Rotational Oblique Physics
We analyze angular acceleration forces on the brain using 45° anvil impact telemetry at 8.0 m/s to evaluate true concussion and axonal shear protection.
Aero-Acoustic Isolation
Microphone sensors installed at the ear canal measure internal decibel pressure at 100 km/h and 130 km/h to uncover real-world highway wind roar.
Dynamic Center of Gravity
Static scale weight is only half the equation. We measure pitch and yaw neck fatigue in sport-tuck, adventure, and upright cruising postures.
Cranial Anatomical Fit
Evaluating EPS taper across Long Oval, Intermediate Oval, and Round contours to eradicate forehead hot spots and sizing mismatches.
