Abstract: A joystick with a first casing that has a piece of a sensor/effector pair. A second section is attached to the first casing, where at least one of the first and second casings form a void within the first and second casings. A puck with a cylindrical shape is disposed within the void, where the puck has a piece of the sensor/effector pair. A shaft is connected to the puck, with a distal end free to move, thereby rotating the puck. The shaft passes through a void between the first and second casings, and as the shaft is moved and the puck rotates, an interaction between the pieces of the sensor/effector pair produces a signal indicating a degree of movement of the shaft.

Abstract: A joystick including a main housing with a first control surface and a second control surface. A ball rotationally engages the first control surface. A shaft has a first end that releasably engages the ball. A shoe rotationally engages the second control surface. A main spring has a first end for pressing the shoe against the second control surface. A center lock housing engages a second end of the main spring and houses a slider and a lock spring. The slider selectively permits and prevents movement of the shoe along the shaft. The lock spring presses the slider into a desired default position. A knob releasably engages the second end of the shaft. A boot covers portions of the joystick.

Abstract: A control handle with a mounting portion, having an upper mounting portion and a lower mounting portion. An upper removable portion forms a substantially spherical portion with the upper mounting portion. A control plate is disposed between the upper mounting portion and the lower mounting portion, and control buttons are disposed on the control plate. A lower removable portion forms a substantially cylindrical portion with the lower mounting portion.
