Abstract

A remote menuing system uses a control knob to select menu items on a display screen. The menu items may be selected by depressing a switch, the switch being integrated with the control knob. Once the menu item has been selected, an operator may modify the value of the selected item by rotating the control knob. When a desired value is displayed, the item may be set by again depressing the switch integrated with the control knob. The use of an integrated control knob and switch, provides ease of use of a menu system while allowing the integrated knob to be located away from the display screen.

Claims

1. A menu item selection device comprising:

a display device displaying a menu of selectable items;

a microprocessor coupled to the display device and affecting the output of the display;

a control knob coupled to the microprocessor, and providing an electrical input signal to the microprocessor relevant to the state of the control knob, wherein the state of the control knob causes a selectable item of the selectable items to be highlighted on the display; and

a switch configured to cause the highlighted menu item to be selected when the switch is depressed,

wherein the control knob may be further used to change a value associated with a selected menu item by first pressing the switch, which causes the menu item to change appearance, then turning the control knob and wherein the value associated with the selected menu item can be chosen by pushing the switch when the desired value is obtained to make the item active, which causes it to appear in its normal state.

2. The menu item selection device of claim 1, wherein the switch is integrated with the control knob.

3. The menu item selection device of claim 2, wherein the knob has an outer surface that is substantially one of, a truncated conical shape, and a cylindrical shape, having a central longitudinal axis;

and, wherein the switch is a button, the button being inset in the knob and extending substantially along the central longitudinal axis of the knob.

4. The menu item selection device of claim 2, wherein the switch is activated by one of pushing and pulling the knob.

5. The menu item selection device of claim 2, wherein the knob may be used to select items on a multiplicity of menus, the active menu being selected by the operator.

6. The menu item selection device of claim 2, further comprising:

a multiplicity of line select keys,

wherein the line select keys provide an alternative means to make a menu item selection.

7. The menu item selection device of claim 1, wherein the knob has a multiplicity of detents, the detents providing a positive positional feel to an operator turning the knob.

8. The menu item selection device of claim 1, wherein the value associated with a selected menu item is incremented by turning the knob in a first direction and decremented by turning the knob in a second direction.

9. An aircraft having a frame, a propulsion system, a lift generating system, and an operator cabin, the aircraft comprising:

a display device located inside the operator cabin, displaying a menu of selectable items;

a microprocessor coupled to the display device;

a control knob, located inside the operator cabin, coupled to the microprocessor, and providing an electrical input signal to the microprocessor relevant to the state of the control knob, wherein the state of the control knob causes a menu item to be highlighted; and

a switch configured to cause the highlighted menu item to be selected when the switch is depressed,

wherein the control knob may be further used to change a value associated with a selected menu item by first pressing the switch, which causes the menu item to change appearance, then turning the control knob and wherein the value associated with the selected menu item may be chosen, then by pushing the switch when the desired value is obtained to make the item active, which causes it to appear in its normal state.

10. The aircraft of claim 9, wherein the switch is integrated with the control knob.

11. The aircraft of claim 10, wherein the knob has an outer surface that is substantially one of, a truncated conical shape, and a cylindrical shape, having a central longitudinal axis;

and, wherein the button is inset in the knob and extends substantially along the central longitudinal axis of the knob.

12. The aircraft of claim 10, wherein the switch is activated by one of pushing and pulling the knob.

13. The aircraft of claim 11, wherein the knob may be used to select items on a multiplicity of menus, the active menu being selected by the operator.

14. The aircraft of claim 9, wherein the knob has a multiplicity of detents, the detents providing a positive positional feel to an operator turning the knob.

15. The aircraft of claim 14, wherein the knob communicates a digital signal to the microprocessor.

16. The aircraft of claim 9, further comprising:

a multiplicity of line select keys,

wherein the line select keys provide an alternative means to make a menu item selection.

17. The aircraft of claim 9, wherein the value associated with a selected menu item is incremented by turning the knob in a first direction and decremented by turning the knob in a second direction.

18. The aircraft of claim 9, wherein the knob is located on a Display Control Panel (DCP).

19. The aircraft of claim 18, wherein the displayed menus are displayed on a Primary Flight Display (PFD).

20. A method for modifying the operating configuration of an aircraft, the method comprising:

displaying a menu on a screen available to an operator, the menu comprising a set of selectable menu items;

rotating a control knob in a first direction to select a selected menu item from the set of menu items, the selected menu item being distinguished from all others on the screen as being selected;

depressing a switch to activate the selected menu item, the switch being integral in the control knob;

rotating the control knob in one of the first direction and a second direction to adjust a value of the selected item; and

depressing the switch when a desired value is eached, thereby making that value active.

21. The method of claim 20, wherein the values of the selected items displayed are incremented, by an appropriate preset increment, when the knob is rotated in a first direction and wherein the values of the selected items displayed are decremented, by an appropriate preset decrement when the knob is rotated in a second direction.

22. The method of claim 21, wherein the control knob is located on a Display Control Panel (DCP) and the displayed menus are displayed on a Primary Flight Display (PFD).
