High Temperature Magnetic Sensors for the Hot Section of Aeroengines
Aerospace, 2021 Magnetic sensors are widely used in aeroengines and their health management systems, but they are rarely installed in the engine hot section due to the loss of magnetic properties by permanent magnets with increasing temperature.

Vehicle Classification Using the Discrete Fourier Transform with Traffic Inductive Sensors
Sensors, 2015 Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management systems. This paper shows that some spectral features extracted from the Fourier Transform (FT) of inductive signatures do not depend on the vehicle speed.
