Threshold acceleration value a can be fallen down according to the resultant acceleration a calculated and setting
mwhether person will fall down to compare to judge to wear vest.If a>=a
millustrate and wear vest person will fall down, if a < is a
millustrate and wear vest person can not fall down.If but only like this, then when walking and to take a seat etc. and non-ly fall down action and also can produce same acceleration, likely there is maloperation.Therefore need the angular-rate sensor combinationally using detection body inclination state on acceleration to detect the change of the body gesture of vest wearer, thus eliminate maloperation.
