Latest Patents

Hayashi's latest patents include innovative designs for cross-connection networks using time switches. One of his patents describes an internal frame signal producing circuit that operates within a cross-connection system. This system cross-connects first bit rate signals, which are generated by multiplexing second bit rate signals. The internal frame frequency is synchronized with the second nominal frequency of the second bit rate digital signals. The process involves stuff-synchronizing m second bit rate signals to produce a series of signals that are arranged to create an internal frame signal.

Another patent focuses on a cross-connection network that allows multiple asynchronous input digital signals to be cross-connected to various output lines using a time switch. The input signals are pulse stuffed at a higher bit rate and synchronized by adding extra bits. This method enables the interchange of signals in a time division manner, ensuring that the output signals are accurately reproduced.
