Title: Takahiro Tsuboi: Sound Processing and Ultrasonic System Patents

Introduction

Takahiro Tsuboi is an inventor associated with Kyoto, Japan. His work includes inventions in sound-signal processing and ultrasonic systems. The supplied information lists 3 patents and identifies Rohm GmbH as his company.

Latest Patents

**Signal Processing Device, Sonic System and Vehicle.** This invention describes a device that generates a sound-wave transmission signal and outputs a received signal based on incoming sound waves. Its reflected-wave detection unit identifies a possible reflection by monitoring an envelope-detection signal during the transmitted wave’s reverberation period and detecting when that signal falls below a threshold.

**Sound Wave Processing Device and Ultrasonic System.** This invention uses a burst drive signal with sensor-drive periods and intervals between them. The first drive signal operates within the band-pass filter’s frequency range, while the second uses a frequency outside that range and different from the sensor element’s resonant frequency.

Career Highlights

The listed patents reflect Tsuboi’s work on processing transmitted and received sound signals, detecting reflected waves, and controlling ultrasonic sensor drive signals. These approaches address signal behavior during reverberation and the coordination of drive frequencies in ultrasonic systems.

Collaborations

The supplied information names Shogo Takamura and Hideki Matsubara as Tsuboi’s coworkers. It does not specify their roles in the listed inventions or patent applications.

Conclusion

Takahiro Tsuboi’s listed inventions focus on sound and ultrasonic signal processing, including reflected-wave detection and sensor-drive control.
