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

As a cyclist appraising an unfamiliar bike, what are the first two things you do? You give the brakes a cursory squeeze, then pick it up. Weight really is the only proper performance metric that ...

Abstract: Because of increasing leakage current and decreasing defective current, reducing testing time while keeping the required accuracy is one of the main I DQQ testing challenges of the new CMOS ...

Abstract: Aiming at the demand of oxygen partial pressure measurement in aerospace and aviation, a tunable diode laser absorption spectroscopy (TDLAS) technique is proposed to realize the oxygen ...
