Soldier Center Helmet Lab technology leads to revolutionary new combat helmet

Research performed in the Helmet Laboratory at the U.S. Army Combat Capabilities Development Command, or DEVCOM, Soldier Center has led to a revolutionary new combat helmet.To get more news about Hard Armor panels, you can visit bulletproofboxs.com official website.

Due to the Soldier Center’s Helmet Lab technology, and subsequent efforts working with key industry partners, the new combat helmets will provide the warfighter protection against a higher level threat – protection that previously could only be accomplished with a much heavier applique/helmet combination.

Researchers in the DEVCOM Soldier Center Helmet Laboratory have spent the past decade working to optimize combat helmet performance by developing new modeling, design and processing techniques. Combat helmets are comprised of flat sheets of ballistic material pre-formed into a helmet shape and then processed at a high temperature and pressure.

“Wrinkling and folds occur as the flat fabric conforms to the three-dimensional shape” said Jason Parker, a DEVCOM Soldier Center mechanical engineer. “These seams, wrinkles, and folds seriously degrade the ballistic performance, requiring more material and more mass to protect against a given threat. Through our research, we determined how these defects are introduced, how they affect ballistic performance, and how to eliminate them. The culmination of this research is a novel machine and process which produces a seamless, uniform helmet, free from defects such as folds and wrinkles.”

In 2015, the Helmet Laboratory developed a novel pre-form apparatus, process, and optimized helmet ply layup design. The Soldier Center used this technology to develop prototype helmets demonstrating breakthrough performance, providing a higher level threat protection that could previously only be achieved with the addition of a ballistic applique.

"In 2017, we tested prototype helmets targeting a higher level threat that were fabricated using our novel helmet preforming apparatus,” said Robert DiLalla, team lead of the Ballistic and Blast Protection Team in DEVCOM Soldier Center’s Soldier Protection Directorate. “The results far exceeded our expectation as we were getting stops well above the requirement and at 40 percent less weight than the current capability. The results were replicated with another batch of prototype helmets confirming that we had developed a new capability to significantly increase Soldier protection.”

Since 2017, the Helmet Laboratory, at the request of senior Army leadership, continued to mature and transition the technology to industry partners by establishing several Cooperative Research and Development Agreements, or CRADAs, and Research & Development contracts.

“After the Helmet Lab first demonstrated this breakthrough performance, the team worked diligently with our industry partners to rapidly transition this technology and contribute to the advancement from laboratory prototype to production ready helmets,” said David Colanto, PhD, who is the program manager for DEVCOM Soldier Center’s Integrated Multi-Threat Headborne System. “The collaborative effort with industry represents a successful technology transition and highlights the fact that Soldier Center applied research and technology demonstration efforts are critical to providing significant improvements to warfighter protection.”

In February 2021, Gentex Corporation announced that one of their Ops-Core® FAST Helmet Systems passed U.S. Government First Article Testing (FAT), a first for a helmet providing a higher level threat protection. This new helmet leverages helmet design and processing innovations transitioned through a CRADA with the DEVCOM Soldier Center's Helmet Lab.

“This new FAST helmet is the culmination of a multi-year commitment to innovate the novel production processes necessary to manufacture helmets with next-generation ballistic materials,” said Des Walsh, vice president of Advanced Research and Development for Gentex Corporation. “It serves as an excellent example of successful, outcome-oriented government-industry collaborative development, resulting in the most advanced ballistically protective helmet shell ever qualified for production by Gentex and available to the warfighter.”

China’s business confidence falls to lowest since January

Beijing (China), December 21 (ANI): A survey of sales managers showed that China’s business confidence fell to its lowest since January 2013, reflecting the impact of surging Covid-19 cases on economic activity with the abrupt lifting of many pandemic control measures.To get more china business market news, you can visit shine news official website.

Survey results were among the first indicators of how business sentiment has taken a hit in the world’s second-biggest economy, after the sharp relaxation of strict Covid containment measures on December 7 triggered a still-growing wave of domestic Covid cases across China. The World Economics’ survey was done on sales managers at over 2,300 companies and was conducted between December 1 and 16 this year.

China’s gross domestic product (GDP) is expected to grow just 3 per cent this year, its worst performance in nearly half a century, the survey said.

“The survey suggests strongly that the growth rate of the Chinese economy has slowed quite dramatically, and may be heading for recession in 2023,” World Economics said on Monday.

The survey showed business activity fell sharply in December with the sales managers’ indexes in manufacturing and service sectors both below the 50 level.

The London-based data provider said, “The percentage of companies that claim to be currently negatively impacted by Covid has risen to a survey high, with more than half of all respondents now suggesting their operations are being harmed in one way or another.”

According to World Economics, China has recently dismantled some key parts of the world’s toughest anti-Covid curbs and lockdowns. It said the measures were championed by President Xi Jinping but impaired the economy and sparked popular protests unprecedented in his decade-long rule.

The survey said the top leaders and policymakers would focus on stabilising the economy in 2023 and step up policy adjustments to ensure key targets are hit, according to an agenda-setting meeting ended on Friday. (ANI)

Chinese Alphabet From A To Z Description

The Chinese Alphabet, known as “Pinyin,” is the standard phonetic alphabet used in China. Pinyin uses all of the same Latin letters as the English alphabet except instead of “v” it uses “ ü.” A word of caution though - not every letter in Pinyin is pronounced the same way as the equivalent letter in the English alphabet! The chart above shows the initial and final sound combinations used in Pinyin. To get more news about china alphabet, you can visit shine news official website.
Chinese characters have existed for thousands of years. The earliest characters, or pictograms, often looked very similar to the items they represented. These characters eventually morphed into the less-pictographic logograms used today which often consist of phono-semantic compounds
Pinyin, on the other hand, is a fairly recent development. China adopted the current form of Pinyin in 1958. Foreigners, however, began developing their own forms of phonetic alphabets for Chinese as early as the turn of the 17th century.

The earliest known phonic alphabet was developed in the early 1600’s by a French missionary named Nicolas Trigault. He understood the Chinese language very well and in 1926 included his version of “Pinyin” in his book “Aid to the Eyes and Ears of Western Literati”
The Chinese government enlisted the help of various Chinese linguists in the 1950s to develop a more sophisticated phonic alphabet. The first version of this alphabet, which is now known as Pinyin, was published in 1958. It has been revised several times and is now used throughout schools in China as a tool to help students learn characters. It is also used in most other countries for the same reason.

How many Chinese characters and alphabet letters are there?

Chinese characters and the Pinyin alphabet are two separate and distinctive writing systems. There are over 50,000 Chinese characters in use and 26 letters in the Pinyin alphabet. These letters are used to create the 23 initial and 24 final sounds shown above.

What Is The Logic Of Chinese Characters?

While it may seem like all chinese characters are simply pictographs (characters derived from pictures), there are actually many types of characters - the least common of which is pictographs.

1. Pictographs ( xiàng xíng)

There are relatively few characters in use today which are considered pictographs. These are typically among the oldest Chinese characters still in use. The chart below shows some of the most common pictographic characters used today and how they have changed over time.
2. Determinative-Phonetic Characters (, xíngshēng)

These characters consist of two parts. One represents the sound, while the other indicates its meaning. Consider the following examples which all include the phonetic component 青 (qīng).
3. Ideographs (, zhǐ shì)

These are characters that express more abstract ideas with symbolic pictographs.These are a few common examples:
4. Combined Ideographs ( huìyì)

These are characters which consist of multiple pictographs or ideographs whose combined meaning alludes to the meaning of the new character. Here is a common example :
5. Transfer Characters (zhuǎnzhù)

These are characters which have the same meaning now due to sharing the same radical, having similar etymology, or a semantic drift. For example, the words 爸 (bà) and 父 (fù) share the 父 (fù) radical and both mean “father.” Another example are the words (kǎo) and (lǎo) which both mean “old.” These two characters were once the same character and together meant “elderly person.” They have since been separated and are both individually used to mean “old”.

Tesla to Add WiFi Garage Door Support in Upcoming Holiday Update

Christmas is almost here, so Tesla’s holiday update will soon be here. While many are still guessing what may be under the tree in this update, we now have word that Tesla will include support for MyQ accessories.To get more news about safe lock systems, you can visit securamsys.com official website.

MyQ lets you control supported garage doors, gates and lights over WiFi. Until now, users could only control MyQ devices from their smartphones, but Tesla is adding support for it to their vehicles.

Tesla Rumors Start Small
who is also the President and Founder of the Tesla Owners Club of Michigan, posted: Looks like MyQ support is coming to Tesla vehicles with software update 2022.44.25 :) I don't have any more detail than that.
If MyQ is indeed included in the holiday update, it will not only allow users to open or close their garage from the screen in the Tesla. MyQ also tells users if the garage is left open, it can control lights, access cameras, lock and unlock doors and use home intercoms. MyQ can also be scheduled to automatically close the garage every night at a certain time. The MyQ system is much more than a garage door opener.

MyQ is Considered the Best Garage Door Control
So why would this be better than HomeLink? That was a question repeated several times. MyQ is WiFi based so you can check in on it anywhere. There is also no need for the antenna. HomeLink is included with the Model S and Model X, but it's a $350 USD add-on for the Model 3 and Y.

Add MyQ Support to Existing Garage Doors
If you have an older garage door opener but still want to get in on MyQ, there is a MyQ device that, according to the company, makes any garage door opener a smart garage door opener. These are available at various retailers including Amazon, for roughly $20.
Integration
Tesla's integration of HomeLink into their vehicles is beautifully executed. You can have the vehicle automatically open or close your garage as you approach, never needing to touch a button. The vehicle uses your garage door's location and the vehicle's current position to determine when to open or close your garage door.

It's not clear whether Tesla will similarly integrate MyQ devices, but it certainly would make sense to have the ability to automatically trigger specific devices based on the vehicle's location. It could potentially open your garage door and turn on your hallway lights as you begin driving down your driveway.

Advantages Over HomeLink
MyQ support could have several advantages over HomeLink, besides being included for free. HomeLink currently requires proximity to the device to send the wireless signal, while MyQ could theoretically be executed anywhere in the world that has an internet connection.

Service robots provide a glimpse into the future

Robots are serving as samplers for nucleic acid testing (PCR), Peking Opera actors, coffee and ice cream makers, chess masters, and elderly care workers at the World Artificial Intelligence Conference (WAIC) in Shanghai.To get more news about GRS, you can visit glprobotics.com official website.

WAIC has evolved into a stage for demonstrating the capabilities of service robots and artificial intelligence, giving visitors a glimpse of what life will be like in the future.

Flexiv demonstrated its PCR robot, which features industrial-grade force control, computer vision, and other AI technologies, at its WAIC booth. It completes the sample-taking cycle within 28 seconds. In the future, it will be a new touch-less, safe, and efficient sampling method, but it still requires medical certification before being put on the market officially.
Flexiv's massage and therapy robot is also on display. It can do massaging tasks such as "pressing, pushing, and kneading muscles near the spine and waist."

ABB and Jaka showcased robots that could churn out ice creams and carry out other industrial tasks. HK-listed SenseTime's Xiangqi, or Chinese chess, master robot is a candy box-sized robot with 26 chess levels to match players of various skill levels. It is intended for children to learn tactics and to give company to the elders.
UBTech has introduced five service robots for elderly care, including intelligent mobility, box delivery, supported walking, and companionship. The company's smart old care services for the elderly community are currently available in Shanghai's Songjiang, Shenzhen, and cities in Shandong Province.

According to Tan Huan, co-chief technology officer at UBTech, the robots can serve as life care, security, memory care, and for spiritual requirements and medical rehabilitation. It is expected to play an important role in elderly care in the future.

It has huge market potential in China with its elderly care industry today accounting for 7 percent of national GDP.

According to the Chinese Institute of Electronics, the size of China's robot sector is forecast to reach US$17.4 billion by the end of 2022, with an annual average growth rate of 22 percent over the previous five years.

Fat or thin tires
Choosing between fat or thin tires on your new electric bike is a matter of personal preference. However, there are some benefits to either of these types of wheels.

Typically, fat tires are larger and provide better traction on both wet and dry surfaces. They also have an extra wide contact surface, which helps them get a solid grip on slippery or sloping terrain.

On the other hand, thin tires are lighter and more efficient. They are made from a smaller amount of rubber, which is why they are more cost effective to manufacture. Aside from their lightweight nature, they also have a less pronounced impact on your overall mileage.

While thin tires are less expensive and easier to ship, they don’t quite have the same traction as fat ones. The best way to judge which is the better tire for your riding style is to experiment with different air pressures.

Generally, a medium to high PSI is recommended for riding on pavement and loose snow. A lower PSI is ideal for riding on mud and gravel.

Powerful motor and large-capacity battery

eBike Maintenance 101: How to Take Care of My E-Bike

Everyone knows that for things to last a long time, you need to take proper care of them - your electric bike is no exception.To get more news about ebike maintaince, you can visit magicyclebike.com official website.

Your ebike, like anything else, needs proper care, thorough cleaning, and regular maintenance.
Cleaning and taking care of it regularly will keep it performing well, efficiently, and safely for a very long time - all of which can contribute to a longer lifespan for the battery and motor.To get more news about Fat Tire Electric Bikes, you can visit magicyclebike.com official website.

This guide goes through the exact steps of how to take care and look after your ebike, including tips and tricks on how to wash it, lubricate it, and take care of the battery.
How often should I service my electric bike?
Just like with any other means of transportation, the frequency of how often should you do checkups and servicing depends mostly on how often do you use it and how intensely.

Generally speaking, under normal circumstances, electric bikes which are used on a daily basis need routine checkup servicing once per year.
If you feel like you use your e-bike more often and it’s more of hard usage, you might want to do a checkup every 6 months or so.

We think it’s a good idea to give your e-bike a checkup once a year to ensure it's in working order. Otherwise, any potential issues may make themselves known once you start riding it through town, down the trail, or, worse yet, on your way to the beach (and who wants that?)..
Generally, you can maintain your bike chain at home by making sure its clean after using your ebike and keeping it lubricated with special gels and oils.
If you have a belt-drive electric bike (an alternative transmission system found on many newer ebikes), this would not be necessary.
First, we do not recommend using just the standard WD40 alone, because it is a penetrant, not a lubricant, and will dry out the chain. Instead, you should clean your chain with standard WD40, but you should also use a product like Tri-Flow, or the WD40 chain lubricant afterward, to make sure the chain is properly lubed too, not only cleaned.

How can I know when it’s done properly?

A properly lubed chain should not be dry when you touch it, but instead, it should be a little greasy - however, make sure not to over-lubricate it to the point where it is dripping lube. A properly lubricated chain will prevent rust and assist the movement of metal-on-metal parts.
If the derailleur is making noises, then the cable used to shift gears may require an adjustment, which, depending on the type of setup you have, may either be made at the derailleur or at the gear shifter at the handlebar mount - if you’re not familiar with it, we recommend going to your local bike shop, they’ll be able to help!

BEST ELECTRIC BIKE ACCESSORIES TO CONSIDER

Decking out your electric bike with accessories that make your rides and life easier is part of the fun of owning one. There are various things you can modify or update, but some of these accessories enhance your commutes. It’s essential to cater the additions to your needs and wants to optimize their purpose and maximize your bike’s usability. Let’s look at some common items people enjoy adding to their e-bike!To get more news about ebike accessories, you can visit magicyclebike.com official website.

Dry Pack
Some people love using their electric bikes as their everyday commuters—especially if they live in locations that have easy access to their primary locations, such as work, the gym, or school. But something that can happen along the way is inclement weather.To get more news about electric bike, you can visit magicyclebike.com official website.

Investing in a dry pack is the best way to ensure you’re ready for anything at any commute time. The QuietKat dry pack features a laptop-specific sleeve and helps keep all your electronics and belongings safe and dry. Visit a certified QuietKat dealer to snag yours!

Water Bottle Cage
Another necessary and common accessory is a water bottle cage. These allow you to place your water bottle in a convenient location to use while riding. This is a safer option than carrying water in your dry pack or cargo trailer because it allows you to drink on the move with easy access and motion control.

Bike Lights
Adding lights is not only smart, but it’s safe. For those who use their electric bike at varying times in the day, it’s hard to restrict your rides to daylight hours only. By adding lights, you can ensure you’re visible to motorists and that you can see the ground you’re riding on.

Handlebar Tape
Handlebar tape is an accessory not many remember for their electric bike, but it can create a firmer grip on the handlebars. Adding a new grip to the handlebars can help those who ride their e-bikes on varied terrain or inclement weather. One roll of tape will provide several passes on the bars, and you can retape as necessary.

Mini Tire Pump
A small accessory you can add to your dry pack is a mini tire pump. Because your electric bike houses a motor and battery power, keeping the tires at optimal PSI is vital in ensuring you receive the necessary output from the power sources. When the tires begin to dip low on air, your bike will work harder than it needs to.

What Kinds of Benefits Can I Expect From 3M VHB Tape?
There are a ton of benefits that come with using 3M VHB tape, with many more uses for it being created as it continues to makes its name in the industry. We'll just list a few of the most popular reasons here.To get more news about Glazing Tape, you can visit senpinghz.com official website.

1. IT'S ONE OF THE TOUGHEST THINGS OUT THERE
This point must be stressed first and foremost. 3M VHB tape offers one of the strongest bonds out of any adhesive. In fact, VHB has been certified in the industry to have a very strong bond (it's literally in the name). Its adhesive properties alone give it an incredibly durable hold on any surface, but combined with its elastic properties, it can absorb the shock of any load, making it perfect for both static and dynamic operations.

Furthermore, the powerful adhesive mix in the tape allows it to hold strong and hold long. 3M VHB tape can stay in place for many years and will continue doing its job just as well as it did the first time it was applied.

2. IT CAN WORK IN EXTREME TEMPERATURES
Every product has a limit to the hot or cold conditions it can work in, and the same goes for tape. Most adhesives have a limited temperature range, with their cool spectrum capping off at 10 degrees Celcius or 50 degrees Fahrenheit. 3M VHB double sided tape is much more durable, being able to on average take on freezing temperatures of 0 degrees Celcius or 32 degrees Fahrenheit.

3. THE TAPE CAN MOLD TO ANY SHAPE
You undoubtedly work with equipment that has a multitude of complex parts. More often than not, those parts are too challenging to fix properly with traditional adhesives, and fasteners have a fixed shape that may not completely fix the problem.

The VHB adhesive tape can make itself useful and fix any situation no matter what the matter is. The contouring abilities of the tape allow it to stretch, squeeze, and otherwise shape itself around any surface with ease, and its foam-based material helps it to flow into microscopic irregularities in the item and seal them all shut, guaranteeing a powerful and long-lasting bond.

4. YOU CAN'T SEE IT
No, seriously. When you use 3M VHB 5952 tape, you won't be able to see a thing after you've put it on. That's because the tape is designed to go virtually invisible after application, so you can get results that look as smooth as they are. It's just another way that 3M VHB goes the extra mile for the customers.

5. YOU CAN USE IT TO COMBINE DISSIMILAR MATERIALS
You may find yourself limited with traditional adhesives and fasteners in concerns to what you can use them on. In most cases, fasteners are designed to only fit a specific way in a specific material, and even though adhesives can be used on a decent range of surfaces, they are still limited to certain types of bonding due to the materials they may be made out of.

3M VHB tape has no limitations. VHB tape can not only fasten together almost any surface you can throw at it, but it can also hold together surfaces made from entirely different materials with absolutely no problem. Feel free to combine metal with wood, wood with plastic, or anything else your heart desires; the VHB tape will hold it together and offer you guaranteed security.

6. IT OFFERS DOUBLE THE POWER
The 3M VHB tape comes with not one, but two sides of adhesive sticking power, so you can get double the strength and double the power from every use. This means that it doesn't just cover up cracks or fasten small sections; the VHB tape can combine whole parts together using both of its sides, offering its strength to complete even the biggest projects.

How to Choose the Best Construction Tape for Vapor Barrier Seams

Over the past 40 years, a growing awareness of the importance of sustainability, reducing energy use, and creating healthy indoor spaces has prompted many changes in the building industry. To achieve these goals, contractors must aim to select methods and materials that produce tight building envelopes that will stop air and moisture infiltration.To get more news about Butyl Tape, you can visit senpinghz.com official website.

One method of achieving a tight building envelope involves continuous insulation (CI) across every structural member of the building, along with an application of an efficient vapor barrier sealed with a high-quality construction seaming tape.

Sealing the seams of the barrier with a high-performing tape helps to ensure a continuous air barrier that reduces moisture intrusion and accumulation into the wall system. CI and a properly sealed vapor barrier provide crucial components of an energy-efficient, durable, and healthy building.
With so many seam tapes on the market, choosing the best one can overwhelm builders. However, selecting the right tape makes a significant difference in energy efficiency, durability, and indoor air quality (IAQ). Today’s contractors can choose between three types of tape: asphaltic, rubber (butyl), and acrylic.

The original design of the rubber (butyl) construction seaming tape aimed to improve on asphaltic tape. The first rubber tape used natural rubber components. Today’s rubber tape, called butyl tape, uses a synthetic (elastomer) rubber. Butyl tape performs better in extreme temperatures, and it retains flexibility and durability over time compared to asphaltic tapes.

However, compared to acrylic seam tape, butyl tape can lose adhesion and discolor over time due to its intolerance to cold temperatures and UV rays.
Builders that use acrylic tape to seal the seams of a vapor barrier ensure a tight building envelope. A tightly sealed building envelope reduces energy use and moisture intrusion, which prevents the growth of mold. Mold can degrade the integrity of a building and create an unhealthy IAQ.

Contractors striving to keep up with increasing energy codes and demands for healthy indoor environments should switch to acrylic tape, like Barricade Seam Tape, for vapor barrier seams.
To meet the demands of today’s energy-efficient and healthy structures, builders must apply CI, along with an efficient vapor barrier system sealed with a high-quality construction seaming tape, like Barricade Acrylic Seam Tape. Sealing the seams of a vapor barrier system with Barricade Seam Acrylic Tape will ensure a tight continuous air barrier that reduces moisture intrusion and accumulation into the wall system. Please contact Barricade Building Products for more information on how to select the best construction tape for vapor barrier systems.
