We tested popular wideband Oâ‚‚ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.
Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxemia) give ...
Abstract: A novel robust approach for permittivity measurements of liquid materials in a wide frequency range is proposed. A high-sensitivity microwave-fluidic sensor is developed enabling direct ...
