How to See the Unseen City

In 1870, quirky inventor Alfred Ely Beach unveiled a 90-meter stretch of New York City’s first subway. In his mind, the future of urban transportation lay underground—in the form of a pneumatic train. Beach’s idea was to expand the then-operational pneumatic mail system—a network of underground tubes that used pressurized air to send mail zipping through the city—into human-size mass transit.

Acer, the world’s fifth largest PC brand, wants to take the growing AR/VR market by the horns with its SpatialLabs glasses-free stereoscopic 3D displays.

First teased in 2021 in a variant of Acer’s ConceptD 7 laptop, the technology expands this summer in a pair of portable monitors, the SpatialLabs View and View Pro, and select Acer Predator gaming laptops. The launch is paired with AI-powered software for converting existing 2D content into stereoscopic 3D.

DARPA Wants a Better, Badder Caspian Sea Monster

Liberty Lifter X-plane will leverage ground effect

Arguably, the primary job of any military organization is moving enormous amounts of stuff from one place to another as quickly and efficiently as possible. Some of that stuff is weaponry, but the vast majority are things that support that weaponry—fuel, spare parts, personnel, and so on. At the moment, the U.S. military has two options when it comes to transporting large amounts of payload. Option one is boats (a sealift), which are efficient, but also slow and require ports. Option two is planes (an airlift), which are faster by a couple of orders of magnitude, but also expensive and require runways.

To solve this, the Defense Advanced Research Projects Agency (DARPA) wants to combine traditional sealift and airlift with the Liberty Lifter program, which aims to “design, build, and flight test an affordable, innovative, and disruptive seaplane” that “enables efficient theater-range transport of large payloads at speeds far exceeding existing sea lift platforms.”

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.
