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: 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: The present invention generally relates to a mechanical structure having electronic circuits that easily and quickly connect together. The mechanical structures may be building blocks which are stackable and reusable. The building blocks may be removably held together by, for example, gravity and/or friction. The building blocks have electronic circuits which may have numerous uses, including, but not limited to educational, industrial and entertainment uses. More specifically, a building block of the present invention may be insert on, and secured to, a second building block. The building blocks may be identical or may have different features which accomplish varying desired functions. For example, a building block of the present invention may have a light and/or sound feature. In addition, the circuitry of the building blocks of the present invention has unique electronic paths which prevent electronic shorts across a power source.

Abstract: A housing used to combine a standard electronic prototype system and a modular block system with stackable connectors to achieve a design system that allows for safe assembly of circuits of a more complex nature than can be achieved by either system alone.

Abstract: Disclosed is a toy like system using snap together parts and modules that easily demonstrates the principles required in making a remote controlled vehicle. The system comprises a wireless microphone comprising a touch tone key pad for transmission of both speech and touch tones; a mounting base that allows attachment of modules on both upper and lower faces; a reusable electronic module that contains a touch tone decoder circuit and has means for attaching to other electronic modules; and a reusable electronic module that contains motor driving and steering circuits and has means for attaching to other electronic modules. Thus, the present invention discloses a system comprising a base member with base-attachable modules, which together function to allow for the construction of a remote controlled vehicle using standard touch tone frequencies.

Abstract: A battery holder containing positive temperature coefficient (PTC) resetable fuse to electronically limit the maximum current that can be drawn from circuits built using reusable electronic component housings. A power supply with similar housing to reusable battery holders, also designed to limit maximum current and perform electrically equivalent to two or more battery holders. A reusable electronic housing with means for attaching any two leaded electronic component for insertion into quick connect assembly system. This housing also contains a positive temperature coefficient (PTC) resetable fuse to electroniclly limit the maximum current that can be sent through the attached two leaded component.
