Abstract: An interactive amusement system for use with a variety of juvenile furniture. In one example, an amusement bar is connected to a control unit arranged at one corner of a collapsible play yard. A motion sensor controls the type of sound generated and flashing rate of an array of light on the amusement bar. The amusement system has a play and a nap mode which cooperates with the sensor to change the sound generated and the flashing rate as well as the intensity of illumination. The motion sensor may be a combination infrared (IR) transmitter and receiver. The play yard is usable as either a bassinet or play yard and the sensor is usable with either configuration. The control unit and amusement bar are removable to enable the juvenile furniture to be collapsed to a compact unit.
