Researchers Just Wirelessly Transmitted Power Over 98 Feet of Thin Air
We could one day charge our phones and tablets wirelessly through the air, thanks to newly developed technology.
Researchers have used infrared laser light to transmit 400mW of light power over distances of up to 30 meters (98 feet). That’s enough juice to charge small sensors, though in time it could be developed to charge up larger devices such as smartphones too.
All this is done in a way which is perfectly safe – the laser falls back to a low power mode when not in use.
No VR or AR: A new pocket-size eyeglass will be just big screen experience in your eyes
You need to wait till 2023 to get them though.
Lenovo has unveiled its T1 Glasses at its Tech Life 2022 event and promises to place a full HD video-watching experience right inside your pockets, a company press release.
Mobile computing devices have exploded in the past few years as gaming has become more intense, and various video streaming platforms have gathered steam. The computing power of smartphones and tablets has increased manifold. Whether you want to ambush other people in an online shooting game or sit back and watch a documentary in high-definition, a device in your pocket can help you do that with ease.
However, what is missing is the large screen experience; with the T1 Glasses, Lenovo wants to deliver just that.
Addiction, crime and data breaches: The metaverse could become a wild west if we’re not careful
But with such a rapid expansion into this new virtual world, will it be safe, regulated and, is it something we should fear or accept with open arms?
We talk to David Reid, a Professor of AI and spatial computing at Liverpool Hope University to see what to expect from the future of the metaverse.
There’s a few definitions. You can think of it from a technological viewpoint, where it’s simply the successor of the internet. Computers once took up big rooms, but they’ve shrunk until we got things like pocket-sized smartphones that you constantly interact with. The metaverse takes this a step further, making the actual environment you interact with virtual, removing the interface of computers completely.
Why ‘erasure’ could be key to practical quantum computing
Researchers have discovered a new method for correcting errors in the calculations of quantum computers, potentially clearing a major obstacle to a powerful new realm of computing.
In conventional computers, fixing errors is a well-developed field. Every cellphone requires checks and fixes to send and receive data over messy airwaves. Quantum computers offer enormous potential to solve certain complex problems that are impossible for conventional computers, but this power depends on harnessing extremely fleeting behaviors of subatomic particles. These computing behaviors are so ephemeral that even looking in on them to check for errors can cause the whole system to collapse.
In a paper outlining a new theory for error correction, published Aug. 9 in Nature Communications, an interdisciplinary team led by Jeff Thompson, an associate professor of electrical and computer engineering at Princeton, and collaborators Yue Wu and Shruti Puri at Yale University and Shimon Kolkowitz at the University of Wisconsin-Madison, showed that they could dramatically improve a quantum computer’s tolerance for faults, and reduce the amount of redundant information needed to isolate and fix errors. The new technique increases the acceptable error rate four-fold, from 1% to 4%, which is practical for quantum computers currently in development.
Will AR Smart Glasses Replace Smartphones and Become our Personal Buddy Bots?
By Thomas Frey | Sep 1, 2022 | Artificial Intelligence
When Steve Jobs unveiled the iPhone in 2007, no one understood at the time how disruptive that device would be to existing technology. Now with rumors of Apple launching their augmented reality (AR) smart glasses products next year, people are speculating about how disruptive this technology will be.
Since iPhones are one of Apple’s primary revenue streams, they may be cautious about releasing a product that may encroach on their own turf. However, as we’ll suggest below, it may not be an either/or situation for users.
Researchers use infrared light to wirelessly transmit power over 30 meters
We might be too close to wirelessly charging our mobile devices anywhere.
Researchers from Sejong University have developed a new system to transmit power over 30 meters using infrared light wirelessly. During laboratory tests, researchers demonstrated that the new system could transfer 400 mW of light power. For now, this amount of power is enough for charging sensors; however, further progress could mean enough high levels to charge mobile phones in various public places.
The research has been published in Optics Express.
In Optics Express, researchers describe a new wireless laser charging system that overcomes some of the challenges that have hindered previous attempts to develop safe and convenient on-the-go charging systems.
Excessive blue light from our gadgets may accelerate the aging process
Too much screen use has been linked to obesity and psychological problems. Now a new study has identified a new problem—a study in fruit flies suggests our basic cellular functions could be impacted by the blue light emitted by these devices. These results are published in Frontiers in Aging.
“Excessive exposure to blue light from everyday devices, such as TVs, laptops, and phones, may have detrimental effects on a wide range of cells in our body, from skin and fat cells, to sensory neurons,” said Dr. Jadwiga Giebultowicz, a professor at the Department of Integrative Biology at Oregon State University and senior author of this study. “We are the first to show that the levels of specific metabolites—chemicals that are essential for cells to function correctly—are altered in fruit flies exposed to blue light.”
“Our study suggests that avoidance of excessive blue light exposure may be a good anti-aging strategy,” advised Giebultowicz.
FTC Sues Data Broker Over Selling Location Data for Hundreds of Millions of Phones
The U.S. Federal Trade Commission (FTC) on Monday said it filed a lawsuit against Kochava, a location data broker, for collecting and selling precise geolocation data gathered from consumers’ mobile devices.
The complaint alleges that the U.S. company amasses a “wealth of information” about users by purchasing data from other data brokers to sell to its own clients.
“Kochava then sells customized data feeds to its clients to, among other purposes, assist in advertising and analyzing foot traffic at stores or other locations,” the FTC said. “Among other categories, Kochava sells timestamped latitude and longitude coordinates showing the location of mobile devices.”
