Latest Patents

Hidetoshi Homma's latest patents include a time synchronization system and method specifically designed for trains. This innovative system features an inter-vehicle network that connects monitoring and control devices with an intra-vehicle network. The design includes a train clock station at the highest level of a hierarchical structure, along with a vehicle clock station at a middle level. Additionally, a correction information waiting station is established at the lowest level. The train clock station is capable of performing time corrections based on reference time, while the vehicle clock station adjusts its time based on messages from the train clock station. The correction information waiting station also performs time corrections based on messages from the vehicle clock station.

Another significant patent by Homma is the train configuration recognition system and apparatus. This invention utilizes a pair of transmission lines within the train, where train end detection switches are connected at both ends of each carriage group. A resistor is inserted in one of the transmission lines, allowing a voltage detector to measure the voltage between the lines. The controlling unit manages the switches to ensure that power is supplied at only one location within the train, enabling the recognition of the train's configuration based on the measured voltages.
