Abstract
A child's toy having a wireless transmission unit mounted in a first object, such as a doll, and a receiver unit mounted in a second object, such as another doll. The transmission unit includes a first integrated circuit (IC) for producing at least one of an audible sound and movement of a portion of the first object and an infrared transmission circuit for transmitting an infrared signal at the completion of the action. A receiving unit mounted in the second object includes a receiving circuit for receiving the infrared signal. The receiving unit also includes a second IC for producing at least one of an audible sound and movement of a portion of the second object in response to the infrared signal, thus simulating an interaction, such as a conversation, between the first object and the second object.
