Title: Koji Okazaki: Innovator in Vector Quantization and Synchronism Establishment

Introduction

Koji Okazaki, an accomplished inventor based in Kawasaki, Japan, has made significant contributions to the fields of vector quantization and synchronism establishment. With a total of six patents to his name, Okazaki's work demonstrates innovative solutions that enhance both technology and communication systems.

Latest Patents

One of Okazaki's latest inventions is a vector-quantizing device having a capability of adaptive updating. This device features a first code book that stores multiple code vectors at specific addresses, alongside a first addressing unit that selects these code vectors. It includes a synthesis unit that generates a synthetic signal simulating the input signal, and an evaluation unit that assesses the difference between the input and synthetic signals to find a code vector that minimizes this difference. The device also incorporates a second code book for storing additional code vectors and an update unit that counts the frequency of code vector selections.

Another recent patent is the synchronism establishing method and apparatus, which features multiple modules with different synchronization patterns. The innovation enables seamless switching between synchronization states, reducing the transition time to such an extent that it can be disregarded, while still providing advantages similar to traditional synchronism systems. A master module communicates the establishment of synchronism to a slave module, which then enters a waiting mode, thus allowing for efficient processing operations without unnecessary disruptions.
