Despite being photographed outdoors in full sunlight, a 160-mm-diagonal, color cholesteric liquid-crystal display, built with off-the-shelf electronics for demonstration purposes by Kent Displays Inc., shows a bright image. The image is produced by reflected light, not backlighting, and no power is needed to hold the image on the screen.

It would be a lot easier to read a laptop display if the information on it looked as if it were printed on paper, as in a newspaper or magazine. The backlit screen would not wash out in bright light, but would look even brighter. One could view the screen from any angle and still be able to read it. Text and images would be sharp and details would be clear. And what if, as a bonus, the display consumed no power while it was being read?

Sounds good, doesn't it? Well, a trio of displays being developed will do all that. The goal is for them to look and work like paper. They reflect ambient light and retain images indefinitely, rather than rely on back-lighting and screen refreshing as a laptop's display does, so they need not consume power to be readable. And they can be read from any angle, because they reflect light evenly in all directions, a property referred to as Lambertian reflection.

New AI Speeds Computer Graphics by Up to 5x

Neural rendering harnesses machine learning to paint pixels

Four examples of Nvidia's Instant NeRF 2D-to-3D machine learning model placed side-by-side.

Nvidia Instant NeRF uses neural rendering to generate 3D visuals from 2D images.

On 20 September, Nvidia’s Vice President of Applied Deep Learning, Bryan Cantanzaro, went to Twitter with a bold claim: In certain GPU-heavy games, like the classic first-person platformer Portal, seven out of eight pixels on the screen are generated by a new machine-learning algorithm. That’s enough, he said, to accelerate rendering by up to 5x.

This impressive feat is currently limited to a few dozen 3D games, but it’s a hint at the gains neural rendering will soon deliver. The technique will unlock new potential in everyday consumer electronics.

Golf Robot Learns To Putt Like A Pro

Watch out Tiger Woods, Golfi has a mean short game

Golf Robot Learns To Putt Like A Pro

While being able to drive the ball 300 yards might get the fans excited, a solid putting game is often what separates a golf champion from the journeymen. A robot built by German researchers is quickly becoming a master of this short game using a clever combination of classical control engineering and machine learning.

In golf tournaments, players often scout out the greens the day beforehand to think through how they are going to play their shots, says Annika Junker, a doctoral student at Paderborn University in Germany. So she and her colleagues decided to see if giving a robot similar capabilities could help it to sink a putt from anywhere on the green, without assistance from a human.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
