Polymethyl methacrylate (polymethyl methacrylate, also known as acrylic or plexiglass), is also known as Agali glue in Hong Kong. It has the advantages of high transparency, low price, and easy processing. It is a commonly used glass substitute material . The polymethyl methacrylate monomer is methyl methacrylate (MMA, acrylic monomer). Excellent transparency and excellent aging resistance; its ratio is less than half of ordinary glass, but its resistance to fragmentation is several times higher. It has good insulation and mechanical strength, and has strong resistance to acids, alkalis, and salts. It is corrosive and easy to process. It can be glued, sawed, plane, drilled, engraved, polished, screen printed, sandblasted and other manual mechanical processing. After heating, the pressure mold can be bent into various acrylic products.
Fresnel Lens is equivalent to infrared and visible light convex lens in many cases, the effect is better, but the cost is much lower than ordinary convex lens. It is mostly used in occasions where accuracy is not very high, such as slide projectors, film magnifiers, infrared detectors, etc.

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
The Fresnel lens has two functions: one is focusing, that is, the pyro-infrared signal is refracted (reflected) on the PIR, and the second is to divide the detection area into several bright and dark areas, so that it can enter the detection area A moving object can produce a changing pyro-infrared signal on the PIR in the form of a temperature change.
Sets Up Hisense U9 TV for 2018 TV Market
On March 10th, at the China Household Electrical Appliances and Consumer Electronics Expo (AWE2018) in 2018, the AWE Aipulan Award Ceremony was held. After several rounds of rigorous screening, Hisense 75-inch U9 series ULED super-quality TV won the "2018 Epland Award and Intelligent Innovation Award" for its perfect experience in display technology innovation and artificial intelligence technology upgrade.
The Epland Award, organized by AWE Organizing Committee, is hailed as “the Oscar in the world of smart livingâ€. The award-winning products not only represent the highest technology level and the most fashionable design in the home appliance and consumer electronics fields in the year, but also are the vanes that lead the consumer trend. Hisense U9 series television stands out in more than 30,000 AWE exhibits and becomes a boutique boutique. Its outstanding picture quality and artificial intelligence experience have met people's expectations for a better life and smart new experiences. They are unique in the high-end market.
Hisense U9 is the "2018 World Cup Limited Edition TV," which was launched at the CES in the United States earlier this year. It uses Hisense's independently researched and developed 1000Zone ultra-definition TV technology and 4096-level fine dimming technology to present levels, details, and depth of field that ordinary TVs cannot express. As a result, U9 has won the "Global Annual Display Technology Gold Award" that represents the highest award in the CES display field.
In addition to the application of the 1000Zone ultra-definition television technology, Hisense U9 also employs quantum dot four-dimensional restoration technology and incorporates the Motion Flow intelligent motion frame measurement system. In this way, U9 TV's color reproduction is more realistic and visually more comfortable, allowing fans to truly enjoy the visual experience of on-site viewing.
"Smart life, global platform" is the theme of this year's AWE. Hisense U9 TV fully demonstrates the industry-leading artificial intelligence experience. It is equipped with an independently developed VIDAA AI artificial intelligence system, and is supported by the state-level Digital Multimedia Key Lab and the “Learning†operating platform. Voice interaction and image search capabilities give users a very novel experience.
Hisense AI system can not only achieve six consecutive human-machine dialogues, can identify 33 kinds of personal relationships, but also supports six major dialects. It can use hundreds of living scenes such as takeaways, airline tickets, hotel reservations, shopping, and Chinese and English translations. During the World Cup, the “figure search†function will exert tremendous power. When users watch the World Cup, they can use the “one-button screenshot†to identify the information related to the searched players, the same items, and the ability to buy and sell the same items on the television. The scene of the goal scoring can also be shared in the circle of friends through screenshots.
