Latest Patents

Fukumaru's latest patents include an optical communication method, an optical linking device, and an optical communication system. The system features optical bus-bridging devices that observe the modes of electric buses and optical fibers when the buses are in an OFF mode. This ensures that the modes of the two electric buses connected through optical fibers are synchronized, allowing for simultaneous operation by multiple nodes. When the buses are in an ON mode, an optical output is continuously generated from the driven buses to the optical fibers. During this process, while light is input from the optical fibers, the modes of the buses are not observed, but an electric output is produced to drive the bus. The optical bus-bridging device is designed to change the mode of the electric bus if the optical fiber remains unchanged for a predetermined period after a signal has been sent.
