A universal suction attachment for pneumatic power tools includes a housing having a tool coupling portion, a duct portion, and a focused outflow portion. Mode-locking may be induced by insertion of a saturable absorber into the cavity and by inserting one or more mode-filters to ensure the oscillation of the fundamental mode in the multi-mode fiber. Also is taught a small pipe centered in the cylinder with the purpose to allow a shaft to be inserted therein. A support rod is rigidly attached to the body substrate. Each of the two clutches includes a clutch drum, a piston that forms a working fluid chamber for which a portion of the clutch drum serves as a cylinder, a plurality of friction plates that engage the clutch drum, and a cancel oil chamber that is disposed on a rear face side of the piston and that cancels a centrifugal oil pressure that acts on the working fluid chamber. The media player then presents the user specific and related actions that are based upon the information presented and allows the user to directly execute their choice of actions.
