Accelerometer#

Accelerometers measure changes in acceleration using a stable mechanical or electromechanical core. Their behavior is predictable, substrate‑agnostic, and well‑bounded by clear physical principles.

Dimensional Core (SET)#

• Spin: negligible
• Elec: capacitive or piezoelectric sensing
• Temp: stable across typical operating ranges

Why Green‑Zone#

Accelerometers operate in a clean, coherent regime.
Their response curves are well‑characterized, calibration is stable, and environmental sensitivity is low. They map directly to their dimensional core without inference layers.

Regime Notes#

• pos‑regime: linear, predictable, low drift
• Q‑regime: minor thermal or mechanical noise
• neg‑regime: extreme vibration or shock events

Alignment Notes#

Already aligned.
Only edge cases (high‑G events, thermal extremes) require explicit regime boundaries.
