Samsung unveils new Notebook 9 Pen 2-in-1: Bigger size, better battery


Samsung has unveiled the 2019 edition of its high-end convertible, the Notebook 9 Pen. Aimed at creative professionals, it offers a new and improved built-in S Pen that works on a device that can be used as a laptop or tablet. The 2-in-1 is available with a 13-inch or 15-inch full HD LCD screens, both of which come with a dark-blue aluminum finish, 16GB of RAM, 512GB of storage, and Intel's 8th generation Core i7 processors. The 15-inch model is a new option for the Notebook Pen. They also sport a backlit keyboard and feature facial and fingerprint recognition.

It's big, loud and secretive: We got a tour of Tesla's Gigafactory and here's how it works


Chris Lister, vice president of operations of the Tesla Gigafactory, provides insight during a tour on Dec. 3, 2018. Big numbers are one way to appreciateTesla's gargantuan Nevada Gigafactory. Operating 24-hours per day in shifts, workers produce enough battery packs and drive units in a week to power 5,300 of Tesla's Model 3 sedans. Tesla says at 5.4 million square feet, roughly equivalent to 50 Home Depot stores, the factory is just 30 percent of its potential size and is already producing more batteries than all other carmakers combined. With more than 7,000 Tesla workers, the factory is responsible for increasing manufacturing employment in the Reno-Sparks area by 55 percent since 2014, according to the Governor's Office of Economic Development.

Wi-Charge harnesses light to free Amazon Echo Dot and Google Home Mini smart speakers from power cords


A battery dock allows you to place the speaker anywhere in a room, not just in the proximity of an AC outlet. But those batteries will need recharging eventually, so most people who use them--myself included--end up leaving battery-docked smart speakers in the same places they'd be if they were AC-powered. A company called Wi-Charge claims it has a better solution: It has developed a battery-charging technology that harnesses the power of light. The power transmitter in this solution must be plugged into a wall, but the power receiver trickle-charges the battery in whatever device it's plugged into, keeping the battery forever topped off. Today, Wi-Charge announced new kits that work with Amazon Echo Dot and Google Home Mini smart speakers, so that the speakers can be placed anywhere in a room and operate without power cords.

Genetic algorithm for optimal distribution in cities Artificial Intelligence

ABSTRACT The problem to deal with in this project is the problem of routing electric vehicles, which consists of finding the best routes for this type of vehicle, so that they reach their destination, without running out of power and optimizing to the maximum transportation costs. The importance of this problem is mainly in the sector of shipments in the recent future, when obsolete energy sources are replaced with renewable sources, where each vehicle contains a number of packages that must be delivered at specific points in the city, but, being electric, they do not have an optimal battery life, so having the ideal routes traced is a vital aspect for the proper functioning of these. Now days you can see applications of this problem in the cleaning sector, specifically with the trucks responsible for collecting garbage, which aims to travel the entire city in the most efficient way, without letting excessive garbage accumulate.

How your smartphone battery could last HOURS longer

Daily Mail

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.

Dyson to build electric vehicle plant in Singapore


Dyson has announced plans to build a manufacturing plant in Singapore dedicated to producing electric vehicles, marking the first of such facilities for the UK company. Slated to complete in 2020, the two-storey advanced automotive manufacturing plant was part of Dyson's £2.5 billion (US$3.25 billion) global investment in new technology. Construction work on the Singapore site would begin in December, the company said in a statement Tuesday. Country's government has introduced initiatives to train 12,000 people in artificial intelligence skillsets, including industry professionals and secondary school students. Dyson in September 2017 said it had been working on an electric vehicle and planned to launch its first such offering in 2021.

Liquified and Chemical Hydrogen Storage in UAV Fuel Cells


Nowadays, the contemporary manufactured and small unmanned aerial vehicles (UAVs) known as drones are mostly electric-based, using electric engines for their flight power. The application of such propulsion systems need proper elaboration of efficient and light electric energy sources. The paper tends to shift our approach to drones towards one that will see efficient energy storage through the use of hydrogen – which is outlined in the following sections of this article. Speaking of, there are primarily two methods of on-board energy storing in today's drone system: The second method is one on which we are focusing in this article – mostly because of the complexity of the fuel cells and their constant need for the supply of hydrogen. Currently, hydrogen can be stored in compressed state in pressure bottles or in its liquid state (in cryogenic tanks).

The Faster, Cheaper, Better Way to Charge Electric Vehicles


Chinese carmaker NIO, the world's newest electric vehicle unicorn, has a big idea: battery swapping. In theory, the process is quicker and more convenient than a fast charge. A driver rolls into a battery swap station, and a robot replaces the drained battery with a fully charged spare. But even though NIO's battery swapping stations are already deployed in major cities across China, retail investors don't seem to be taking NIO's swap network seriously.

Huawei Mate 20 and 20 Pro unveiled: More AI, better cameras, wireless charging


Huawei has unveiled the 2018 updates to last year's 5.9-inch Mate 10 and 6.0-inch Mate 10 Pro smartphones. There are no surprises with the naming of the two new handsets, the Mate 20 and the Mate 20 Pro, which are targeted at what Huawei calls'new entrepreneurs' -- typically, the denizens of startups in tech hubs such as the venue for the company's London pre-brief last week. "That's the audience that really resonates with the Mate family," said Peter Gauden, Huawei's global senior product marketing manager, at the pre-brief: "High achievers who understand technology as a tool, and how it advances what they can do." The flagship smartphone market is as competitive as ever, with vendors typically pursuing ever more on-device AI and better camera performance, among other things. Huawei has certainly been holding its own up to now, leapfrogging over Apple to take second spot in IDC's Q2 2018 worldwide ranking, for example.

Reolink Argus Pro review: a completely wireless indoor/outdoor security camera for modest budgets


Reolink has effectively filled a void with its Argus line of affordable, no-frills, wireless indoor/outdoor security cameras. The Argus Pro is its latest offering, but it's not a premium model as you might expect given the name. In fact, it lacks a few features of the original Argus cameras--though you likely won't miss them--and, at just $100, it actually costs a bit less. Having reviewed the Argus 2, using the Argus Pro was a case of deja vu all over again. The cameras have virtually identical features: 1080p live streaming and recording, a 130-degree field of view, two-way audio, and PIR motion detection.
