Abstract
Official abstract text for this publication.
A method and system for rate sensitive blanking in a path length control circuit of a gyroscope is provided. The method comprises determining an angular rate of the gyroscope, detecting a zero rate of the gyroscope where one or more single beam signals occur, and determining one or more blanker positions based on the zero rate. A blanker pulse is generated at the blanker positions such that the path length control circuit suspends operation when the one or more single beam signals occur.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for rate sensitive blanking in a path length control circuit of a gyroscope, the method comprising: determining a dither rate and an inertial rate of the gyroscope; detecting a zero rate of the gyroscope where one or more single beam signals occur, wherein the zero rate occurs when the sum of the dither rate and the inertial rate is about zero; determining one or more blanker positions based on the zero rate; and generating a blanker pulse at…
