To protect student safety, New York officials proposed to increase surveillance cameras around the school

On June 19, 2018, the chief of the Municipal Police Headquarters, James O'Neill (spokesperson), appealed to the state government to install more surveillance cameras proposal as soon as possible.

According to reports of the United States "World News", the New York City Mayor's Office, the Municipal Police Chief James O'Neill, and Chen Wenye, director of the Municipal Police Traffic Safety Bureau, and others, publicly appealed to the state on June 18 local time in Brooklyn. The government passed a proposal to add hundreds of speed surveillance cameras around New York City’s schools to further protect students’ safety.

James O'Neill, Chen Wenye, Brooklyn Governor Eric Adams, Councilman Justine Brannan, and 264 Elementary School Principal Patrice Edison lead hundreds of students’ parents in 89 Avenue, 4th Avenue, the 264 elementary school entrance, appealing to the surveillance ip camera issue.

O'Neill said that at present, speed monitoring cameras are urgently needed around New York City schools. These cameras can effectively protect children from accidental traffic accidents during their studies. However, the state must first adopt proposals to promote the establishment of these surveillance cameras.

It is reported that there are now 140 speed surveillance cameras in the city, which were installed in 2014. After the installation, drivers who are speeding nearby have fallen by 60%, and the incidence of fatal accidents around the neighborhood has dropped by 25%. This means that the surveillance camera has a warning effect on driver's specification driving.

The current state government is reviewing proposals that will allow New York City to add hundreds of surveillance cameras to 150 different school districts. Although the proposal received bipartisan support, it has not yet been finalized.

For the proposal, Shirley Chin, the parent of a Chinese student on the scene, said that installing a camera around the school can curb the driver’s fast driving behavior and make the student’s safety more secure. I believe most parents will fully support it. However, some people also believe that the camera is just an excuse for the government to obtain more fines. At present, New York City is penalized for violations of speeding at 50$, and it can get government revenue of 100 million dollars each year.

Which brand of Robot Vacuum is better? -part 2

The advancement of smart robots in Robot Vacuums allows people to use Robot Vacuums without spending too much effort or even spending time and energy at all.

If you want to do a good job of cleaning the floor in your home, you just have brains and memory that are not enough and you need to have excellent cleaning power. Traditional cleaning robots have appeared many obvious problems during cleaning. Because of the lack of power, many types of impurities cannot be cleaned. The TOMEFON TF-D60 Robot Vacuum has also made great efforts in cleaning.

The use of a roller brush enables the use of a floating roller brush for cleaning when there is a lot of dust and particles. It is worth mentioning that the brush bristles of the cleaning Robot Vacuum can also enter the gap during the cleaning process. This design makes it easier and more relaxing for people to get the floor cleaning done and without worrying about anything.

The TOMEFON TF-D60 Robot Vacuum also has a variable frequency suction nozzle, which can be switched freely and can target various impurities at home. People who have small pets in their homes may all spend time specializing in cleaning the fallen hair. When there is more hair on the ground, he will use relatively high power suction to clean the hair and keep the interior tidy.

When there is a satisfied cleaning robot at home, people usually do their own thing, so that they can make full use of their time. However, when a machine is in operation, it is inevitable that there will be noise, and the traditional Robot Vacuum will also have noise when it is working. The  TOMEFON TF-D60 Robot Vacuum can provide people with a more quiet environment after being innovative.

When people are resting and working, a Robot Vacuum has completed the sweeping of the entire home's ground. It does not require any specific operations by the people and does not affect people's sleep. It can be said to be quite ideal. What are you waiting for, why not choose a Robot Vacuum for yourself?

Which brand of Robot Vacuum is better? -part 1

Some people say that people can make a better and higher quality service for people's lives by making a small progress in science and technology. Robot Vacuums are no stranger to people nowadays. They have entered people's daily lives, allowing people to see real cases where technology changes real life. People do not have to worry about daily household floor cleaning anymore, can take a real rest at home.

In most people's opinion, the choice of home appliances still depends on the brand. TOMEFON can be said to be the veteran-level brand of the Robot Vacuum brand. Because it takes a long time to enter this field, the accumulated experience is more than those kinds of brands who just recently starting to study how to make Robot Vacuums, and the innovation is more prominent. It is also said that this well-known German environmental company, in 2018, once again took the lead in the sales list of global sweeping robots. As the top-three brands of sweeping robots for eight consecutive years, the brand has also become a hot target for the media. What kind of charm does it allow consumers to maintain with such high enthusiasm?

The HSIR+ multi-matrix intelligent composition system is a new attempt made by the TOMEFON TF-D60 Robot Vacuum in terms of internal intelligence. Break through the memory technology of traditional Robot Vacuums, it can be done when the cleaning work is not repeated.

Because traditional Robot Vacuums can only clean a certain area during cleaning, they cannot master the overall cleanliness. With the technical progress of Robot Vacuums, this situation has also been significantly improved. Because there is an intelligent system inside, it is possible to scan and build the entire environment before the work is carried out, so that new types of Robot Vacuums can be used and became a Robot Vacuum with brain and memory.

Xiaomi NINEBOT electric self balancing scooter unboxing

Nowadays, urban traffic is getting more and more congested, so electric self balancing scooter has become more and more popular. As the technology and performance of this kind of product have become more and more mature, more and more people have accepted it as one of the daily means of transportation. Today, we will review the latest best selling - Xiaomi NINEBOT electric self balancing scooter.

Driving situation

The city center is relatively crowded, the vehicle condition is also more complex, the NINEBOT electric self balancing scooter can basically use the small and flexible figure to easily go through between the vehicle, so much more flexible than the motorcycle. Sometimes, although the road surface is very rough, the shock absorption effect can also be achieved, and it does not feel particularly bumpy.

Speed

The highest speed of the NINEBOT electric self balancing scooter is 18km. This speed is relatively slow in the long straight road section, but it does not matter if the road conditions are complex. The designer group, I think, might consider the safety problems to prevent users from unsafe driving.

Lifetime

The official statement is that it can continue to travel 22km. I think this battery is reasonable enough to meet the needs. In addition, when the battery power is lower than 60%, I will charge it. The charging speed is really fast, which is very satisfactory.

Weight

The weight of the whole car is about 12.6kg. It is not tired to pick up in a short time. Adult men will feel easy to hold it.

Degree of control

As long as the attention is sufficient, there will be no basic security problems. I've tried (17km/h) and the braking distance is about 2.5m. I don’t think I need to talk about the driving skills. You will know how to control it once you have owned it without any pressure. If you have any question, you can ask in the comments.

Features of a good 3D headset

The 3D glasses work by displaying different images for each eye. The brain then interprets and merges the separated images into one, but with additional 3D headset features. This then allows the brain to think that the image is in 3D and thus creates the feeling of improved depth perception for the user. 3D-compatible TVs and projectors work by receiving a 3D signal that is then sent in different ways. This displays the left and right eye information as a single image that gives it a blurry appearance when displayed without 3D glasses. When using certain types of glasses, this image is separated to provide the 3D image.

Features of a good 3d headset

Durability

Active 3D glasses are robust and flexible. The lenses have been designed with flexible points, which extend the life of the lenses. In rigorous and independent laboratory tests, the 3D glasses have worked more than 2,000 times, offering unbeatable costs per show.

Automatic "ON / OFF".

To keep the glasses working at the time of the show, to reduce the operational interface of the theater and to better manage the battery life, the 3D glasses of the headphones automatically switch to "ON" and "OFF".

Aware of the environment

A good 3D headset can be used longer than ever, and their transmitters use environmentally friendly diodes. This is a key element of the 3D headset manufacturer who gives the ongoing commitment to "green technologies" and "earth-friendly" solutions.

Easy distribution and collection

In order to reduce the need for additional staff and monitoring, the 3D helmet has developed and made an available (optional) well-designed utility trolley (3D Trolley) for efficient distribution, collection, and storage of glasses.

No silver screen

Standard white screens can be used in both 2D and 3D, eliminating unwanted "hot spots" created by 2D presentations on silver screens. With its reflection of light focused towards the audience, a silver screen offers a narrower viewing angle as opposed to the lower gain matte screen which offers a much wider viewing angle.

The most brilliant 3D solution

3D requires as much light as possible. The 3D headset is equipped with the fastest shutter technology for the brightest image. The luminous efficiency of cinema using 144hz 3D glasses has been increased to more than 17%.

Guarantee

The 3D helmet components are tested for durability, ease of use, and accelerated stress. Most 3D systems include a 2-year warranty for all headend hardware, distribution module, IR transmitter, and IR tester. The glasses are included in this warranty.

Please note: Despite the robust design, the lenses are made of glass and are likely to crack when twisted. 

A new patent for Apple's unmanned vehicle - showing information on the windshield

According to media reports, the U.S. Patent Office recently announced Apple's patent on driverless cars. The patent shows that the system is able to collect the data monitored from the sensors and render it graphically on the windshield in a 3D AR technology. Judging from the sketch of the patent publication, the system can display the current roads, driving routes, distant 3D mountains, etc. In addition, in addition to real-time traffic, the system can also provide information on nearby attractions, interesting places, local customs, and more.

In the “Mission Impossible” movie, the HUD navigation on the BMW concept car once gave everyone a powerful expression. Although it is only a concept, it is not uncommon to apply HUD technology to vehicles. However, the vast majority are still used alone. The screen is not projected over the entire windshield. And the support for the AR does not seem ideal.

A new patent from Apple now shows that they are applying AR to vehicles through HUD-like methods. According to the U.S. Patent and Trademark Office's information, Apple has built an enhanced display content that can be used on windshields in new patent documents. With this technology, not only the navigation route can be displayed in the form of AR, but also the nearby attractions, local customs, and much other interesting information.

According to the description, this AR system will collect data monitored from sensors such as LIDAR and attach pre-produced 3D caption information to the current road environment to provide passengers and drivers with richer information content. In fact, not only the lines of navigation, distant mountains and invisible roads can be projected, which is equivalent to constructing a transparent three-dimensional map. For the rain and snow and other abnormal weather, it is a safer way to drive. Of course, since it is only a patent now, we can try to use a mini bluetooth projector which can connect with your smartphones to project the GPS content on the windshield.

In the future, especially in the continuous development of automatic driving, this technology has far-reaching significance.                                                                                  

Oracle plans to expand to build 12 more data centers

According to media reports, Oracle plans to build 12 new data center areas over the next two years to provide enterprise customers with cloud infrastructure services, and customers can rent online computing services and storage space. Oracle will set up two data centers in the United States and Canada and one each in India, Japan, the Netherlands, Singapore, South Korea and Switzerland. There is also a center to be set up in China, and Oracle will cooperate with Tencent Enterprises in accordance with the provisions on cooperation between foreign capitals and local companies.

According to media reports on February 13, the famous cloud service provider Oracle said recently that they plan to add 12 new data centers around the world to greatly enhance the performance of their own data centers to gradually reduce the huge gap between their cooperation with Amazon and other companies in the cloud infrastructure fields. The 12 locations are located in India, Japan, the Netherlands, Singapore, South Korea, Switzerland, the United States and Canada, of which the United States and Canada will build two data centers.

In addition, foreign media also said that Oracle will establish a new data center in China, located in Shenzhen, Guangdong, will cooperate with the local companies in accordance with the relevant foreign investment cooperation. Foreign media said Tencent is the most likely. In addition, Middle East Saudi Arabia also said it will attract Oracle to set up a new data center.

Don Johnson, a senior vice president at Oracle, said the company is also considering expanding beyond the 12 locations listed above. Running and maintaining a data center can cost quite a bit of money, and the maintenance costs for each data center are said to be hundreds of millions of dollars.

We all know how important to have enough storage for our data since the files now are both very massive. Except for the cloud storage and hard disk, the memory u disk is also very necessary since they are very convenient to use, easy to access and quite useful.
