Abstract
Electroencaphalography (EEG) is one of the vital signs monitored during sleep study for patients suffering from obstructive sleep apnea disorder (OSA). OSA is a condition where patients suffer from irregular sleep patterns due to difficulty in breathing. A possible treatment of OSA is use of mandibular advancement devices (MADs). In this manuscript, we present a smart MAD that can monitor intraoral EEG signal. The device acquires intra-oral EEG signal from the mouth-roof. So far very limited research is done in the area of intra-oral EEG monitoring. The proposed smart MAD consists of a MAD, three flexible gold EEG electrodes and an EEG measurement system implemented on a flexible polymide substrate. The measurement system is battery operated and sends EEG data wirelessly using a BLE 5.0 transceiver. The system is validated by acquiring intra-oral EEG signal for "eye-open" and "eye-close" activities of five volunteers. The frequency domain analysis of the intra-oral EEG signal clearly shows that "eye-open" and "eye-close" activities can be detected from the data. In future, this smart MAD will be used to acquire intra-oral EEG data during sleep for OSA patients and determine sleep stages.

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
