    Russian Scientists Upgrade Nuclear Battery Design To Increase Power Output
    schwit1 shares a report from ScienceAlert: A team of Russian researchers have put a new spin on technology that uses the beta decay of a radioactive element to create differences in voltage. The devices are made of stacks of isotope of nickel-63 sandwiched between a pair of special semiconducting diodes called a Schottky barrier. This barrier keeps a current headed one way, a feature often used to turn alternating currents into direct ones. Finding that the optimal thickness of each layer was just 2 micrometers, the researchers were able to maximize the voltage produced by every gram of isotope. Nickel-63 has a half-life of just over 100 years, which in an optimized system like this adds up to 3,300 milliwatt-hours of energy per gram: ten times the specific energy of your typical electrochemical cell. It's a significant step up from previous nickel-63 betavoltaic devices, and while it isn't quite enough to power your smart phone, it does bring it into a realm of being useful for a wide variety of tasks.

    Programmer Creates Bee Counter Using a Raspberry Pi
    Programmer Mat Kelsey created a bee counter to see exactly how many bees are hanging out in his hives. "His system, which uses a Raspberry Pi and a machine learning algorithm that recognizes the number of individual bees entering a hive, is used to see bee trends over time and see just how the bees are faring," reports TechCrunch. From the report: The system looks at sets of pictures of the hive door taken every 10 seconds. It then extrapolates out the background, assesses the objects that have moved in the frame, and then counts the things that are likely to be bees. It's a fascinating problem to solve since the bees are constantly moving and because it can also ignore bees that are coming out of the hive. You can download the source on Github and check out his detailed blog post here. Given the need for bee protection as we enter an era of colony collapses, tools like this one are wildly important. Plus it's cool to see a Raspberry Pi do something so complex.

    Humans Are Still Crucial To Amazon's Fulfillment Process
    Amazon's fleet of automated warehouse robots, now more than 100,000 machines strong, is working alongside human employees to help meet the e-commerce giant's massive fulfillment demand. From a report: The company's robots carry inventory around massive warehouse floors, compiling all the items for a customer's order and reducing the need for human interaction with the products. But the chief technologist of Amazon Robotics, Tye Brady, insists that these robots are enhancing human efficiencies rather than eliminating warehouse jobs. Amazon has been going full steam ahead when it comes to hiring and now employs over 500,000 people. Brady views the robots as necessary to this growth. "When there are tens of thousands of orders going on simultaneously, you are getting beyond what a human can do," he told the audience at MIT Technology Review's first EmTech Next conference today. Humans still provide necessary skills in the fulfillment process, like dexterity, adaptiveness, and plain old common sense. For example, when some popcorn butter accidentally fell off a pod in a fulfillment center, it got squished, creating a big buttery mess in the middle of the floor. The curious robots didn't know how to handle the situation but wanted to go check it out. "The robots were driving through it, and they'd slip and get an encoder error," says Brady.

    Nvidia Launches AI Computer To Give Autonomous Robots Better Brains
    An anonymous reader quotes a report from The Verge: At Computex 2018, Nvidia unveiled two new products: Nvidia Isaac, a new developer platform, and the Jetson Xavier, an AI computer, both built to power autonomous robots. Nvidia CEO Jensen Huang said Isaac and Jetson Xavier were designed to capture the next stage of AI innovation as it moves from software running in the cloud to robots that navigate the real world. The Isaac platform is a set of software tools that will make it simpler for companies to develop and train robots. It includes a collection of APIs to connect to 3D cameras and sensors; a library of AI accelerators to keep algorithms running smoothly and without lag; and a new simulation environment, Isaac Sim, for training and testing bots in a virtual space. Doing so is quicker and safer than IRL testing, but it can't match the complexity of the real world. But the heart of the Isaac platform is Nvidia's new Jetson Xavier computer, an incredibly compact piece of hardware that's comprised of a number of processing components. These include a Volta Tensor Core GPU, an eight-core ARM64 CPU, two NVDLA deep learning accelerators, and processors for static images and video. In total, Jetson Xavier contains more than 9 billion transistors and delivers over 30 TOPS (trillion operations per second) of compute. And it consumes just 30 watts of power, which is half of the electricity used by the average light bulb. The cost of one Jetson Xavier (along with access to the Isaac platform) is $1,299, and Huang claims the computer provides the same processing power as a $10,000 workstation "AI, in combination with sensors and actuators, will be the brain of a new generation of autonomous machines," said Huang. "Someday, there will be billions of intelligent machines in manufacturing, home delivery, warehouse logistics and much more."

    watchOS 5 Brings Automatic Workout Detection, Walkie-Talkie Mode, Podcast App To Apple Watch
    At WWDC 2018, Apple announced several new features in watchOS 5 that will be coming to the Apple Watch later this year. Digital Trends summarizes all the big new additions including more watch faces and improved health tracking features: Apple is putting a huge emphasis on ensuring fitness tracking data is accurate in WatchOS 5. The company studied more than seven terabytes of fitness data from more than 12,000 participants to make sure its tracking measurements are on point. You'll also find a new competition mode on WatchOS 5. The mode allows you to enter a seven-day competition with a friend. WatchOS 5 also features new fitness modes. The Yoga mode will track your activity via the heart rate monitor while the Hiking mode will use your pace and elevation to better determine the number of calories burned. The Running mode now offers a custom pace alert, tracks your cadence and will even provide time data on the previous mile run. Finally, you'll see new start and end workout alerts. WatchOS 5 also brings several awesome communications improvements. First off is the new Walkie-Talkie mode. With Walkie-Talkie, you can add friends to your Apple Watch and communicate with them directly by tapping the Talk button within the Walkie-Talkie app. Your Siri watch face will also get a huge update as well. The new Siri watch face will provide more information on your favorite sports teams, offer commute and traffic information, as well as heart rate. Also available in watchOS 5 are Siri Shortcuts, an official Podcast app, and WebKit, which will let you view webpages from Messages or emails. You will also no longer need to say "Hey Siri" to activate Siri. Now you can simply raise your wrist to your mouth and Siri will automatically be listening. Note: The original Apple Watch won't get watchOS 5's new features. You will need a Series 1 or newer timepiece.
