June 12, 1967, the Soviet space station was launched to study the planet Venus. With its help, mankind for the first time managed to measure the density, temperature, pressure and chemical composition of the atmosphere of the planet. In addition, the spacecraft was able to make color images of the surface of Venus that played a tremendous importance for world science.
Interplanetary station “Venera-4” was developed at an Engineering plant named after S. A. Lavochkin. She managed to reach the planet’s surface after 1.5 months after launch from Earth and to make a successful descent by enormous overloads of up to 300 terrestrial accelerations (the human body, for example, to be able to withstand acceleration up to 10 g, and even then only in a specially designed spacesuit).
Spacecraft “Venera-4”
On researching the lander took only half an hour — during this time he spent a lot of measurements and had to pass their results to a distance of over 75 million kilometres.
The measurement made by the station “Venera-4”, confirmed the assumptions of astronomers about the unsuitability of a planet for life: the temperature at the surface of Venus is hot and is approaching 300 degrees Celsius (and it is only at night!), all the water is concentrated in clouds, and precipitation on the planet do not fall out never. Breathing is also nothing — 90% of the planet’s atmosphere consists of carbon dioxide, nitrogen and oxygen occupy a paltry 7% and 0.4—0.8 percent.
June 12, 2009 analog TV has completely stopped its work in the United States. All analog transmitters TV signal was suddenly disconnected, and from this point the United States completely switched to digital TV.
The transition to the new standard of television has cost the US government $2 billion and was accompanied by a rush of demand for new TVs and TV set-top box to receive digital signal. Budget funds were used for improvements of infrastructure, and for viewers was provided only vouchers in the amount of $40 for purchase of digital receivers.
Millions of analog TVs in the USA were sent for recycling after the transition to digital broadcasting
The Congress was opened by the transition to digital broadcasting in October 2005, and completely “bury” analog television is planned in winter 2009. TV manufacturers were obliged to supply models with digital receiver ATSC standard, broadcasters and Telecom operators to war over frequencies that were freed on the eve of the closure of analogue television, and all States began large-scale construction of networks that are comparable in coverage with those that were under the old broadcast type.
Initially, the transition was scheduled to spend the $1.34, but in January 2009 it became clear that this amount is not enough, and make digital TV still can’t 6.5 million Americans. Of the budget allocated additional subsidies, and the date of shutdown of “old” television, therefore, postponed until the summer.
Note that in Russia the exact date of the abandonment of analog TV is not made public until now. To see the progress in this direction on the website of FSUE “Russian television and broadcasting network”.
12 Jun 2011 Lenovo began serial production phone with a transparent display. On completion of the device after the initial announcement took the company a year before that, from afar, the prototype boasted a model at a fashion show, but then “teasing” is not reached.
However, the result justified all expectations — 2.4 inch OLED display manufactured by TDK is not just a display standard for mobile phones 320×240, but was transparent at 40% (you must have at least there’s something to be viewed).
Lenovo S800
The rest — an ordinary phone without any claim to future technologies: WAP, EDGE, 2 megapixel camera, MP3 player, Java games. And “spearhead” Chinese phone call can’t Sony hurry up before. But Lenovo scored a fashionable phone at an important period of development, and buyers got one of the original “up” before on the stage in full growth turned smartphones.
