Brain-machine interface helped a man with paralysis feed himself using robotic arms

People with arm paralysis might easily feed themselves in the future. Johns Hopkins University-led researchers have developed a new technique that let a partially paralyzed man feed himself using robotic arms connected through a brain-machine interface. He only had to make small movements with his fists at certain prompts (such as “select cut location”) to have the fork- and knife-equipped arms cut food and bring it to his mouth. He could have dessert within 90 seconds, according to the researchers.

The new method centers on a shared control system that minimizes the amount of mental input required to complete a task. He could map his four-degree freedom of movement (two for each hand) to as many as 12 degrees of freedom for controlling the robot arms. The limbs’ prompt-based intelligent responses also reduced the workload.

The technology is still young. Scientists want to add touch-like sensory feedback instead of relying exclusively on visuals. They also hope to improve the accuracy and efficiency while reducing the need for visual confirmation. In the long term, though, the team sees robotic arms like these restoring complex movements and providing more independence to people with disabilities.

House Democrats are working on legislation to protect people’s period tracker data

In a letter posted on her official website, House Speaker Nancy Pelosi has revealed that House Democrats have been working on legislation to protect personal data collected by reproductive health trackers. It’s one of the three avenues the lawmakers are exploring following the Supreme Court’s decision to overturn Roe v. Wade. “Many fear that this information could be used against women by a sinister prosecutor in a state that criminalizes abortion,” she explained, though she didn’t expound on how the lawmakers plan to protect people’s personal data. 

Users have been swapping their period trackers for others they believe can offer them more privacy ever since the Supreme Court decision dropped. It’s not unusual for companies to sell user information or to cooperate with law enforcement, and people are concerned about the possibility of investigators using that data to identify them if they ever seek an abortion. As TechCrunch reported, a number of reproductive health apps enjoyed a surge of new signups over the weekend. 

One of those apps is Flo, which announced that it plans to launch an anonymous mode shortly after the Supreme Court decision came out. The mode is supposed to remove one’s personal information from their account so that they can’t be identified, but Flo has yet to reveal when it will become available. It’s worth noting that Flo’s average daily installs has been on the decline, based on Apptopia numbers cited by TechCrunch, likely because it has a history of sharing private data with third parties.

Back in 2019, The Wall Street Journal listed Flo as one of the apps that had been giving Facebook access to people’s sensitive data. Two years later, Flo settled with the FTC over allegations that it was sharing information with the social network, Google and other third-party companies. As part of that settlement, Flo now has to explicitly ask for user consent before it can give external services access to their personal health information.

Despite the House Speaker’s announcement that House Democrats are working “to protect the health and freedom of American women,” there’s no guarantee that the legislation they’re cooking up would be signed into law. It’s always smart to take a closer look at how apps are protecting user data by reading their “nutritional label” on iOS or their “safety section” in the Play Store on Android. But for those who want to be truly safe, perhaps the best solution is to not use a period tracking app at all.

Hummer EV’s obstacle-avoiding Extract Mode adds six inches of ride height

GMC Hummer EV owners will soon be able to raise their 9,000-pound vehicle nearly six additional inches in the air, all due to a simple software update. Over the new few weeks, GMC will be adding a new “Extract Mode” — which lets drivers elevate their v…

The Supreme Court won’t hear the Apple-Qualcomm patent case

Apple and Qualcomm may have ended most of their feuding in 2019, but the fight might not be over just yet. The Vergereports that the Supreme Court has denied Apple’s request for a hearing to potentially invalidate two Qualcomm patents that played key roles in 2017 attempts to ban Apple Watch, iPad and iPhone sales over allegedly infringing modem technology. The court didn’t explain why it rejected the request, but a Justice Department amicusbrief from May argued that there was no evidence to indicate the patents were harming Apple’s business.

While the companies struck a six-year licensing deal to settle their main dispute, the agreement let a US Patent and Trademark Office case continue involving the two patents. Apple lost an attempt to invalidate the patents with the USPTO’s Patent Trial and Appeal Board, and again failed when a Federal Circuit court tossed out Apple’s appeal request based on the settlement. When Apple went to the Supreme Court, the Justice Department filed its supporting brief opposing the request.

Apple claimed in its request that Qualcomm might use the patents to sue again once the licensing deal expires in 2025 or (if extended) 2027. It’s not certain what either company will do next. We’ve asked both Apple and Qualcomm for comment. The landscape may change significantly within the next few years, however. Apple is rumored to be ditching Qualcomm in favor of using its own 5G modems as soon as 2023, and it’s not yet clear how that might affect the current truce.
