A combined monitor and light box
assembly installable in a crib
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 a light
bulb in the box is energized to illuminate the transparency, the image of the mother becomes visible to the infant through the mirror which is then effectively transparent. 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 and hears her comforting message, as a consequence of which the infant is induced to stop
crying. The monitor which is operative only after the switch is activated, radio-transmits the
crying sounds then emanating from the infant to a
receiver that can be heard by the mother.
