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)
