SPECTRAL INTELLIGENCE FOR PRECISION WELD GUIDANCE
AMS AS7341 spectrometer + audio FFT weld director.
ML-in-the-loop control suggestions like a flight director for your laser.

Like a Flight Director for Your Laser
MENIAH observes spectral emissions and acoustic signatures to generate real-time control suggestions. Enable, observe, or review against recorded telemetry.
CAPABILITIES
11-CHANNEL SPECTROSCOPY
AMS AS7341 captures visible + NIR bands to detect plume composition and temperature in real-time.
AUDIO FFT ANALYSIS
Detect keyhole instability, penetration depth, and spatter through acoustic signatures and mel bands.
ML-IN-THE-LOOP
Tiny MLP model runs int8 ONNX inference on-device. Trained on your welds, tuned for your process.
DIRECTOR SIGNALS
Outputs {up, ok, down} control suggestions with confidence. Hysteresis and clamps keep it safe.
TELEMETRY LOGGING
Parquet-based frame logging with monotonic timestamps. Replay and compare director decisions post-weld.
<200MS LOOP
Real-time control loop: read sensors, featurize, infer, gate, publish. Fast enough to matter.
ARCHITECTURE
Fail-Closed by Design
read_sensors() → spectral + audio in parallel
featurize() → normalize, compute deltas, mel bands
infer() → MLP produces {up, ok, down} with confidence
gate() → hysteresis + rate limits + clamps
publish() → LYDIA or telemetry log
If any step fails, director holds last-known-good.
No inference = no suggestion. Human always in the loop.
