Pressure mapping system based on guided waves reflection
Bibliographic record
Abstract
In this paper, guided wave interaction is used to develop a pressure mapping system for medical and touch-screen applications. The principle is based on interaction of guided waves in the presence of an added local mass and in the presence of a local pressure. For this purpose, piezoceramics are used for injecting guided waves into a thin structure and to measure the reflected waves due to the presence of an added mass or pressure. SHM imaging algorithms, based on Time-of-Flight or correlation, are implemented in order to obtain cartography of the reflections and deduce the presence, localization and intensity of local contact spots. Analytical models are first derived to assess the critical parameters in order to maximize the reflection of guided waves (first order modes A0 and S0). Validation on a 0.5 mm thick plane glass plate prototype is addressed using 1 actuator and 2 sensors. It is observed that imaging of single pressure spot can be achieved using both A0 and S0 mode around 300 kHz with a resolution of 0.5 mm.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
