  • Method and apparatus for determining message transmission in mobile communication system when simultaneously using SPS and DRX
    Patent number: 9591522
    Abstract: A method for message transmission of a base station and message determination of a terminal in a mobile communication system is provided. The method includes, if a condition for operating in a first mode is met, generating a first message instructing to operate in the first mode, transmitting the first message to a terminal, receiving a response message for the first message, and determining whether the terminal has received the first message, wherein the first message transmission is performed within a time period.

  • HN epitope recognized by avian immune system and antigenic variant newcastle disease viruses carrying changes in the epitope
    Patent number: 8029801
    Abstract: The present invention relates to an epitope of HN protein in Newcastle disease virus which can be recognized by an avian immune system and an antibody against the epitope, a method for detecting a Newcastle disease virus by using the antibody, and an antigenic variant of Newcastle disease virus carrying changes in the epitope. The epitope of HN protein and the antigenic variant of Newcastle disease virus can be used for developing efficient vaccines, and further, in diagnosing the Newcastle disease virus rapidly and exactly.

  • Physical identification data addressing method using wobble signal, wobble address encoding circuit, method and circuit for detecting wobble address, and recording medium therefor
    Patent number: 7092329
    Abstract: A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, a method and circuit for detecting the wobble address and a recording medium therefor. Groove tracks are classified into odd groove tracks and even groove tracks. Address information indicating physical identification information is phase modulated using wobble signals having a predetermined phase difference between two adjacent groove tracks, and recorded in each groove track so that address information modulated using the wobble signals having the phase difference of 90° between adjacent two groove tracks can be a quadrature phase shift keying (QPSK) signal. Accordingly, a larger amount of data can be recorded on the recording medium, and since an interval in which a wobble signal disappears is not caused, recovery of a wobble clock signal can be advantageously performed.
