Abstract

A joystick position sensing device has a housing and a pivot ball movably mounted on said housing. The ball defines a prime axis, and a joystick is attached to the ball coaxially with the prime axis. The ball also defines two great circles which are orthogonal to each other and which intersect the prime axis. A groove is partially inscribed on the ball over a portion of each great circle, and a respective follower arm is slidably engaged with each groove. Also, each follower arm is rotatably engaged with a respective potentiometer. Motion of the joystick causes the ball (and grooves) to move, and the follower arms can slide in their grooves, or rotate relative to their potentiometers to adjust the setting of the associated potentiometer, in response to motion of the ball. The system generates a signal representative of the position of the joystick relative to the housing based upon the output signals of the potentiometers.
