Patent US 5,774,861

A mirror and light box assembly installable in a crib or other enclosure occupied by an infant. The assembly which is interactive with the infant includes a light box on whose front face is mounted a semi-reflective mirror behind which is a film transparency having a photographic image of the infant's mother. When an electric light bulb in the box is energized to illuminate the transparency, the image of the mother becomes visible to the infant through the then effectively transparent mirror. Associated with the light box is a sound-activated switching device connected between the bulb and a power source. The switching device, when activated by crying sounds emanating from the infant, remains activated for a predetermined period to energize the bulb and illuminate the transparency. Also associated with the light box is a record playback unit having stored therein a voice message recorded by the mother addressed to her infant, the unit being rendered operative only when the bulb is energized. Hence when the infant cries, it is then presented with an image of its mother as it hears her comforting message, as a consequence of which the infant is induced to stop crying.
