Resistance standards are incredibly useful, but like so many precision references they require regular calibration, ...

We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

Abstract: Wire retention force is an important indicator for evaluating the reliability of wire insertion in electrical connectors. Current approaches to measure this force are mainly relied on spring ...

Abstract: A long-distance, strong-misalignment tolerance seawater capacitive power transfer system with two insulated electric-field couplers and single-wire for underwater sensors is proposed in this ...
