METER OF ANGULAR POSITION OF ITEM Russian patent published in 2013 - IPC G01C21/10 

FIELD: measurement equipment.

SUBSTANCE: meter comprises two biaxial micromechanical accelerometers installed so that their identical axes of sensitivity are directed horizontally and perpendicularly, and opposite ones - to opposite sides. Opposite outputs of accelerometers via buffer operational amplifiers are connected to differential inputs of amplifiers of voltage difference, where zero signals of accelerometers are compensated, useful signals of accelerometers are identified and doubled. Outputs of differential amplifiers are connected to appropriate inlets of analogue-to-digital converters of the microcontroller.

EFFECT: increased sensitivity and accuracy of angle measurement, reduced temperature error and increased noise immunity.
