Methods and compositions for detecting and localizing light originating from a mammal are disclosed. The output shaft assembly carries a pawl which pivots on the output shaft assembly between two positions, one permitting driven rotation of an output shaft of the output assembly in a clockwise direction, and the other permitting driven rotation in a counterclockwise direction. The adaptor module has a first electrical connector for mating with the base media device integral electrical connector and a second electrical connector for mating with the second media device integral electrical connector. An insulation sidewall spacer is formed against the vertical face portion. It also relates to the associated cosmetic process. For this purpose, initially color is sprayed or splashed onto the areas of the workpiece located at the edges, while avoiding any mechanical contact of the workpiece, by means of a device which emits the color, and the edges of the workpiece are subsequently welded together by means of a laser.
