Magnesium Key for Bigger, Safer Batteries?

PDF Print E-mail

Berkeley Lab researchers announce a "major step" towards energy dense and safe solid-state magnesium-ion rechargeable batteries through the discovery of the fastest magnesium-ion solid-state conductor yet.

magnesium battery researchMagnesium promises higher energy density than the currently used lithium. However it lacks good options for liquid electrolyte, with most being actually corrosive against other parts of the battery. As a result, the researchers bypassed the liquid option in favour of creating a solid-state alternative, the impressively named magnesium scandium selenide spinel.

Ericsson: 5G Subscriptions Reach 1bn in 2023

PDF Print E-mail

According to the Ericsson Mobility Report 5G subscriptions will reach 1 billion by 2023, with 5G covering over 20% of the world population just 4 years after the first commercial 5G New Radio (NR) networks go live in 2019.

5g mobileA number of perhaps predictable markets will get the first 5G deployments-- namely the US, S. Korea, Japan and China-- all based in dense urban areas. The forecast period also involves an 8X surge in mobile data traffic, reaching 110 Exabytes per month (or 5.5 million years of HD video streaming) per month.

The mention of streaming is relevant, since video is a main driver of mobile broadband traffic. Young millennials (in the 15-24 age bracket) stream 2.5X more than people over 45 years of age, and higher resolution and immersive 360-degree video will further impact data traffic consumption volumes.

Faster Photo Transfers With CamFi Pro

PDF Print E-mail

CamFi promises faster wireless photo transfers between cameras and PCs with the Pro-- a camera controller using 802.11ac wifi to push photos 2-3x faster than the wifi found built-in most camera bodies.

CamFi ProAccording to the company, most wifi-enabled cameras use 802.11n, meaning photo transfers can take as long as 30 seconds. The Pro doubles the speed through a connection reaching up to 10MB/s, an improvement over the 2MB/s of many built-in connection systems. This allows users to transfer larger RAW files to other devices, as well as the sending of a JPEG of a file to a device for an almost instant view of a shot.

Google Adds Vision to Raspberry Pi

PDF Print E-mail

Google provides means for customers to add its AI-powered vision to the Raspberry Pi-- the AIY Vision Kit, a package consisting of a circuit board, computer vision software and additional accessories.

AIY Vision kitThe AIY Vision Kit allows one to turn the Raspberry Pi into a more hackable version of Google's own Clips smart camera. The main component is the Vision Bonnet, a circuit board packing a Movidus MA2450 vision processing chip acting as a "neural network accelerator." It does not need to connect to the Google Cloud, meaning all images are processed locally on the device.

On the software side the kit offers 3 neural network models-- one able to recognise 1001 common objects, one able to recognise faces and expressions, and a "person, cat and dog detector." Google hopes bolder users will further improve on the neural models, for instance by adding the ability to recognise rabbits for a project used in a rabbit hutch.
