Speed Measurement Using Gyroscopic Effects TRIZ Cases

Piezoelectric transducers drive and detect a ring gyroscope while electromechanical feedback cancels quadrature signals and resonance errors.

Digital and Gaussian filtering combine with delay compensation to reduce gyroscope latency and improve optical image stabilizer anti-jitter performance.

A phase-modulation signal exposes quadrature amplitude in the demodulated output, enabling feedback correction without a separate chain.

Phase modulation moves quadrature-error information into a demodulated frequency component, enabling real-time feedback correction without separate chains.

Different groove depths in drive and detection arms improve angular-velocity sensitivity while helping preserve strength and reduce thermoelastic loss.

Defects in vibrating elements and control electronics cause scale-factor error; biased-force servoing improves gyroscopic accuracy.

Calibrate vibrating-element gyroscopes with amplitude servoing and stable quadrature force to reduce harmonic and scale-factor errors.

Servo modules maintain non-zero vibration amplitudes while phase-quadrature forces expose anisotropy errors in angular-speed measurements.

Predictive control and gyroscopes counter actuator-induced pendulum motion, preserving suspended-load positioning during wind and shocks.

Higher-order harmonics linearize pick-off signals in a capacitive gyroscope, reducing angular-rate measurement errors.

A linearizer corrects pick-off signal non-linearities while variable drive amplitude extends the measurable angular-rate range.

This gyroscope uses differential excitation and piezoelectric gauges to reduce proof-mass crowding, noise, and stability trade-offs.

This case uses phase, frequency, and amplitude sensing with anti-phase damping and PLL control to avoid spurious modes during start-up.

A balanced sense-lever architecture controls frame tilt and uses strain gauges to improve sensitivity and reduce quadrature effects.

This gyroscope converts out-of-plane mass motion into in-plane sensing motion to improve scale factor stability and vibration rejection.

This MEMS gyroscope uses skew flexures and fully differential sensing to reject common-mode effects and stabilize scale factor.

A time counter adjusts MEMS gyroscope biasing to limit hot-start overshoot.

This case uses drive-voltage and temperature-dependent compensation to correct parasitic coupling offsets in multi-axis MEMS gyroscopes.

This micro vibrator mounting structure uses a curved surface and guard electrode to reduce interference in capacitance detection.

This case combines rotating twin inertial sensors, dual encoders, and 180-degree reversal to stabilize tilt and rotation measurements.
