A controller area network (CAN) has a plurality of nodes connected to transmit and receive data over a serial data line. An AC power source is also connected to each node. Each node senses the AC power waveform and synchronizes bit transmission and bit detection with the waveform. In a preferred embodiment,...http://www.google.es/patents/US6373376?utm_source=gb-gplus-sharePatente US6373376 - AC synchronization with miswire detection for a multi-node serial communication system
