Abstract

The drawing shows a joystick A mounted rigidly to panel 4 of five planar panels 1 to 5. Planar panel 1 is fixed, panel 2 is connected to panel 1 by a hinge C, panel 3 is connected to panel 2 by a hinge D, panel 4 is connected to panel 3 by a hinge E, and panel 5 is connected to panels 4 and 1 by hinges F and G, respectively. Each of the hinges is orthogonally mounted with respect to the adjacent hinge, but, clearly, the hinges are not all in the same plane.

Joystick

The drawing shows a joystick A mounted rigidly to panel 4 of five planar panels 1 to 5. Planar panel 1 is fixed, panel 2 is connected to panel 1 by a hinge C, panel 3 is connected to panel 2 by a hinge D, panel 4 is connected to panel 3 by a hinge E, and panel 5 is connected to panels 4 and 1 by hinges F and G, respectively. Each of the hinges is orthogonally mounted with respect to the adjacent hinge, but, clearly, the hinges are not all in the same plane.

Movement of joystick A results in movement of the panels with respect to fixed panel 1. The rotation of panels 2 and 5 about fixed hinges C and G, respectively, can be measured and the angles theta and Phi, respectively, represent the position of joystick A. By suitably encoding theta and Phi, digital or analog signals, representing the position of the joystick, can be obtained.
