Latest Patents
One of his latest inventions is a power line communication system. This system enables high-quality communication by utilizing a pair of power lines connected to a vehicle-mounted battery. It features a pair of communication lines that connect to the power lines, allowing for the transmission of high-frequency signals of 1 MHz or more. The system includes a balance filter interposed between each communication line and the vehicle-mounted communication apparatus, ensuring effective signal processing. Additionally, it incorporates electrically balanced lines connected between the balance filter and each communication apparatus, which are power-fed from the battery to facilitate communication.
Another significant patent is a spread spectrum transmission system. This system is designed to prevent external noise infiltration and leakage of spread spectrum signals. It achieves this by separating electrical power for load devices from that used for communication. The system includes a plug socket for terminal connection, which receives a plug for connecting a spread spectrum communication terminal apparatus. A blocking filter is used to prevent electrical noise from entering the terminal apparatus and to stop spread spectrum signals from passing in the reverse direction. The design allows for the use of an inexpensive, low-capacity blocking filter, making it a cost-effective solution.
