Latest Patents

One of Uehara's latest patents is a data communication system and electronic control unit used therein. This innovation involves a data communication system where multiple nodes are connected to a common data bus, allowing for seamless communication. The data frame transmitted from a node includes a message of variable length, which is interposed between a signal indicating the length of the message and a signal indicating the end of the message. The coding of the message and signals follows a specific rule, such as NRZ, and employs a bit stuffing rule. This system ensures that even if the message length changes due to noise during transmission, the end signal is clearly detected at the receiving end. This is achieved because it is coded differently from the message and other signals, allowing for reliable detection of transmission errors.
