Google fetes 40 years of Landsat with new timelapse videos of Earth

DNP Google fetes 40 years of Landsat with new timelapse videos of the Earth

Compared to Landsat, which has been beaming photos of our planet since 1972, Mountain View is a cartographic newb. But Google Earth drove geospatial interest into the stratosphere when it launched in 2005 and, with a billion downloads and counting, the company is well placed to celebrate 40 years of Landsat imagery. To do that, it has collaborated with the US Geological Survey and Carnegie Mellon to create a collection of timelapse videos ranging from seasonal snowcover changes across North America to Amazon deforestation. Though the search giant is gradually shifting from relatively low-res 100 feet per pixel Landsat imagery to 8 feet SPOTImage maps, its Google Earth Engine was used to process the vast archive and make it available to the public. To watch a video of the history of the grand dame of satellite imagery and its liaison with Google, head after the break -- or check the source for all the timelapse goodness.

Carnegie Mellon smart headlight prototype blacks out raindrops for clearer view of the road

DNP Carnegie Mellon headlight prototype blacks out raindrops for clearer view of the road

Researchers from Carnegie Mellon have developed a prototype smart headlight which blots out individual drops of rain or snow -- improving vision by up to 90 percent. Made with an off-the-shelf Viewsonic DLP projector, a quad-core Intel Core-i7 PC and a GigE Point Grey Flea3 camera, the Rube Goldberg-esque process starts by first imaging raindrops arriving at the top of its view. After this, the signal goes to a processing unit, which uses a predictive theory developed by the team to guess the drops' path to the road. Finally, the projector -- found in the same place as the camera -- uses a beamsplitter like modern digital 3D rigs. Used in tandem with calculations, it transmits a beam with light voids matching the predicted path. The result? It all stops light from hitting the falling particles, with the cumulative process resulting in the illusion of a nearly precipitation-free road view -- at least in the lab. So far, the whole process takes about a hundredth of a second (13 ms) but scientists said that in an actual car and with many more drops, the speed would have to be about ten times quicker. That would allow 90 percent of the light located 13 feet in front of the headlights to pass through, but even at just triple the speed, it would give drivers a 70 percent better view. To see if this tech might have a snowflake's chance of making it out of the lab, go past the break for all the videos.

Carnegie Mellon researchers develop robot that takes inventory, helps you find aisle four

Carnegie Mellon researchers develop robot that takes inventory, helps you find aisle four

Fed up with wandering through supermarket aisles in an effort to cross that last item off your shopping list? Researchers at Carnegie Mellon University's Intel Science and Technology Center in Embedded Computing have developed a robot that could ease your pain and help store owners keep items in stock. Dubbed AndyVision, the bot is equipped with a Kinect sensor, image processing and machine learning algorithms, 2D and 3D images of products and a floor plan of the shop in question. As the mechanized worker roams around, it determines if items are low or out of stock and if they've been incorrectly shelved. Employees then receive the data on iPads and a public display updates an interactive map with product information for shoppers to peruse. The automaton is currently meandering through CMU's campus store, but it's expected to wheel out to a few local retailers for testing sometime next year. Head past the break to catch a video of the automated inventory clerk at work.

Robot Can Use the Microwave, Begun These Hot Pockets Wars Have

Posted on by

Robots can do all kinds of crazy things. They can save our lives in disaster situations, they can clean our homes, they can kill in wartime and now they can use microwaves. No, not as sensors or weapons. They can use the microwave to cook a meal. That they can’t eat. Yet.

This robot’s name is HERB, the Home Exploring Robot Butler. He comes from Carnegie Mellon’s Robotics Institute. As part of his training to become a better home exploring robot butler, he has learned to use a microwave. Well, he can at least microwave frozen food.

With robots being able to microwave frozen foods, lazy people like me have absolutely nothing left to do for ourselves – other than to buy robots.

New shear touch technology lets you skip a double-tap, push your device around (video)

Shear touch on Engadget's site

Most every touchscreen in the market today can only register your finger input as coordinates; that's fine for most uses, but it leads to a lot of double-taps and occasionally convoluted gestures. A pair of researchers at Carnegie Mellon University, Chris Harrison and Scott Hudson, have suggested that shear touch might be a smarter solution. Instead of gliding over fixed glass, your finger could handle secondary tasks by pushing in a specific direction, or simply pushing harder, on a sliding display. Among the many examples of what shear touch could do, the research duo has raised the possibility of skipping through music by pushing left and right, or scrolling more slowly through your favorite website with a forceful dragging motion. The academic paper is still far away from producing a shipping device, although a Microsoft doctoral fellowship's partial contribution to funding the study indicates one direction the technology might go. You can take a peek at the future in a video after the jump -- just don't expect a tablet-based Van Gogh this soon.

[Thanks, Chris]
