Title: George Fukutomi and an Interface Circuit for Lower-Power Data Transmission.

Introduction

George Fukutomi is an inventor associated with Tokyo, Japan, and Oki Semiconductor Co., Ltd. His listed patent concerns an interface circuit designed to reduce power consumption while supporting data transmission.

Latest Patents

Fukutomi is credited with 1 patent, titled “Interface circuit.” The invention uses a low-frequency clock signal generated by a CR oscillation circuit to remove noise from and detect the VBUS signal. A process control portion receives the resulting detection signal, while the detected signal also enables a quartz oscillation circuit when data transmission is designated. The quartz circuit then supplies a high-frequency clock to the transmission function portion. When transmission is not required, the enable signal is withheld from the quartz circuit. Because the CR oscillation circuit consumes relatively little power, this arrangement can reduce the interface’s overall power consumption.

Career Highlights

The available information associates Fukutomi’s patent work with Oki Semiconductor Co., Ltd. The interface circuit reflects an engineering approach that uses a low-power detection stage to activate a higher-frequency clock only when needed.

Collaborations

Fukutomi’s listed coworkers include Shinji Hiratsuka and Hirohisa Tanabe. The available details do not specify their roles in the patent or the extent of their collaboration.

Conclusion

George Fukutomi’s recorded invention focuses on reducing power use in data-transmission interfaces by controlling when a high-frequency clock operates.
