Latest Patents

One of his latest patents is a "Cross-connection network using time switch." This invention involves an internal frame signal producing circuit designed for cross-connecting first bit rate signals. These signals are produced by multiplexing second bit rate signals, with the first bit rate being higher than the second. The internal frame frequency is predetermined to be higher than the nominal frequency of the first bit rate digital signals. The process includes stuff-synchronization of m second bit rate signals to create an internal frame signal. Another notable patent is also titled "Cross-connection network using time switch." This invention allows multiple asynchronous input digital signals to be cross-connected to various output lines using a time switch. The input digital signals are pulse stuffed at a common higher bit rate and synchronized by attaching extra bits. The signals are then assigned into serial frames and interchanged in a time division manner.
