Hardware-in-the-Loop Power Profiling Automation for Consumer Streaming Devices: A Multi-Lab Framework for Regulatory Compliance Validation
Bibliographic record
Abstract
Consumer streaming devices must comply with a growing set of regional energy regulations. In the United States the relevant rules come from the Department of Energy and the California Energy Commission. In the European Union the relevant rule set is the Ecodesign framework for off mode, standby mode, and networked standby. Canada, India, and Japan have their own national programs that reference the same underlying IEC measurement methodology. Each regulation prescribes a set of operating states to measure, and each release of a device requires that the measurements be repeated. Doing this work manually does not scale with the number of devices in the portfolio and the cadence of releases. This paper describes a hardware-in-the-loop power profiling automation framework deployed across two geographically distributed lab locations, onboarding thirty-three streaming stick devices for unattended twenty-four-hour, seven-day-a-week power profiling. The framework integrates programmable AC power meters, programmable USB switching, and infrared remote simulation through a Python orchestration layer. It drives the device under test through the operating states required by each regulation, captures the measurements, and produces the records used in compliance submissions. Empirical results from production deployment show a sixty percent reduction in new product profiling time, from approximately twenty-eight hours to between twelve and fourteen hours per device, a fifty percent reduction in sustenance profiling cycles, and seventy-two percent test case automation across a thirty-nine-case regulatory compliance suite. The paper details the framework architecture, the calibration discipline, and the lessons learned from cross-lab deployment, and provides a reference design for test engineering teams facing similar multi-jurisdictional compliance demands.

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.
