Liu Yanqun shows patent certificate
â– Developed the "Transportation Electronic Signal Language Commander" 10 years ago
■The “speaking signal light†installed on Shenyang Street Road is from a company in the south.
■“Does this situation constitute an infringement?â€
Looking at the "speaking lights" on the streets of Shenyang, Liu Yanqun, an engineer in Shenyang, was somewhat lost. The patents developed as early as 10 years ago have not been applied in Shenyang; the signal-speaking equipment used now has nothing to do with him.
A complex developed "talking lights"
"I am proud of the 154-year-old Liu Yanqun who let the signal light speak. He is an engineer at Shenyang Xinghua Electric Manufacturing Co., Ltd. On the afternoon of the 5th, Liu Gong took the national patent certificate and told reporters a source. The signal light complex. In 1996, the traffic police mostly stood in the "post building" to direct traffic, and only one year later changed to the traffic island located in the middle of the road, the traffic police command sometimes had to "scream out loud."
All of this was seen by Liu Gong. "At that time, I went to work every day to look at the traffic police and the command. I was also very shouting. I felt very hard. 1 Liu Gong felt that he should do something to ease the burden of the traffic police. At the beginning of 1997, a situation that was accidentally seen deepened the work of Liu Gong. Kind of thought. "The road crossed the road that day, watching a blind man trapped in the middle of the road, when the green light turned red. Both sides are passing by, the blind people are trapped in the middle and turn around..." Liu Gong said, "I don't have a taste in seeing that scene." â€
Therefore, Liu Gong, who specializes in electrical technology, is preparing to develop a device that not only can reduce the burden of traffic police, improve work efficiency, but also provide the most direct reminder service for the blind and the general public to let the signal light "talk"!
