Latest Patents

One of Shinada's latest patents is the "ATM cell policing method and apparatus." This invention focuses on an input cell policing method in a network of asynchronous transfer mode. According to information contained in a header field of each input cell, a group to which the cell belongs is identified. For each group, a plurality of time frames with predetermined lengths and mutually different phases are set to count the number of input cells in each time frame period. The count value of input cells is compared with a predetermined threshold value. An input cell exceeding the threshold value in any time frame is considered an excess cell, which can either be discarded or marked for violation.

Another notable patent is the "Trouble diagnosis system of UPC circuit." This system is designed for diagnosing failures in a UPC circuit by controlling cell traffic volume based on prescribed information about cell traffic. The diagnosis is achieved through usage parameter determination of at least one kind of cell, using multiple systems and comparing the results. The system includes an operating UPC circuit for controlling various kinds of cells and a standby UPC circuit for additional control. Fault diagnosis of the bridge memories is conducted by comparing their contents using multiple systems.
