A gyroscope that lies generally in a plane, for detecting rotation rate
about a gyro input axis. The gyroscope has a substrate, and a generally
planar support member flexibly coupled to the substrate such that it is
capable of oscillatory motion about a drive axis that is orthogonal to
the input axis. There is also a generally planar gyro member coplanar
with and flexibly coupled to the support member such that it is capable
of rotary oscillatory motion relative to the support member about an
output axis that is orthogonal to the plane of the members. There are one
or more drives for directly or indirectly oscillating the gyro member
about the drive axis, and one or more gyro output sensors that detect
oscillation of the gyro member about the output axis.
