One-Camera Method Reveals Added Insights in Additive Manufacturing
PITTSBURGH, July 26, 2023 — Thermodynamic insights into the laser powder bed fusion process in additive manufacturing are critical to ensuring the production of quality parts. For example, if too much of the material vaporizes, or the melt pool becomes unstable during the manufacturing processes, manufacturers could end up with entirely different material properties than intended and defects that render the part unusable. Accurate temperature measurements of the melt pool can also be used to predict and identify defect
CMU, Fujitsu Team Up for Dynamic 3D Structure Representation
PITTSBURGH, July 11, 2023 — Researchers from Carnegie Mellon University (CMU) and Fujitsu have developed a method to convert 2D images to a 3D structure. The researchers’ Dynamic Light Field Network (DyLiN) method handles nonrigid deformations and topological changes and...

Wearable Camera Enables Human Motion Capture
TOKYO, Oct. 23, 2020 — Researchers at Tokyo Institute of Technology and Carnegie Mellon University developed a human motion capture system called MonoEye, which consists of a single ultrawide fisheye camera mounted on the user’s chest. The system’s simplicity...
Flexible Parylene Waveguide Operates Over Broad Spectrum
PITTSBURGH, Sept. 23, 2020 — A parylene-based waveguide has the physical characteristics necessary to enable it to emerge as the new standard in optical biointerfaces. Researchers at Carnegie Mellon University developed the highly flexible waveguide, which can additionally...
Self-Driving Cars That Recognize Free Space Can Better Detect Objects
PITTSBURGH, June 16, 2020 — Researchers at Carnegie Mellon University (CMU) have demonstrated that they can significantly improve detection accuracy in self-driving cars by helping the vehicle recognize what it does not see. Self-driving vehicles use 3D data from lidar to...
Infrared Links Could Replace Wires in Data Centers
UNIVERSITY PARK, Pa., Feb. 6, 2017 — A Team of engineers are proposing to eliminate most of the wires in data centers and instead use infrared free-space optics for communications. The Free-space optical Inter-Rack nEtwork with high FLexibilitY — Firefly — architecture is a...

Wave a hand, create a touch screen
Jul 1, 2013 — Smartphone apps can take care of everything but walking the dog (although there may be an app for that, too). It’s convenient, sure, but you have to dig your phone out of your pocket, and you’re stuck with the interface designed by an...
Football + camera = touchdown!
May 1, 2013 — Some football fans can never get close enough to the action – even if they happen to score front-row seats on the 50-yard line, they want to be right on the astroturf instead. For those fans, there’s BallCam. The prototype,...
I can’t see the rain … against my headlights
PITTSBURGH – Driving at night through a downpour or a heavy snowstorm could become much easier if a sophisticated headlight system created at Carnegie Mellon University’s Robotics Institute becomes commercially viable. A camera, computer chip and an...
Headlights Shine Between – Not Through – Raindrops
