All solid-state LiDAR sensor that sees 360 degrees

Picture illustrating the generation of the full-space structured light. Credit: POSTECH The LiDAR sensor, which recognizes objects by projecting light onto them, functions as eyes for autonomous vehicles by helping to identify the distance to surrounding objects and speed or direction of the vehicle. To detect unpredictable conditions on the road and nimbly respond, the…

Borrowing a shape from a to-go cup lid, a drone wing could learn how to sense danger faster

Researchers have discovered a new possible use for the dome shape that you would find on a to-go cup lid. Patterns of these invertible domes on a drone’s wings would give it a way to remember in microseconds what dangerous conditions feel like and react quickly.

One way to make antennae that work at tens of gigahertz—the frequencies needed for 5G and…

Fully immersive virtual simulations can boost industrial accident prevention

Structure of the VR-ACM. Cited from Dhalmahapatra et al., (2020). Credit: https://osuva.uwasa.fi/handle/10024/14553 Industries must embrace 3D modeling with fully immersive virtual simulations in their occupational safety management systems. According to a new study from the University of Vaasa, Finland, this will help them to optimize accident prevention. The benefits of VR (Virtual Reality) technology stem…
