Title: Kiyoshi Sukegawa: Innovator in Transmission Line Monitoring and DSL Communication
Introduction
Kiyoshi Sukegawa is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of transmission line monitoring and digital subscriber line (DSL) communication. With a total of 5 patents to his name, Sukegawa continues to push the boundaries of technology.
Latest Patents
One of Sukegawa's latest patents is a transmission line monitoring method and apparatus. This innovative apparatus includes a first optical coupling unit, a first optical dividing unit, a second optical coupling unit, a second optical dividing unit, and a monitoring unit. The first optical coupling unit couples a down data signal with a first wavelength and an examination signal with a second wavelength into a first coupled signal. The first optical dividing unit receives this signal and divides it into the down data signal and the examination signal. The second optical coupling unit then couples an up data signal with the first wavelength and the examination signal into a second coupled signal, which is subsequently divided by the second optical dividing unit. The monitoring unit is responsible for monitoring faults and their positions.
Another significant patent is a DSL communication method and apparatus. This technology enables mutual communications between a user-site DSL modem and a provider-site router using existing two-wire telephone lines. The DSL modem correlates multiple virtual channel values to a PPP connection between the modem and the router. It receives input IP data and outputs it according to a defined priority class. An ATM cell is generated, assigning one of the virtual channel values to the output IP data, which is then transmitted to the router.
