Google: Our new Android P beta shows how AI gives you more battery life


Android P: Google launches first developer preview. Google's Android developers have teamed up with Alphabet's DeepMind researchers to bring deep neural-net enhancements to Android P. The enhancements, which target battery life and screen performance, have been unveiled alongside the launch of the first Android P beta, which is now open to six more handset models beyond Google's Pixel devices. The beta follows the first Android P developer preview in March. Owners with a Sony Xperia XZ2, Xiaomi Mi Mix 2S, Nokia 7 Plus, Oppo R15 Pro, Vivo X21UD and X21, and Essential PH‑1 can now join the Android P beta program. This beta program will be the fastest route to testing Android P's new Adaptive Battery feature, which was developed with researchers from the unit at Google parent Alphabet's AI firm, DeepMind, dedicated to delivering AI breakthroughs just for Google.

Android P taps AI to help save your battery life


Today at the Google I/O keynote, the search giant took the opportunity to showcase all the new ways artificial intelligence will revolutionize its phone OS with the upcoming Android P. One of the least sexy AI applications might benefit the most users. Adaptive Battery, as its called, takes note of user behavior to cunningly switch off apps when it predicts you'll need them least -- and will result in a 30 percent reduction in CPU app wakeups, which should save you some juice. In other words, if it knows you only click through Instagram during your morning and afternoon coffee breaks, it'll close it in the interim -- and save you some battery life. Similarly, Android P has a feature called Adaptive Brightness that dims the screen when it predicts you won't need it lit up so much. Click here to catch up on the latest news from Google I/O 2018!

Safe Battery System For the UAV Industry – DEEP AERO DRONES – Medium


Many people discussed on the innovative ideas to extend time in the air (TITA), ranging from traditional tethered solutions to really innovative, small rotary engines. Since this topic arouse, the performance of the Lithium-ion battery have been improved and on the other hand, TITAs are also supposed to get longer. With the innovations in the UAVs, the battery suppliers are also accelerating their growth. UL created a new standard to help ensure the safety of Li-ion batteries used in UAVs. Alternatives such as hydrogen fuel cells would also work well, but these new and innovative solutions had a bright future.

Liberate your Amazon Echo 2 from the constraints of a power cord


Ninety7 specializes in battery docks that render smart speakers portable, so it's appropriate that the company's new product for the Amazon Echo 2 features a large, easy-to-grab handle. The Sky is a replacement sleeve for the Echo 2 that docks the speaker to an 8800mAh Li-ion battery, so you can take Alexa out in the yard or on even on the road. The company says the battery should power an Echo 2 for about 8 hours, and a column of four LEDs near the bottom of the sleeve report the battery life remaining. I'm sure that will vary depending on how many times you summon Alexa and how much you use the Echo 2 to stream music. The battery gets recharged from the Echo 2's factory AC adapter and cable.

Self-heating-induced healing of lithium dendrites


Lithium (Li) metal electrodes are not deployable in rechargeable batteries because electrochemical plating and stripping invariably leads to growth of dendrites that reduce coulombic efficiency and eventually short the battery. It is generally accepted that the dendrite problem is exacerbated at high current densities. Here, we report a regime for dendrite evolution in which the reverse is true. In our experiments, we found that when the plating and stripping current density is raised above 9 milliamperes per square centimeter, there is substantial self-heating of the dendrites, which triggers extensive surface migration of Li. We show that repeated doses of high-current-density healing treatment enables the safe cycling of Li-sulfur batteries with high coulombic efficiency.

Robots Are Fueling the Quiet Ascendance of the Electric Motor


If you were going to kick off a technological revolution, you'd be hard-pressed to do it with more pizazz than Tesla with its electric cars. But oddly enough, what's driving it all--the electric motor--is an ancient technology at this point. It's lost out to the gas engine for over a century, sure, but it's finally begun to take over transportation, thanks to supporting roles from better batteries and fancy sensors.

Eight reasons the Huawei Mate 10 Pro is good for business


The massive 4,000 mAh battery of the Mate 10 Pro is a welcome addition and ensures you can go a couple of days with heavy usage on this phone. RAM and storage: The new Huawei Mate 10 Pro has 6GB of RAM with 128 GB of integrated storage. Both are ample for today's daily usage. Easy projection: Samsung DeX is great, but it requires a DeX dock. Huawei lets you simply connect an external display via the USB Type C port to project the device onto an external display.

Battery safety and fire handling


Lithium battery safety is an important issue as there are more and more reports of fires and explosions. Fires have been reported in everything from cell phones to airplanes to robots.

GE Working on Robot That It Says Can Save $200 Billion of Power


General Electric Co. is working on a way to use artificial intelligence in electricity grids, a technology that it expects will save $200 billion globally by improving efficiency. "We're also putting a lot into the machine learning side, a lot," said Steven Martin, chief digital officer at GE's energy connections business, at an interview at the Bloomberg New Energy Finance summit in London. "We have a lot of people working on this." This is expected to significantly increase the efficiency of the grid and save consumers money. Researchers are looking into how so-called machine learning can be integrated into businesses from healthcare to computing, and now energy.

Inception Drive: A Compact, Infinitely Variable Transmission for Robotics

IEEE Spectrum Robotics Channel

Last year, SRI's Alexander Kernbaum introduced us to Abacus Drive, a new kind of rotary transmission based on pure rolling motion that promises to be much cheaper and much more energy efficient than harmonic gears, which are the current (quite expensive) standard. Now Kernbaum is back with another ingenious--and cleverly named--transmission design. It's called Inception Drive, and he describes it as "an ultra-compact infinitely variable transmission based on a novel nested pulley configuration" that's designed to make robots, and all kinds of other things, safer, more affordable, and vastly more efficient. In an infinitely variable transmission (IVT), which is a specific kind of continuously variable transmission, the transmission ratio includes a zero point that can be approached from either a positive side or a negative side. In other words, a constant input, like an electric motor turning the same direction at the same speed, can be converted to an output that's turning faster, turning slower, turning the opposite direction, or not turning at all (in this "geared neutral" mode, you'd need infinite input revolutions to cause one output revolution, hence the name infinitely variable transmission).
