Project Title: Realization of a Novel Automatic 2D to 3D Autostereoscopic Images for Multiple Operating System Computing Devices

Abstract

The 2D to 3D autostereoscopic image conversion technology is based on an invention by the applicant which has been previously filed as a PCT patent. The invention enables a single picture (which may be captured by an ordinary webcam or digital camera) or screen shots of the computer to be converted into a set of multi-view images. The latter can be displayed on a 3D monitor (or digital photo frame) and provide viewers with a 3D perception without the need of wearing special glasses. The method can also be used to convert motion video signals.

The objective of this project is to develop a set of software libraries for realizing the technology on computers that run on different Operating Systems. The target Operating Systems (OS) include the popular PC, MAC, and the Android. It is known that different Operating Systems differ significantly in programming language, environments (SDK), as well as input and graphic interfaces. Hence different methods of realization are required for the same method. A set of drivers will also be developed to display the converted 3D content to different kinds of 3D autostereoscopic monitors and photoframes.

The software libraries and drivers can be licensed to other developers, who can produce their own products by wrapping cosmetic features and user interfaces.

Project Title: LED Replacement Lamp Driver with Universal Compatibility

Abstract

An LED replacement lamp driving technology with universal compatibility is proposed.The distinct feature of this technology is that it is operable by different power sources, including conventional electromagnetic ballasts, high-performance electronic ballasts, and ac mains.The nominal operating frequency of the electromagnetic ballast and ac mains is low, either 50Hz or 60Hz.The one of the electronic ballasts is much higher, ranging from 40kHz to 80kHz. The proposed LED replacement lamp is able to operate at a wide range of operating frequencies and voltage levels.When the lamp is connected to an electromagnetic ballast or ac mains, its input current has high input power factor and low total harmonic distortion.When it is connected to an electronic ballast, it will simulate the input characteristics of a gas discharge lamp and take sinusoidal input current. Hence, existing fluorescent lamps can be replaced readily by the proposed LED replacement lamps, irrespective of the type of the ballast used. This concept is truly environmentally-friendly, as the lighting network can be converted from fluorescent into LED without modifying the light network or infrastructure. In addition, as the lamp can be operated from the AC mains, like an ordinary light bulb, the lamp can still be used even if the electromagnetic or electronic ballast connected to it is malfunctioned.The proposed technology is applicable for new installation or retrofit market.For the new installation, the LED lamp can be powered from the AC mains without requiring any external ballast. For the retrofit market, existing fluorescent lamps can be replaced by the LED lamps without modifying the lighting infrastructure. Finally, the technology is generic as it can be applied to different lamp types, like the compact fluorescent lamps.

Project Title: Bias-free Magnetoresistive Sensors

Abstract

Information technology industry has identified smart systems as the new technological revolution. Sensors are the key components of such systems. From vehicles to smartphones, every modern system is packed with sensors. Besides, smart sensors and systems are believed to be the best hope for dealing with the growing environmental problems.

In smart systems, sensors play an important role because they form the link between mechanical and electronic systems. Magnetic sensors are widely used to measure mechanical quantities because they allow contact-less and, therefore, wear-free measurements. In particular, magneto-resistive sensors can be easily integrated with the semiconductor technology.

The goal of this project is to develop novel magneto-resistive sensors with better performance as compared to those currently employed in the industry. The sensors we propose here are still solid-state magnetoresistive devices but the magnetic configuration is different from the currently used spin-valve. This helps overcome the two major limitations of the current magneto-resistive sensors: reliability at high temperatures and necessity of a bias magnet.

The materials and fabrication techniques to be used are low cost and compatible with the current industry technologies, with the aim to pursue integration of these new sensors with the semiconductor electronics and fast commercialization. The magnetic materials used, will be restricted to standard ferromagnetic metals to be grown on silicon substrates.

Project Title: Development of a Rapid-identification Kit for Meat Ingredients in Processed Food

Abstract

Hong Kong is a megalopolis with limited land area. Hundreds of tonnes of foods are imported from peripheral regions every year. To make the transportation more convenient and to keep the nutrient values of the food, processed and frozen or chilled methods are usually adopted. However, it is difficult to identify their meat ingredients by just observing the selling appearances, such as morphological features in trimmed fish or the packed sausages and dumplings. Moreover, accidental or intentional mislabelling will mislead the consumers. Manufacturers and retailers can increase their profit margin through substitution of low value species. Serious consequences may be resulted if one has allergies or religious restriction in diet. It is worthy for us to develop a fast and simple identification method or tool, providing an efficient monitoring system to prevent such possibilities.

DNA barcoding is a molecular method developed over the past few years to identify the sample species. The FDA of U.S. has accepted the barcoding gene to identify fish samples. The same barcode has also been proven to be effective on mammalian species. However, the current barcode identification procedure, depending on the sample size, requires 2-3 days for results. Based on the current knowledge of DNA barcoding and molecular biology, we will develop a rapid, cost-effective and species-specific identification kit which can identify ingredients in processed food. Particularly, this array-form platform allows detection of mixed species samples in a single identification experiment, hence saving the time and cost for multiple identification procedures of different species.

Project Title: Zigbee Advanced Metering Infrastructure and Energy Management - Backend Design

Abstract

Advanced Metering infrastructure (AMI) is a solution for automatic meter data collection, energy auditing and energy management. ZigBee is a commonly adopted wireless protocols adopted by many utilities and companies in the world for energy applications. The transmitted data will then be presented at the server platform for the utility. The advantage of this platform allows data (of different formats) from different front-end AMI systems to be collected and viewed at the same time. Hence, the utility may then consider the energy distribution based on the collected data. Such a platform also facilitates demand response applications for households so that users at home may perform energy management e.g. tuning the temperature of air-conditioners or heaters, dimming of lighting systems etc. This project aims to develop a nature server platform based on ZigBee for various kinds of front-end AMI and energy management systems. This platform will be one of the key elements for smart grid development.
