Directly mounted sol-gel composite piezoelectric devices by spray coating technique for high temperature ultrasonic transducers

Autor: Mako NAKAMURA, Kei NAKATSUMA, Makoto KUMON, Makiko KOBAYASHI

Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 17, Iss 4, Pp JAMDSM0048-JAMDSM0048 (2023)

In this paper, we propose a fabrication method of a high temperature-resistant ultrasonic transducer for non-destructive tests. In typical pipe non-destructive wall thickness measurements, couplant material and backing material which do not have heat

Object Surface Recognition Based on Standing Waves in Acoustic Signals

Autor: Makoto Kumon, Rikuto Fukunaga, Tomoya Manabe, Kei Nakatsuma

Publikováno v: Frontiers in Robotics and AI, Vol 9 (2022)

This paper proposes the use of the standing waves created by the interference between transmitted and reflected acoustic signals to recognize the size and the shape of a target object. This study shows that the profile of the distance spectrum genera

Estimation of a Human-Maneuvered Target Incorporating Human Intention

Autor: Yongming Qin, Makoto Kumon, Tomonari Furukawa

Publikováno v: Sensors, Vol 21, Iss 16, p 5316 (2021)

This paper presents a new approach for estimating the motion state of a target that is maneuvered by an unknown human from observations. To improve the estimation accuracy, the proposed approach associates the recurring motion behaviors with human in

Binaural Localization for a Mobile Sound Source

Autor: Makoto KUMON, Shuji UOZUMI

Publikováno v: Journal of Biomechanical Science and Engineering, Vol 6, Iss 1, Pp 26-39 (2011)

This paper proposes a biologically inspired binaural auditory system to localize a mobile sound source. The robot considered in this paper has two microphones installed on a mobile platform to provide binaural hearing. An extended Kalman filter (EKF)

Stereo Sound Field Controller Design Using Partial Model Matching on the Frequency Domain

Autor: Makoto KUMON, Katsuhiro MIIKE, Kazuki EGUCHI, Ikuro MIZUMOTO, Zenta IWAI

Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 1, Iss 1, Pp 170-180 (2007)

The objective of sound field control is to make the acoustic characteristics of a listening room close to those of the desired system. Conventional methods apply feedforward controllers, such as digital filters, to achieve this objective. However, fe

Design of UAV-Embedded Microphone Array System for Sound Source Localization in Outdoor Environments

Autor: Kotaro Hoshiba, Kai Washizaki, Mizuho Wakabayashi, Takahiro Ishiki, Makoto Kumon, Yoshiaki Bando, Daniel Gabriel, Kazuhiro Nakadai, Hiroshi G. Okuno

Publikováno v: Sensors, Vol 17, Iss 11, p 2535 (2017)

In search and rescue activities, unmanned aerial vehicles (UAV) should exploit sound information to compensate for poor visual information. This paper describes the design and implementation of a UAV-embedded microphone array system for sound source
