Title: Innovations by Nai-Chia Chang
Introduction
Nai-Chia Chang is a notable inventor based in Sinying, Taiwan. He has made significant contributions to the field of sound localization and collision detection technologies. With a total of two patents to his name, his work showcases innovative approaches to solving complex problems in robotics and sound engineering.
Latest Patents
Nai-Chia Chang's latest patents include a sound source localization system and method. This system comprises sound capturing devices and an arithmetic unit. The sound capturing devices are designed to sense a sound source and output time domain signals. The arithmetic unit then transforms these time domain signals into frequency domain signals. It performs a cross spectrum process based on the frequency domain signals to determine time differences of arrival, ultimately locating the sound source based on these time differences and the positions of the sound capturing devices.
Another significant patent is a collision detection apparatus, which includes a main body, at least one air bag located at the periphery of the main body, and at least one baro sensor. The air bags are interconnected, and the baro sensor detects pressure variations at different time points. This apparatus is capable of judging whether a collision has occurred and measuring the collision force through the baro sensors. It determines the time of collision occurrence and the collision position based on the pressures of the air bags at various time points.
