Scientists at the Pacific Northwest National Laboratory (PNNL) in the US have developed non-invasive methods for inspecting nuclear power plants. Using X-ray and advanced sensors, PNNL scientists have ...

An only slightly less simple followup circuit also ratios sensor capacitance to a reference capacitor to measure micrometers…this time linearly. Figure 1 The U1a and U1b cross-coupled Schmidt trigger ...

Abstract: Weight fraction is a key indicator to classify high-density polyethylene (HDPE) bales with or without contamination into different quality categories, which determine the values of the bales ...

Abstract: Capacitive angle sensors cannot meet the current requirements of high-precision angle measurements due to their insufficient resolution. This study examines the dual-domain demodulation ...
