US Patent Issued to STMicroelectronics International on Dec. 30 for "Precision rate demodulation for a vibrating gyroscope" (Texas Inventors)

ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,510,359, issued on Dec. 30, was assigned to STMicroelectronics International N.V. (Geneva).

"Precision rate demodulation for a vibrating gyroscope" was invented by Pavan Nallamothu (Little Elm, Texas), Milad Alwardi (Allen, Texas), Deyou Fang (Frisco, Texas), Yamu Hu (Allen, Texas) and David McClure (Carrollton, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "According to an embodiment, a circuit is proposed for generating rate and quadrature demodulation signals, incorporating unidirectional hysteresis for negative edges. The circuit features a preliminary stage that amplifies the differential sinusoidal signal from gyroscopic proof mass oscillati...
