Title: Innovations by Koichi Hata: A Leader in Packet Compression Technologies

Introduction

Koichi Hata, an esteemed inventor from Katano, Japan, has made significant contributions to the field of packet compression technology. With a portfolio boasting 20 patents, Hata is renowned for his innovative methods and systems that enhance data transmission efficiency. His work has had a profound impact on the industry, particularly through the optimization of header compression and decompression.

Latest Patents

Among Koichi Hata's latest patents are two notable inventions focused on improving packet handling:

1. **Method and Apparatus for Header Compression**: This invention introduces a packet compressor that operates under two modes—reliable and optimistic. A mode determination unit plays a critical role in this system by counting the number of ACK (acknowledgment) and NACK (negative acknowledgment) packets received within a specified timeframe. If the count of NACK packets exceeds a predefined threshold, the system shifts to the reliable mode. Conversely, if the ACK packets surpass a certain count, it defaults to the optimistic mode, enhancing packet efficiency.

2. **Apparatus and Method for Header Decompression**: This patent describes a header decompression apparatus that utilizes reference information to decode compressed packet headers. The system includes an error detector to identify CRC errors in packets post-decompression, ensuring that only correct packets are output. A successive error counter and decompression success counter facilitate better management of reference information, enabling the system to request updates when necessary, based on error states.
