Pendulous oscillating gyroscopic accelerometer
First Claim
Patent Images
1. A pendulous oscillating gyroscopic accelerometer, comprising:
- a disc member unbalanced with respect to an input axis;
a torque summing member to which said disc member is mechanically coupled;
means for oscillating said disc member about a reference axis, the oscillation having a first amplitude and a first frequency;
a gyroscope case;
a pair of pivot mounts for pivotably mounting said torque summing member and said disc member to pivot on an output axis perpendicular to the reference axis;
means for resolving an angle of the pivot movement of said torque summing member in relation to said gyroscope case;
a fixed member;
at least one flexure mount for pivotably, flexibly mounting said gyroscope case to said fixed member to allow said gyroscope case to pivot about the input axis perpendicular to the reference axis;
at least one oscillating member for applying torque to said flexure mount to oscillate said gyroscope case about the input axis, the oscillation having a second amplitude and a second frequency; and
means, responsive to said means for resolving, for determining acceleration along the input axis.

Abstract
A pendulous oscillating gyroscopic accelerometer comprising an unbalanced pendulous mass, pivotable on an output axis, that is oscillated about a reference axis transverse to the output axis. The pendulous mass is also oscillated about an input axis transverse to the reference axis, and the acceleration force along the input axis is determined from at least one of those oscillations.
