COMPENSATION ACCELEROMETRE Russian patent published in 2011 - IPC G01P15/13 

FIELD: physics.

SUBSTANCE: proposed accelerometre comprises sensitive element with its angular position locked by angle pickup, two integrating amplifiers, moment pickup, two negative feedback circuits, one connecting angle pickup with adder input via integrating amplifier, negative feedback phase detector, differentiating filter, "sensitivity-zone"-element and voltage-to-current converter, all connected via data inputs. Another feedback circuit connects negative feedback detector output with adder input via smoothing filter, second integrating amplifier, comparator, level converter, pair of triggered synchronous generators, reversing binary counter, comparison circuit, threshold element and electronic switch, all connected via data inputs.

EFFECT: expanded bandwidth, higher accuracy.
