Title: The Innovations of Miyuki Okamoto
Introduction
Miyuki Okamoto is a prominent inventor based in Hashima, Japan. She has made significant contributions to the field of error detection and correction circuits, holding a total of 6 patents. Her work has advanced the reliability of data transmission and processing.
Latest Patents
Among her latest patents is a method of detecting error locations and an error detection circuit, which includes an error correction circuit and a reproducing apparatus. This innovative error correction circuit is capable of detecting burst errors within a data signal reliably. It comprises a reading unit, a first estimation unit, a second estimation unit, and a correction unit. The reading unit reads the data signal, while the first estimation unit estimates error locations based on the BIS code included in the data signal. These locations are stored in an error location storing unit. The second estimation unit also estimates error locations based on the characteristics of bit strings adjoining the BIS code, storing these locations as well. The correction unit identifies erasure locations based on the stored error locations and performs erasure correction. This dual estimation approach ensures that burst errors are detected without fail.
Another notable patent involves a method and apparatus for subband coding, which allocates available frame bits based on changeable subband weights. This method generates weight data for each audio band and assigns a number of bits to each band according to this data. It calculates the total number of bits for one block and compares it with upper and lower limits of a compression target value. Based on this comparison, the method adjusts the weight data and reassigns the number of bits accordingly.
