Simultaneous Visible Light Communication and Distance Measurement Based on the Automotive Lighting [PDF]

open access: yesIEEE Transactions on Intelligent Vehicles, 2019
Visible light communication could be an interesting complement to the IEEE 802.11p-based vehicle-to-vehicle communication systems that are sensitive to interferences and delays in dense traffic scenarios such as platooning. Visible light could also provide a redundant distance measure that is crucial for path control in this application. In this paper,

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

open access: yesAdvanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

A visible light-based system for automotive relative positioning [PDF]

open access: yes2017 IEEE SENSORS, 2017
This paper details a simple relative positioning system based on phase-shift measurement with the vehicles lightemitting diode headlamps and taillights. A simulation study of this system is carried out in a realistic environment. It shows that the longitudinal measurement resolution is 12.4 cm over 18 m whereas the lateral distance can be estimated ...

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...
