Leveraging Smart Lights for Passive Localization
2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS), 2018 Localization based on visible light is gaining significant attention. But most existing studies rely on a key requirement: the object of interest needs to carry an optical receiver (camera or photodiode). We remove this requirement and investigate the possibility of achieving accurate localization in a passive manner, that is, without requiring objects

Optimal Passive Source Localization for Acoustic Emissions [PDF]
Entropy, 2021 Acoustic emission is a non-destructive testing method where sensors monitor an area of a structure to detect and localize passive sources of elastic waves such as expanding cracks. Passive source localization methods based on times of arrival (TOAs) use TOAs estimated from the noisy signals received by the sensors to estimate the source position.
