Nonlinear vehicle control esp. for radio controlled models - using nonlinear control signal element requiring no switching, typically variable potentiometer

摘要

The arrangement is for vehicle control, esp. for remote radio control of model vehicles. It uses a non-linear element in the signal transfer chain to give a small gain for small control movements and a larger gain for larger movements without requiring a gain switching mechanism. The transfer function of the whole signal transfer chain is non-linearised by the use of one non-linear element which may be electrical or mechanical. The element may consist of a potentiometer with variable metal deposition thickness giving variable resistance change for control movement.
