In an embodiment, an ion beam profiler center measuring apparatus is releasably mounted to the ion beam profiler and measures a center position of an ion beam profiler using a laser beam. A gear case is provided at the cutting portion and is positioned at one lateral side of the cutting portion. At least one lamp and preferably a plurality of lamps at the distal end of the barrel illuminate the needle and the interior of a patient’s mouth. A method of making a coated heat spreader includes coating the organic surface protectant onto a surface of the heat spreader. The noise cancellation system is further configured to be responsive to detection of the movement of the target by the detecting system and the sensed noise, and to provide a noise cancellation wave to a second space to cover the moving target.
