A deep learning-augmented smart mirror to enhance fitness training

Posted by in categories: health, information science, mobile phones, robotics/AI

In recent years, engineers and computer scientists have created a wide range of technological tools that can enhance fitness training experiences, including smart watches, fitness trackers, sweat-resistant earphones or headphones, smart home gym equipment and smartphone applications. New state-of-the-art computational models, particularly deep learning algorithms, have the potential to improve these tools further, so that they can better meet the needs of individual users.

Researchers at University of Brescia in Italy have recently developed a computer vision system for a smart mirror that could improve the effectiveness of fitness training both in home and gym environments. This system, introduced in a paper published by the International Society of Biomechanics in Sports, is based on a deep learning algorithm trained to recognize human gestures in video recordings.

This Mighty Brain Chip Is So Efficient It Could Bring Advanced AI to Your Phone

Posted by in categories: information science, mobile phones, robotics/AI

Or so goes the theory. Most CIM chips running AI algorithms have solely focused on chip design, showcasing their capabilities using simulations of the chip rather than running tasks on full-fledged hardware. The chips also struggle to adjust to multiple different AI tasks—image recognition, voice perception—limiting their integration into smartphones or other everyday devices.

This month, a study in Nature upgraded CIM from the ground up. Rather than focusing solely on the chip’s design, the international team—led by neuromorphic hardware experts Dr. H.S. Philip Wong at Stanford and Dr. Gert Cauwenberghs at UC San Diego—optimized the entire setup, from technology to architecture to algorithms that calibrate the hardware.

The resulting NeuRRAM chip is a powerful neuromorphic computing behemoth with 48 parallel cores and 3 million memory cells. Extremely versatile, the chip tackled multiple AI standard tasks—such as reading hand-written numbers, identifying cars and other objects in images, and decoding voice recordings—with over 84 percent accuracy.

SpaceX rocket launches the largest commercial satellite into orbit. It could also blind our view of the universe

Posted by in categories: mobile phones, satellites

The BlueWalker 3 prototype satellite is extremely bright and could interfere with celestial data.

The brightest star in the sky may not be a star for much longer. It could be a colossal internet satellite featuring a giant antenna array covering an area of 689 square feet (64 square meters) for regular cellphones to access the internet from space.

Watch SpaceX launch the huge BlueWalker 3 satellite, Starlink fleet on rocket’s record-setting 14th flight tonight

Posted by in categories: mobile phones, satellites

A SpaceX Falcon 9 rocket will fly for a record-breaking 14th time on Saturday night (Sept. 10), launching 34 of the company’s Starlink internet satellites and a huge direct-to-smartphone connectivity test spacecraft to orbit, and you can watch it live.

The two-stage Falcon 9, topped with the Starlinks and AST SpaceMobile’s Blue Walker 3 test satellite, is scheduled to lift off from NASA’s Kennedy Space Center (KSC) in Florida Saturday at 9:10 p.m. EDT (0110 GMT on Sept. 11). Watch it live here at Space.com, courtesy of SpaceX, or directly via the company (opens in new tab).

Modified microwave oven cooks up next-gen semiconductors

Posted by in categories: computing, mobile phones

A household microwave oven modified by a Cornell engineering professor is helping to cook up the next generation of cellphones, computers and other electronics after the invention was shown to overcome a major challenge faced by the semiconductor industry.

The research is detailed in a paper published in Applied Physics Letters. The lead author is James Hwang, a research professor in the department of materials science and engineering.

As microchips continue to shrink, silicon must be doped, or mixed, with higher concentrations of phosphorus to produce the desired current. Semiconductor manufacturers are now approaching a critical limit in which heating the highly doped materials using traditional methods no longer produces consistently functional semiconductors.

Elon Musk reveals SpaceX and Apple discussed Starlink support for iPhone 14

Posted by in categories: Elon Musk, mobile phones, satellites

Apple could become the first commercially available smartphone with a satellite in the U.S.

Just a day after Apple announced the iPhone 14’s emergency SOS via satellite feature, SpaceX chief executive officer Elon Musk revealed that SpaceX had talked with Apple Inc about using Starlink connectivity.

Elon’s Real World AI is the Real World Technological Singularity

Posted by in categories: economics, Elon Musk, employment, mobile phones, Ray Kurzweil, robotics/AI, singularity, sustainability, transportation

Ray Kurzweil predicted Technological Singularity nearly 20 years ago. Elon Musk could enable a world of economic abundance with real world AI. Robotaxi and Teslabot will transform the world more than car and the first industrial revolution.

Tesla sells Model Ys for about $60000, but it currently costs them about $30000–40000 to make them. A Teslabot is 1/30th of the mass of a Model Y. It will use 1/30th of the batteries. The software is an overall cost of development. If billions of bots are produced then the cost would trend toward the cost of the hardware plus Apple iPhone-like margins including the software (say 40% gross margin). At Model Y cost of $30k then the hardware cost for Teslabot will go to $1000. $2000 with margins and software. A bot can work for 8,000 hours in a year. 8,760 hours in a year. $2000 divided by 8,000 hours is $0.25. If you add 10 cents per hour for electricity then it is $0.35 per hour. Going beyond that is bots can work in the factory and work cheaper than humans. Currently 15,000 workers in Tesla China factory. Replace all of them with $0.35 per hour bots. Reduce labor cost component. If a lot of bots can increase production rates. by 2X then all costs spread over more units. Bot-produced solar and batteries can lower the cost of energy by vastly increasing the supply. Those trends could get us to $500‑1000 per bot costs and lower energy costs. Having virtually unlimited labor costing less than 35 cents per hour will be transformational.

The iPhone 14 ditches physical SIM cards for eSIM

Posted by in category: mobile phones

Apple’s new iPhones — the iPhone 14 and iPhone 14 Plus — won’t have physical SIM cards. The company announced the nugget at its event in Cupertino today, revealing that eSIM will be the only way the iPhone 14 series authenticates with wireless carriers — at least in the U.S.

ESIM lets you change a wireless carrier, data or service plan through software rather than having to swap a physical SIM card. It’s hardly a new technology, but it’s only within the last few years that eSIM has become more common on mainstream mobile devices.

Apple said that major carriers including T-Mobile, Verizon and AT&T will provide resources to assist with eSIM-related questions, service upgrades and changes.

The iPhone 14 can connect to satellites for emergency SOS features

Posted by in categories: mobile phones, satellites

Probably the biggest new feature for the iPhone 14, 14 Plus and 14 Pro isn’t one you’ll use ever day, but you’ll be glad you have it if you need it. The new phones have a built-in satellite connection that people can use to send emergency SOS messages in places where there’s no available cellular signal.

First, your iPhone will help you orient your phone in the direction you need to point it to get the best signal. Once you have a connection, you can open up a message interface that lets you communicate with emergency service providers. Apple says that because of satellite connectivity limits, it’ll take much longer to send messages than you’re used to, so the feature includes some automatic questions it prompts you to answer, like “is anyone hurt?” It’ll have auto-populated answers that you can tap to respond. Apple is also compressing messages to a third of their normal size to make sending them a little quicker.

Apple say that once the message is sent to the satellite, it then gets routed to emergency response centers; if those centers are only set up for voice calls, they’ll first be passed to a response center that’ll then get in touch with emergency response.
