Abstract

An angle measurement device capable of providing both linear and non-linear control transfer functions directly using a shaped, generally convex, magnet and linear magnetic sensors, such as Hall sensors. The shape of the magnet is also used to control and optimize the magnitude of the angle measured. This technique of using a special shaped magnet is also used with digital sensors, such as digital Hall switches and arrays. This angle measurement device can be used in many applications requiring an accurate, robust, reliable (including redundant) but inexpensive method to translate angle displacement into a signal voltage or current. Industrial or military hand controllers, such as joysticks, are but one implementation.
