MOVEMENT DETECTION DEVICE Russian patent published in 2015 - IPC A61B5/113 A61B5/205 G01P15/18 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A method for detecting individual's respiration and/or cardiac function is implemented by means of movement detection. A multiaxial accelerometer is placed on the individual's body. The accelerometer generates signals indicating the acceleration along separate spatial axes. A signal generation unit is used to generate a movement signal by linear combination of the accelerometer signals along the separate spatial axes. The movement signal indicates the individual's respiration and/or cardiac function. The accelerometer signals are weighed so that the accelerometer signal characterised by the maximum acceleration variation has the highest weight. The movement signal generation unit detects the accelerometer signal weight depending on correlation of the respective accelerometer signal and the accelerometer signal characterised by the maximum acceleration variation. The respective accelerometer signal weight is a correlation sign.

EFFECT: using the group of inventions enables increasing the movement signal quality having a high signal/noise ratio.
