Latest Patents

One of Zotov's key patents is titled "Utilization of mechanical quadrature in silicon MEMS vibratory gyroscope to increase and expand the long term in-run bias stability." This patent outlines a method for self-compensation of the bias draft of the quadrature signal of a gyroscope. The method combines various sub-methods, including quadrature compensation, to achieve the highest possible stability. The calibration methods described in the patent include a temperature self-sensing algorithm that utilizes the drive-mode resonance frequency for calibration of thermal drift in the mechanical parameters of the system. Additionally, it employs a sideband-ratio approach for direct detection of mechanical drive-mode amplitude, modifies the AC and DC components of the amplitude gain control (AGC) for improved stability, and compensates for thermal drift in the sense-mode pick-off system by utilizing mechanical quadrature. By implementing some or all of these calibration methods, the highest level of long-term in-run bias stability can be achieved.
