Gold Medal (Gold Medal with Congratulations of the Jury)

Team members: Prof. YANG Shenghao and Prof. YEUNG Wai Ho Raymond, from the Institute of Network Coding

Project: BATS: Enabling the Nervous System of Smart Cities

BATS, a revolutionary network coding technology, has been adopted in the Hong Kong Government’s pilot deployment of smart lampposts that will commence in mid-2019. BATS can provide multi-hop wireless network connections for smart lampposts without laying optical fiber to every lamppost. Laying new optical fiber, even if feasible, will require much construction work and severely disturb traffic and pedestrians. On the other hand, BATS enjoys the advantages of a low operating cost and a higher level of network security and stability. It provides a city-friendly and economical solution for mass deployment of smart lampposts, and so it expedites the advent of smart cities and and improves people’s quality of life.

Team members: Prof. Philip Wai Yan CHIU, from the Department of Surgery, Faculty of Medicine, Prof. Yeung YAM and Dr. Ka Chun LAU, from the Department of Mechanical and Automation Engineering, Faculty of Engineering

Project: Endoscopic Surgical Robot

This is a fully flexible endoscopic surgical robotic system for Endoscopic Submucosal Dissection of tumor and early cancer in the stomach and colon. The two flexible robotic arms can overcome limitations from the lack of maneuverability of the current tool (such as the size and strength of the arms) and perform challenging procedures to increase the safety and efficiency of surgery. The project enabled the performance of endoscopic surgery without incision and reduced pain and discomfort after surgery, leading to faster recovery of the patient. Multiple times pre-clinical trials showed that this invention reduces operation time by two thirds and it did not cause any perforation in any trials.

Project: 3D-printed soft robotic hand

Stroke, the leading cause of disability, has drawn more attention in view of the aging population. A personalised multi-functional soft robotic hand has been developed for daily recovery training purposes, allowing patients to reintegrate into society after the training. The feature of the soft robotic hand is the patented design of the Soft-Elastic Composite Actuator (SECA) which assists stroke patients in performing effective finger flexion and extension. Compared with the conventional metallic robotic hand, the soft robotic hand can assist patients in performing more hand function tasks to aid their daily lives; for example, gripping a pen and wringing a towel.

Project: Robotic Exoskeleton for Motion Assistance

 The project was developed to help paralysed patients stand up and walk. Hip and knee joints were equipped with powerful actuators. A magneto-rheological (MR) series elastic actuator was designed for the exoskeleton which can generate large controllable braking torque while consuming little energy. A lightweight “cable-spring” mechanism was utilised to solve foot-drop problem, which can improve the safety level for the user. Novel MR actuators can improve energy efficiency by 53%, and extend the working time of batteries by up to 112%. The system of exoskeleton and crutches is equipped with multiple sensors, combined with an intelligent controller, to provide safe and effective motion assistance to the user.

Project: An Intelligent Robot System for Adaptive tuning of 5G Microwave Filters

With the fast pace of mobile communication system development, the quantity for microwave filters is increased unprecedentedly. The complicated and slow manual tuning process as well as the shortage of experienced filter tuning technicians are two major obstacles that lead to low production capacity. This invention, which employs the analytic circuit model extraction theory originally developed in CUHK and the adaptive optimisers, can automatically tune filters with the speed that is multiple fold faster than manual tuning process. Additionally, the system provides a one-stop solution for big data analytics and quality inspection in the filter tuning process. Its unique capability in compensating for the hysteresis effect in tightening filter tuning screws allows the system to meet various challenging specifications. Another unique feature is its ability to diagnose the defects in the assembling process of production and to provide remedy instructions. The system has been used in the production lines for 5G base stations in a large scale.  

Team members: Prof. Tien-Tsin WONG and Dr. Wuyao SHEN, from the Department of Computer Science and Engineering, Faculty of Engineering

Project:  Binocular Single Vision on Entertainment and Medical Applications

Human eyes are capable of fusing two displaced images, even those with differences in details, contrast and luminance, up to a certain limit. This phenomenon is binocular single vision, based on which the team developed the world’s first Binocular Video Tone Mapping (BVTM) framework. Additionally, an AI-based self-learning mechanism has been invented and embedded within the framework, performing critical functions including automatic parameter adjustment and outcome optimisation. As for applications, the  BVTM framework can be adopted in the Hollywood 3D film-making industry by generating videos whose quality, vividness, realism and other attributes are beyond what is currently possible. In ophthalmologic examinations, the technology can be applied to Amblyopia (Lazy Eye) treatment.
