Abstract: A portable platform system for connecting an external module having a module connector to a portable electronic platform having a flat panel display, a central processing unit and a system bus includes at least two docking bays disposed on a rear side of the flat panel display including at least first, second, and third rails and an electrical connector. An external module of a first width is slid in between the first and second adjacent rails to be secured to the rear side of the fiat panel display, and the module connector is connected to the electrical connector of the docking bay to electrically connect the module to the central processing unit via the system bus.

Abstract: The present invention provides an electronic maze game wherein the player attempts to direct a playing piece through a maze to a goal within the maze. The goal is suitably indicated by a flashing LED on the game board. The position of the goal within the maze changes in a pseudo-random manner. In the preferred embodiment, the object of the game is to score as many goals in the shortest possible time, without passing through any forbidden zone in the maze. The forbidden zone is indicated by a flashing LED of a different color than the goal LED, and periodically changes position within the maze in a pseudo-random manner.

Abstract: An electronic toy doll including electronic circuitry for selectively generating a number of simulation sounds typically associated with a mystic or science fantasy character. In respective operational modes, the sound of wind, the sound of breathing, an eerie pseudo-random sequence of musical notes and sounds representing the operation of a weapon are selectively generated. In a further operational mode, a random one of a predetermined number of responses are provided upon generation of an actuation signal. The random response may be considered to be an answer to inquiries. Preferred circuitry for generating the simulation sounds is described, accessories, adapted for removable interconnection with the circuitry are also described.

Abstract: A toy which, in response to a complex sound such as human speech generates a train of audio pulses. The pulses are psuedo-random with respect to frequency composition and to duration, thus simulating syllabic speech. Provisions are also described whereby the length of the pulse train is made random.

Abstract: A toy vehicle including provisions for generating realistic simulations of an engine operating through a range of gears, squealing tires, and a crash. Provisions are also described for providing a siren simulation. Preferred circuitry for generating such simulation signals is described.

Abstract: A toy flying craft including provisions for generating realistic engine whines in accordance with the attitude of the craft. Provisions for simulating weapons fire are also disclosed.
