ANGULAR SPEED INDICATOR Russian patent published in 2006 - IPC G01P9/04 G01C19/56 

FIELD: measuring equipment engineering, in particular, transformers of angular speed to electrical signal.

SUBSTANCE: angular speed indicator contains resonator, vibrators systems made thereon, and also systems of primary and secondary oscillation indicators, vibration control system. Output of primary oscillations indicators is connected to input of first input amplifier, to output of which phase shift circuit is connected, including first phase demodulator, first correcting filter, modulator and output amplifier, and also circuit for phase automatic frequency adjustment, consisting of second phase demodulator, second correcting filter, transformer of direct voltage to frequency signal and phase shifter. To output of output amplifier a system of vibrators is connected; system of secondary oscillation indicators is connected to input of second input amplifier. In angular speed indicator an additional secondary oscillations indicators system is made, first and second pulse generators are provided, logical device AND, D-trigger, JK-trigger, clock pulse generator. Output of second input amplifier is connected to input of first pulse generator, output of which is connected to first input of logical device AND, output of modulator is connected to input of secondary pulse generator, output of which is connected to second input of logical device AND, to synchronization input of D-trigger output of logical device AND is connected, inverse output of D-trigger is connected to J-input and K-input of JK-trigger, to synchronization input of which output of clock pulse generator is connected.

EFFECT: increased precision of angular speed measurement, forming of discontinuous output signal of angular speed indicator, simplified construction of same.
