Abstract
This paper presents a novel embedded digital throwing system for synchronously sensing the throwing force of shot-put athletes in real time. The three axes integrated accelerometer, as a crucial device in the force sensing system, can acquire the kinetics data along three orthogonal directions with reasonably high accuracy. The digital shot with almost the same size and weight as the standard shot for open female has been designed, fabricated and implemented. The mechanical structure, signal processing system, and human-machine interface are illuminated in detail. In this manner, the force sensing system serves as a powerful tool for coaches and sports scientists to make scientific researches on professional throwing techniques. It also provides an intuitive and reliable guidance for the throwing athletes to improve their skills.

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
