|20140160548||MULTIDIMENSIONAL ROTARY MOTION APPARATUS MOVING A REFLECTIVE SURFACE AND METHOD OF OPERATING SAME - 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.||06-12-2014|
|20140027359||Filter Loading - A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and a filter arrangement in fluid communication with the pump. The pumping system can also include means for determining a load value indicative of an unclogged filter that permits movement of water through the filter arrangement, means for determining a load value indicative of a clogged filter that inhibits movement of water through the filter arrangement, and means for determining a performance value of the pumping system. The pumping system also includes means for determining a relative loading value of the filter arrangement, means for displaying the relative loading value, and means for controlling the motor in response to the relative loading value. In one example, the load values and performance value can include flow pressure values. A method of moving water of a swimming pool is also disclosed.||01-30-2014|
|20080207043||Strain relief devices - A strain relief device can include at least one mounting tab including a first mounting surface facing a first mounting surface direction and a second mounting surface facing a second mounting surface direction opposite the first mounting surface direction. The strain relief device can further include first and second clamping surfaces that face in diverging directions and extend along a substantially V-shaped profile. Apparatus are also provided that include a first strain relief device and a second strain relief device configured to be selectively mounted with respect to the first strain relief device in a first orientation to provide a first clamping area and a second orientation to provide a second clamping area.||08-28-2008|
