Abstract: A toy figure comprising a hollow body or torso member has at least one extremity receiving socket disposed therewithin having an annular sidewall and a base wall and formed integrally with the body member. The hollow extremities have a projecting socket with an annular sidewall and a base wall which has a depending boss extending into the cavity of the extremity, and a passage extends therethrough. A plug member is seated in the socket and it has a depending finger sealing the passage through the base wall of the socket. A connector engages the outer surface of the socket of the extremity and the inner surface of the socket of the torso to provide a rotatable connection between them. Expanding air pressure in the extremity cavity causes the material of the depending boss to clamp the finger tightly to seal the passage and hold the plug in assembly.

Abstract: A doll contains a flexible sensor which is captured in the doll near a surface thereof and will emit an electrical signal when subjected to bending or pressure to indicate that this part of the doll is being touched or manipulated. The sensor utilizes a film having piezoelectric properties to generate a signal when subjected to such forces.

Abstract: A doll head of flexible self-supporting material having lips and defining a mouth and a motor-driven mouth actuator which moves the lips between open and closed positions to simulate mouth movement and a central processing unit including a speech synthesizing system energizes the mouth actuator motor during synthesized speech, but does not de-energize the mouth actuator motor after a speech phrase until the mouth is in a closed position.
