A sound producing unit and a light emitting unit are provided in the toy body so as to be actuated when combined proximally with another toy body. According to the invention, data or commands issued by a host system and addressed to a transport master are provided to a system bus interface. The first transmission line may comprise a first and a second end. Further, the push-button switch may include feedback mechanisms, such as LED components and the like that provide a visible feedback of the switch connection, and tactile feedback components that also indicate the switch connection. A time of arrival of one or more signals of the received sequence is calculated using one or more of the received sequence, the time differences among the two or more transmissions, the different center frequencies, information from the two or more data packets, and any carrier phase differences among the two or more transmissions using the receiver device.
