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.
A Novel Graph Optimization Approach to Localization (GOAL) for Unmanned Systems
GOAL is concerned with 2-D plane and 3-D space localization technology for robots. The methodology leverages on ultra-wideband (UWB) aided localization system and can be extended to application with other sensors such as inertial measurement unit (IMU), Wi-Fi, Optical Flow and Cameras. Unlike existing Filter-based localization algorithms which have unacceptable estimation error in altitude, this technology provides high accuracy in the estimation in altitude without adding other sensors for altitude estimation, which saves cost of localization system. Also, this technology has the function for rejecting Non-line-of-sight (NLOS) measurements, which enables this technology to NLOS environment. The design of flexible moving window in this technology decreases the computational resources and increases the robustness to short duration lost in signal, which enables this technology to be applied to robots with ultra-low power processor.
Non-iterative Simultaneous Localization and Mapping (NI-SLAM)
Non-iterative Simultaneous Localization and Mapping (NI-SLAM) is a patented method for position tracking and environment dense reconstruction, using affordable sensors such as depth camera and inertial sensors. Compared to traditional SLAM methods, the superior real-time processing speed of NI-SLAM is achieved by an innovative method of data registration that performs point-cloud matching in Fourier Domain.
On-demand Shared Transport and Route Optimization Systems
The company powers some of the most successful on-demand shared transport systems across the world. Its technology reinvents a fixed route bus into a dynamically routed system that continually redesigns itself based on real-time passenger demand. The algorithm works to ensure the highest patronage for buses, while providing a high-quality shared experience for passengers. The system is highly configurable to ensure it can adapt to different geographies, densities and also citizen behaviours around the globe.
Latchup Detection and Protection Technology for Space Applications
To advance intelligent satellites, a new Latchup-Detection-And-Protection (LDAP) Integrated Circuit (IC) is offered to enable the application of Commercially-Off-The-Shelf (COTS) ICs in satellites for the first time. State-of-the-art COTS ICs can latch up (Single Event Latchup) when a heavy particle strikes, resulting in permanent damage.  The new LDAP offers a novel unprecedented means to protect state-of-the-art COTS. The technology solution is supported by a full set of Radiation-Hardened-By-Design (RHBD) digital library cells whose attributes include ultra-low error-rate and yet low area-, power-, and delay-overheads when compared to the state-of-the-art solutions.  The RHBD library cells are space-grade, not only increasing the lifespan of the electronics in space environments, but also enabling unprecedented higher processing power (more intelligence) for electronics.
Highly Effective Thermal Management for Battery Systems
Environmental pollution concerns and high fuel cost is driving the car industry towards Electric Vehicle (EV). Li-ion cell is a common adopted energy source for EV. However, Li-ion cells required proper temperature control to function properly. A key factor that affects the battery is temperature. < 0°C:  difficult or impossible for charging >60°C:  difficult for discharging and risk of degradation, shortened service life >70°C ~ 90°C:  will trigger a self-heating reaction with internal cell faults with risk of thermal runaway, presenting safety hazards. Most Li-ion battery achieves their rated capacity at 20~25°C and their capacity will drop ~10% for every increase of 10°C. Regulating the battery temperature during continuous charge and discharge is a challenge, especially in temperate climates. Existing cooling solutions consist of the battery modules sitting on or attached to heat sinks that are in turn cooled by a coolant loop. The drawbacks are that the cooling efficiency is low, and the effectiveness is poor, since only a small part of each module receives the cooling effect. Besides, heat sinks are generally thick and heavy due to the coolant loop. The result is that temperatures will differ from module to module, cell to cell. Even within the same cell, different regions may have different temperatures. Battery packs used in EVs are constrained by space and weight, so cooling systems for the battery packs must be compact and lightweight, and yet meeting the cooling requirements. Our patent granted technology is able to carry coolant to each individual cell in a compact structure. This ensures consistency and uniformity of heat transfer from each cell in a battery pack, extending their lifespan and safety by allowing them to operate in their optimum temperature range (10 ~ 35°C), Charging and discharging can also take place in all ambient temperature.
