L.Attorney, Agent or FirmInternational ClassesG05G 9/00 (20060101)G05G 9/047 (20060101) AbstractA joystick includes a pivotably mounted X yoke connected to an X potentiometer and a pivotably mounted Y yoke connected to a Y potentiometer. To permit at least one additional degree of control, a platform member is pivotably mounted one of the yokes to support an additional control element such as a further potentiometer. The pivoting motion of the platform member with respect to the yoke element on which it is mounted is conveyed to the remaining yoke element. Both a platform member and the remaining yoke element pivot about respective axes that are perpendicular to the pivot axis of the yoke element on which the platform member is mounted. | |
