We study the online problem of minimizing power consumption in systems with multiple power-saving states. During idle periods of unknown lengths, an algorithm has to choose between power-saving states of different energy consumption and wake-up costs. We develop a learning-augmented online algorithm that makes decisions based on (potentially inaccurate) predicted lengths of the idle periods. The algorithm's performance is near-optimal when predictions are accurate and degrades gracefully with increasing prediction error, with a worst-case guarantee almost identical to the optimal classical online algorithm for the problem. A key ingredient in our approach is a new algorithm for the online ski rental problem in the learning augmented setting with tight dependence on the prediction error. We support our theoretical findings with experiments.

On a cloudy Christmas morning last year, a rocket carrying the most powerful space telescope ever built blasted off from a launchpad in French Guiana. After reaching its destination in space about a month later, the James Webb Space Telescope (JWST) began sending back sparkling presents to humanity--jaw-dropping images that are revealing our universe in stunning new ways. Every year since 1988, Popular Science has highlighted the innovations that make living on Earth even a tiny bit better. And this year--our 35th--has been remarkable, thanks to the successful deployment of the JWST, which earned our highest honor as the Innovation of the Year. But it's just one item out of the 100 stellar technological accomplishments our editors have selected to recognize. The list below represents months of research, testing, discussion, and debate. It celebrates exciting inventions that are improving our lives in ways both big and small. These technologies and discoveries are teaching us about the ...

The TriRhenaTech alliance presents the accepted papers of the 'Upper-Rhine Artificial Intelligence Symposium' held on October 27th 2021 in Kaiserslautern, Germany. Topics of the conference are applications of Artificial Intellgence in life sciences, intelligent systems, industry 4.0, mobility and others. The TriRhenaTech alliance is a network of universities in the Upper-Rhine Trinational Metropolitan Region comprising of the German universities of applied sciences in Furtwangen, Kaiserslautern, Karlsruhe, Offenburg and Trier, the Baden-Wuerttemberg Cooperative State University Loerrach, the French university network Alsace Tech (comprised of 14 'grandes \'ecoles' in the fields of engineering, architecture and management) and the University of Applied Sciences and Arts Northwestern Switzerland. The alliance's common goal is to reinforce the transfer of knowledge, research, and technology, as well as the cross-border mobility of students.

A group of researchers from Stanford have developed a way to combine processors and memory on multiple hybrid chips to allow AI to run on battery-powered devices such as smartphones and tablets. The team believes that all manner of battery-power electronics would be smarter if they could run AI algorithms. The problem is efforts to build AI-capable chips for mobile devices have run up against something known as the "memory wall." The memory wall is the name for the separation of data processing and memory chips that have to work together to meet the computational demands of AI. Computer scientist Subhasish Mitra says the transactions between processors and memory can consume 95 percent of the energy needed to perform machine learning and AI, severely limiting battery life.

Oral-B has launched its Genius X toothbrush which uses artificial intelligence to help you brush your teeth better for US$220. The Oral-B 10000 Genius X is available from their website for US$220 is the follow up to the Genius 9000, which sold from the Shavershop for AU$349. Unfortunately, there is no word on whether the Oral-B Genius X will make its way down under for Christmas. Featuring wireless Bluetooth connection, the Oral-B Genius X links to a dedicated companion app on your phone to time how long you brush your teeth for, how to pressure your applying, where you have been brushing and where you should brush more next time. Utilising sensors within the toothbrush, the device can detect pressure and its location within your mouth, something a reviewer from Forbes was most impressed about.

When I reviewed First Alert's Onelink Safe & Sound smoke alarm in mid-2018, I found it to be a powerful entry in the smart smoke detector market. Its inclusion of Bluetooth and an Amazon Echo-compatible smart speaker set it apart from every smoke and carbon-monoxide detector on the market. But its $199 price tag also made it far and away the most expensive device of its type on the market--and that price hasn't budged since its release. Enter the Onelink Smoke Carbon Monoxide Alarm, which lowers the cost of the original product by stripping out its most compelling features: The smart speaker and Bluetooth. Like other products in this category, the Onelink Smoke Carbon Monoxide Alarm is designed to extend the capabilities of a smoke detector by linking it with your smartphone.

Scientists have found a way to boost the battery life of your smartphone or tablet by several hours. They claim that shifting reams of data from your favourite apps to cloud storage services could cut the power they burn through by up to 60 per cent. Tools would identify the most power-hungry parts of a mobile app and then move them to the cloud using a technique called code-offloading. For an average smartphone with an average battery capacity, applying the technology to every app could extend the battery life by up to six hours in a'best-case scenario', researchers said. The technology could be used to build the next generation of disaster relief or search and rescue robots, where battery life is critical.

Artificial intelligence can help developers design mobile phone apps that drain less battery, according to new research. The system, dubbed DiffProff, will be presented this week at the USENIX Symposium on Operating Systems Design and Implementation conference in California, was developed by Charlie Hu and Abhilash Jindal, who have a startup devoted to better battery testing via software. DiffProf rests on the assumption that apps that carry out the same function perform similar tasks in slightly different ways. For example, messaging apps like Whatsapp, Google Hangouts, or Skype, keep old conversations and bring up a keyboard so replies can be typed and sent. Despite this, Whatsapp is about three times more energy efficient than Skype.

Taking a look back at another week of news from Cupertino, this week's Apple Loop includes the new iPhone designs for 2018, production starting on the A12 chips, Apple issuing credit notes for battery replacements, a big decision over the MacBook Air, thoughts on WWDC's announcements, Razer's macOS graphics enclosure, Apple working with VW, and an important date for macOS. Apple Loop is here to remind you of a few of the very many discussions that have happened around Apple over the last seven days (and you can read my weekly digest of Android news here on Forbes). Apple is expected to announce three new iPhone handsets in September, and the one that is catching the most attention right now is the'replacement' for the iPhone SE - all the features of the iPhone X but in a much smaller form factor. Gordon Kelly reports on the latest leaks around the design of the super small smartphone: So what do we learn? That Olixar is convinced Apple will fulfill the dreams of millions of iPhone fans, by releasing a new iPhone X variant which crams a bezel-less front display and Face ID technology into a chassis the same size as the iPhone SE. Backing this up, Mobile Fun has passed me new CAD designs showing the new iPhone's dimensions as 121.04 x 55.82 mm (4.8 x 2.2-inches) - fractionally smaller than the 123.8 x 58.6 mm (4.87 x 2.31-inches) of the iPhone SE.
