AMUSEMENT DEVICE COMMUNICATION SYSTEM

摘要

Amusement device communication system (10) includes a communication link (12), a first amusement device (14) and a second amusement device (16). The communication link (12) has a communication medium (13) and a power line communication subsystem. The first amusement device (14) has a video touchscreen (15a), and the second amusement device (16) has a controller (U3) and a memory (U4). The second amusement device (16) is coupled to the first amusement device (14) by the communication link (12), and the first amusement device (14) communicates with the second amusement device (16) using the communication medium (13). The power line communication sub-system (111) includes a local power grid (109) and first and second power line adapters (118, 120). The local power grid (109) is configured to supply electrical power to local devices. The first power line adapter (118) is coupled between the first amusement device (14) and the local power grid (109). The first adapter (118) superimposes communication signals onto the local power grid (109) and decodes superimposed communication signals from the local power grid (109).
