  • APPARATUS AND METHOD FOR STABILIZING A LIGHT
    Publication number: 20180138653
    Abstract: An apparatus and a method for stabilizing output of a light source are disclosed. The stabilization device located outside of a light source comprises a stabilization element, and a stabilization controller configured to control a light output from the light source so that a part of the light output and other part of the light cross propagate in the stabilization element.

  • APPARATUS AND METHOD FOR COMPRESSING AND DECOMPRESSING DATA
    Publication number: 20140376605
    Abstract: Disclosed are methods and apparatuses for compressing and decompressing data at a sample rate lower than a Nyquist sampling rate for the data. The data compression apparatus comprises a domain converting part performing a domain conversion on input data to generate domain-converted input data, and a data compression part generating compressed data by down-sampling the domain-converted input data at a sampling rate lower than a Nyquist sampling rate. Therefore, data to be transmitted can be compressed in a transmitting end by sampling the data at a sampling rate lower than a Nyquist sampling rate, and then the data can be reproduced in a receiving end. Therefore, a higher compression ratio can be achieved as compared with that of conventional technologies.
