Title: The Innovations of Tomohiro Ueno
Introduction
Tomohiro Ueno is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of communication technology, holding a total of 12 patents. His work focuses on enhancing communication apparatuses and methods, showcasing his expertise in the industry.
Latest Patents
Ueno's latest patents include a communication apparatus and communication method. In this invention, a first node and a second node transmit packets to a third node via a switch. The packets are buffered in a Tx buffer within the switch before being transmitted to the third node. When the third node detects signs of congestion at the Tx buffer based on the reception frequency of the packets, it recognizes the transmitting nodes from the addresses included in the received packets. Consequently, a control packet for a transmission stop request is sent to both the first and second nodes. Upon receiving this control packet, the first node ceases transmission of packets addressed to the third node, while the second node does the same.
Another notable patent is a transmission apparatus and transmission method. This invention features a network-side interface unit that receives a signal transmission frame containing a client signal from both a working line and a protection line of a network. It extracts the client signal from the received frame and transmits it to a client transmission path using a generated clock, based on frequency adjustment information included in the signal transmission frame. Additionally, a protection-line-side memory stores the frequency adjustment information, and a switch controller generates a clock using this information when the signal transmission frame fails to be received from the working line.
