Title: Makoto Kumada: Innovator in Communication Technology
Introduction
Makoto Kumada is a notable inventor based in Fukushima, Japan. He has made significant contributions to the field of communication technology, holding a total of 2 patents. His work focuses on enhancing communication systems through innovative methods and materials.
Latest Patents
Kumada's latest patents include a "Method for DTMF transfer by RTP." This method facilitates DTMF transmission between different address systems in a communication system. It involves a first network containing an SIP terminal connected to an SIP server and a second network with a similar setup. The SIP converter plays a crucial role in detecting coded DTMF information and determining compatibility with the other network. If the other network does not support the coded DTMF information, the SIP converter stores the corresponding voice-data DTMF into a payload of RTP for transfer.
Another significant patent is for a "Photo and radiation-sensitive organopolymeric material." This material features at least one Si--Si bond and demonstrates excellent resistance to dry etching, good adhesion, and heat resistance. It is particularly useful for finer patterning with high resolution.
