Hybridised Photocatalysis-Electrolysis Hydrogen Generation System
In conventional electrolysis, water molecules first dissociate into intermediate ions, namely, negative hydroxyl ions (OH-), positive hydrogen ions (H+) and positive hydronium ions (H3O+), before further decomposition into oxygen and hydrogen. This process of generating hydrogen is inefficient due to the high probability of hydroxyl ions recombining with either hydrogen ions or hydronium ions to form back water molecules. The technology described herein is related to a hybridised process which enhances hydrogen production rate of a conventional electrolysis system through combining the hybridised process with photocatalytic decomposition reaction. By combining the hybridised process with photo-catalytic decomposition, the probability of intermediate radical/ion recombination is reduced. This results in an increase in hydrogen and oxygen production of up to 25%. A prototype has been developed to demonstrate the feasibility and effectiveness of producing hydrogen and oxygen based on the hybrid photocatalyst-electrolysis method. With a strong knowledge in optimisation of the operating parameters in a hybrid photocatalyst-electrolysis reaction, the technology owner would like to seek partnership from the industry to commercialise the technology.   
Integrated Sensor Gateway for Digitisation ( ISGD)
Current IoT Gateways in the market are industry/sector specific and do not have the ready-to-use built-in functions that can be easily adaptable/customised for quick deployment turnaround time. The ISGD has all the ready-to-use built in functions to link up network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity, which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems. The ISGD is a versatile platform intended to be used in any IoT and many other applications. It provides most IoT and other common functions in industry. Users can ‘pick and choose’ the functions and deploy them quickly. Furthermore, it is highly flexible and expandable to many other functions. One example of ISGD application is in the medical and healthcare sector for monitoring the health and general well-being of senior citizens to ensure proper treatment is being administered. Other consumer devices to encourage healthy living, such as, connected scales or wearable heart monitors, are also a possibility with the ISGD.
Remote Data Acquisition for Failure Analysis
Monitoring and improving product reliability is a main concern in multi-stage manufacturing processes. The reduction of human labour in manufacturing plants coupled with shorter time to market is putting much pressure on some of the manual and tedious processes to generate timely and accurate test data. Specifically, for reliability testing, there is a need to subject the Device Under Test (DUT) to repetitive stresses over long periods of time. The unforeseeable change of material characteristics at different test stages or even pre-matured failures makes human monitoring and intervention a requirement. This repetitive nature of testing makes on-site human supervision ad nauseam. As a result, inaccurate data are often collected leading to skewed conclusions made in failure analyses. In view of the situation, there is a need for reliability testing process to take on a new approach in terms of monitoring and intervention. The Integrated Sensor Gateway for Digitisation (ISGD), coupled with a variety of customizable sensors and actuators, brings the advantages of Industry 4.0 manufacturing techniques to an industry application like product reliability testing. The ISGD, is versatile and utilizes various wired or wireless protocols for easy integration to existing industrial equipment. Detailed monitoring and data collection is also possible with the high performance micro-processors supporting the numerous sensors and actuators integrated. Now through a real-time contextualized dashboard, users of ISGD can gain minute control over the test system. Together with an optional Analytics platform, new trends of product behaviour can be discovered on top of regular test objectives.
Secured IoT Gateways
Security is a major hindrance for wide scale adoption of IoT. Constant sharing of information between devices and users could occur without the consent of related and authorized personnel. In addition, there is a lack of a security platform that provides access control and personalized security policies based on users’ needs and context, across different types of IoT ‘things’ and smart mobile devices. The availability of such security platform in the market will enable developers and service providers to develop and offer innovative end-to-end secured IoT services that able to meet various security and privacy needs for their customers in various industry verticals. The technology offer presents a patented solution that enhances the security of the wireless systems and devices by grouping security parameters required by the respective wireless network and from multiple layers (application/network/system) and re-sequencing them to generate a unique security key management scheme. This provides the flexibility for a user to choose or define his/her own combination of the security parameters using information from the applications, network, and systems levels, then sequence and synchronise these parameters in a manner he/she prefers to form a security key. Three collaborative cross-layer secure IoT gateways have been successfully developed targeting at advanced manufacturing, smart home, and outdoor environmental monitoring applications.
Hydrogen-on-Demand (HOD) System for Fuel Cell Portable Power Applications
The lack of hydrogen infrastructure has been the major barrier to fuel cell commercialisation, especially for portable applications. Some companies offer hydrogen solutions based on liquid sodium borohydride. These commercial solutions, however, have some drawbacks. Sodium borohydride solution faces problems, such as, precious catalyst with short lifespan, leakage, orientation issues, complex maintenance and impurities in the hydrogen generated. The impurities in hydrogen would accumulate in the anode chamber of a polymer electrolyte membrane fuel cell (PEMFC) and deactivate the electro-catalysis of hydrogen oxidation reactions, resulting in system breakdown. The limitations of these commercial products highlighted the need for a hydrogen-on-demand system that satisfies the U.S department of energy's (DOE) standards in terms of system weight, volume, cost and efficiency. The hydrogen-on-demand (HOD) system developed by the technology provider, has the attributes of ease of control, good handling safety, full hydrolysis of NaBH4, low cost catalyst with durable lifespan and high energy density. The HOD system could possibly unify the PEMFC applications by offering common hydrogen platform, and thereby increasing the customers’ flexibility in choosing different products without getting tied to proprietary hydrogen solution. This would help to penetrate and grow the consumer electronics and lifestyle market that is currently dominated by batteries.
Closed-Loop Automatic Frequency Control of Wireless Power Transfer
This technology has been developed in response to the state-of-the-art wireless power transfer systems, especially, in response to a need that has not been fully solved by current wireless power transfer systems. Magnetic resonance coupling is used to extend the effective charging range of inductive coupling from only a few millimeters to several centimeters, or even several feet. However, the sensitivity to operating frequency becomes highly pronounced with resonant coupling, and a theoretical optimum efficiency can only be achieved at one fixed antenna distance called critical coupling. At closer spacings, the efficiency will drop significantly due to a shift in the resonance frequency from over-coupling. Foreign conductive object proximity will also shift the resonance frequency and lower the efficiency. Accordingly, this technology was developed to track the resonance frequency and maintain high overall efficiency in the event of any shift in resonance frequency.
Tri-State Electrochromic Device - Modulation between Transparent, Color and Mirror
Our technology features a three state optical modulation between transparent, color and mirror appearance of a given surface, primarily on glass substrates. The switching between the three states can be triggered by a small voltage application. The versatile electrochromic device allows user to enjoy outdoor view in transparent state, blocking of sunlight in colored state and reflective finish in mirror state. It can offer additional light management capability compared to the solid state electrochromics. This technology is promising for the optical modulation of building façade and fenestration, in reducing energy consumption for in-door air conditioning, creating interactive visual displays on glass or façade decoration for interior designers to create space and light interaction.
