DEVICE FOR MEASURING PUSHING MOMENTUM OF ATHLETE Russian patent published in 2012 - IPC G01L5/00 

FIELD: physics.

SUBSTANCE: measuring device has a spring-loaded platform comprising: an ascending board, a loading weight, additional adjustable loading weights for selecting the natural frequency of the platform, a set of parallel springs pressed by bolts to a tray with possibility of their free movement when there is a push at where they are attached to the tray and an electronic measuring circuit as part of a piezoceramic accelerometer mounted on the ascending board, a charge amplifier based on an active high-pass filter circuit with a pulse edge correcting circuit, an active low-pass filter with a pulse peak correcting circuit, a high-time constant peak detector and a display.

EFFECT: rapid and reliable monitoring of peak acceleration of an athlete during push.
