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.

17. A motion control system controlling a mirror within an underwater projection system in a water feature, the system comprising:
-
a first drive mechanism and a second drive mechanism; a first input shaft and a second input shaft coupled to and driven by the first and second drive mechanism, respectively; a channel passing through the first input shaft; and a support member coupled to the second input shaft, wherein the support member passes through the channel formed in the first input shaft and extends to support a mirror mount, the first and second drive mechanisms move the first and second input shafts respectively, and this movement is imparted in the support member and the mirror mount, which in turn supports a mirror in the underwater projection system and guides an image from the underwater projection system within the water feature.

18. A method of controlling motion in a mirror element in an underwater image projection system, comprising:
-
providing a torque input from a first and second drive mechanism on command from a controller; turning a first of two input shafts with said torque input from the first drive mechanism; turning a second of two input shafts with said torque input from the second drive mechanism; measuring the relative degree of turning from each of the two torque inputs and communicating same with said controller; engaging a support member supporting said mirror element through the first of the two input shafts; slidingly engaging with a channel formed in and passing through the second of the two input shafts by the support member passing through the channel; and moving the mirror through said engagement in a controlled fashion based on commands from said controller to steer with said mirror an image in an X axis and a Y axis relative to said water feature from said underwater image projection system based on the measured relative degree of turning in each of the at least two inputs. - View Dependent Claims (19, 20)
