COMPENSATORY ACCELEROMETER Russian patent published in 2020 - IPC G01P15/13 

FIELD: stabilization system.

SUBSTANCE: invention is intended for use in stabilization, navigation and in medicine. Into a compensation accelerometer comprising a sensitive element, an angle sensor, a reference voltage generator, an amplifier, an integrator connected to the output of the amplifier, integrating the negative feedback, comparator output is connected to input of comparison circuit through serially connected level converter, two waiting synchronous generators, reversible binary counter, electronic switch, input of which is connected to current generator output, and output with one of moment sensor inputs, summing binary counter, comparison circuit, auxiliary frequency generator, additional inputs of comparator, waiting for synchronous generators, reversible binary counter are connected to auxiliary frequency generator, local negative feedback is introduced from the amplifier output, through the high-pass filter, to one of the moment sensor inputs and the two-position relay element with a hysteresis characteristic from the integrator output to the comparator input, as well as a flip-flop from the output of the comparison circuit to the input of the electronic switch, and the output of the reversible binary counter is the digital output of the compensation accelerometer.

EFFECT: high accuracy and wider bandwidth.
