Title: Keisuke Oda: Innovator in Noise Detection Technology

Introduction

Keisuke Oda is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of noise detection technology, holding a total of 5 patents. His work focuses on developing innovative methods and devices that enhance noise detection and reduction.

Latest Patents

Oda's latest patents include a noise detection device, noise detection method, and noise detection program. The noise detection device features a frame signal generator that creates a frame signal with a predetermined first time length from an input signal. Additionally, a reference signal generator produces a reference signal from a signal that is located further back in time than the position of the frame signal in the input signal. A correlation value calculator is employed to compute a correlation value between the frame signal and the reference signal within a specified phase shift range. Furthermore, a periodic noise determiner assesses whether the frame signal contains periodic noise and calculates the period of that noise if present. The correlation value calculation range generator then establishes the range of the predetermined phase shift amount based on the periodic noise's period.

Another notable patent is the noise reduction device, noise reduction method, and noise reduction program. This invention includes a frame generator that frames an input signal to produce a frame signal. A reference signal storage unit retains a reference signal that indicates a periodic noise signal. The correlation value calculator again calculates a correlation value between the frame signal and the reference signal. A correlation candidate position decider identifies multiple correlation candidate positions that serve as potential matches for the signal portion of the reference signal correlated with the frame signal. The noise reduction processor reduces the periodic noise signal present in the frame signal by utilizing each signal portion from the correlation candidate positions, generating several candidate output signals. Finally, an output signal decider selects the candidate output signal that exhibits the greatest reduction of the periodic noise signal among the options available.
