Title: Koki Goto: Innovator in Power Line Communication Systems
Introduction
Koki Goto is a notable inventor based in Toyama, Japan. He has made significant contributions to the field of power line communication systems, holding a total of 2 patents. His innovative work focuses on enhancing communication quality through advanced technology.
Latest Patents
One of Goto's latest patents 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 connected 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. This filter is designed in a balanced configuration. Additionally, the communication system incorporates a pair of 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 by Goto is a single-phase 3-wire power line connection determination apparatus and method. This method determines whether multiple power outlets in a 3-wire power line connection are connected to the same outer wire. It involves identifying the hot terminal of a first power outlet and detecting the first zero cross time of the hot terminal to which AC voltage is applied. The process is repeated for a second power outlet, and it is determined that both outlets are connected to the same power line if the elapsed time from the first to the second zero cross time is an integral multiple of the AC voltage cycle.
