A switch mode power supply system includes a rectifying circuit for coupling to an AC input voltage and a transformer having a primary winding for coupling to the rectifying circuit and a secondary winding coupled to the primary winding. These elements allow a search of objects in the database which is similar to the human thinking process. A connector is provided for connecting the electric motor to an external power source, and has a terminal. The tube has at least one aperture in the free end andor on the peripheral surface thereof for providing fluid communication between the tube and the chamber. The clippers are retained in sufficiently spaced relation to permit the cords to be folded or coiled and stored in the clipper compartment during transport.
