A Smart Air Outlet using Shape Memory Alloy Wire Actuators for Temperature-Controlled Metrology Rooms
Bibliographic record
Abstract
Wire actuators made of Shape Memory Alloys (SMA) provide an extremely good force-to-weight ratio, the possibility of flexible system integration and silent operation, making them suitable for a wide range of applications. In this paper, a concept for the use of these actuators in self-regulating (smart) air outlets for a heating and cooling system in industrial metrology rooms is presented and realized as a prototype. The activation of individual air outlets spread across the room results in more even heating or cooling of the entire metrology room particularly for digital metrology and Coordinate Measuring Machine (CMM). The core features of the SMA actuator system within the air outlet are the independent operation from the main thermostat of the heating and cooling system as well as the energy-efficient mechanical and electrical design with currentless rest positions of the air outlet. To achieve a high level of functional integration, the SMA wires required for the actuating movement are embedded directly into the structural components of the individual air outlets inside Polytetrafluoroethylene (PTFE) tubes.

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.
