clip
The 3ms criterion commonly used to measure potential for chest injury.
Syntax
clip(vector1, vector2, scalar1, [1|2], [on|off])
Arguments
- vector1
- The time vector of data to analyze (second).
- vector2
- The chest acceleration vector (g).
- scalar1
- Window in millisecond (usually 3ms for chest).
- 1|2
- Return vector type (optional):
- 0|1
- Flag to turn on debug mode and print to the message log (optional).
- 0=off (default)
- 1=on
Example
y = clip(p1w1c1.x*.001, p1w1c1.y/9.81, 3, 1)
x = clip(p1w1c1.x*.001, p1w1c1.y/9.81, 3, 2)
Comments
clip computes the maximum value that the linear interpolation of a time series (typically a chest resultant acceleration filtered to 300 Hz cutoff) meets or exceeds for an interval of at least 3 ms, based on the linearly interpolated time series. A popup window will display the delta time.
