Title: The Innovations of Takeshi Yoshimura

Introduction

Takeshi Yoshimura is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of character recognition and acoustic signal transmission. With a total of 10 patents to his name, Yoshimura's work has had a lasting impact on technology.

Latest Patents

Yoshimura's latest patents include a character recognition device, method, system, and program. This character recognition device features an image input unit that receives an image, a character region detection unit that identifies character regions, and a character region separation unit that separates these regions on a character-by-character basis. The character recognition unit performs recognition on the separated characters and outputs one or more recognition result candidates. Additionally, the device includes a first character string transition data creation unit that calculates weights for transitions to the candidates and creates transition data. The WFST processing unit then performs state transitions based on this data, accumulating weights and calculating cumulative weights for each transition.

Another notable patent involves a modulation device, demodulation device, and an acoustic signal transmission method. This system allows for synchronization of data signals without using a carrier frequency for the synchronization signal. The modulation device transmits an acoustic signal superposed with a PN sequence, while the demodulation device determines the PN sequence with the highest correlation value to detect synchronization points and demodulate the data signal.
