Introduction
Since the industrial revolution, the technology had progressed to extensive steps.The technology had changed the human life because it makes our work easier also it allow a better development in the sciences.
On this work we show three technological objects that change the way of life of the peoples: the car, the television and the cell phones. These inventions had allowed us to travel to remotes places (the car), to inform and to entertain the people (T.V), and tocommunicate with out or our range (cell phones).








Television

The Television is an electronic gadget that picks up and reproduces the T.V signals. Usually have a screen and one remote control.

In January 26, 1926 was the first time that the little screen shows moving images. This day, in a scientific laboratory of London Jhon Logie Baird, a Scottish engineer made the firstcommercial television. This T.V was a mechanical object that were based on a rotating disk that contained various holes in spiral order, it allowed to realize a exploration “line for line” to a strongly brightly image. The first mechanicals systems were of 30 lines to 12 figures but it was improving with the spend time.

Working
Firstly, the camera receives light of the stage, this is puttingin its system and a group of lenses conduct it to various photodiodes in a CCD chip. There the light of the scene is converting in a video signals. At same time, one microphone captures the sound and also is converting in an electric audio signal. Both compound signals are sending to a satellite and this both sending to a receiver that take the signal through of an antenna, a satellite or a for acable. The T.V receives the signals. There, it conduce the audio signal to a amplifier and to high-voice.
The color TV was launched in the U.S. and other countries in the 1950s. In Mexico, the first color broadcasts were made in 1967 and in the following decade in Spain. Over 90% of households in developed countries now have color television.

With time, the televisions had improved. The firsttelevisions was in “black and white”, with a very basic system, but now the televisions have unlimited functions. The most news televisions are very smart; these can to recognize our movement and also we can to navigate for internet, to see 3D films, to play video games and do a lot of thing without leaving our armchairs.

















The Telephone

Inventor: Alexander Graham Bell was the official creator with Elisha Gray, but this isn’t the truth because Graham Bell only paid to have the patent. The real inventor was Antonio Meucci, he only was able to show some planes and demonstrate the purpose of this great machine: That is the reason of the fake inventor.
Date of creation: in 1871 Meucci demonstrated the functionality of the Phone, in 11/June/2002 before a lot of years of investigation and searches; in an official congress of USA the authorship of the phone was given officially to Meucci.
Utility: Now a day the phone is one of the most important methods of telecommunication, we can see it in a lot of places like homes, offices and parks. The phone still allow to us to talk with another people but now we use some codes, like theCountry codes, States codes and more.
Since the creation of the phone the inventors take the original phone and add some special features to improve the functionality of this and make this more accessible and cheap. Some of those characteristics are:
* Add better microphones
* Improve the Guided Transmission System (GTS)
* Create a wireless GTS, this change make the communication...
