Title: Shotaro Ueno: Innovator in Noise Reduction Technology
Introduction
Shotaro Ueno is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of noise reduction technology, holding 2 patents that showcase his innovative approach to solving sound-related challenges.
Latest Patents
Ueno's latest patents include a noise reduction device and a mobile body device, along with a noise reduction method. The first patent describes a noise reduction device that incorporates a second corrector. This corrector generates a correction signal by adjusting an output signal or a standard signal using a predetermined parameter. The generated correction signal is then added to an error signal, resulting in a corrected error signal that closely approximates the error signal indicating residual sound at a sound reception location.
His second patent focuses on an active-noise-reduction device and system, which also includes a mobile device and an active-noise-reduction method. This invention features a reference signal generating unit that outputs a referencing signal correlated with vibration to an adaptive filter unit. The filter coefficient update unit receives an error signal input and continuously updates the filter coefficient of the adaptive filter unit. The detection unit monitors the filter coefficient and determines the output size of the adaptive filter unit. Consequently, the amplitude of the cancelling sound is adjusted based on the estimated output size.
