Abstract: A combination musical instrument comprising first and second instrument portions each having first and second sides and a plurality of input devices actuable by a user on one side thereof. The first and second portions are coupled to each other. In one embodiment of the invention, the first portion resembles a keyboard and the second portion resembles a guitar. When the input devices on the guitar portion are actuated, sound files stored in a microcontroller are transmitted through a speaker, producing sounds that resemble those made by a guitar. When the input devices on the keyboard portion are actuated, different sound files are transmitted by the microcontroller through the speaker, producing sounds that resemble those made a keyboard, organ, drums, xylophone or other instrument. In one embodiment of the invention, the keyboard portion is foldable about an axis, concealing the keyboard portion from view.

Abstract: A toy car launcher includes a base which carries a combination of pulleys which cause a slide in an elongated track to be rapidly propelled down a track when a pair of handles are pulled. A car placed on the track is propelled by the slide down the track, gaining velocity until it exits the track and continues its travel. The track is hinged to ease transport and storage.

Abstract: There is disclosed an edge-lit multiple image display device. The device utilizes a plurality of internal-reflecting-light sheets which are provided in a stacked array. Images are formed on the surfaces of the sheets with a coating of a material that changes the density on the internally reflecting surface of its respective sheet. A light source is provided to illuminate the edges of the stacked array of sheets, with a light shield that can be moved to selectively direct the light to one edge at a time of the edges of the sheets in the stack. As the light shield is moved to selectively and alternatingly illuminate the edges of selected sheets in the stacked array, the images displayed on each of the edge-lit plates becomes illuminated, appearing and then disappearing as the light source is applied and then removed from the edge of its respective plate. This can be used to provide an animated display.
