Multidimensional rotary motion apparatus moving a reflective surface and method of operating same
First Claim
1. A motion control system controlling a mirror element within an underwater projection system in a water feature, pool, or spa, the system comprising:
- a first drive mechanism and a second drive mechanism;
a first cam mechanism driven by the first drive mechanism and a second cam mechanism driven by the second drive mechanism;
a first input shaft coupled to and driven by the first cam mechanism and a second input shaft coupled to and driven by the second cam mechanism; and
a mirror support member having a mirror element thereon coupled to the first input shaft, the mirror support member restrained by a first restraint mechanism so as to move about a moment in a first direction by the first input shaft, the mirror support member also restrained by a second restraint mechanism through the first restraint mechanism, so as to move the mirror support member about a moment in a second direction by the second input shaft acting on the second restraint mechanism through the second cam mechanism and the second drive mechanism, and this movement is imparted in the mirror support member and the mirror element mounted thereon which in turn guides an image from the underwater projection system within the water feature, pool or spa.

Abstract
A rotary motion controller controlling the motion of a mirror in a projection system is described having a mounting element coupled to a support member. A two-axis coupling is provided with at least two input shafts coupled to two drive mechanisms. A channeled portion is provided in a second of the two input shafts through which the support member extends there through and is guided thereby and where the at least one support member is coupled to the first input shafts via an input coupling coupled to and driving the support member and a control input controlling the position of the at least two input shafts. A method of controlling a mirror in an underwater projection system is also provided along with a method of operating a controller for an underwater projection system and a further embodiment for providing movement of a mirror in an underwater projector.

11. A motion control system controlling a mirror element within an underwater projection system in a water feature, pool, or spa, the system comprising:
-
a base; a first drive mechanism coupled to the base; a second drive mechanism coupled to the base; a first linkage coupled to and driven by the first drive mechanism; a second linkage coupled to and driven by the second drive mechanism; and a mirror support member having a mirror element thereon coupled to the first linkage and the base, wherein the mirror support member is coupled to the base by a first restraint mechanism, which limits the motion imparted on the mirror support member by the first linkage to a first plane, and wherein the second linkage acts upon the second drive mechanism to rotate the base and the mirror support member about a second restraint mechanism in a second plane. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
