Abstract: An interactive electronic device having a master integrated circuit, an analog audio output device and a bus having a single-conductor digital data link and a single-conductor analog data link and a method for transmitting digital data and an associated analog signal are disclosed. The bus is configured to electrically simultaneously couple the master integrated circuit with any combination of a plurality of removable electronic cartridges arranged in any order in any of a plurality of removable cartridge connectors. The master integrated circuit transmits along the digital data link simultaneously to each of the removable cartridge connectors one identification code of a plurality of identification codes, the identification codes being different from any memory address in any of the removable cartridges. The analog data link simultaneously couples all of the removable cartridge connectors with the analog audio output device and transmits analog signal associated with the one identification code.

Abstract: A magnetically coupled toy system having two toy components such as a doll and nursing bottle is shown. The nursing bottle contains a motor-driven rotating permanent magnet in the nipple portion. A second permanent magnet is mounted in a flexible region around the mouth of a doll. When the nipple containing the rotating magnet is placed in proximity with the mouth of the doll, relative motion between the magnets imparts motion to the mouth and lip regions of the doll.
