Title: The Innovative Contributions of Ke Du
Introduction
Ke Du is a prominent inventor based in Oklahoma City, OK (US), known for his significant contributions to technology and engineering. With a total of 7 patents to his name, Du has made remarkable advancements in the field of data storage and communication systems.
Latest Patents
One of Du's latest patents is titled "Low frequency signal baseline shift compensation in a disc drive." This invention provides an apparatus and method for removing baseline shift in low frequency readback signals of a disc drive. The disc drive includes a head that is controllably positionable adjacent to tracks on a rotatable disc, a servo circuit that controls the head's position in response to readback signals, and an adjustable filter that is connected between the head and the servo circuit. When a baseline shift is detected, the adjustable filter's response characteristics are modified to eliminate the shift from the readback signals.
Another notable patent is the "Dual decision feedback equalizer with selective attenuation to improve channel performance." This invention enhances error rate performance in communication channels by utilizing a dual decision feedback equalizer (DDFE) with selective attenuation. The improved DDFE consists of two decision feedback equalizers that independently generate decisions based on transmitted signals. When a mismatch is detected, selective attenuation is introduced to improve decision-making accuracy, thereby enhancing the overall performance of the communication channel.
