Abstract: An optical display system includes a point light source or a linear array of point light sources, and a rotating optical subassembly for directing light from said source or sources to at least one viewing station. Resolution may be increased by providing alternate images which are slightly offset from one another, using mirror surfaces at slightly different angles, or using cylindrical lenses with small angle prisms associated with the optical paths. Cross-polarized polarizing layers may also be employed to provide successive images for 3D imaging. Two viewing stations may be provided, along with circuitry for energizing the light source to provide different images at the two viewing stations.

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.
