摘要:
A cable to waveguide transition apparatus having a signal accumulation form of a backshort is disclosed. The cable to waveguide transition apparatus having a signal accumulation form of a backshort, includes: a waveguide; a RF probe for transferring a radio frequency (RF) signal to the waveguide; and a backshort having the signal accumulation form for reflecting the RF signal excited from the RF probe, wherein the backshort reflects a first fundamental frequency signal excited from the RF probe to have a phase identical to a phase of a second fundamental frequency signal excited from the RF probe to an aperture of the waveguide, and reflects a first 2-order harmonic frequency signal excited from the RF probe to have a phase reverse to a phase of a second 2-order harmonic frequency signal excited to an aperture of the waveguide in order to eliminate the 2-order harmonic frequency signal.

A graphic data file containing instructions for displaying graphic data on a display device, the graphic data file having a header identifying the start of the graphic data file, a plurality of portions of instruction data following the header and each portion of instruction data having an instruction for controlling the graphic data of a predetermined size to be displayed and frame information to determine an order and a period of time for displaying the graphic data. A method for generating independent graphic data files including instructions for controlling a process of the graphic data files to be displayed on a display device, and to a corresponding medium and a player. The inventive method comprises the steps of: generating a header containing the information for identifying the start of the graphic data file; generating a plurality of instruction data following the header, each of the instruction data comprising one instruction for controlling the graphic data file of a predetermined size to be displayed on the display device and frame information for determining the order and a period of time of the instruction to be displayed; and generating a tail containing the information for identifying the end of the graphic data file following the plurality of instruction data.
摘要:
A mobile terminal having security diagnosis functionality and a method of making a diagnosis on the security of the mobile terminal are provided. The mobile terminal includes a system check unit, an interface unit, a blacklist check unit, and a security diagnosis unit. The system check unit collects the basic information of the mobile terminal by performing a system check on the mobile terminal. The interface unit provides the basic information of the mobile terminal to a user and receives a control command from the user. The blacklist check unit checks whether at least one application installed in the mobile terminal is present in a blacklist registered on a server. The security diagnosis unit checks whether an abnormality has occurred in the corresponding application based on results of the comparison between the basic information of the mobile terminal with preset abnormality detection reference information and the control command.
