Abstract
A low cost system based on two rigid thin film pressure sensors located on two sections of the handle between the operator hand and the tool handle is developed to evaluate coupling forces on real power tool handles. The proposed system is made of two custom FlexiForce® sensors from Tekscan Inc. and these sensors act as single distributed force sensors and can be trimmed to the desired shape and size. The sensors with its amplifier were calibrated on a flat surface by applying a force distributed over its entire area. The outputs of the sensor, as a function of the force applied on the pressure sensor on a flat surface, are shown. Linear correlation coefficients slightly above 0.99 are obtained for each of the three trials, confirming the linearity of the sensor. The palm sensor responses are found to be a function of push force applied by one of the subjects for three different trials.

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
