A guidance system for unmanned air vehicles

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
Unmanned air vehicle system is composed of control station, payload, air vehicle, navigation and communication subsystems. Among these, navigation and guidance are most important subsystems. By using the lateral and vertical navigation guidance systems, the planned flight transition of the UAV can be realized from departure waypoint to the target.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

Advanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.
