Abstract: An input system that mounts over a portion of a keyboard, which system may include an input device corresponding to at least one keyboard key covered by the input system. The input device may comprise a key or other input mechanism easily accessible to the user, and at least one of the input mechanisms may functionally correspond to one of the covered keyboard keys. The input mechanisms may be conventional keyboard keys, buttons, touchpads, or any suitable input mechanism. The input system body may comprise a platform elevated over the keyboard, the platform adapted to support a mouse. Alternatively, the input system may comprise an input device that eliminates the need for a separate mouse. Such an input device may include one or more of a trackball, dials or wheels, buttons, digital tablet, touch screen, or any suitable mechanism for inputting information otherwise input by a mouse or other electrical input device. The input system may be integral with, or separate or separable from, the keyboard.

Abstract: A method and cutting device for unwrapping a case, such as a CD or DVD case wrapped in thin packaging material such as cellophane and adhesive tape, the case comprising two adjacent parallel plates defining a profile with a narrow side. The cutting device may comprise a longitudinally extending gripping arm adapted to be gripped at least partially in the palm of a user's hand, a cutting blade adapted to cut packaging material, and a cutting guide attached to the gripping arm, the cutting guide adapted to guide the sharpened tip of the cutting blade along the narrow side of the case. The cutting device has a longitudinal axis which may be held substantially perpendicular to the longitudinal axis of the case during cutting.
