Title: Hao Ruan: Innovator in Optical Disc Technology
Introduction
Hao Ruan is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of optical disc technology, holding 2 patents that showcase his innovative approach to solving complex problems in data transmission and servo control.
Latest Patents
Hao Ruan's latest patents include a "Radial servo device for super-resolution optical disc and servo control method therefor." This invention features a radial servo control device that incorporates an excitation light source, a servo light source, an integrated optical path, focusing units, a servo light detecting unit, and a drive control unit. The drive control unit is designed to preset N detection error reference values for each guide layer trench irradiated by servo light. It controls the positions of the focusing units in N data tracks based on the comparison between the detection result of servo reflected light and the detection error reference values. This device is applicable to various super-resolution optical discs, achieving precise radial servo control of super-resolution data tracks without compromising the wavelength of servo light.
Another notable patent is focused on "Transmission latency reduction." This invention describes systems and methods for minimizing transmission time by generating uniform-sized original packets from a data frame. These packets include an identifier, total block number, block index, and data. The packets are encoded to form redundant packets, which are transmitted by individual modems over different channels. The transmission rates are configured to minimize free space in the modem's input buffer, based on feedback from the receiver regarding the difference between transmission and reception rates.
