Latest Patents

One of Junki Ema's latest patents is a communication system that forms a communication path in a loop using trunk lines and a redundant communication path. This system is designed for bus-type communication networks, such as CAN. The switch in this system remains normally off, and the backup line is disconnected during steady states. A disconnection detection unit is integrated at each joint connector to monitor connectivity. When a disconnection is detected, the switch closes to enable the use of the redundant path. Additionally, the routing map of a central gateway is automatically updated to prioritize the non-disconnected redundant path.

Another significant patent is his on-vehicle communication system. This system employs switching hubs, or relay devices, at various branch positions along a wire harness that includes a trunk line. Each relay device is equipped with a failure detection part, a routing map, and a path control part. The trunk line is designed to allow the selective use of multiple paths. When a failure is detected by any relay device, it instructs another relay device to change the path. The routing maps in the receiving relay device are then adjusted according to the failure location. Furthermore, a VLAN is constructed on an Ethernet communication network, with logical assignment controlled by a central gateway.
