ACCELEROMETER Russian patent published in 2024 - IPC G01P15/13 

FIELD: measuring equipment.

SUBSTANCE: essence of the invention consists in the fact that the accelerometer additionally includes analogue negative feedback from the output of the angle sensor to the input of the torque sensor through an amplifier with saturation and a low-pass filter, discrete negative feedback from the output of the angle sensor to the input of the comparator through a series-connected amplifier with saturation, a high-frequency filter, a threshold element with an ambiguity zone, an integrator, in addition, the output of the comparison circuit is connected to the input of the electronic switch through a broadband filter and a trigger, and one of the outputs of the reversible binary counter is connected to one of the inputs of the threshold element with the ambiguity zone, and the output of the reversible binary counter is the digital output of the accelerometer.

EFFECT: high accuracy, wider bandwidth of the accelerometer.
