Polarized sunglasses are manufactured according to the principle of polarization of light. We know that when the sun shines on the road or water surface, it directly irritates the eyes, making them feel dizzy, tired, and unable to see forever. Especially when you are driving a car or performing outdoor entertainment activities, it not only affects our work and entertainment emotions, but also affects our judgment of objects and causes danger; long-term direct sunlight exposure can also cause a rapid decline in vision, Formation of myopia, hyperopia, astigmatism, or cataracts. The special effect of the polarizer is to effectively exclude and filter the scattered light in the beam. The light can be put into the eye's visual image on the light transmission axis of the positive track, so that the visual field is clear and natural. Just like a jalousie, the light is adjusted into the same direction and enters the room, naturally making the scene look soft without glare. Dazzling polari

Temperature is one of the physical variables that people generally care about in real life. It is inseparable from our daily life, production and scientific research activities. The perception and measurement of temperature changes have always been essential in human life and production. The temperature-measuring NTC thermistor has already replaced the higher cost because of its more sensitive negative temperature characteristics, higher material constant (B value), faster response speed, reliable performance and low cost. Pt100 is widely used in all applications where temperature measurement is required. When the ambient temperature is greater than T1, the error is amplified, and the drive system is turned off. When the ambient temperature is less than T2, the error is amplified. A3 starts the heating unit in reverse to heat the system.

The pneumonia epidemic caused by the new coronavirus overshadows the Spring Festival of the Gengzi year. In the process of preventing and controlling the new coronavirus epidemic, medical products such as ventilators, monitors, oxygen generators, negative pressure ambulances, and forehead guns have played a significant role. The non-contact temperature measurement method of the forehead gun can avoid contact cross infection and play a convenient and quick role in preventing and controlling the epidemic of the general public. Forehead guns and ear thermometers use thermopile probe infrared thermometers to measure the radiant energy emitted by an object. According to Boltzmann's law (E = σεTⁿ), the greater the radiant energy, the higher the object temperature. After transforming the infrared radiation signal into an electrical signal, it can be finally converted into the temperature value of the measured target after being corrected by an amplifier and a signal processing circuit and

In the process of carton packaging printing, the printing process is particularly particular. Different printing processes will produce different printed products. Here are some printing processes in color gift packaging box printing. Gravure:   Compared with other printing methods, the ink color of gravure products has a more full three-dimensional impression, rich levels, and clear lines. This printing process is suitable for printing large quantities of color gift packaging box products. Standard and other products. However, due to a series of factors such as complicated platemaking technology, long cycle time, high platemaking cost, and environmental disadvantage, gravure printing is less used;   Offset printing:   Offset printing is offset printing, which is a type of offset printing and the printing format can be flexibly changed. Not only for the printing of color gift packaging box products, but also for the printing of paper products such as newspapers, posters, magazines; Si

At present, the sample printing market is mixed. When choosing a printing and packaging company , businesses can start with the following three factors and consider the choice comprehensively: First, look at the equipment Good equipment is an essential element for sample printing. At present, the better printing and packaging company in China, such as Wen Jie, use the Heidelberg series imported from Germany. Its printing accuracy is relatively high and the quality is stable. However, due to limited funds, some small printing and packaging company often use small-scale printing equipment made by Nissan or even China. Not only the printing cycle is relatively long, but also the printing quality is difficult to be guaranteed. Second, look at technology Printing technology, especially color management in prepress technology, is the key point to ensure that printed products are completely consistent with design drafts. Good printing companies generally use modern ICC color management techno

The selection of camping sleeping bag materials also marks the grade and price of camping sleeping bags. There is also a process of changing the quality of camping sleeping bag materials. When people are not satisfied with a large and heavy camping sleeping bag, a lightweight and small camping sleeping bag has become an inevitable substitute, so it has good compression and expansion. High-quality, high-quality cotton has replaced cheap, low-quality cotton. In order to improve the performance of camping sleeping bags, some styles use high-tech breathable fabrics for the outer fabrics of camping sleeping bags. DRYLOFT fabrics from the American GORE company are the most representative superb materials. In pursuit of perfection in use, down camping sleeping bags with good compression properties are becoming more and more popular with campers. 80% gray duck down, 90% white goose down and other excellent camping sleeping bags are on the market.

While GPON currently dominates the next generation PON market, some tier-one cable operators and international operators have yet to decide on a technology route that could upend this trend and push scale toward EPON. For years, two industry bodies have directed each version of the passive optical network iteration to use the same wavelength, so that traditional networks can use the same passive equipment, such as spectrometers and filters. It is understood that while the international telecommunication union (ITU) developed GPON, the institute of electrical and electronics engineers (IEEE) developed the EPON standard. In terms of 10G PON, both the ITU and IEEE standard bodies use the same wavelength for xgs-pon and 10G PON. According to a report by market research firm ResearchAndMarkets in October 2019, the compound annual growth rate of the global total PON market will reach nearly 21% from 2019 to 2025, and the sales volume will increase by about 28 billion us dollars. GPON alone c

You thought that keg of all Baltic Porter will be a big hit, but it's a month later and you still have a half-full keg sitting on your kegerator and you also can't stomach another pint. Is that beer good? How long before you want to wave the flag, and just surrender this beer? , it is probably a good time to discuss how long a keg stays clean. How Long Would Draft Beer Remain Fresh? There's not any one hard and fast rule for how long that a keg of draft beer will remain fresh. This is especially true for art beers because distinct styles of beer last longer than others. A fantastic rule of thumb is the shelf life to get a keg of pasteurized beer is all about 90-120 days (or 3-4 weeks ), and unpasteurized draft beer will last about 45-60 days (or 6-8 weeks) when stored in the appropriate temperature. Many domestic and import beers are pasteurized. If you're unsure whether your beer has been pasteurized, then treat it as if it's unpasteurized. An important issue to r

Although there are some difficulties in this winter in 2018, it is gratifying that the upgrade and transformation of the entire LED display industry has not slowed down. On the contrary, with the increasingly fierce market competition, manufacturers have begun to leap from product, technology and service volume to qualitative change. In 2019, LED display manufacturers want to develop opportunities in a cold market environment, they must completely change the concept of "single hammer trading" to do business, and embark on the path of ecological synergy.   Of course, building an ecosystem does not require all manufacturers to transform from "selling products" to solution providers, but to establish a win-win platform based on market demand and suppliers, distributors, peers, and users. The core is to Solve two problems: how to build a good product, good service; how to establish a user-centered way to create a win-win situation. So how do manufacturers realize the

If you are looking for a new LED display , chances are that you are being overwhelmed with technical jargon and marketing superlatives claiming the finest pixel pitches and the highest resolutions. But what is a pixel pitch and how is choosing the right pixel pitch important for the success of your display? What is a pixel pitch? First, let's go back to basics. How is an LED wall actually built? An LED wall is put together out of LED tiles, which in their turn consist of multiple LED modules. These LED modules contain LED clusters or LED packages, i.e. red, blue and green light emitting diodes (LEDs) grouped in pixels. Pixel pitch is a technical specification that is used to differentiate between LED tiles. Note that the pixel pitch specification can also be used for other display technologies like LCD, but in this post we're only talking LED. The pixel pitch is the center-to-center distance between two pixels, usually measured in millimeters. If you have a 10mm pixel pitch, i
