Fraunhofer Brings High-Def to Minicams

With the deployment of high-definition video sweeping the the entertainment, sports, and journalism business, Germany’s Fraunhofer Institute wanted to tackle a difficult problem: how do we get high-definition video from the perspective of, say, a sports car driver, jet pilot, or ski jumper?

To that end, the folks at Fraunhofer have developed a MicroHDTV high-definition capable mini camera, measuring just 4 by 4 by 8 centimeters and capable of capturing 1,920 by 1,080-pixel video at 60 frames per second – that’s not only a high enough resolution to accommodate 1080p resolution, but fast enough to get some slow motion footage out of crucial plays…or agonizing crashes.

“The MicroHDTV model is one of the smallest HDTV cameras currently available,” says Stephan Gick, group leader at the IIS, in a release. “We achieved this chiefly by taking two different approaches: the camera’s electronics have a very low power loss, which means that little heat is generated and the housing can thus be kept very small. By using highly integrated parts, we were able to fit all of the components such as the image sensor, the analog-to-digital converter, the color processor and several interfaces into the tiny space available inside the camera.”

The camera’s color settings, white balance, and frame rate can all be configured via software, and the entire camera can also be controlled via the Internet or standard optical systems. “Because the camera is so small and can be controlled via the Internet, it can deliver pictures of scenes that could not be viewed in the same way before—for example, recordings of sports events or applications that require the camera to be installed in difficult-to-reach places,” said Gick.

Fraunhofer developed the camera for Integrated Circuits IIS in Erlangen, and expects the camera will soon be in products from a variety of licensees.

Tesla reaches settlement with Walmart to bring solar panel suit to an end

Walmart announced that it had dropped its lawsuit against Tesla over malfunctioning solar panels manufactured by the company that resulted in fires.

The lawsuit that was filed in August was “voluntarily discontinued without prejudice” on Monday, November 4, according to court documents. A Walmart spokesperson said that a settlement has been reached and stipulation of dismissal has been filed with the court.

Moment Air brings an anamorphic lens to DJI’s drones for cinematic flair

Moment Air

Moment, the company that makes high-quality lenses for smartphones, is expanding its expertise to drones -- specifically the DJI Mavic 2 Pro and Mavic 2 Zoom. The platform is called Moment Air and it doesn't just include lenses, but also filters, a new mounting system, as well as an iPhone case.
The anamorphic lens returns
There's only one lens available at the moment, and it's the Drone Anamorphic Lens. Moment released its cinematography-focused anamorphic lens for smartphones last year, which offers a cinema-wide aspect ratio as well as neat lens-flare effects. This lens delivers the same results, but it has been redesigned with "aerospace-grade composites and metals" -- Moment is calling this "Featherlight" construction -- to ensure it isn't too heavy for the drone.

Amazon worker’s A.I.-powered cat flap stops his pet from bringing in dead animals

How do you stop your beloved pet cat catching and murdering innocent wildlife, then bringing it into your home in the middle of the night and waking you up? There’s plenty of advice out there, ranging from getting sweet little Figaro a collar with a bell, to disincentivizing the act by quickly disposing of dead critters without making a fuss. Of course, if you’re a technically minded Amazon employee, there’s another option too: You rig up your cat flap to an A.I.-enabled camera and Arduino-powered smart locking system. You know, the good, old fashioned way.

That’s exactly what Amazon product manager Ben Hamm did recently, after reaching the end of his tether with cute-yet-murderous cat Metric. To create the door locking mechanism, Hamm affixed an Arduino to an electromagnetic bolt that he attached to the cat door. He also set up a camera using Amazon’s AWS DeepLens, a programmable video camera which can run deep learning models locally and take action according to what it sees. He then set about coding his solution using programming language Python and Amazon SageMaker, a managed cloud service that enables developers to build, train, and deploy machine learning models.
