Title: The Innovative Contributions of Zoe S. Quan

Introduction

Zoe S. Quan is a prominent inventor based in Chicago, IL, known for her significant contributions to the field of data communication. With a total of 2 patents, she has developed innovative technologies that enhance the efficiency and speed of communication systems.

Latest Patents

Among her latest patents is a groundbreaking method and apparatus for data communication that utilizes multiple physical data links. This multi-link interprocessor communication protocol allows processors to increase their communication speed by leveraging multiple physical links in parallel. When a message is transmitted, it is divided into smaller segments and distributed across the available links based on a straightforward algorithm. The packets are then received, verified for accurate transmission, and reassembled in the correct order. This method allows for efficient handling of packets, even if they arrive out of order, ensuring that communication remains seamless and reliable.

Another notable patent focuses on controlling multi-port hunt groups in a distributed control switching system. This system efficiently manages idle group members by sequentially searching through switching modules until an available member is found. The busy/idle hunt data is maintained within each module, eliminating the need for inter-module communication to update hunt data, thus streamlining the process.
