  • METHOD FOR MODULATING VARIABLE BINARY OFFSET CARRIER WITH DISCRETE TIME-VARIANT FREQUENCY, AND SATELLITE NAVIGATION SIGNAL GENERATOR USING THE SAME
    Publication number: 20220299654
    Abstract: Disclosed are a method for modulation of a variable binary offset carrier (VBOC) having a discrete time-variant frequency and a satellite navigation signal generator using the same. The method for modulation of a VBOC having a discrete time-variant frequency may comprise: generating navigation message data; generating a carrier; generating a VBOC subcarrier; generating a pseudo-random code; synthesizing the pseudo code and the VBOC subcarrier; and synthesizing a synthesized signal of the pseudo code and the VBOC subcarrier, the carrier, and the navigation message data.

  • LED lighting device
    Patent number: 9752768
    Abstract: An LED lighting device includes a case unit forming a light emitting space, wherein resting surfaces are formed at predetermined areas on the inner side of the case unit, substrates having LEDs mounted thereon and respectively rested on the plurality of resting surfaces, and heat-dissipating units formed in the outer side of the case unit for heat dissipation. Lifespan and user convenience can be improved.

  • CALIXCROWN DERIVATIVES, A PROCESS FOR THE PREPARATION THEREOF, A SELF-ASSEMBLED MONO-LAYER OF THE CALIXCROWN DERIVATIVES PREPARED BY USING THE SAME AND A PROCESS FOR IMMOBILIZING A PROTEIN MONO-LAYER BY USING THE SELF-ASSEMBLED MONO-LAYER OF THE CALIXCROWN DERIVATIVES
    Patent number: 6485984
    Abstract: The present invention is to provide calixcrown derivatives of formulae 1 to 3 requisite for the preparation of a self-assembled monolayer as well as a process for the preparation thereof. Further the present invention is to provide a self-assembled monolayer which is produced by immersing a gold substrate or related metal substrate in an organic solution containing said calixcrown derivatives of formulae 1 to 3. Still further the present invention provides a process for fixing a protein monolayer by fixing proteins having molecular weight of not less than 20,000D (20KD) on said self-assembled monolayer.
