Description:
This application is a continuation of application Ser. No. 08/080,346, filed on Jun. 18, 1993, now abandoned. 
    
    
     BACKGROUND-FIELD OF INVENTION 
     The invention relates to a pacifier with an electronically enhanced display specifically to provide novelty to a pacifier design and or entertainment value to a viewer of the pacifier. 
     BACKGROUND-DESCRIPTION OF PRIOR ART 
     Pacifier devices have been designed to provide for the needs of a parent or infant in a variety of ways. Specifically, an infants needs may be taken care of by designs that provide orthopedically different nipples. Pacifiers have been designed with a ring holder that may aid the infant in motor skills when handling or to provide entertainment. Sound producing devices, U.S. Pat. No. 4,554,919 to Hubert (1985), have also been designed into pacifiers in an attempt to soothe or entertain an infant. A pacifier design with the parent in mind, U.S. Pat. No. 5,109,864 to Lu (1992), has been designed with a built in thermometer that serves the dual purpose of pacifying the infant while providing information about the baby. Yet another pacifier design, U.S. Pat. No. 4,716,902 to Swartz (1988), is provided as an aid to the parent in the act of placing a pacifier into the infants mouth in low or no light conditions. Other design provide for both the entertainment of the infant and the parent by providing the use of decorative face covers designs or by using glow in the dark materials, U.S. Pat. No. 5,007,924 to Jekel (1991). 
     All the pacifier designs heretofore known lack a distinct novelty that is designed to provide for the entertainment of the parent or viewer of the pacifier. Even those designs that attempt to use a visually appealing quality have been limited to plastic figures that lack visual action and are not stimulating to the eye of the viewer. 
     OBJECTS AND ADVANTAGES 
     The pacifier is being used with more confidence by the parent to soothe the baby. It has become an accessory feature and there are many choices of colors and designs. 
     This pacifier uses light emitting diodes to highlight a specific feature of the face cover and is a light-hearted, fun way to include baby in the celebration of the holidays or sporting events, but not limited to those ideas. It is a feature of the present invention to provide a pacifier with a lighted face cover that is used to stimulate and or amuse and or entertain those who view the pacifier.
