Latest Patents

Fumio Hashimoto holds a patent for an "Estimated train occupancy range determination device, onboard system, and estimated train occupancy range determination method." This onboard system measures the train's position by assessing the rotational speed of a tacho-generator. It determines an estimated train occupancy range, indicating where the train may be present, and transmits this information to a ground system. The onboard system also corrects the train's position based on communication results with a correction coil when the train passes through the installation point of the coil. If the train's position shifts backward due to this correction, the system continues to determine and transmit the estimated occupancy range based on the train's position before the correction until the latest position is reached.
