Title: Tetsuya Wakui: Innovator in Noise Reduction Technology
Introduction
Tetsuya Wakui is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of electronic devices, particularly in noise reduction technologies. With a total of 15 patents to his name, Wakui's innovations have had a substantial impact on the industry.
Latest Patents
Wakui's latest patents include an electronic device and its control method. This invention focuses on removing mechanical noise from a pre-identified device while tracing changes in gain of acoustic wave data. The method involves automatically adjusting the gain of a signal from a microphone using an Auto Level Control unit (ALC). A threshold based on the ALC's gain is stored in a register, and a comparator generates weighting coefficients to output to multipliers. This process allows for the calculation of a weighted average value of data, effectively storing only the noise component in memory. The level adjusting unit then modifies the data read from memory according to the current gain, resulting in noise-free output.
Another notable patent is related to a video camera apparatus and its control method. This invention addresses noise generated by components like a rotary drum in recording/playback devices. By extracting and reducing noise waveforms, the technology enhances audio quality. The control microcomputer calculates the average of in-phase data during mechanical noise generation cycles, storing the results in memory. This allows for the subtraction of noise components from current input data, ensuring clearer audio output.
