According to the PCWorld website, unlike other smart glasses with small LCD screens, Fujitsu developed smart glasses that use lasers to directly project images onto the user's retina. At a technology show this week, Fujitsu demonstrated a prototype of smart glasses that can be connected to mobile devices or cameras mounted on glasses. For example, when connected to a smartphone, web pages or other network information is projected onto the user's retina through the smart glasses; when connected to the camera, the user can directly see the scene in front. Smart glasses are very useful for visually impaired users when connected to a camera. Although Fujitsu is designing this smart eyeglass as a vision aid, its technology will open up new solutions for smart glasses. According to PCWorld, a laser projector is embedded in the left eyeglasses of the smart glasses, which can emit harmless RGB laser light onto two small lenses mounted at an angle, and the light is transmitted to the retina. In the demonstration at the technology exhibition, the wearing experience of Fujitsu smart glasses is similar to that of Google glasses, and the left eye of the user can see the projected flower image. However, if the relative position of the projector and the lens is incorrect, it is difficult for the user to see the image. In addition, the design of Fujitsu smart glasses is quite cumbersome, but Fujitsu plans to "excellent" its design. The idea of ​​using a laser to project an image onto the retina has been around for decades, but until recently, the miniaturization of optics has become quite difficult to use in glasses. Fujitsu and its partners can produce small lenses that allow light to enter the human eye. Mitsuru Sugawara, CEO of QD Laser, a laser technology development company that was spun off from Fujitsu, said, "With this smart glasses, users with low vision can read, read newspapers, watch bulletin boards, watch timetables and walk around outdoors." Fujitsu got QD Laser help in the development of smart glasses. PCWorld pointed out that Sugawara said that Fujitsu smart glasses are connected to the phone box size control box, and the size of the control box will be reduced to the size of the smartphone in the next few months, and wireless connection will be realized in about three years. QD Laser plans to commercialize this smart glasses in March 2016, priced at about 2,000 US dollars (about 12,225 yuan). Originally for low vision users, this smart glasses will be available in Japan, Europe and the US.
Pentaerythritol is mainly used in the coatings industry, can be used to manufacture alkyd resin coating, can make the coating film hardness, luster and durability.It also USES up with anger paint, lacquer and printing ink of pine resin needed raw materials, coating and drying oil, smoldering sex and aviation lubricating oil and so on.
