| The first PlayStation 5 teardown reveals some hardware secrets - Ars Technica Posted: 07 Oct 2020 07:32 AM PDT 
We're still a bit over a month away from the official launch of the PlayStation 5, but we've already got the first public teardown of the console hardware courtesy of Sony itself. The Japanese video (with English subtitles) Sony posted Wednesday morning answers quite a few nagging questions left from previous announcements and recent hands-on time from some Japanese press. Chief among them is a demonstration of how the system's circular black stand works. When the PS5 is placed vertically, the stand is held in place with a single large screw. When that screw is removed, it can be stored in a compartment in the base, and a small cap fills in the screw hole in the system itself. PS5 owners will use the same base when placing the PS5 horizontally, seemingly to give a flat surface for the system's gentle curves to rest on. In this configuration, though, the base simply snaps into place along a set of marks on one of those white panels, no screw required.Speaking of those white panels, the teardown video shows that they can be popped off easily without tools. Just "lift the back corner and slide it off," as the video explains it. With the white panels off, users get easy access to the outside of the system's cooling fan, which draws in air from both sides of the system through two long side vents on the front and a rear vent that runs the entire length of the system. The inner shell also features two "dust catcher" holes that can be easily vacuumed out, according to Sony. That should be welcome news for PS4 owners who have gotten used to tearing open the system and blasting it with canned air to remove system-clogging dust.

You'll need a screwdriver to remove the small panel that protects this slot, but otherwise it seems relatively easy to access, especially compared to the internal storage on previous PlayStation consoles. The system's 825GB of built-in high-speed storage is contained on a separate custom-controlled chip directly on the motherboard, though.
A few other interesting tidbits revealed in the teardown:

| Intel confirms 11th-gen 'Rocket Lake' desktop CPUs for early 2021 - Engadget Posted: 07 Oct 2020 09:29 AM PDT If you're looking to upgrade your rig or pick up a new desktop, it may be worth waiting until next year. In a Medium post, Intel has confirmed that its 11th generation "Rocket Lake" CPUs will be arriving in the first quarter of 2021. They'll also finally match AMD's third-generation Ryzen chips with PCIe 4.0 support. Clearly, Intel is trying to splash a bit of cold water on AMD's Ryzen 5000 CPUs, which are launching tomorrow and will serve as Rocket Lake's main competitor. Intel's confirmation comes a day after Videocardz reported on some key rumors about the Rocket Lake CPUs. The site claims they'll launch in March, feature a faster "Cypress Cove" core architecture, and max out with an 8-core offering. The latter would be surprising since Intel's Comet Lake S chips topped out with a 10-core CPU. Judging from some early GeekBench scores, Wccftech predicts these new chips will be an evolutionary leap ahead of the 10th-gen CPUs. They'll reportedly have a 5GHz boost speed and be Intel's farewell to its aging 14nm architecture. |
| Why Apple needed the FDA to sign off on its EKG but not its blood oxygen monitor - The Verge Posted: 07 Oct 2020 09:25 AM PDT  During the announcement of the Apple Watch Series 6, the company heralded the newest element — a blood oxygen monitor — as an addition to its existing slate of health features. "Apple Watch is already a powerful health tool with apps that measure heart rate and heart rhythm," said Sumbul Ahmad Desai, Apple's VP of health. "And now adding blood oxygen brings in another valuable health measurement to users." The features on the Apple Watch that track heart rate and heart rhythm, though, have a key difference from the blood oxygen monitor: the heart-tracking features are cleared by the Food and Drug Administration (FDA), and the oxygen monitor is not. Apple went through a long, extensive process to develop and validate an EKG feature so that the watch could detect a condition called atrial fibrillation. It didn't need to do the same thing for the pulse oximeter. Blood oxygen monitors, or pulse oximeters, are considered Class II medical devices by the FDA. Generally, any company that wants to sell one in the United States has to submit documentation to the agency confirming that its product works just as well as other versions of the same product already on the market. There's a workaround, though: if the company says that the product is just for fun, or for general "wellness," they don't have to go through that process. They can't claim that it can diagnose or treat any medical conditions, but they can put it up for sale. That's the route Apple went down. They're not saying that their monitor can diagnose any disease, just that it's offering up the information. Other health-focused apps and smartwatches have taken the same approach, sidestepping the FDA process. "If you're just providing information, they're not regulating that," says Matt Grennan, assistant professor of health care management in the Wharton School at the University of Pennsylvania. Digital health products are so ubiquitous, and so many new ones enter the market every year, that it'd be hard for the FDA to review all of them. "They have to think about how they can allocate their own resources," Grennan says. The agency does step in, though, when companies want to use apps to influence the medical care someone receives. The EKG feature falls under that category. It's supposed to serve a specific medical purpose: flagging abnormal heart rhythm. "It's meant to be interpreting and managing a potentially life threatening situation," says Michael Matheny, co-director of the Center for Improving the Public's Health through Informatics at Vanderbilt University. As part of the FDA clearance process for the EKG, Apple had to provide and publish data showing that the feature could, in fact, flag atrial fibrillation. Doctors and experts were able to examine the information, and there are dozens of published research studies closely examining how well the watch can actually detect dangerous heart rhythms. Because the pulse oximeter is just a wellness product, though, Apple didn't have to publish any of that information. When Matheny went looking for data showing how well the Apple Watch's pulse oximeter worked compared to other devices on the market, he wasn't able to find much. "It was concerning to me," he says. Anecdotal reports from people testing the Apple Watch found that the pulse oximeter feature isn't accurate and can be hard to use. The distinction between a feature used for wellness and one used for medical monitoring is important — one has been cleared by experts, and the other hasn't. But those differences often aren't clear to people buying a product like an Apple Watch, particularly when the marketing blurs the line — as Apple did when it directly compared the heart monitoring features on the watch to the new pulse oximeter. "A lot of times, patients and consumers don't really understand the difference. So they'll start using the device and relying on the information," Matheny says. It gets more complicated when two applications that fall under different categories are in the same product, Grennan says. "It makes it confusing to think that one feature on a device is medical grade, and another feature, that looks like it's medical, is really not." The Apple Watch won't be the last product to have some features cleared by the FDA and other features categorized as wellness tools, Grennan says. "I think we're going to see a lot more of that. Pieces of technology will have multiple capabilities, and some will be vetted more than others." |
