Abstract
Heart rate (HR), the number of heart beats every minute, is the most relied upon vital sign for detecting health deterioration. It is no surprise, then, that the recording of HR is required in sleep studies as well. However, the standard monitoring method, the electrocardiogram (ECG), can be uncomfortable and intrusive, especially during sleep. Here, we present an HR monitoring system that uses the angular rate data from a single axis of a MEMS gyroscope to detect heartbeats. With a mean absolute error (MAE) and standard deviation of the absolute error (SDAE) values of -0.3505bpm and +2.7167bpm, in average, when our tests are compared with a reference ECG signal, we show that our system is accurate enough to track HR changes. Furthermore, the simplicity of our proposed approach makes it an ideal candidate for its implementation as a real-time, portable embedded system.

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
