Abstract: A stereoscopic video display device includes a left and a right video display for viewing by respectively the left and right eye of a viewer, a video driver circuit which alternates between driving the left video display and driving the right video display, and a view control circuit for providing a left-right signal which indicates which video display is currently displaying the video signal. A video signal source, such as a computer or a video game console, receives the left-right signal and provides a standard video signal. The stereoscopic display is usable with a source that provides a video signal that represents a left or right view according to the left-right signal, or with a source that ignores the left-right signal and provides a monoscopic video signal. The stereoscopic display is operable in both a stereo and a mono mode so that a user can select either monoscopic or stereoscopic video when the source is capable of providing stereoscopic views.

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.
