Abstract

A navigation system provides sensors and a user interface mounted in a single unit while allowing individual users to make adjustments to the user interface without affecting the functionality of the device. This is accomplished by mounting the orientation sensitive sensors (e.g. accelerometers, gyros, etc) rigidly to a mounting bracket rigidly mounted to the vehicle (such as to the dashboard). The sensors are mounted within a ball rigidly mounted to the bracket and the ball is secured within a rotatable socket on the user interface enclosure. In this manner, the user interface enclosure can rotate on the ball, but the orientation of the sensors relative to the vehicle will remain the same.

Claims

1. A navigation system comprising:

a bracket for rigidly connecting to a vehicle;

a ball extending rigidly from the bracket;

at least one sensor rigidly mounted to the ball;

a housing having a socket rotatably connected to the ball; and

a display mounted to the housing.

2. The navigation system of claim 1 wherein the at least one sensor includes an accelerometer.

3. The navigation system of claim 1 wherein the at least one sensor includes a gyro.

4. The navigation system of claim 1 further including a processor within the housing, the at least one sensor connected to the processor.

5. The navigation system of claim 4 further including a map database stored within the housing and accessible by the processor for navigation.

6. The navigation system of claim 5 wherein the display provides a user interface generated by the processor.

7. The navigation system of claim 6 wherein the at least one sensor includes an accelerometer.

8. The navigation system of claim 7 wherein the at least one sensor includes a gyro.

9. The navigation system of claim 8 wherein the at least one sensor includes a GPS receiver.

10. The navigation system of claim 1 wherein the ball is connected to the bracket by a lockable, pivotable joint.

11. A mounting bracket assembly comprising:

a bracket for mounting to a vehicle;

a ball mounted to the bracket; and

at least one sensor mounted within the ball.

12. The mounting bracket of claim 11 wherein the at least one sensor includes an accelerometer.

13. The mounting bracket of claim 11 wherein the at least one sensor includes a gyro.

14. The mounting bracket of claim 11 further including a flexible cable extending from the at least one sensor.

15. The mounting bracket of claim 11 wherein the ball is connected to the bracket by a lockable, pivotable joint.

16. The mounting bracket of claim 11 wherein the at least one sensor includes a GPS receiver.

17. A navigation system comprising:

a bracket assembly for connecting to a vehicle;

at least one sensor mounted to the bracket assembly;

a housing pivotably connected to the bracket assembly; and

a display mounted to the housing.

18. The navigation system of claim 17 wherein the at least one sensor includes an accelerometer, such that the accelerometer maintains a constant orientation relative to the vehicle and the bracket assembly throughout a range of pivoting between the housing and the bracket assembly.

19. The navigation system of claim 18 wherein the at least one sensor includes a gyro.

20. The navigation system of claim 18 further including a processor within the housing, the at least one sensor connected to the processor.

21. The navigation system of claim 20 further including a map database stored within the housing and accessible by the processor for navigation.

22. The navigation system of claim 21 wherein the display provides a user interface generated by the processor.

23. The navigation system of claim 17 wherein the at least one sensor is at least partially disposed within the housing.

24. The mounting bracket of claim 17 wherein the at least one sensor is connected to the bracket by a lockable, pivotable joint.

25. The mounting bracket of claim 17 wherein the at least one sensor includes a GPS receiver.
