Title: Sei Matsumoto: Patents in Data Processing and Communications.

Introduction

Sei Matsumoto is an inventor associated with Yokohama, Japan. His work includes inventions in image-data processing and communication systems. The supplied information lists 2 patents and identifies Matsushita Graphic Communication Systems, Inc. as his company.

Latest Patents

One listed patent, “Data Processing Apparatus for Decoding, Converting in Size and Coding,” describes a system that stores line data in an input buffer and searches for specific codes. Its search control section adjusts the reference number used to trigger searches until it finds a code, after which the apparatus takes out the corresponding line data. This approach coordinates code detection with the amount of picture data held in the buffer.

Another listed patent, “Data Transmitting Apparatus and Method for Executing Both Facsimile,” concerns switching between facsimile and data communication modes. The apparatus sends a signal indicating that the called party is a non-voice terminal and checks for a signal indicating that the caller is also a non-voice terminal. If that signal is not detected, the system switches to data communication mode and continues monitoring, returning to facsimile mode when the signal is detected.

Career Highlights

Matsumoto’s listed inventions address practical challenges in processing picture data and managing communication between facsimile and data terminals. Both patents describe systems that use signal detection and control logic to determine how data should be handled.

Collaborations

Matsumoto is associated with Matsushita Graphic Communication Systems, Inc. His listed coworkers include Sakae Miyamoto and Zhi Jian Dai.

Conclusion

Sei Matsumoto’s two listed patents reflect contributions to data processing and communication technology, with particular attention to efficient code searching and automatic mode switching.
