Latest Patents
One of Lim's latest patents is a power conditioning system and method. This system includes a grid blackout determiner, a voltage controller, and a processor that is electrically connected to both the grid blackout determiner and the voltage controller. The processor is designed to identify the state of a grid as either a blackout state or an unstable state based on the amplitude or frequency of the detected voltage. It controls the voltage controller to adjust the load voltage input to a command voltage and modifies the frequency of the detected voltage accordingly.
Another significant patent by Lim is a method for purifying carbon nanotubes (CNTs). This method involves heating CNTs that contain metallic impurities and metallic oxide impurities. It reduces the metallic oxide impurities by passing a reducing gas through the CNTs and removes the impurities by using a liquid halide with a carrier gas. This innovative approach allows for the effective and economical purification of CNTs in a single step, enhancing the overall purification effect.
