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

Abstract: A 256 × 256 single-photon avalanche diode image sensor operating at 100kfps with fill factor of 61% and pixel pitch of 16 μm is reported. An all-nMOS 7T pixel allows gated operation down to ...

The iconic sleep-tracking smart ring is accurate and comfortable—but smart rings make poor activity trackers.

Abstract: Traditional absolute angular displacement sensors usually cannot meet the requirements of high measurement accuracy, low environmental sensitivity, and operation in small space at the same ...
