What should we do in the face of COVID-19

图片
Facing COVID-19, the first thing we need to do is not to panic and maintain a good attitude. Then find a way to deal with it. ​ As we all know, COVID-19 is mainly transmitted through droplets and contact, so as long as we mainly prevent these two modes of transmission, we do not need to panic. First of all, wear a mask when going out to avoid unnecessary going out. If you go out, avoid crowded places and keep a safe distance from others, do not take off the mask casually outside, cover with tissue paper when sneezing Mouth and nose, do not throw away used paper towels. When you return, first dispose of the masks, and it is best to wrap them in plastic bags, and put them in garbage bins. Then wash your hands in seven steps. If you are not sure, you can disinfect the room with disinfectant water and 75% alcohol. Note that alcohol is flammable and should be used safely. If you don't go out at home, you don't need to disinfect the room twice a day. Keep it clean and tidy a

how to wear medical masks

Now that the coronavirus is getting worse, Yahui reminds you to go out and remember to wear a mask, because the person you meet on the street, you do n’t know if he is infected with the  coronavirus , and if we wear a mask, we can effectively prevent Likely to be infected. ​ Before putting on a mask, clean hands with alcohol-based hand rub or soap and water. Cover mouth and nose with mask and make sure there are no gaps between your face and the mask. Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water. Replace the mask with a new one as soon as it is damp and do not re-use single-use masks. To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water. Yeahui is a connector supplier with 11 years of experience in developing high quality connectors and wiring harnesses. wo have many types of products, i

Why is artificial intelligence important

图片
AI  automates repetitive learning and discovery through data. But AI is different from hardware-driven, robotic automation. Instead of automating manual tasks, AI performs frequent, high-volume, computerized tasks reliably and without fatigue. For this type of automation, human inquiry is still essential to set up the system and ask the right questions. ​ AI adds intelligence to existing products. In most cases, AI will not be sold as an individual application. Rather, products you already use will be improved with AI capabilities, much like Siri was added as a feature to a new generation of Apple products. Automation, conversational platforms, bots and smart machines can be combined with large amounts of data to improve many technologies at home and in the workplace, from security intelligence to investment analysis. AI adapts through progressive learning algorithms to let the data do the programming. AI finds structure and regularities in data so that the algorithm acquires a

About the Coronavirus COVID-19

It can take up to 14 days for symptoms of coronavirus to appear. They can be similar to the symptoms of cold and flu. If you have any of the symptoms of coronavirus, you should behave as if you have the virus and self-isolate for 14 days. People in your household will need to restrict their movements. Coronavirus is spread in sneeze or cough droplets. To infect you, it has to get from an infected person's nose or mouth into your eyes, nose or mouth. ​ It’s important to wash your hands properly and often. To help stop the spread of coronavirus you may need to either restrict your movements or self-isolate. Restricted movements means avoiding contact with other people and social situations as much as possible. You will need to do this if you are a close contact of a confirmed case of coronavirus and you are still well. Self-isolation means staying indoors and completely avoiding contact with other people. You will need to do this if you have symptoms of coronavirus.

Responding to COVID-19

Protect your employees. The COVID-19 crisis has been emotionally challenging for many people, changing day-to-day life in unprecedented ways. For companies, business as usual is not an option. They can start by drawing up and executing a plan to support employees that is consistent with the most conservative guidelines that might apply and has trigger points for policy changes. Some companies are actively benchmarking their efforts against others to determine the right policies and levels of support for their people. Some of the more interesting models we have seen involve providing clear, simple language to local managers on how to deal with COVID-19 (consistent with WHO, CDC, and other health-agency guidelines) while providing autonomy to them so they feel empowered to deal with any quickly evolving situation. This autonomy is combined with establishing two-way communications that provide a safe space for employees to express if they are feeling unsafe for any reason, as well as mo

COVID-19 irreversible globalization

The sudden emergence of the new crown pneumonia epidemic has pressed the pause button for most industries in the world, unable to supply, and lack of demand, making some enterprises unable to operate normally. Governments of various countries have adopted relevant policies to help companies avoid bankruptcy, but they are not enough to provide business expansion . The impact on the global supply chain during the new crown pneumonia epidemic exposed the risk that most companies are too dependent on one or two major supply sources. The epidemic will prompt some companies to re-evaluate their supply chains, or to establish more flexible supply chains to find more suppliers for the same products, in order to reduce the losses caused to enterprises during emergencies. However, the global supply chain is a complex system, and its formation and change are a long-term process. Today's global supply chain is difficult to be overturned by an epidemic. The situation of the global decentraliza

What about the new coronavirus COVID-19

The advice many people will hear now is to be more ventilated, wash your hands frequently, avoid partying, and wear a mask. why? Because now the world is suffering from the new coronavirus COVID-19. What is a coronavirus? Coronavirus can cause respiratory infections in humans. The previous case was SARS, now called COVID-19. Its main transmission method is coughing and sneezing between people, close contact with infected people or contact with infected surfaces. Then spread through mouth, nose or eyes. Coronavirus can produce a range of symptoms, including fever, cough, shortness of breath, sore throat, and runny nose. When you encounter these symptoms, don't be nervous. You will not know the results until you go to the hospital for an examination. It may be just a common disease. ​ New coronavirus outbreaks occurred in Wuhan, China, and in the face of this situation, the Chinese people are always positive. Because the new coronavirus is transmitted through the mouth, nose, or

Amazon bans unnecessary items in its warehouse

图片
Amazon is banning its warehouses from stocking nonessential items during the coronavirus pandemic. The online retail giant is placing restrictions on the types of merchandise it will carry in its warehouses through April 5. Faced with merchandise shortages in the United States and Europe due to the Covid-19 coronavirus pandemic, Amazon has instituted sweeping changes on which products it will store and ship from its warehouses over the next three weeks, in a move it said was aimed at keeping essential items in stock and speeding up orders. ​ Early Tuesday morning, Amazon said it would be “temporarily prioritizing household staples, medical supplies, and other high-demand products coming into our fulfillment centers so that we can more quickly receive, restock and deliver these products to customers.” By “prioritizing,” Amazon means it will no longer accept new shipments to its warehouses for discretionary items through April 5. During that time, Amazon will continue to sell al

​Artificial Intelligence Drives Autonomous Cars

图片
For an automobile to be autonomous, it needs to be continuously aware of its surroundings—first, by perceiving (identifying and classifying information) and then acting on the information through the autonomous/computer control of the vehicle. Autonomous vehicles require safe, secure, and highly responsive solutions which need to be able to make split-second decisions based on a detailed understanding of the driving environment. Understanding the driving environment requires an enormous amount of data to be captured by myriad different sensors across the car, which is then processed by the vehicle's autonomous driving computer system. ​ For the vehicle to be truly capable of driving without user control, an extensive amount of training must be initially undertaken for the Artificial Intelligence (AI) network to understand how to see, understand what it's seeing, and make the right decisions in any imaginable traffic situation. The compute performance of the autonomous car

What does a world with self-driving cars look like

图片
Companies continue to invest despite the setbacks because self-driving cars, when they happen, will change a lot for the world — and make their creators lots of money. Many consumers will want to upgrade. Imagine being able to read or doze off during your morning drive to work or on long car trips. It also seems likely that taxi and ride-hailing companies will offer self-driving cars, rather than paying drivers (in fact, companies like Uber are betting on it). Self-driving cars should also make a huge difference for Americans with disabilities, many of whom can’t get a driver’s license and have trouble getting to work, the store, and doctor’s appointments. ​ Experts disagree on whether self-driving cars will change anything fundamental about car ownership in America. Some argue that people won’t need to own a car if they can order one on their phone and get a timely robot ride anywhere. Others have pointed out that people generally still own a car even in areas with good ride-

How exactly do self-driving cars work

图片
Engineers have been attempting prototypes of self-driving cars for decades. The idea behind it is really simple: Outfit a car with cameras that can track all the objects around it and have the car react if it’s about to steer into one. Teach in-car computers the rules of the road and set them loose to navigate to their own destination. ​ This simple description elides a whole lot of complexity. Driving is one of the more complicated activities humans routinely do. Following a list of rules of the road isn’t enough to drive as well as a human does, because we do things like make eye contact with others to confirm who has the right of way, react to weather conditions, and otherwise make judgment calls that are difficult to encode in hard-and-fast rules. John Krafcik, CEO of Waymo, presents a self-driving car at Wed Summit in Lisbon, Portugal, on November 7, 2017. And even the simple parts of driving — like tracking the objects around a car on the road — are actually much trickie

How 5G and IoT will affect the auto industry

图片
Autonomous cars (and other vehicles, such as trucks) may still be years away from widespread deployment, but connected cars are very much with us. The modern automobile is fast becoming a sensor-laden mobile Internet of Things device, with considerable on-board computing power and communication systems devoted to three broad areas: vehicle location, driver behaviour, engine diagnostics and vehicle activity (telematics); the surrounding environment (vehicle-to-everything or V2X communication); and the vehicle's occupants (infotainment). All of these systems use cellular -- and increasingly 5G -- technology, among others. Although 5G networks are still a work in progress for mobile operators, the pace of deployment and launches is picking up. By the end of 2019, according to the GSA (Global mobile Suppliers Association), 61 operators in 34 countries had launched one or more 3GPP-compliant 5G services. Of those, 49 operators had launched 5G mobile services, while 34 had launched

The impact of 5g and iot on smart cities

图片
Smart cities is another sector already benefiting from the impact of  5G  and  IoT .   "I used to have a guy come and measure my water meter manually; now they're installing systems so that you can do this remotely," said iBASEt's Poonian. "With my gas meter, I'm now starting to get data analytics on how I'm performing against my peers and trying to create cost-saving programs." ​ While that's a current use case, IoT endpoints will become even more powerful with 5G connectivity, allowing for more insights across greater distances. For example, using crowdsourced information, the technology can evaluate traffic patterns throughout the city and direct crowds to open parking garages via apps in their cars, Patron said. "Think of silly situations like big football games where everyone is struggling to find a parking place, particularly in city centers where there's not a lot of parking," Patron said. "Or think of much more

Internet of Things and 5G

图片
IoT devices use a variety of methods to connect and share data, although most will use some form of wireless connectivity: homes and offices will use standard Wi-Fi, Zigbee or Bluetooth Low Energy (or even Ethernet if they aren't especially mobile); other devices will use LTE (existing technologies include Narrowband IoT and LTE-M, largely aimed at small devices sending limited amounts of data) or even satellite connections to communicate. However, the vast number of different options has already led some to argue that IoT communications standards need to be as accepted and interoperable as Wi-Fi is today. ​ One area of growth in the next few years will undoubtedly be the use of 5G networks to support IoT projects. 5G offers the ability to fit as many as one million 5G devices in a square kilometre, which means that it will be possible to use a vast number of sensors in a very small area, making large-scale industrial IoT deployments more possible. The UK has just started a tr

What about privacy and the Internet of Things

图片
With all those sensors collecting data on everything you do, the IoT is a potentially vast privacy and security headache. Take the smart home: it can tell when you wake up (when the smart coffee machine is activated) and how well you brush your teeth (thanks to your smart toothbrush), what radio station you listen to (thanks to your smart speaker), what type of food you eat (thanks to your smart oven or fridge), what your children think (thanks to their smart toys), and who visits you and passes by your house (thanks to your smart doorbell). While companies will make money from selling you the smart object in the first place, their IoT business model probably involves selling at least some of that data, too. ​ What happens to that data is a vitally important privacy matter. Not all smart home companies build their business model around harvesting and selling your data, but some do. And it's worth remembering that IoT data can be combined with other bits of data to create a s

What about Internet of Things security

图片
Security is one the biggest issues with the IoT. These sensors are collecting in many cases extremely sensitive data -- what you say and do in your own home, for example. Keeping that secure is vital to consumer trust, but so far the IoT's security track record has been extremely poor. Too many IoT devices give little thought to the basics of security, like encrypting data in transit and at rest. ​ Flaws in software -- even old and well-used code -- are discovered on a regular basis, but many IoT devices lack the capability to be patched, which means they are permanently at risk. Hackers are now actively targeting IoT devices such as routers and webcams because their inherent lack of security makes them easy to compromise and roll up into giant botnets. Flaws have left smart home devices like refrigerators, ovens, and dishwashers open to hackers. Researchers found 100,000 webcams that could be hacked with ease, while some internet-connected smartwatches for children have bee

the benefits of the Internet of Things for consumers

图片
The IoT promises to make our environment -- our homes and offices and vehicles -- smarter, more measurable, and... chattier. Smart speakers like Amazon's Echo and Google Home make it easier to play music, set timers, or get information. Home security systems make it easier to monitor what's going on inside and outside, or to see and talk to visitors. Meanwhile, smart thermostats can help us heat our homes before we arrive back, and smart lightbulbs can make it look like we're home even when we're out. ​ Looking beyond the home, sensors can help us to understand how noisy or polluted our environment might be. Self-driving cars and smart cities could change how we build and manage our public spaces. For consumers, the smart home is probably where they are likely to come into contact with internet-enabled things, and it's one area where the big tech companies (in particular Amazon, Google, and Apple) are competing hard. The most obvious of these are smart spea

​What is an example of an Internet of Things device

图片
Pretty much any physical object can be transformed into an IoT device if it can be connected to the internet to be controlled or communicate information. ​ A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. An IoT device could be as fluffy as a child's toy or as serious as a driverless truck. Some larger objects may themselves be filled with many smaller IoT components, such as a jet engine that's now filled with thousands of sensors collecting and transmitting data back to make sure it is operating efficiently. At an even bigger scale, smart cities projects are filling entire regions with sensors to help us understand and control the environment. The term IoT is mainly used for devices that wouldn't usually be generally expected to have an internet connection, and that can communicate with the network independently of human action. For this reason, a PC i

The Internet of Things

图片
What is the Internet of Things? The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data. Thanks to the arrival of super-cheap computer chips and the ubiquity of wireless networks, it's possible to turn anything, from something as small as a pill to something as big as an aeroplane, into a part of the IoT. Connecting up all these different objects and adding sensors to them adds a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate real-time data without involving a human being. The Internet of Things is making the fabric of the world around us more smarter and more responsive, merging the digital and physical universes. ​ The application field of the Internet of Things involves all aspects, making limited use of resources more rationally allocated, thereby improving industry efficiency and effectiveness. The applications

production reliability of the connector

图片
Connectors need to undergo a pair of processes in the production process, so we need to carry out strict standards for each process to ensure the production reliability of the connector. ​ Process reliability The processing technology of the shell, the injection molding and gluing of the insulator, the molding and gold plating of the contacts, the assembly process of the electrical connector, and the termination of the cable are all important to the inherent reliability of the product. Gold-plated contact parts are manually barrel-plated, which often results in the inner wall of individual jacks being partially without a coating and showing an oxidized color. Ultrasonic gold-plating production lines are introduced, and the thickness of the gold-plating layer is strictly monitored with instruments to form a uniform film on the inner wall, which improves contact reliability. Test reliability The electrical connector is strengthened in all key processes, and strict products a

Design reliability of the connector

图片
Connectors are important components of various electrical systems and are mainly responsible for signal and power transmission. The importance is self-evident, so we need to put their reliability first when designing connectors. So where does the design reliability of the connector manifest itself? ​ Reasonable selection Material selection is an important prerequisite to ensure the electrical performance and reliability of the electrical connector. The material used in the electrical connector determines the upper limit of the operating temperature, and the decisive factor is the insulating material, the sealing material used for the environmentally sealed electrical connector, the adhesive material, the shell Body and contact materials. Material selection involves the mechanical, electrical, environmental and other performance requirements of the connector and the physical and chemical properties of the material itself. Among them, the thermal properties of materials (heat-resi

What to pay attention to when producing terminal connectors

图片
The current terminal connector applications are very common, especially in the industrial field. Different types of terminal connectors have different application requirements. There are also factors that need to be kept in mind when producing terminal connectors. ​ You should know that the terminal is an accessory product for industrial production of electrical components. Its main function is to facilitate the connection of wires. Therefore, it is also divided into the scope of connectors in the process of industrial development, and it also becomes a terminal connector, which means that it functions An important part of industrial production plays the role of a connector, which is not only convenient for production, but also conducive to improving production efficiency as the main purpose. In addition, according to the process of industrialization, wire connections and signal transmission have already been realized. But how can the transmission process be guaranteed? That is

Improve connector performance

图片
For connector manufacturers, in addition to their productivity, they also care about the quality of their products. When it comes to product quality, many aspects are involved, such as the problem of high-speed micro-pitch interconnect performance of connectors. Do you know how to improve this performance of the product? ​ 1. For connector products, in the early stages of design, multiple simulation cycles are performed to accurately quantify product performance before starting expensive processing. 2. When mating the connector, minimize stubs in the contact area. The longer the stub, the better the reliability, but the stub is an electrical load like an antenna. 3. Simplify contact points and improve signal path performance. 4.Short lead length to reduce signal loss 5. Add asymmetric footprints and contacts as much as possible, because the alternating design reduces the pair-wise crosstalk between pin rows and rows. 6. Optimize the connector branch area (BOR). Think of

Common insulation materials

图片
When using connectors, we have given the most consideration to safety, because if an accident occurs and the consequences are serious, a fire will occur. Therefore, in the manufacturing process, we need to consider the insulation material of the connector. There are three types of insulation materials that are more commonly used. ​ PBT material, generally used PBT material is added with 20% to 30% glass fiber, has the ability to resist cracking impact, anti-electricity, good abrasion resistance, low friction coefficient, good lubrication effect, oil and chemical resistance Good drug properties. It still has good dielectric strength under high temperature and high humidity. Its shrinkage ratio is between about and 60 ° C. Its temperature resistance is about degree. It has good moldability and flame resistance. Most of the plastic materials of current connector manufacturers choose PBT This plastic. ABS material, it has good impact toughness, oil resistance, abrasion resistance, r
