A stator blade carrier, particularly for a gas turbine, is provided. The display provides an array of identifiers arranged in rows and columns, with the identifiers corresponding generally to lines or functions of a communication system. The controller summer sums the signals to produce a controller summer signal to a controller summer conditioning module so as to produce a control apparatus control signal to a control apparatus controller so as to direct the control apparatus and thereby direct the object by feedback control along the desired path. The ball has a diameter smaller than the diameters of the holes in the goal unit.
