Latest Patents
One of Nakase's latest patents is a communication system for coexistent base band and broad band signals. This system comprises a transmission path, multiple first data terminal units that output data in the form of pulse signals (base band signals), and several second data terminal units that transmit data as modulated signals (broad band signals). Each broad band signal has a center frequency within a predetermined frequency range. The system also includes low-pass filters connected to the first data transmission units, which cut off high-frequency components of the base band signal at a predetermined cut-off frequency that does not overlap with the broad band signals. Another notable patent is a network system diagnosis system. This method involves a communications network system with a closed ring transmission line and multiple data stations connected through line concentrators. The system allows for the diagnosis of the operation states of the line concentrators by transmitting diagnosis data through the internal ring transmission line.
