Title: Arvind K Srivastava: Innovator in Accelerometer Technology

Introduction

Arvind K Srivastava is a notable inventor based in Brentwood, CA (US). He has made significant contributions to the field of accelerometer technology, holding a total of 3 patents. His innovative work focuses on enhancing the performance and accuracy of accelerometers through unique designs and methodologies.

Latest Patents

One of his latest patents is for a resonantly vibrating accelerometer driven in multiple vibrational modes. This inventive accelerometer includes a proof mass and a pair of vibrating sensors. An excitation-and-detection circuit drives one sensor at resonant frequencies f and F, with f≠F. A second excitation-and-detection circuit drives the other sensor at the same resonant frequencies. The vibrational modes driven at these frequencies are consistent for each sensor. Compressive or tensile loads applied by the proof mass to the vibrating sensors cause a difference frequency ΔF=F−F to vary monotonically with acceleration, allowing for precise measurement of acceleration along a sensing axis.

Another significant patent by Srivastava is for a resonantly vibrating accelerometer with cross-coupling signal suppression. This accelerometer also includes a proof mass, vibrating sensors, and an excitation-and-detection circuit. The vibrating sensors are substantially identical and exhibit corresponding fundamental and higher-order vibrational modes characterized by their resonant mode frequencies. The excitation-and-detection circuit drives each sensor at one of its resonant mode frequencies. Compressive or tensile loads applied by the proof mass to the vibrating sensors result in a difference frequency Δf=f−f that varies with acceleration along the sensing axis. The circuit includes at least one low-pass filter with a cut-off frequency that is less than Δf, enhancing the device's performance.
