MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091243 A) filed by Israel Aerospace Industries Ltd. on July 27, 2026, for Combined Digital-Analog Two-Beam Vibrating Accelerometer Having Linear Output Across Complete Range.
Inventor includes Gruver, Jose Luis.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A vibrating beam accelerometer (10) can be modelled mathematically as a system having two beams (11, 11') operating in a differential push-pull mode, such that each of the two beams vibrates at corresponding first and second frequencies of vibration (f+, f-) at which the respective amplitude (A+, A-) is dominant outside a predetermined lock-in zone within which the respective dominant frequencies (f1, f2) of the first and second beam are equal. Acceleration is determined inside a predefined range that includes the lock-in zone, as a function of measured vibration amplitudes of the two beams. Outside the predefined range, acceleration is derived as a function of a difference between the measured vibration frequencies of the two beams.
