NPR: Latest Technology for the Safety on Roads

For better safety, the different countries around the world are now using NPR technology. NPR stands for number plate recognition. NPR technology has become very much famous as it is a very good source of security system. The law and other rules and regulations of the country can also be checked and protected with the help of this latest technology. Basically, NPR technology is used by the police bureau of the country. With the help of this technology, the police can trace number of different cars for the purpose of various taxes such as toll tax, road tax, pay per use tax, parking fee, and so on. The main countries using this technology are UK, USA, Italy, Germany and other European countries.

NPR technology was introduced in 1970’s in UK and became famous around the world. The technology is still on research and is evolving. This technology works with the help of IR strobe light, also known as infrared strobe Trizetto login . NPR technology carries out its functions through the close circuit cameras that are equipped with IR strobe light. This helps in recognizing the number plate of any automobile during dark night. The traffic on the roads can be easily managed through this technology. These lights are used for illumination purposes. IR strobe light is also used by the detectives for the negligible effect on that particular investigation which is carried out at night.

NPR technology helps in reading the picture of the car or any other automobile that is why the name of this technology is provided as Number Plate Recognition. The picture of the automobile is read with the help of optical character reader, i.e. OCR technology. When any person breaks the rules of traffic at night, police can easily catch him and penalize him by reading the picture of his car. Stolen cars can also be recovered by the assistance of this technology. IR strobe light scans the car and the picture of the car is taken out and compared with the details of the stolen car such as model of the car, address of the owner, social security details, etc. By this process, stolen cars can be easily traced within a few seconds. This technology is more active and faster than the hand-operated process.

Utility grade wind turbines have become so technologically advanced that they have improved the cost of energy of wind enough to become more mainstream than ever before and compete with todays conventional energy sources. We have decided to conduct an investigation of the patent landscape to see what technological trends have emerged thus far and what we might be able to infer for the future direction of wind turbine technology. At this time, the assessment was limited to the most prevalent sector of wind turbine technology utility grade, horizontal axis wind turbines.

The search was conducted utilizing a comprehensive approach, as well as thorough reading and examination of results. A patent database and search portal was used which covers 90 different patent authorities worldwide, including 20 countries which provide full-text file search as well as legal status information. We first identified a set of keywords which would provide an all-inclusive set of search results. We also identified patent classes to search in order to ensure that relevant results would not be omitted. Lastly, a set of assignees of over 100+ companies who have currently or previously produced wind turbine technology / components was searched.

Aggregation of these results and elimination of duplicates as well as false positive results has led to a total set of 1461 US patents dealing with utility grade, horizontal axis wind turbines. While the scope of these search results was limited to US issued patents, most of these have equivalent foreign filings.

The results have been grouped by Assignee, and it should come as no shock to industry watchers who the top 3 assignees are for utility grade, horizontal axis wind turbine patents. For the sake of compactness, only those with 4 or more patents were included in the chart.

The search results were read and analyzed to determine a keyword classification that indicates the specific technology and component to which the invention refers. The component literally refers to the wind turbine component which the invention deals with, i.e. blade, tower, generator, gearbox, etc. The technology refers to the nature of the improvement, and deals with such topics as performance improvement, reliability enhancement, manufacturing tools or processes, safety or grid compliance. The search results are presented in a format in which each individually issued patent was assessed and classified. Therefore, continuations and divisionals are included as separate line items in the results. The following is indicative of the keyword classification methodology.
