// ACC
glow - // near-zero-g entry threshold (in 0.1g)
gspike - // tolerated spike ceiling inside dwell (in 0.1g)
ghigh - // hysteresis exit threshold (in 0.1g)
tmin - // dwell duration (in 0.01s)
p - // required fraction below g_low (in %)
ambigmax - // allowed samples in [g_low, g_spike) within free-fall window (in pcs)
exithold - // time above g_high to exit free-fall state (in ms)
iirtau - // 1st-order LPF on SVM; <=0 to disable (in ms)
// IMPACT
impths - // acceleration spike threshold for impact (in 0.1g)
impwin - // window to detect impact after free-fall (in ms)
