to entertain staying home by using television. Exactly since that time the first ideas about TV stands and other entertainment furniture like wall units and theatre sitting has been appearing. There is one interesting fact – according to official statistics of Japan Japanese watches a TV 9 hours per day in average. After we have discovered the information about the time the first prototype of contemporary television was made we are to know who had invented it?

Who Invented the TV?

This is the big question! May be it could be a big big question for majority of us if there were not an internet in almost every home today! Thanks to all-powerful and omniscient world wide web which enriches our wit every time we are in internet! But this was little lyrical digression from the main and very important question to be more precisely – who invented the TV! Ok, I know that you can find all information in internet! But, listen, why to waste time on things which are spread all over the global web through sites if you can just find everything concerning the TV invention in one document!? And again it was little lyrical digression from the theme! I promise it never repeat again during this article!

In the late 1800s, images were able to be electronically transmitted using early fax machines. For example, images were able to be transmitted across the pantelegraph. In 1878, the earliest concept of the television was suggested – the idea of electronically transmitted images that were in motion. This idea was sketched under the title “telephonoscope.”

And now the very moment you have been waiting for since the beginning of this article! It was Paul Gottlieb Nipkow who in 1884 patented the first electromechanical television system with a scanning disk. This scanning disk was a spinning disk that had a number of holes that allowed rasterization. At this moment you are probably asking yourself what is rasterization? Rasterization was the process by which a visual image was converted into electrical pulses. When an image was captured by this rotating disk, each hole captured a portion of the whole image. This design became important to the development of the television.  When Nipkow first patented the invention, it was manly used to transmit halftone images.

How the process of advancements in technology has been taking its pace through the 20-th century?

The development of the television truly began to take shape in the twenties. John Logie Baird was the person who demonstrated his abilities in transmitting the image of a silhouette, the images of moving, monochromatic pictures in 1925. Now I’ll try to explain in simple words why he could do it! The scanning disk of John was able to show an image of thirty lines resolution which was a great technological breakthrough that times because this resolution was just clear enough to discern certain details of the image. But the image could only be transmitted due to “high” resolution of the scanning disk but also due to usage of a double spiral lenses. Once a very talented engineer had appeared in 1926 – it was Kalman Tihanyi. I know that the names of many people who had deposited their skills and intelligence in the development of high technology may be unknown for you! But it is time to know the “science hero” by sight in the end! That very talented engineer whose name was Kalman created the design for a television system that used electronic scanning and display elements. Actually, he could use the idea of charge storage in his design. This idea was realized by him within the scanning tube. The 1927 became a threshold between the pro-television era and the of age “TV rule”. In 1927, Leon Theremin invented a mirror-drum television system. This system used the concept of interlacing and was able to display an image resolution of one hundred lines. Imagine, just two years before that a thirty line resolution system was invented! Do you feel how the humanity develops fast? This tendency can be observed through the whole history. And the more we were brought closer to the present times the faster the mankind has been growing!

The same year of 1927 had shown us another outstanding person – Herbert E. Ives. He is known for its achievement in transmission a moving image across a cable between Washington D.C. and New York City. That was the great day! The one out of many when the cable system showed its great capabilities! Herbert used a fifty-aperture disc for the transmission, and the transmission operated at the speed of sixteen frames for every sixty seconds. It is worth to point out that the sizes of the screens that he transmitted to were about twenty-four by thirty inches – very small! He was then able to transmit a moving image using the radio from New Jersey. Many genius people had invested their skills to the TV system development, but as a rule there is one person who is granted for the merits! In 1927, Philo Farnsworth created the first working television system that was able to electronically scan images into it and then display the images. Farnsworth success was demonstrated to the press in 1928.

What Were the Names Given to the First Televisions?

When TVs were first displayed to the public they were called “Image Dissectors”. There was another name for TVs not less funny – “Radio with Pictures”! Exactly such simple and primitive forms got the names of first televisions. Today we can only wonder why people of the first half of the 20 century had been thinking in such primitive way! Though it is apparent! That time the humanity was at the 3-rd stage of the technological setup! Thus grandparents of our parents or even grandparents could not imagine that the humankind can develop in such fast speed! However It took a long time for early televisions to become mainstream and it was decades from the time of their invention until they became a regular in most homes.

In home interior by means of wall units it is possible to reach several goals at once. Such kind of furniture not only organizes the space and make it stylish but also improve it as of ergonomics. All necessary things including TV and technical gadgets can be compactly placed in one linear wall unit (along one side of the wall).

Such kind of furniture can be installed even along wall with a window or doorway. It can be used not only in living room but also in children room.

One wall unit for two

One children room for two children is not rarity today. But having great desire you can single out individual space for each child even in small room. In order to separate one space for two children you can use the following variant. From the one side of linear wall unit set one bad for one child, from the other side – for the second child. The wall unit is divided for two parts according to children. By the way the doors of one part are to be opened from one side while the doors of the second part from the other side.

Today the system of Ancient China which is known as Feng Shui is very popular due to its effectiveness with its doctrine of harmony in the world of animate and inanimate things. According to Feng Shui disorder in house is inadmissible and intolerable. All things should be in order and keep appropriate place in home. Chaos in the house leads to failures in ones life, problems with health and finance. The doctrine also concerns the choice and placement of furniture and the wall units as well.

The material for wall unit

While choosing a wall unit we often take close consideration to the material from which it is made. The Feng Shui advises to look at this question from a little bit different point of view. Because when we choose the material we orientate on different qualities: ecological compatibility, longevity and price. The Chinese doctrine determines that each object has its own energetic and the furniture as well has. In turn the energetic depends on the material from which the thing is produced. And so the furniture can influence the state of health by its energetic it is very important for us that this influence would be positive. In terms of Feng Shui we should give preferences to wall units which are from natural wood, because the wood vey well transacts through the positive energy. The most positive influence on us has the furniture from coniferous, for example from pine tree. Synthetic material for furniture is not preferable.  Generally wood races do have different feature that is why they are used for various purposes.  For example, wall units of dark wood are more proper to use in office rooms but light color wood for making cozy, home and trustful atmosphere.

Dimensions and form has great importance

Regarding to Feng Shui doctrine overall dimensions of wall unit and its proportionality to the room size are very important. If in case the room is too much blocked up with furniture it will cut off the way for positive energetic. Cumbersome and disproportionate furniture will oppress everybody in the room.

As regards the wall unit’s form the Feng Shui calls to use furniture with rounded borders and smooth lines. The reason of that is in simple interpretation: the most popular forms in nature are those with smooth lines. So we need to be as close to nature as possible.

Furniture functionality

According To Feng Shui the furniture should be in good order. If for example your wall unit has many years since you’ve bought it and it is partially in defective condition then it depress you and take energetic from you. Therefore it is not recommended to save this furniture. You are to get rid of such kind of furniture without feeling sorry. It is necessary to renew your home interior, making it more fresh and harmonious. The more functions the wall unit has the better it is.

The place for wall unit

It is worth to consider that you can’t make obstacles from a wall unit because the positive energy must freely circulate. It will be better if cupboards and other furniture units will have legs (the height does not matter) because in this case furniture standing on the floor will neutralize energetic of people living there. As wall units are often placed along walls you should remember that it is better to avoid perfect conformity of the furniture to the wall in order not to prevent energy to circulate. Following these simple rules of wall unit placement you will have good humour, success, prosperity and health living in your home.

By means of wall unit it is possible to create amazing atmosphere in any living area. Depending on the style such kind of furniture will suit as for ordinary accommodation so as for luxury country house. It being known that since having a wall unit you can be sure that since this time all your things will be in proper place in right order. Capaciousness and multi-functionality are the main advantages of wall units which are at the same time very compact. Talking about constructional features it is worth to accentuate that wall units are in two types: multi-sectional and single-sectional. The wall units which are of the first type are usually purchased for large rooms. Their advantage is in possibility to transpose separate sections. Single-sectional wall units usually have short length because of that they are oriented for short pier. Wall units have numerous advantages so it is hard to imagine how it is possible to combine them all in one set. In order to look into this question let us classify and make up all elements:

Thus contemporary wall units are of following elements:

-  Panels (side, lower and top). They are put into frame elements of design of the wall unit;

-  Patch. They can be made of glass, mirror, panel, or of several different material at once. The mirror patch look the most impressively, moreover they visually enlarge the area, improve the lighting. In glass patch the transparent, tinted, colored or stained-glass window can be used:

-  Shelves. They can be demountable or fixed. The first type shelves usually can be regulated by the height. It is very comfortable. For example in bookcase with demountable shelves it is possible to adjust the height so filling them with publications of diverse sizes. They can be produced of the same material as the wall unit is produced and so as from high-tensile glass. But these shelves don’t harden the whole construction. As opposite to this fixed shelves are elements which strengthen the construction of the wall unit. According to this fact, it is easy to keep off the diagonal warp of the frame. Fixed shelves are often produced of the same material as the whole frame;

Drawers. Standard drawers consist of shell (front, rear part and side part), façade (front decorative wall), bottom and rails (different types).

It is not difficult to suspect the thing first came to your mind after you’ve read the title of this article! Possibly you’ve decided that to choose an entertainment center is very easy work. However, as you’ve guessed we won’t start this talk if it is too easy task! With every season going by it becomes more difficult to choose furniture and especially the entertainment center, because today the supply and choice are great and we can’t concentrate on definite items we really need. As options and features are added to entertainment centers the process of buying becomes more complicated. Exactly for this reason you are to follow some advice given here in this little article. It will be your guide to the world of entertainment centers! Ready? Here we go!  The most important thing you can do before shopping for an entertainment center is take measurements. The measurements of the space where you plan to put the piece and the dimensions of the doorway through which the complete piece will be moved. The measurements of the DVD player or VCR, any stereo equipment, and any game systems will be vital to the entertainment center you are going to acquire. Then you are to consider what you need to store in your entertainment center. As additional options like shelves and cabinets nowadays are the integral part of entertainment centers of new generation you have chance to put special things such as remote controls, movies, instruction manuals, and books there. Only after having considered the sizes you can think of the type of design of an entertainment center. Styles of entertainment centers range from the simple traditional look, to the quaint country design, to the sleek contemporary style. You may also want to consider examining the entertainment center for the quality of the wood and construction. Many less expensive models are made of pressed wood. While these models are much more affordable and will likely last several years, they may not have the durability to last a lifetime or withstand frequent moves. That is why you should to choose an entertainment center constructed mainly of solid woods or veneers. The furniture from durable material such as expensive wood can stand the test of time. Also the veneer is the use of thin pieces of wood glued over a substrate. Veneered wood doesn’t expand and contract as much as solid wood, so it is less likely to be damaged when exposed to varying temperatures and humidity. But the damage made upon veneered furniture can lead to big expenditures as it is very expensive to repair. Veneer is generally less expensive than solid wood. Solid wood furniture is strong and durable and easy to repair, but it is more susceptible to environmental changes, expanding when the air is moist and contracting when the air is dry. Because of this, solid wood pieces may eventually show shrinkage or even split.

There are two main types of buying the entertainment center: already assembled and the one you should assemble yourself at home. Of course it is better to use the services of special shops where the entertainment center is sold. But it will cost much more less in cash that is why, it’s best to assemble your entertainment center in the room in which it will be used. Whatever entertainment center you choose, take a good look at the floor model that represents the piece you will be getting.

As today more and more questions rises upon the problem of space saving functions of furniture it becomes more obvious that we are to discover some ways of how to reach the desired result. That is why here we will try to give all necessary information you will need when buying home furniture!

A computer desk needs ample surface space.

One of the most popular ways to save space in your living area today is to take advantage from the combination of a wall unit with functions of a computer desk with a television stand. This striking method of hybrid furniture also gives a chance to integrate technology in a living room, media room or space-starved dorm room. TV and desk wall units need to combine all the necessary elements of a desk and a TV stand to be both functional and attractive.  There is another way to save space: you can mount your TV on a wall and to construct your own computer desk with maximum of comfort and minimum excessive elements! Moreover if in case your living area is too small and don’t let to place too much furniture even the most necessary you can equip your room with different functional zones. Each of zones will represent the special room. All these zones can be separated by means of dividers!

TV Wall Mount

One advantage of combining a TV wall unit with a desk is the elimination of another unnecessary screen. You can also use one screen for two purposes: for a TV and for a monitor of a computer! It will save the space two times more than 2 monitors! Computer users can use the same large screen that TV viewers watch from across the room. However, a wall unit has limited surface space and even a slim-profile TV can take up valuable space. There is a way of hanging the television above the desktop with the help of a wall mount. Having chosen this way you’ll have one very superb advantage for your health: the screen will be closer to eye level, which is ideal for computer users. If in case the viewer is sitting in a lower position (in a couch or chair) or at a greater distance across the room it will be perfect to raise the television screen above desktop items, like a keyboard, mouse or printer.

Shelving Surround

It is very usual that computer peripherals, printer paper, DVDs, CDs and other items take too much space for file and equipment storage and in order to save space we can use flexible storage space, such as adjustable-height shelves and cabinets large enough to accommodate organizers, bins and hanging files. You can surely accord that the more a wall unit with TV options and computer desk options has the more things we can arrange on it and correspondingly more space we will save.

Wireless Peripherals

Today we know that wireless devices eliminate the clutter that comes from cords in most media centers. So for this reason we can use this technology to avoid the overwhelming of the room with wires, adapters and various connections.

How do you think, whether it is possible to combine an entertainment center with a fireplace in one place? If your answer is negative you should read this article, and if your answer is positive then you should read this article as well! Because here we will discuss questions concerning the placement of shelf over a fireplace and an entertainment center in one! Let us start! There some instructions in a way of rules which will instruct you!

Instructions

First of all you should acquire the things you’ll need to build in a shelf over a fireplace: 3/4 plywood, 3/4 flat moulding, 1 1/2 lattice, 2 1/2 screws,  spackling, paint, sand paper. The first thing you will need to do is measure the hole that you will be applying the plywood for the shelf. You do not have to measure this exact and it would be better if you actually cut it about 1/4″ shorter than what it measures so that it will go in place easily. You will need to cut a 3″ by 3″ hole in the middle of the shelf at the back to allow for wires to go through. Once you have your measurements go ahead and cut the piece of plywood for the shelf. You will need to make sure that it slides in place pretty easy before you paint it. Once it is fitting good apply the first coat of paint and let dry while working on the rest of the shelf. You will need to cut 4 pieces of plywood about 4 to 5 inches wide depending on how tall you want the hole in the shelf to allow for other entertainment equipment. You will need a piece for the back wall and both side walls of the entertainment center. You will also need a piece for the middle support. Start with the back piece and for the article we will assume that it is 5″ wide. You will need to measure and cut the back piece again you can cut this a little short so that it slides in easily. With the back piece in place measure and cut the two side pieces. Next you will need to cut a piece for the middle support, you will need to cut this piece about 4 inches shorter than it measures so you will have room to run wires from one side to the other. Apply paint to all the pieces and allow to dry. Next you will install the back and side with 2 1/2″ screws. 1 screw in every stud should be sufficient. Next install the shelf on top of the pieces and attach to the sides with screws. Next you will want to install center support. Make sure you measure to make sure it is in the dead center and then attach to top with screws. Next you will need to put the 3/4 moulding on if the front of plywood shelf and the support. After that lay the 1 1/2″ moulding around the perimeter of the top to dress it up a little and to cover up all the screws. Use spackling to fill in any deficiencies in the plywood before painting. Once all the pieces are together you will need to add a coat of paint and touch up any blemishes with the spackling. Enjoy!

To hook up the surround sound in proper way you need to find out and decide what focal point will be the best to place television and speakers in the room. To have good digital entertainment centers supposes not only the acquisition of home theatre and its essential units but also wise placing of all those gadgets in order to enjoy the whole entertainment atmosphere with your favourite movie or music. If in case you have decided not to use the help of special technicians, you should take in mind that there will be exigency to consider some basic guidelines of sound management.

You should keep in mind that the room where the TV is to be placed needs to be an area that receives the least amount of outside light. Also make sure that the room is big enough for the sound system to be set up in. For this reason it is better to note down the length and width of the room and to place the TV right at the center. This will let you to position the speakers in adequate and feasible way. Then you need to determine what type of home theater system you require or have at present because there are a wide range of types of home theater system available out there in the market. Generally the choice will be dependent on the basis of channels and watts they have. The substantial watt power will be required if you are willing to have a surround sound speaker system for HDTV viewing. Hooking up a surround sound system to your digital TV also includes placing the audio and video receiver appropriately. The best place to keep the A/V receiver is right in front of the TV set. If you are going to use any other device with the system, such as a video game console or a blue-ray DVD player; it is suggested to place it right next to the receiver. The most important is to set up the speakers according to their channels. If you have a 5.1 speaker system, you need to place the sub-woofer at a corner from where the sound effect will not be absorbed and it will be felt in the most impressive way.

The front speakers are required to be placed roughly four to five feet from the television; the rear speakers should be set in the same pattern, but in the rear at appropriate distances. After everything has been implemented you are to check the real surround system effect by having stood in the middle of the room. Remember one very important thing: the more the number of speakers, more adjustments you will need to make for getting the desired surround sound.
