Abstract

A motion control system for controlling an image projected from an underwater projection system in a water feature includes a chassis, a mirror support coupled to the chassis, a mirror member on the mirror support, a first drive member, and a second drive member. The mirror member is configured to reflect the image projected from the underwater projection system in the water feature. The first drive member is coupled to the chassis and configured to rotate the mirror support relative to the chassis about a first axis to move the reflected image in the water feature. The second drive member is coupled to the chassis and a fixed mount and is configured to rotate the chassis and the mirror support about a second axis to move the reflected image in the water feature.

Claims

1. A motion control system for controlling an image projected from an underwater projection system in a water feature, the motion control system comprising:

a chassis;

a mirror support coupled to the chassis;

a mirror member on the mirror support, the mirror member configured to reflect the image projected from the underwater projection system in the water feature;

a first drive member coupled to the chassis and configured to rotate the mirror support relative to the chassis about a first axis to move the reflected image in the water feature; and

a second drive member coupled to the chassis and a fixed mount, the second drive member configured to rotate the chassis and the mirror support about a second axis to move the reflected image in the water feature.

2. The motion control system of claim 1, wherein the first axis and the second axis are orthogonal to each other.

3. The motion control system of claim 1, wherein the first drive member is configured to rotate the mirror support in a vertical direction.

4. The motion control system of claim 1, wherein the second drive member is configured to rotate the mirror support in a horizontal direction.

5. The motion control system of claim 1 and further comprising a first rotating cam coupled to the first drive member and a first linkage coupled to the first rotating cam and the mirror support.

6. The motion control system of claim 5, wherein the mirror support is coupled to the chassis by a hinge, and the first drive member is configured to rotate the first rotating cam, which moves the first linkage to rotate the mirror support about the hinge.

7. The motion control system of claim 1 and further comprising second rotating cam coupled to the second drive member and a second linkage coupled to the rotating cam and the fixed mount.

8. The motion control system of claim 7, wherein the chassis is coupled to a pivot pin aligned with the second axis, and the second drive member is configured to rotate the second rotating cam, which moves the second linkage relative to the fixed mount to rotate the chassis about the second axis.

9. The motion control system of claim 1 and further comprising a controller configured to control rotation of the mirror support about the first axis and the second axis.

10. The motion control system of claim 9 and further comprising a sensor in communication with the controller and configured to provide feedback related to a position of the mirror support relative to one of the first axis and the second axis.

11. The motion control system of claim 10, wherein the controller is configured to control rotation of the mirror support about the first axis and the second axis based on the feedback from the sensor.

12. The motion control system of claim 10, wherein the sensor includes a vertical motion sensor and a horizontal motion sensor.

13. The motion control system of claim 1, wherein the first drive member and the second drive member are each coupled to the chassis at stationary positions relative to the chassis.

14. The motion control system of claim 1, wherein the first drive member and the second drive member are one of motors, magnetic drives, piezo drives, and mechanical drives.

15. The motion control system of claim 1, wherein the water feature is a pool.

16. An underwater projection system for a water feature, the underwater projection system comprising:

a projector configured to project an image;

a motion control system configured to reflect the image from the projector within the water feature, the motion control system including

a chassis,

a mirror support coupled to the chassis,

a mirror member disposed on the mirror support,

a first drive member configured to rotate the mirror support relative to the chassis about a first axis to move the reflected image within the water feature, and

a second drive member configured to rotate the chassis and the mirror support about a second axis to move the reflected image within the water feature; and

a controller configured to control rotation of the mirror support about the first axis and the second axis.

17. The underwater projection system of claim 16, wherein the controller is further configured to control the projector.

18. The underwater projection system of claim 16, wherein the first drive member and the second drive member are one of motors, magnetic drives, piezo drives, and mechanical drives.

19. The underwater projection system of claim 16 and further comprising a sensor in communication with the controller and configured to provide feedback related to a position of the mirror support relative to one of the first axis and the second axis, wherein the controller is configured to control rotation of the mirror support about the first axis and the second axis based on the feedback from the sensor.

20. The underwater projection system of claim 16, wherein the first drive member and the second drive member are each coupled to the chassis at stationary positions relative to the chassis.
