FIELD: medical equipment. ^ SUBSTANCE: invention refers in particular to the means for detecting the body movements. The device includes the acceleration sensor set on the user's body, means of pulling out the vertical acceleration component from the output of the acceleration sensor, the device for the vertical component division into high frequency and low frequency components, the means identifying the potential position of the of the peak in case the ratio for the low frequency component energy and high frequency component energy is within the given range that includes the possible position of the peak less than the given value, and finally the device detecting the body movements on the basis of the potential position of the peak. The detecting means consists of the stages that stipulate execution of actions by means of the device. ^ EFFECT: use of the invention enables accurate detection of the body movements in vertical direction as well as frequency of the body movements without any impact of noise. ^ 15 cl, 23 dwg |
