Who invented wifi? Is there a patent? Wireless network is a wireless network technology defined by IEEE. When IEEE formally defined the standard of 802. 1 1 in 1999, IEEE selected and recognized the wireless network technology invented by CSIRO as the best wireless network technology in the world, so the wireless network technology standard of CSIRO became the core technology standard of Wi-Fi in 20 10. The wireless network technology was invented by CSIRO, an Australian research institute, in the 1990s, and successfully applied for the wireless network technology patent in the United States on 1996. (U.S. Patent No.5,487,069)
The inventor is a research team led by Dr. john O'Sullivan, an engineering graduate from the University of Sydney.

No.5,487,069), the inventor is a research group composed of engineering graduates of the University of Sydney led by Dr. john O'Sullivan, a graduate of the University of Sydney.
IEEE once asked Australia to give up the Wi-Fi patent and let the world use Wi-Fi technology for free, but it was rejected.
Australia * * * subsequently won the lawsuit or settled out of court in the United States, suing almost all electrical and telecommunications companies in the world (including Apple, Intel, Lenovo, Dell, AT & amp； T, Sony, Toshiba, Microsoft, Acer, ASUS, etc. ).
Wi-Fi is praised by the Australian media as the most important scientific and technological invention in Australian history, and its inventor John.
O 'Sullivan was called "the father of Wi-Fi" by the Australian media, and won the highest national science award in Australia and many praises around the world, including European institutions and European patents.

Who invented the patent of water source mobile drip irrigation? It was invented by Liu, Shang and Liu of Longjiang County, Heilongjiang Province. In 2006, their mobile drip irrigation system won the national utility model patent (patent number: ZL200520 1 19225.5). Its innovation lies in the way of moving water source, moving water head and moving drip irrigation pipe, which effectively solves the drought resistance problem of crops in semi-arid areas, especially in plots without water source, which can ensure stable and high yield of crops. It is an effective and practical drought-resistant equipment at present.
I. Type composition and operation mode:
The small mobile drip irrigation system is mainly matched with tractors, trailers and water tanks owned by farmers, and consists of booster pumps, water pipes, quick connecting devices, filters, pressure gauges, control valves, drip irrigation pipe, capillaries and header laying devices. Its operation mode is to lay 6-8 plants at a time, one plant 1 25-170m, and drip irrigation once1mu.
Second, the main features:
1, wide application range: it is suitable for drought resistance of all kinds of plots and crops in the whole growth period, and is not affected by the presence or absence of water in the field, plot slope, crop height and wind speed.
2, remarkable water saving and good drought resistance effect: farmers use 2.5 tons of water tanks, two vehicles can drip irrigation 1 mu, and only 5-6 tons of water is used per mu. The drip irrigation pipe with close dropping distance and small flow rate can form a continuous and uniform moist zone with a width of 30 cm on the ridge, which is equivalent to the rainfall of 20 mm, and can completely meet the needs of crop physiological water use.
3. One-time investment benefits for many years: drip irrigation pipe is compensated by the best domestic pressureless compensation, and its service life can reach 7-8 years.
4. Easy to install and use, flexible and mobile: make full use of farmers' existing equipment. 10 can be installed in a few minutes, and farmers can drip irrigation anytime and anywhere.
5. Low execution cost and high operation efficiency: According to the actual measurement, the cost per mu including water transportation and operation is only 12- 13 yuan. According to the calculation of 2.5 tons water tank, it takes 20 minutes for a truck to drip irrigation and 40 minutes for an acre of land. When the field moves, there is no need to roll up the drip irrigation pipe, which can greatly reduce the labor intensity and improve the working efficiency. If two waterwheels are used for continuous water supply, the operation efficiency will be higher, and the operation can be carried out in one day 15- 18.

Priority:
The utility model discloses an eye chart with a box which can correct myopia and amblyopia, belonging to an eye chart used in ophthalmology. The middle of the front of the box with box eye diagram is open, and upper, middle and lower lighting lamps are installed on the inner sides of both sides. There is a socket in the center of the top of the box for changing different eye charts. There is also a set of hyperopia glasses according to the law of correcting vision and matching the eye chart. A cassette visual acuity chart which can correct myopia and amblyopia can be used for general vision test and back protection. Its lighting is divided into upper, middle and lower sections, which can concentrate the detection range, help children who can't confirm the location of detection symbols and children with low IQ to detect normally, and save electricity. It is important that the eye chart and a set of hyperopia glasses are operated according to certain rules, which can improve myopia and amblyopia in a short time and reach or approach normal vision.
