Abstract
Prolonged monitoring of breathing under different physical conditions is important in many applications for personal health tracking or in hospitals. Ultrasound technology has been used widely for imaging and diagnosis of the human body. In this work, we introduce the use of ultrasound for human respiratory monitoring. The proposed system measures the respiration rate by capturing ultrasound reflections from heart and surrounding organ motions due to the breathing. This system is based on ultrasound B-mode to measure the Time Of Flight (TOF), amplitude and phase of reflected ultrasound signals generated by piezo sensors working at 1 MHz. Experimental results show that the system can obtain respiratory signal with an accuracy of 89% as compared to a SPR-BTA spirometer. A prototype is designed with low complexity hardware, delivering 89% accuracy of the obtained respiratory signal in comparison to a SPR-BTA spirometer.

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
