  • Patent number: 10356113
    Abstract: Disclosed herein are an apparatus and method for detecting abnormal behavior in a main device and a terminal device, included in a control network, using a whitelist. The apparatus for detecting abnormal behavior includes an information collection unit for collecting system information about the main device and system information about the terminal device and a detection unit for detecting abnormal behavior in the main device and the terminal device by comparing a whitelist with system information that includes the system information about the main device and the system information about the terminal device, wherein the whitelist includes a process whitelist, a file whitelist, and a network whitelist.

  • Patent number: 10305467
    Abstract: A radio frequency switch circuit includes: a radio frequency switch configured to control a radio frequency signal passing between a signal port and an antenna port; a first buffer configured to generate the first control voltage in response to a second control voltage; a second buffer configured to receive a third control voltage and configured to generate the second control voltage in response to the third control voltage; a first power supplier configured to supply a first high voltage to the first buffer and configured to supply a second high voltage to the second buffer; and a second power supplier configured to supply a first low voltage to the first buffer and configured to supply a second low voltage to the second buffer.

  • Patent number: 8497260
    Abstract: 2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for ?-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes: wherein R1-R4, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight ?-amyloid peptide binding compound, generation of malignant high-molecular weight ?-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.

  • Publication number: 20100046910
    Abstract: A media signal sink (100A) and an image reproduction method thereof are disclosed. The media signal sink (100A) is adapted to selectively reproduce a first image signal and a second image signal, and includes a user command input unit (606) for inputting an image signal switch command signal in a state in which the first image signal is reproduced, a controller (602) responsive to the image signal switch command signal for stopping the reproduction of the first image signal and reproducing the second image signal, and a display unit (604) for displaying an image based on a reproduction operation of the controller (602). When a resumption command signal for the first image signal is inputted through the user command input unit (606), the controller (602) again reproduces the first image signal beginning with a portion of the first signal in which the reproduction of the first image signal has been stopped, in response to the resumption command signal.
