threshold
The threshold is only applicable when the
response mode is set to 2. The response time is
1000 ms when the velocity is greater than this
value, otherwise, it is 500 ms.

a. The number of samples used for smoothing depends on both the update_rate and resp_mode
parameters. For instance, if the update_rate is 5 Hz and the resp_mode is 200ms, the number of
samples used will be 10.
