Samsung CES 2023 TV Announcement

Published

 on

Samsung CES 2023 is officially underway, and Samsung is among the first brands to shed some light on the future of its TV lineup.

As is usually the case, product names, pricing, and specs have only partially been disclosed. But here’s a quick rundown of what we know, so far.

MicroLED CX

Last year at CES, Samsung unveiled a room-dominating 89-inch version of this TV to exist alongside its 99 and 110-inch MicroLED offerings. This week, Samsung officially announced a smaller, more consumer-friendly 76-inch option: the MicroLED CX.

But the CX is only “consumer-friendly” in the sense that its size is below 89 inches. In the past, these ultra-premium TVs have cost over $100,000 and required professional installation. The 76-inch CX will likely be more affordable, but still prohibitively pricey for most shoppers.

So, why all the hubbub? Well, MicroLED has long since been seen as the next big “thing” in the LED TV space. They feature modular blocks of tiny LEDs—even smaller than those found in a mini-LED TV. With millions of LEDs in play, the black levels of these TVs rival OLEDs, all the while getting as bright as some of the best LED TVs on the market.

A mind-bogglingly expensive, 76-inch TV may not seem like much to celebrate, but the CX is a marvel of engineering; it’s incredibly difficult to scale this technology down to commercial-friendly sizes like 55 or even 65 inches. The CX is the next step toward a possible future where MicroLED technology reigns supreme.

The next generation of Samsung QD-OLED will be available in a 77-inch model.

Last year, the Samsung S95B blew us away by blending the benefits of a traditional OLED display with quantum dot technology. Its perfect black levels, dazzling color, and class-leading brightness amounted to one of the best pictures we’ve ever seen on a TV. This year, Samsung is bringing QD-OLED technology back with the S95C, and according to Samsung, it’s even brighter than last year’s QD-OLED TV.

Additionally, while last year’s model was limited to just two size options (55 and 65 inches), the S95C will be available in an additional 77-inch model. It’ll sport a 144Hz gaming refresh rate and AMD FreeSync Premium Pro certification, building on the gaming strengths of its predecessor.

Neo QLED TVs

The Samsung QN95C is the company’s 4K Neo QLED flagship for 2023.

Samsung described the 4K Neo QLED family of TVs as being the backbone of its TV lineup this year, as their performance makes them suitable for all lighting conditions. Historically, Samsung’s Neo QLED TVs have offered a tremendously bright, color picture capable of cutting through sunlight or intense ambient light. At CES, Samsung unveiled the next generation of Neo QLED offerings, including the QN95C, the QN800C, and the QN900C (the latter two being 8K sets).

Neo QLED combines mini-LED backlighting with brightness- and color-boosting quantum dots. The result is a searingly bright picture with excellent contrast control—two things we’re hoping to see from these new TVs.

Samsung Health Monitor

With Samsung Health Monitor, a slim camera connected to a supported TV will track various aspects of your health in real time.

One of the more surprising announcements from Samsung this year wasn’t a TV at all. Samsung’s Health Monitor is making its way to a selection of Samsung smart TVs in 2023, including the QN95C.

Health Monitor is an easy-to-use, in-home health management app that uses a TV-connected webcam to track heart rate, respiratory rate, oxygen saturation, and more—all while you’re watching TV. According to Samsung, the system uses something called remote photoplethysmography (rPPG), an “intelligent camera/computer vision technology that estimates vital signs by detecting changes in facial skin color caused by heartbeats.” It’s described as an easy, fuss-free way to monitor your health from home, and it’s entirely optional.

Samsung already confirmed that its 4K, Neo QLED flagship, the QN95C, will ship with the slim fit camera required to take advantage of Health Monitor. It’s not yet clear if any additional models will ship with a camera.

A Quick Guide to Better CMM Maintenance

Published

 on

CMM

A coordinate-measuring machine, also known as a CMM, is a specialized piece of equipment common in high-precision manufacturing. It uses coordinate technology to measure and replicate the dimensions of particular objects.

CMMs are a lot more accurate than regular measurement gauges. This characteristic makes them the equipment of choice for quality assurance in certain industries, like aerospace, defense, and medical manufacturing.

Despite being a powerful piece of equipment and the most versatile measuring tool in the metrology industry, CMMs can also be quite delicate. They require the right environment and proper maintenance practices to maintain accuracy and reliability.

The Importance of Proper CMM Maintenance

It’s essential to clean and inspect each part of your machine to ensure it stays efficient and accurate. Preventative maintenance ensures that your CMM remains accurate and performs at its best. It also improves your machine’s longevity.

300x250x1

Without proper CMM maintenance, you could risk damaging your CMM. Repairs would involve operational delays and additional costs.

CMM Preventative Maintenance Tips

Preventative maintenance practices are ones your team could do by yourselves. It’s best to schedule regular maintenance checks for your CMM daily, weekly, monthly, or quarterly. These checks can alert you immediately to possible problems with your CMM.

Remove dust and dirt regularly

Clean and well-maintained air bearings ensure your CMM works as it should. These frictionless and stable bearings help ensure accuracy and efficiency. Dust and dirt can clog your machine’s air bearings, affecting its overall performance.

Aside from your machine’s air bearings, dust could also get into other surfaces and crevices. These tiny particles could affect your machine’s accuracy.

Handle Stylus Tips Properly

The stylus is the tip that makes contact with the object you want to measure with your CMM. Despite this significant role, the stylus can be fragile and require careful handling. Too much force could cause it to bend or break.

Clean your stylus with a cleaning agent and a lint-free cloth. Make sure to remove any residue from workplace materials.

Ensure Good Air Quality

Most CMMs use air bearings, and good air quality is essential to keep them running smoothly. Various air quality issues could affect machine performance and even burn out machine motors.

For air quality maintenance, ask and address the following questions:

  • Do the lines have condensation, oil, or other contaminants?
  • Is the airflow constant?
  • Are you using the proper pressure?

When To Call a Professional

Most preventative maintenance practices are simple enough to be performed internally. However, some issues require professional attention. You can also conduct regular professional maintenance checks to ensure you don’t miss anything.

Below are some procedures that require professional assistance. Many CMM suppliers also offer maintenance services alongside their machinery.

Conducting CMM Training

CMMs are highly specialized pieces of equipment. To handle them properly, your staff needs professional training.

Training courses allow you to get trained by CMM experts on the tools and knowledge necessary within your industry. Regular training sessions also help keep you updated on industry trends and standards.

Sensor Malfunctions

CMM sensors are critical to your machine’s speed and accuracy. They should be professionally inspected and calibrated annually.

Routine sensor maintenance can significantly improve the efficiency and accuracy of your machine. CMM sensors include the following:

  • Scanning probe
  • Single point laser
  • Line laser
  • Electronic touch trigger probe
  • Video camera

Faulty Bearings

Neglected air bearings could cause them to falter in their accuracy and stability. Properly maintained air bearings ensure a smooth, stable, and accurate measurement process.

A professional metrology company can thoroughly inspect your air bearings to prevent further machine damage.

A CMM is a significant investment for any business. Good maintenance practices help your machine last and perform at its best, thus making the most out of this investment.

Nintendo’s discounted Switch game vouchers are back

Published

 on

Nintendo’s Switch Online service has become a better deal over time, offering more perks than just the ability to play games online. On top of getting access to SNES and NES classics, and cloud save backups (for most games, save a couple dozen), Nintendo announced an even bigger perk yesterday: discounted game vouchers.

All subscribers can buy a two-pack of these vouchers for $99.98, and a huge range of first-party (in other words, typically discount-averse) Nintendo games are looped in. I encourage you to check out the full list, but some highlights include the brand-new Fire Emblem Engage, Kirby’s Return to Dream Land Deluxe, Bayonetta Origins: Cereza and the Lost Demon, Metroid Dread, Splatoon 3, The Legend of Zelda: Breath of the Wild, and Pokémon Scarlet and Violet. Important note: you both have to be a subscriber to buy and use these vouchers.

It’s great that this list is more expansive than Nintendo’s first swing at this deal in 2019. But this perk could actually turn Switch Online into a must-have service because it allows you to pre-purchase up to four sets of vouchers (totaling eight games), and keep them for 12 months from the date of purchase. With $20 in savings with each pair of vouchers, buying four bundles will save you up to $80, assuming that each title normally costs $59.99. If you buy a lot of games, this is a smart way to save a little bit of money on every forthcoming purchase.

I know what you might be thinking: “Can I use one on The Legend of Zelda: Tears of the Kingdom?” Nintendo has not currently listed the deliriously anticipated sequel to Breath of the Wild, which is set to release on May 12th, 2023. Polygon has reached out to Nintendo to see if it’ll eventually become eligible, but did not hear back in time for publication.

You can get a free seven-day trial for Switch Online here, and you can easily subscribe to the service directly from the Switch’s eShop (it costs $3.99 per month, $7.99 for three months, or $19.99 per year). However, you can purchase (or gift) a one-year subscription with a digital code via Best Buy for $19.99. With a family subscription that costs $34.99 per year, up to eight Switch accounts can reap the perks of Switch Online.

For players who want all the perks, access to Goldeneye 007 and other N64 and Sega Genesis games, and complimentary DLC for some Switch games like Mario Kart 8 Deluxe, you’ll need Nintendo’s Switch Online plus the Expansion Pack tier, which costs $49.99 per year for one account, or $79.99 per year for a family subscription.

Canadian discovery could help batteries last longer

Published

 on

A chance discovery in a Canadian laboratory could help extend the life of laptop, phone and electric car batteries.

According to scientists from Dalhousie University in Halifax, common adhesive tape in batteries may be the reason many devices lose some of their power while off or not being used, which is a phenomenon known as self-discharge.

“In our laboratory we do many highly complex experiments to improve batteries, but this time we discovered a very simple thing,” Michael Metzger, an assistant professor in Dalhousie University’s physics and atmospheric science department, said in a news release. “In commercial battery cells there is tape—like Scotch tape—that holds the electrodes together and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge.”

The solution is simple, too, Metzger says: replace the polyethylene terephthalate, or PET, plastic tape commonly used inside batteries with something more durable and stable.

300x250x1

“It’s a commercially relevant discovery,” Metzger said. “It’s a small thing but it can definitely help improve battery cells.”

Metzger and his team have been trying to understand why lithium-ion battery cells in inactive devices tend to lose some of their power and self-discharge, something that has long frustrated consumers and manufacturers alike.

“Every manufacturer of lithium-ion cells in the world wants to make self-discharge as small as possible,” Metzger told CTVNews.ca in a joint statement with graduate student Anu Adamson. “In every battery there is a small rate of self-discharge that slowly drains the battery. This is very inconvenient for users and a big headache for industry.”

The electrodes that power batteries are separated by an electrolyte solution that is usually a form of lithium. After exposing several battery cells to different temperatures, researchers were surprised to see that electrolyte solution had turned bright red when it normally should be clear, which was something they had never encountered. The discovery was made by Adamson and two other students.

Chemical analysis of the red electrolyte solution revealed that at higher temperatures, a new molecule had been created inside the battery through the decomposition of common PET adhesive tape, which is often used to hold components together inside batteries. Strong and lightweight, PET is also frequently used for plastic packaging, drink bottles, clothing fibres and more.

Researchers realized that the red molecule, dimethyl terephthalate, was acting as a redox shuttle, meaning that it can transport electrons between a battery’s positive and negative electrodes, creating self-discharge and depleting power even when a battery is not in use. Ideally, the shuttling of electrons within a battery should only happen when a device is on.

“It’s a very simple thing—it is in every plastic bottle and no one would have thought that this has such a huge impact on how the lithium-ion cells degrade,” Metzger said in the news release. “It’s something we never expected because no one looks at these inactive components, these tapes and plastic foils in the battery cell, but it really needs to be considered if you want to limit side-reactions in the battery cell.”

The findings are outlined in a pair of studies published on Jan. 20 and Jan. 23 in the peer-reviewed Journal of The Electrochemical Society. The researchers are now testing PET tape substitutes.

“Since the PET in the tape is the culprit that creates the redox shuttle, we need to replace it with a polymer that is more stable and does not decompose in the harsh chemistry of a lithium-ion battery,” Metzger and Adamson told CTVNews.ca. “So far, the results look very promising, and we plan to publish a new research paper on improved polymers for lithium-ion battery tapes soon.”

According to the researchers, their work has been attracting interest from “some of the world’s largest computer hardware companies and electric vehicle manufacturers,” which are eager to reduce self-discharge and improve battery performance.

“We visited some of these companies and they are planning to implement more stable polymers in their battery cells,” Metzger said.

In the release, Metzger noted: “One of the engineers said, ‘I heard you guys found out something is wrong with PET tape.’ So, I explained to him that it’s causing this self-discharge and asked him, ‘What are you using in your cells?’ He said, ‘PET tape.'”
