FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment, namely to devices for measuring degree of user's physical activity. Activity meter in first version of implementation contains sensor for detection acceleration on multitude of directions, means for calculation of characteristic acceleration on the basis of output sensor signal and means for calculation of physical exercise intensity during body movement, performed in single period, by characteristic acceleration, as well as filter for elimination of fluctuation of component of static acceleration from outlet sensor signal. Means of calculation of physical exercise intensity is made with possibility to calculate physical exercise intensity with application of multitude of calculation formulas and determines formula of calculation during body movement, performed in single period, on the basis of horizontal component and vertical component of characteristic acceleration. Second version of implementation of activity meter is provided with means of calculation of physical exercise intensity, made with possibility to calculate basing on measurement of body inclination.EFFECT: invention makes it possible to carry out accurate measurement of activity degree during different types of activity, from everyday activity to physical exercise.13 cl, 9 dwgГруппа изобретений относится к медицинской технике, а именно к устройствам измерения степени физической активности пользователя.
