STABILOGRAPH Russian patent published in 1997 - IPC

FIELD: medical engineering. SUBSTANCE: stabilograph has platform 1 installed on several supports 2.1-2.n, strain transducers 3.1-3.n secured to the above-indicated supports, wide-band amplifiers 4.1-4.n connected to strain transducers, resistive analog adder 5 connected to power supply bushes of strain transducers through amplifier 6 and inverting follower 7, and unit 8 which calculates coordinates of center of gravity. Inputs of unit 8 are connected to outputs of wide-band amplifiers 4.1-4.n. Stabilograph has also unit 9 separating the signals of systoles and unit 10 which separates respiration signals. Both of them are connected to output of resistive analog adder 5. Stabilograph includes multiplexer 11 connected to output of units 8, 9 and 10 and series-connected programmed amplifier 12, analog-to-digital converter 13, and control, display and data processing unit 14. EFFECT: higher results analysis. 5 cl, 7 dwg
