CONTROL DEVICE
First Claim
Patent Images
1. A control device comprising:
- a reference frame;
a stick;
a pivot mounting the stick to the reference frame and defining a pivot axis; and
an actuator for rotating the stick about the pivot axis, wherein the actuator and the stick are offset from the pivot axis such that if the control device is subjected to an acceleration orthogonal to the pivot axis, then the mass of the actuator and the mass of the stick generate moments about the pivot axis which act in opposite directions.

Abstract
A control device comprising: a reference frame; a stick; a pivot mounting the stick to the reference frame and defining a pivot axis; and an actuator for rotating the stick about the pivot axis. Mass balance is achieved by offsetting the centres of mass of the actuator and the stick from the pivot axis. Typically a line joining the centres of mass of the actuator and the stick substantially passes through the pivot axis. The actuator is a rotary actuator having a stator coupled to the stick and a rotor coupled to the reference frame.
