ACCELEROMETER Russian patent published in 2018 - IPC G01P15/13 

FIELD: measuring equipment.

SUBSTANCE: accelerometer is designed for use in stabilization and navigation systems. Essence of the claimed technical solution is that, in an accelerometer comprising a sensing element, a reference voltage generator, an angle sensor, an EXCLUSIVE OR (XOR) circuit, a pair of logic elements, torque sensor, negative digital feedback, waiting for synchronous generators, RS-trigger, two pairs of coincidence circuits, synchronization circuit, low-bit reversing binary counter, low-order total register, a converter of digital information into a direct code, a binary multiplier, a sawtooth voltage generator, a negative feedback unit is introduced, from the output of the EXCLUSIVE OR (XOR) circuit to the torque sensor input through the second adder, wherein the output of the angle sensor through the proportional link is connected to one of the inputs of the first adder, the second input of which is connected to the output of an integrating AC amplifier with a stable gain, the output of which is connected to the input of the EXCLUSIVE OR (XOR) circuit, through the first logic element, in addition, from the output of the EXCLUSIVE OR (XOR) circuit to the input of the first precision relay element, an integrator and a third adder, one input of which is connected to the output of the sawtooth voltage generator, and the output is connected to the input of the first precision relay element. Output of the reversible binary counter is the digital output of the accelerometer.

EFFECT: expanded bandwidth and increased accuracy of measuring accelerations.
