Judging by available correspondence, we can assume that the matter of the "air drive top-like gyroscope" ended here.
Three accelerometers are equipped in the piezoelectric gyroscope to measure the angular velocity of three directions.
The particular problem that we will address is the assessment of noise properties in the gyroscope from measurements.
Nonetheless, the particular tokens displayed in the pictures (a manicured poodle and a small, light-bulb-shaped gyroscope) were atypical instances.
If they did, a gyroscope would provide no wonder or amusement.
Foucault had used the instrument to show the rotation of the earth and had also predicted that the gyroscope could be used as a compass.
The compass signal is filtered with the output of the gyroscope to estimate the yaw rate bias of the gyroscope on-line.
Finally, we illustrate how density estimation problems arise in the characterization of physical noise in orientational sensors such as gyroscopes.
