Claim Text:
1. A Joystick Electronic System (JSE) including: a handle assembly attached to a pivot assembly and rotating about a pivot point; and a force sensing cartridge including a plug and a force sensing resistor, wherein said handle assembly is rotated around said pivot point to bring said pivot assembly into contact with said plug, wherein continued rotation of said handle assembly causes said pivot assembly to exert a downward force on said plug, wherein said force sensing resistor determines the downward force exerted on said plug; and an electromagnetic force feedback system wherein said electromagnetic force feedback system receives an indication of the downward force exerted on said plug and uses said downward force indication to control the amount of downward force required to angularly displace said handle assembly, wherein, once a predetermined angular displacement has been reached by said handle assembly, said electromagnetic force feedback system nonlinearly increases the amount of downward force required to continue angularly displacing said handle assembly.
