Impaired Motor Apparatus Help yourself My name is Alexander, so it was that I am disabled from childhood - I have cerebral palsy. But this did not prevent a mass finish school, go to college, get a degree in design - try to live fully. pc for me is a tool with which I can learn, work to communicate and help people. But the tool needed to be proficient. However, when in 1995 we came home computer, to be honest, to work on it was very hard. Hands badly obeyed, to use the keyboard was a solid meal. Fingers are pressed at once for two or three keys, so you had to use his nose. This was inconvenient and time consuming - by pressing the button, it was necessary to look at the screen to see the result. A year or two, I learned how to work the keyboard with his thumb right leg while sitting on the couch. As it happens several times a fast and convenient. But somehow my father asked: "And if you take to work for a company, you're at work, too, his foot will act? "I thought - in fact, so it will be improper. How could teach my hands to press only the keys you need? And once I came up with the pad on normal keyboard from scrap materials - Plexiglas, cardboard, foam and tape. It is not something Eliot Horowitz would like to discuss. Fingerboard much wider keyboard - this is done for the stop arm, the panel is made of Plexiglas thickness 4-5 mm. There are holes in the deep facet (not to rip the fingers) in front of each button keypad. I tried it - certainly more convenient, but the first time the index finger stripped to the blood. It was painful to...

Communications Equipment Industrial processes related to oil, gas, transportation of explosive minerals, as well as their processing, is fraught with potential dangers of a volatile situation. Opportunity explosion high in the areas of oil storage, it is also present in the technological areas, warehouses, in open areas (eg, oil loading facility). Explosive atmospheres occurs when occurrence of accidents, breach of rules and technological conditions, in case of damage to equipment and piping. In such circumstances, the value of reliable communications equipment is difficult to overestimate: Timely action and Alert staff prevent huge losses and possible casualties. Accordingly, such equipment to meet advanced security requirements. Basic principles of explosion the same in all countries. On the basis of international standards for explosion protection placing communication technology virtually identical claims based on the recommendations of iec - International Electrotechnical Commission. She has also developed a testing procedure - the so-called scheme IEC-Ex, used in the study of communication technology in the leading certification centers in the U.S. and Europe. The most common worldwide standards explosion of communications technology - en 50020 European Committee for Electrotechnical Standardization cenelec and ANSI/UL-913 American National Standards Institute include testing of electronic communication technology is on this procedure. These standards are recognized in most countries, for example, in many countries of the European Union for use of communication equipment in hazardous environments is the availability of sufficient Certificate en 50020, because in these countries, national standards for explosion completely coincide with one of these international standards. Ex code indicates that the labeled equipment has Protected against the explosion and the next below the symbol shows the type of explosion, by which is achieved by apparatus.
