DEVICE FOR MEASUREMENT OF ACCELERATIONS Russian patent published in 2008 - IPC G01P15/13 

FIELD: mechanics.

SUBSTANCE: invention proposes a sensitive element in systems of stabilisation, navigation and guidance to be used in compensation-type devices of measurement of mechanical magnitudes. The device contains a sensitive element, a pickup of angle, a wideband amplifier, a pick of moments, a positive feedback from the amplifier output to the first converter input, a voltage-to-current converter via the phase detector of the positive feedback, a negative feedback from the amplifier output to the second voltage-to-current converter via the negative feedback phase detector and the filter of upper frequencies, a negative integrating feedback from negative feedback phase detector output to the sign switch input, and, also, a constrained nonlinear component from the output of the positive feedback phase detector to the input of the first voltage-to-current converter and a nonlinear no-sensitivity zone component from the output of the upper frequencies filter to the input of the second voltage-to-current converter.

EFFECT: nonlinear components in positive and negative feedback allows increasing the accuracy of measurement.
