Abstract: A method for changing printed material, hereafter called interactive book, is provided. The original interactive book may have imbedded links to an External Dedicated Book Addition. The present interactive book allows for multiple people to be able to constantly update External Dedicated Book Additions for the book and solve problems using hidden codes to receive a reward.

Abstract: An interactive figurine with electrical components is provided. The interactive figurine may have a predetermined background story that is provided to the user upon purchase. The electrical components of the interactive figurine may be, for example, touch sensitive arms and/or legs capable of receiving and/or transmitting energy, audio, and other data from a second source. The interactive figurine may contain a rechargeable power source, lights, a microprocessor and an analog switch for controlling arm and/or leg functions. In an embodiment, an audio transmission may be made through the arm(s). A remote may control various features of the figurine. The figurine may also contain connection means to a hand held device for reprogramming of internal microprocessor.

Abstract: A first conductive strip connected to a package that interacts with and creates a circuit with a second conductive strip connected to a battery-operated product inside the package is provided. The battery-operated product may be tested while in the package by pressing the first conductive strip against the second conductive strip with an electrical break. The first conductive strip eliminates the electrical break and completes a circuit path with the second conductive strip allowing activation of some or all of the electronic parts of the battery operated product located inside the package. Activation occurs without opening the package allowing it to be returned to shelf for sale in a new condition.

Abstract: A miniature universal dynamometer for use in teaching and measuring horsepower of scaled down electronic vehicles and DC generators is provided. The miniature universal dynamometer relates generally to electro-mechanical vehicles that use DC energy and DC generators that produce electrical power. This miniature universal dynamometer relates specifically to vehicles that easily and quickly demonstrate to students and auto workers the design and horsepower used by the electronic vehicles in moving vehicles on various roadways. The device also utilizes a switch which allows the device to measure horsepower required to produce electrical power from a DC generator.

Abstract: The device relates to a circular electronic musical instrument having a keyboard with keys which produces polyphonic musical notes. The device is an organ which covers at least one octave of musical notes. The octaves are aligned in bands of concentric rings located on the top of the instrument. Each band of keys may contain one octave of notes. Notes in a first octave are next to or nearby identical notes in a second octave to make popular chords and songs easy to play. Notes may be played simultaneously which are octaves apart with one hand due to proximity of all the keys. A hand may extend over a centrally located loudspeaker and be used to vary the loudness and produce vibrato effects. A small overlay having information may be easily placed on the top of the keyboard to assist in learning songs by number, color, or other visual aids.
