On December 10 of & 39; years 1868, the first light-signalling devices has been put into service. The bulky, primitive device busy, filled with color lights to use & 39; gas after nightfall, the arms and semaphores. He demanded an operator, it is always, it was in the course of & 39; use. Twenty three days after the first traffic signal light was employed, it has exploded - violations of police officers, which was assigned to the lights and signals. This unfortunate event, in the question of the practical implementation of signal lights lights.
Despite market volatility, and ultimately catastrophic results, the first set of traffic lights with light, inventors and engineers followed strammem & l 39; idea. Given that more and more traffic on the roads and collected roads, & 39; use of signs and stop & 39; officers were crosses on fields of practice less - and Increasingly dangerous.
Sometime about 1912 the first electrical signal has been placed on the market. These first units had only red and green lights, but. In 1917, in Salt Lake City, Utah, a series of traffic lights were interrelated, this link & quot; sequential & quot; six junctions. This system was developed with a manual single switch.
In 1922 Garrett A. Morgan applied for a patent on a signal light, in view of its own design. The patent was issued for & 39; next year. This began the myth that Morgan was the inventor of & 39; traffic & 39; to light.
Between time of the first traffic lights were put in place, and the beginning of 1960 & 39 ; many improvements have been made, and numerous experiments. The biggest problem for the traffic lights at that time was simply that & 39; it depends on the timer only. East-West transport would be a green light for 3 minutes, then trigger a timer, the green light for the north-south traffic - and so forth. The length of time could be adapted, but often have problems with the parameters of the River traffic.
In the beginning of 1960, traffic has begun to implement engineers & quot; & 39; induction loops d & quot; management of the flow of traffic & 39; for passing. The loops, which can detect vehicles in certain lanes at intersections, the lights controlled & 39; timers. The induction loops d & 39;, the lights of traffic on the hand, on the time of day. Do not ever rely on traffic lights red 2-3-4 or 5 minutes - even if it is not cross & 39; transport. Traffic engineers sun in an outpouring of praise from drivers.
In of 1970, technological advances in metallurgy, plastics, rubber and launched a change in the way the vehicles were manufactured - and how they were manufactured. No more, all that is in the scoreboard on the wings in high-tensile steel iron content. & 39; C was in the context of these developments, the myths of the outbreak of traffic lights has begun. Since then, it has become worse every year, more than alloys, plastics, rubber and in the construction of vehicles.
It seemed logical that the amount of the estate at a crossroads, which would trigger the green light. & 39; C is a myth. It seems logical that the mass to trigger a crossroads, the green light. & 39; C is also a myth. Given that the human & 39; n have been unable to traffic through the & 39; adding weight, or do more to the weight of their vehicles, the company began to seek d & 39; other responses. The latest addition is a myth, that there is a & 39; invisible curtain that, if broken by a vehicle, triggers a green light. It is assumed that the curtains that for a portion of the roadway, and if you are not & 39; against the curtain, which you & 39; n have not received the green light. & 39; C is also a myth.
Actually, inductive loop technology is very simple. An inductive loop & 39; is nothing other than a huge & 39; and very low electromagnets. The notion & quot; loopset & quot; refers to electro-magnets used in the iron industry & 39; to recognize. They are generally in many industrial applications. They are cheap to install loops maintain.
Inductive and at the traffic light by the large coils of & 39; landfill F deldraht slightly below the road surface. The cables are equipped with tar and rubber black. A small current passes through the wire, what & 39; reaching an electromagnet. The loop is equipped & 39; one meter, measures changes in the loop. Magnets iron to react - no rubber or plastics or aluminum. So if enough iron & 39; present at the inside of the loop, the cycles of traffic lights green.
The vehicles, the most important problems with the outbreak of lights are motorcycles and mopeds, followed by small cars and Truck, and then 4x4s and SUVs. Drivers of these vehicles are often undetectable rest, the burning waste fuel, increasingly enjoyed their overheated engines, and irritate your growing.
To positive is green, you can use a bowling ball-sized piece of iron around the earth - but this will not be to function only if in your tribe. & 39; C is too far from the field sensing weakness of the loop. In the trunk, you need two or three balls of iron. OR you can use a traffic light signals Sorcerer changer http://signalsorcerer.com/.
Signal Sorcerer traffic light changer use of their own technology to identify & 39; induction loops of your vehicle - whatever their size, weight and mass. Simply install the signal Sorcerer of your vehicle and d & 39; induction loops that control traffic lights recognizes your vehicle, and you give the green light!
Signal Sorcerer requires no power, you have a long life, is legal everywhere, installed in less than five minutes without tools and is fully insured. Sorcerer signal traffic lights were changer in the world for & 39; year, and units are available for all applications, including police motorcycle divisions of vehicle safety, fleet vehicle, personnel and means of transport.
