Abstract: A method is provided for electrodepositing a coating a conductive workpiece. The method provides for individually switching on or off electrodes both interior to and exterior to the workpiece so as to control the deposition of the coating material on the interior surface and the exterior surface of the workpiece. Further, an electrode having insulating positioners can be utilized to provide for better centering of the electrode in the interior of the workpiece.

Abstract: A device may include a magnifying lens having a focal length that defines a focal plane, a light source providing visible light directed toward the focal plane, and a controller. The controller may be programmed to receive a signal indicative of the distance from the device to an object, cause the light source to emit visible light at a first brightness if the distance is at least substantially equal to the focal length of the lens, and cause the light source to emit visible light at a second brightness, dimmer than the first brightness, if the distance is not at least substantially equal to the focal length of the lens.
