Title: Innovations by Louis Seng Hong Pang
Introduction
Louis Seng Hong Pang is a notable inventor based in Singapore, SG. He has made significant contributions to the field of information handling systems, particularly in the area of disc drives. With a total of 5 patents to his name, his work has had a considerable impact on technology.
Latest Patents
One of his latest patents is the "Adaptive temperature compensated AC unlatch algorithm." This invention involves an information handling system, such as a disc drive, which includes a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The system identifies a region of the disc stack as a parking band, where the actuator assembly is held in a parked position by an actuator latch when power is not provided. The actuator latch and actuator assembly have different resonant frequencies based on environmental elements, including temperature. The actuator assembly is unlatched by measuring the environmental element and applying an alternating current to a voice coil coupled to the actuator, ensuring the frequency of the current is near the resonant frequency of the actuator assembly.
Another significant patent is "Enhanced adaptive feedforward control to cancel once-per-revolution disturbance by shaping the internal mode." This method produces a modified control signal to an actuator arm assembly of a disc drive to reduce runout. It involves generating a correction signal corresponding to a position error signal of a current track and determining a high pass filter transfer function to decrease the gain of unwanted frequencies. The filtered correction signal is then used to generate a modified control signal to the actuator arm assembly, effectively removing the runout on the next track.
