Latest Patents

Yamashita's latest patents include a "Microphone array sound source location system with imaging overlay." This invention aims to accurately locate and display the source of sounds, such as noise in a factory setting, even in outdoor environments. The system utilizes pairs of microphones arranged along the X and Y axes to estimate the direction of the sound source based on differences in sound arrival times. Additionally, an image of the area surrounding the estimated sound source is captured by a camera and displayed on a personal computer.

Another significant patent is the "Vibration source probe system." This system is designed to detect surface waves of vibration traveling over the ground or floor of a building. It specifies and displays the location of vibration sources, whether at a factory or on a road. The position of the vibration source is estimated using phase differences or arrival time differences between vibrations detected by sensors placed at predetermined distances. Similar to his sound localization system, an image near the estimated vibration source is captured and displayed on a computer screen.
