As one of the most convenient and accurate biometrics technologies, iris recognition technology can acquire the clear iris image of individuals and is directly affected by the environment. This environmental constraint has also become a technical challenge for all parties involved in the iris recognition industry to break through. Even the most recent Fujifilish iris phones are also being suggested to be unlocked by using an alternative password or graphical unlocking feature in outdoor glare. Iris glare is difficult to identify two reasons: First, the rapid contraction of the pupil in glare, the iris segmentation becomes extremely difficult; Second, the sunlight near the infrared part of the light can easily saturate the image sensor, so that the iris image Signal-to-noise ratio is uncontrollable resulting in recognition failure. Recently, Wuhan Hong Technology Co., Ltd. (hereinafter referred to Hong Technology) to obtain a breakthrough in solving this problem stage, Rainbow Technology team developed a special light algorithm and design a unique hood designed to achieve up to 100K LUX Strong iris recognition. The iris recognition terminal device based on this technology can realize fast and accurate identification in the direct sunlight all-weather environment. According to the actual needs of customers, Rainbow Technology has further optimized its self-developed iris recognition algorithm. Algorithm-based optimization can effectively improve the recognition ease-of-use in bright light environment. At the same time, in order to create a relatively isolated outdoor identification environment and to adapt to higher direct sunlight intensity, Rainbow Technology is another way to add the patented shade to the existing terminal access control equipment to enhance the durability. Up to now, all kinds of terminal equipment under the company's product line have been fully registered in the normal light environment and glare recognition. Combined with the existing infrared fill light amblyopia environment recognition capabilities, Hong Technology various end products have been truly all-weather operations, greatly expanding the product range. The second detention center in Wuhan City is the first user of Hong Technology Iris glare identification products. Currently, the detention center has established a huge database of criminals iris. On Sept. 21, at the detention center's request, Rainbow Technology installed an iris access control terminal device using the latest technology for the discharge of prisoners and the management of collective labor. After repeated use of testing, detention center staff said that the product experience is very good, light, dark and other environments can be achieved quickly and accurately identify. Rainbow Technology's latest innovations can further expand the iris recognition product application scenarios and improve the user experience, is expected to lead the industry to develop new trends. testing on the spot Sodium Tripolyphosphate, Na5P3O10, Molecular weight 367.86, white powder; Melting point 622 °C. free soluble in water, aqueous solution appears ACID. It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity. It is an inorganic compound with formula Na5P3O10, is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

It has different bulk density, i.e. low density 0.35-0.6g/cm 3 , medium density 0.6-0.8g/cm3 and high density 0.8-1.0g/cm3. This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.
It can be used as one of the main auxiliaries for synthetic Detergent, synergist for soap; water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.
As an oil contamination resistance agent in paper production; As in foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
