Abstract
In this paper, a new microwave contactless sensor is presented to monitor the level of volatile organic compound (VOC) in a dry gas stream. The platform is based on two passive ring resonators, which are magnetically coupled where the sensing tag is implemented on a flexible RF substrate. The wireless coupling between the reader and the tag, enables contactless as well as sensitive sensing. The microwave sensor operates at 4 GHz while the distance between the reader and the tag can be extended up to 1.5 cm. To increase the sensitivity of the sensor, VOC polymeric adsorbent beads (V503) are used inside a cylindrical quartz reactor and the tag monitors the adsorption on the V503 bed directly. Various concentrations of Methyl Ethyl Ke-tone (MEK) and Cyclohexane in the range of 250 to 1000 ppm are detected distinctively. The sensor demonstrates a sensitivity of 40 kHz/ppm for MEK and 2 kHz/ppm for Cyclohexane operating as a real-time detector.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
