Abstract
This study introduces a cost-effective system designed to measure the high-frequency radial displacements of cylindrical metal targets. Traditional methods often use capacitance or inductive sensors; however, this research presents a novel application of inductive sensors exploiting flexible planar coils placed on curved surfaces and combined with low-cost inductance-to-digital converters (LDCs). This solution allows for high sampling rates and submicrometric resolution, making it suitable for applications requiring accurate radial displacement vibration monitoring (e.g., milling operations). The experimental setup, including custom planar coils and a dedicated test bench, was implemented to measure radial displacement in the plane perpendicular to the cylinder's axis and validated the system's accuracy and effectiveness. Future works will optimize the calibration process and explore dual-parameter measurement to enhance accuracy.

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
