Lithium Batteries for Hybrid Cars

Hybrid cars need to travel farther in electric-only mode, and that means lithium-ion battery technologies have a lot riding on them

Chevrolet's Volt is the first series hybrid concept car shown by a major manufacturer. In a series hybrid, the engine's only job is to crank a generator; electric power does all the rest of the work.

In late November General Motors announced plans to release a vehicle that will be able to go long distances in electric-only mode. It thus became the first U.S. company to commit to producing a so-called plug-in hybrid design—one that has batteries so capacious that they can be recharged not only by the engine but also from wall current in the garage. It represents the next way station along the path to an all-electric vehicle.

Engineers Are Working on a Solar Microgrid To Outlast Lunar Nights

Future lunar bases will need power for mining and astronaut survival

The next time humans land on the moon on the moon, they intend to stay awhile. For the Artemis program program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base at which astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.

Trilobite-Inspired Camera Boasts Huge Depth of Field

New camera relies on "metalenses" that could be fabricated using a standard CMOS foundry

Inspired by the eyes of extinct trilobites, researchers have created a miniature camera with a record-setting depth of field—the distance over which a camera can produce sharp images in single photo. Their new study reveals that with the aid of artificial intelligence, their device can simultaneously image objects as near as 3 centimeters and as far away as 1.7 kilometers.

Five hundred million years ago, the oceans teemed with horseshoe-crab-like trilobites. Among the most successful of all early animals, these armored invertebrates lived on Earth for roughly 270 million years before going extinct.

Achieving the next level in vehicle autonomy demands robust algorithms trained to interpret radar reflections from automotive radar sensors. Overcome the gaps between software simulation and roadway testing to train the ADAS / AV algorithms with real-world conditions. Sharpen your ADAS' radar vision with full-scene emulation that allows you to lab test complex real-world scenario, while emulating up to 512 objects at distances as close as 1.5 meters.
