Forward-looking: Future electronics still have room to get a lot smaller. New techniques for creating optical gyroscopes may make motion and orientation detection significantly better all while chips take up significantly less space. Accelerometers and gyroscopes are often paired together for motion tracking and orientation detection within cell phones, tablets, game controllers, vehicles, and dozens of other common everyday devices. Building super small devices that are both precise and accurate is already difficult enough, but achieving the best possible accuracy today requires a device roughly the size of a golf ball. Researchers from Caltech have developed an optical gyroscope that is no larger than a grain of rice and has higher accuracy than the more common MEMS gyroscopes most people have in their electronics. Instead of using identical oscillating masses that move, optical gyroscopes rely on the Sagnac Effect. Going back to Einstein's theory of general relativity, French … [Read more...] about New optical gyroscope is more accurate and as small as a grain of rice

The article was posted online by Nature Photonics on October 19 and can be found here: https://www.nature.com/articles/s41566-018-0266-5 Gyroscopes are devices that help vehicles, drones, and wearable and handheld electronic devices know their orientation in three-dimensional space. They are commonplace in just about every bit of technology we rely on every day. Originally, gyroscopes were sets of nested wheels, each spinning on a different axis. But open up a cell phone today, and you will find a microelectromechanical sensor (MEMS), the modern-day equivalent, which measures changes in the forces acting on two identical masses that are oscillating and moving in opposite directions. These MEMS gyroscopes are limited in their sensitivity, so optical gyroscopes have been developed to perform the same function but with no moving parts and a greater degree of accuracy using a phenomenon called the Sagnac effect. What is the Sagnac Effect? The Sagnac effect, named after French physicist … [Read more...] about Spinning the Light: The World’s Smallest Optical Gyroscope
Article Contents1 Fitbit Ionic2 Fitbit Flyer3 Fitbit Aria 23.1 Press Release3.2 Press Release Back in December of last year, Fitbit paid $40 million for Pebble. Considering Pebble's entire future product lineup was cancelled as a result of the buyout, many hoped that Fitbit would at least offer a similar product in the future. The company's new smartwatch is finally here - the Ionic - as well as two other new fitness products. Fitbit Ionic Let's start with the Ionic. It has a color LCD touchscreen, but can supposedly still last around four days on a single charge (when you're not using GPS). As for the rest of the hardware, it has Bluetooth 4.0 Low-Energy, Wi-Fi connectivity (802.11 b/g/n), a heart rate sensor, an ambient light sensor, and even NFC. Moving onto the software features, the Ionic can create personalized workouts based on your recent activity, display a map of your current run/bike/hike with elevation and distance data, store music, play said music through Bluetooth … [Read more...] about Fitbit announces its first smartwatch, the Ionic, along with new wireless earbuds and a smart scale

Gooding & Company, the official auction house of the Pebble Beach Concours d’Elegance, is presenting a particularly impressive fleet of automobiles on Friday, August 24 and Saturday, August 25. Some of the cars in Gooding & Company’s fleet include a 1935 Duesenberg SSJ, a 1949 Alfa Romeo 6C 2500, and a 1956 Mercedes Benz 300 SL Gullwing. The 2018 Pebble Beach Concours d’Elegance kicked off this week in California with antique car enthusiasts and collectors the world over flocking to place bids and see some of the most expensive vehicles on Earth. Since it began in 1950, the Pebble Beach Concours has been the top-ranked car collector competition in the world. It has evolved over time, from its initial focus on … [Read more...] about These 18 beautiful, vintage cars are worth millions and are up for auction at Pebble Beach
This August, some of the world’s best professional gamers will travel to Vancouver to fight for millions of dollars in the world’s most valuable esports competition. They’ll be joined by a team of five artificial intelligence bots backed by Elon Musk, trying to set a new marker for the power of machine learning. The bots were developed by OpenAI, an independent research institute the Tesla CEO cofounded in 2015 to advance AI and prevent the technology from turning dangerous. Vancouver is hosting the annual world championship of Dota 2, one of the internet’s most-watched videogames. The prize purse is more than $15 million and growing, exceeding the $11 million at stake at golf’s Masters. In each game, two teams of five people attempt to destroy each others’ bases, playing characters that can include demons, spiders, and icy ghosts. Earlier this month, OpenAI’s team, OpenAI Five, played and beat a team of semipros among the top 1 percent on the … [Read more...] about Can Bots Outwit Humans in One of the Biggest Esports Games?
