Vibrating Gyroscope Electrode Arrangement for Crosstalk Reduction

The patent applies asymmetry by arranging primary driving electrodes and secondary pickoff electrodes in specific asymmetric orientations relative to each other. The primary driving electrodes are positioned at orientations that are not symmetrically opposite to the secondary pickoff electrodes, which breaks the symmetry that would otherwise cause constructive interference of crosstalk voltages. This asymmetric arrangement ensures that crosstalk voltages from different primary driving electrodes do not add up coherently at the secondary pickoff electrode, thereby reducing the overall crosstalk while maintaining simple device structure.

The patent implements preliminary anti-action by pre-positioning the primary driving electrodes and secondary pickoff electrodes in specific orientations before operation. The primary driving electrodes are arranged such that their orientations are deliberately chosen to prevent coherent addition of crosstalk voltages at the secondary pickoff electrode. This pre-configured anti-aligned arrangement ensures that any crosstalk voltages induced by different primary driving electrodes will partially or completely cancel each other out, thereby proactively preventing measurement errors before they occur.

The patent uses asymmetry in the angular orientations of multiple primary driving electrodes relative to the secondary pickoff electrode. By positioning primary driving electrodes at specific asymmetric angles, the patent ensures that the crosstalk voltages induced by each primary driving electrode have different phases and directions. This asymmetric configuration prevents the crosstalk voltages from adding up constructively, thereby allowing multiple primary driving electrodes to be used for reliable vibration excitation without significantly increasing the overall crosstalk voltage at the secondary pickoff electrode.

The patent converts the potentially harmful effect of multiple primary driving electrodes inducing crosstalk voltages into a beneficial outcome. By carefully selecting the orientations of primary driving electrodes, the patent causes the crosstalk voltages from different electrodes to interfere destructively rather than constructively. This transforms what would normally be a harmful accumulation of crosstalk into a beneficial cancellation effect, allowing multiple primary driving electrodes to be used for improved vibration excitation reliability while maintaining low crosstalk levels.
