Data from the posture algorithm verification showing a stimulation transition including transition ramps and adjustable response timing. Note that activity response is set to be immediate (t1), while registering inactivity requires acceleration staying within the inactivity band for an adjustable interval t2 – t3 (nominally one second for demonstration purposes). Note the ramped transitions of stimulation intensity, a safety measure to avoid subject discomfort [37].
