ACCELEROMETER Russian patent published in 2024 - IPC G01P15/14 

FIELD: measurement.

SUBSTANCE: invention, an accelerometer, is intended for use as an element in stabilization and navigation systems and in medicine. Accelerometer includes analogue negative feedback from the output of the angle sensor to the input of the torque sensor through the first integrator, amplifier with saturation, broadband filter, output of amplifier with saturation is connected to threshold element with ambiguity zone, in feedback of which differentiating filter and second integrator are included, discrete negative feedback from the output of the threshold element with the ambiguity zone to the input of the comparator, the output of the reverse binary counter is the digital output of the accelerometer. Introduction of analogue and discrete negative feedbacks into the accelerometer makes it possible to implement the mode of stable self-oscillations, increase the transmission coefficient along the open circuit, increase the measurement accuracy and expand the pass band.

EFFECT: high accuracy and wider bandwidth.
