Latest Patents

Hirono holds a patent for a digital transmission network. This network comprises a plurality of transmission terminals and receiving terminals, all interconnected by a transmission line of either metal cable or optical fiber cable in a loop configuration. Signals are transmitted using time-share multiplexing in one direction. Each transmission terminal is allocated an individual time slot through time-sharing multiplexing for all transmitted signals. A timing device is integrated into the loop to ensure that the delay time is corrected to match the delay time of one frame, which includes delays caused by the transmission line and cable. The design allows for continuous consecutive frames. The transmission line can be configured as either a single or dual loop. In the case of a single loop, a bypass circuit is included to bypass a signal input to the transmission line if necessary. For a dual loop configuration, which includes optical fiber cables for both working and backup lines, a control signal is transmitted from a central receiving terminal to all receiving terminals. This signal enables the input of signals from the backup line and subsequently returns the receiving terminals to a state that allows input from the working line, confirming normal operation in proximity to the central unit.
