  • Patent number: 8312180
    Abstract: An address management method and a video apparatus using the same are provided. The address management method includes determining whether an external device is connected or not; when determining the connection to the external device, generating an invalidation message for invalidating an address; and transmitting the generated invalidation message to the external device. Accordingly, when the port connection is changed, the physical address can be correctly updated by invalidating the former physical address.

  • Publication number: 20120283300
    Abstract: This application relates to a novel benzo-heterocycle derivative and more particularly, it relates a composition for preventing and treating cancer or for inhibiting metastasis comprising benzo-heterocycle derivative or pharmaceutically acceptable salts thereof as an active ingredient. The present inventors confirmed that KRS has an effect on cancer metastasis by facilitating cancer (or tumor) cell migration through interaction with 67LR, and also found that a substance inhibiting the interaction between KRS and 67LR can prevent and treat cancer by inhibiting cancer cell metastasis. Accordingly, the composition of the present invention can inhibit cancer metastasis, and thus provide a novel means for prevention and treatment of cancer.

  • Patent number: 8180929
    Abstract: An address management method and a device thereof are provided. The address management method includes checking by a device whether logical addresses are currently being used by external devices; and setting by the device a non-use logical address as a logical address of the device regardless of the type of the device, if the device determines that the non-use logical address exists. Therefore, a device may use all logical addresses regardless of its device type, and may also have a logical address even though all logical addresses corresponding to its device type are currently being used.

    Abstract: An output driver includes a pull-up circuit and a pull-down circuit coupled to an output terminal and a capacitor having a first terminal coupled to a gate terminal of a P-channel transistor of the pull-up circuit and a second terminal configured to receive a drive signal. The output driver further includes a drive circuit coupled to the first terminal of the capacitor and configured to transfer charge from a power supply node to the first terminal of the capacitor when the drive signal is at a signal ground voltage and to decouple the first terminal of the capacitor from the power supply node when the drive signal is at a voltage level greater than the signal ground voltage such that a voltage swing of a signal generated at the gate terminal of the P-channel transistor is constrained to be less than a voltage of the power supply node with respect to the signal ground voltage.

  • Patent number: 8088663
    Abstract: A planar pass gate NFET is designed with the same width as a planar pull-down NFET. To optimize a beta ratio between the planar pull-down NFET and an adjoined planar pass gate NFET, the threshold voltage of the planar pass gate NFET is increased by providing a different high-k metal gate stack to the planar pass gate NFET than to the planar pull-down NFET. Particularly, a threshold voltage adjustment dielectric layer, which is formed over a high-k dielectric layer, is preserved in the planar pass gate NFET and removed in the planar pull-down NFET. The combined NFET active area for the planar pass gate NFET and the planar pull-down NFET is substantially rectangular, which enables a high fidelity printing of the image of the combined NFET active area by lithographic means.
