Abstract

Claims (43)

1. A display for a vehicle having a first measurable characteristic and a second measurable characteristic, the display comprising:

a movable, elongated indicator; wherein the display is connectable to the vehicle such that the position of the indicator indicates the value of the first measurable characteristic, and the appearance of the indicator is variable to indicate the value of the second measurable characteristic;

wherein the indicator is configured to display a first color and a second color; wherein the indicator displays the first color and not the second color in response to the value of the second measurable characteristic being at or below a first predetermined amount; and wherein the indicator displays the second color in response to the value of the second measurable characteristic being above the first predetermined amount.

2. The display of claim 1 , wherein the indicator is configured to display a third color; wherein the indicator does not display the third color in response to the value of the second measurable characteristic being at or below a second predetermined amount greater than the first predetermined amount; and wherein the indicator displays the third color in response to the value of the second measurable characteristic being above the second predetermined amount.

3. A display for a vehicle having a first measurable characteristic and a second measurable characteristic, the display comprising:

a movable, elongated indicator; wherein the display is connectable to the vehicle such that the position of the indicator indicates the value of the first measurable characteristic, and the appearance of the indicator is variable to indicate the value of the second measurable characteristic;

wherein the indicator is movable about an axis; wherein the indicator is characterized by a plurality of segments, including a lower segment and an upper segment, the upper segment being more distant from the axis than the lower segment;

wherein the lower segment and the upper segment each display a respective initial color when the value of the second measurable characteristic is below a first predetermined amount;

wherein the lower segment displays a first color different from its respective initial color, and the upper segment displays its respective initial color, in response to the value of the second measurable characteristic being greater than the first predetermined amount and less than a second predetermined amount; and

wherein the lower segment displays the first color and the upper segment displays a second color different from its respective initial color in response to the value of the second measurable characteristic being above the second predetermined amount.

4. The display of claim 3 , wherein the second color is different from the first color.

5. A display for a vehicle having a first measurable characteristic and a second measurable characteristic, the display comprising:

a movable, elongated indicator; wherein the display is connectable to the vehicle such that the position of the indicator indicates the value of the first measurable characteristic, and the appearance of the indicator is variable to indicate the value of the second measurable characteristic;

wherein the vehicle has an engine characterized by a variable engine speed, wherein the first measurable characteristic is vehicle speed, and wherein the second measurable characteristic is engine speed.

6. The display of claim 5 , wherein the indicator is configured to display a first color and a second color; wherein the indicator displays the first color and not the second color in response to the engine speed being at or below a first predetermined amount; and wherein the indicator displays the second color in response to the engine speed being above the first predetermined amount.

7. The display of claim 6 , wherein the indicator is configured to display a third color; wherein the indicator does not display the third color in response to the engine speed being at or below a second predetermined amount greater than the first predetermined amount; and wherein the indicator displays the third color in response to the engine speed being above the second predetermined amount.

8. The display of claim 7 , wherein the first color is green, the second color is yellow, and the third color is red.

9. The display of claim 5 , wherein the indicator is movable about an axis; wherein the indicator is characterized by a plurality of segments, including a lower segment and an upper segment more distant from the axis than the lower segment;

wherein the lower segment and the upper segment each display a respective initial color when the engine speed is below a first predetermined amount;

wherein the lower segment displays a first color different from its respective initial color, and the upper segment displays its respective initial color, in response to the engine speed being greater than the first predetermined amount and less than a second predetermined amount; and

wherein the lower segment displays the first color and the upper segment displays a second color different from its respective initial color in response to the engine speed being above the second predetermined amount.

10. The display of claim 9 , wherein the second color is different from the first color.

11. A vehicle comprising:

an engine characterized by a variable engine speed; and

a display including a movable, elongated indicator, the position of which indicates vehicle speed; and wherein the color displayed by at least a portion of the indicator is variable to indicate engine speed.

12. The vehicle of claim 11 , wherein the indicator is configured to display a first color and a second color; wherein the indicator displays the first color and not the second color in response to the engine speed being at or below a first predetermined amount; and wherein the indicator displays the second color in response to the engine speed being above the first predetermined amount.

13. The vehicle of claim 12 , wherein the indicator is configured to display a third color; wherein the indicator does not display the third color in response to the engine speed being at or below a second predetermined amount greater than the first predetermined amount; and wherein the indicator displays the third color in response to the engine speed being above the second predetermined amount.

14. The vehicle of claim 13 , wherein the first color is green, the second color is yellow, and the third color is red.

15. The vehicle of claim 11 , wherein the indicator is movable about an axis; wherein the indicator is characterized by a plurality of segments, including a lower segment and an upper segment more distant from the axis than the lower segment;

wherein the lower segment and the upper segment each display a respective initial color when the engine speed is below a first predetermined amount;

wherein the lower segment displays a first color different from its respective initial color, and the upper segment displays its respective initial color, in response to the engine speed being greater than the first predetermined amount and less than a second predetermined amount; and

wherein the lower segment displays the first color and the upper segment displays a second color different from its respective initial color in response to the engine speed being above the second predetermined amount.

16. The vehicle of claim 15 , wherein the second color is different from the first color.

17. A method for indicating values of a plurality of measurable characteristics of a vehicle having an engine characterized by a selectively variable engine speed, the method comprising:

moving an indicator in response to a variation in the speed of the vehicle; and

changing the appearance of at least a portion of the indicator in response to a variation in the engine speed.

18. A display for a vehicle having an engine characterized by a variable engine speed, the display comprising:

a plurality of markings representing vehicle speeds; and an elongated indicator rotatable about an axis;

wherein the display is connectable to the vehicle such that the position of the indicator with respect to the plurality of markings is indicative of the speed of the vehicle;

wherein the indicator is characterized by a plurality of segments, including a lower segment proximate to the axis, an upper segment more distant from the axis than the lower segment, and a middle segment between the upper and lower segments; and

wherein the indicator is configured such that

the lower, middle, and upper segments each display an initial color when the engine speed is below a first predetermined amount; and
