.. _auto_curve_threems_clip_curve:

*COMPUTE 3MS CLIP*
==================

Computes the 3ms clip value of an acceleration (or force) curve — the highest level sustained for at least 3 milliseconds. Use this worker whenever an injury-criterion or regulatory 3ms clip metric needs to be extracted from a time-history signal.

When to use
-----------

Classification: **process**.

Tagged: ``3ms_clip``, ``acceleration``, ``crash``, ``injury_criterion``, ``signal_processing``, ``time_history``.

     - curve
     - vector
     - —
     - 
     - Input time-history curve (e.g., acceleration vs. time) on which the 3ms clip will be computed; must be a two-column vector [time, value].
   * - time_sf
     - time_sf
     - scalar
     - 1.0
     - 
     - Scalar scale factor applied to the time axis before computing the 3ms clip (default 1.0 — leave at default when the curve time is already in milliseconds).
