摘要:
An apparatus for detecting a network traffic abnormality includes: a pre-processing unit pre-processing traffics collected from at least one traffic collecting point in a network; a profiler modeling a normal traffic according to a characteristic of the traffic; an analysis model unit generating the thresholds based on the traffic; and an analyzer comparing a relative ratio of the traffic to the entire network traffics and the threshold and determining whether the traffic is abnormal. A combinational use of analysis methods using the relative ratio to the entire traffics and the absolute traffic volume takes into consideration of characteristics of a relative traffic ratio and absolute traffic volume, thereby providing a more reliable determination on whether the traffic is abnormal.

A method of providing a PoC service service in a mobile communication system is disclosed, by which a user's sensory duration can be reduced in case of switching a status of a traffic channel between a user equipment and a mobile communication network to an active mode from a dormant mode in the mobile communication system such as a CDMA network. The present invention includes a first step of transmitting the PoC service data from a first user equipment in the dormant mode via a short data burst, a second step of allowing the user equipment to enter an active mode via a traffic channel connection after completion of the first step, a third step of transmitting a reception acknowledgement signal (ACK) from a second user equipment having received the PoC service data via the short data burst, and a fourth step of receiving the reception acknowledgement signal (ACK) via a traffic channel.

A novel black matrix, a method for preparing the same, and a flat display device and an electromagnetic interference filter to which the black matrix is applied. The black matrix is prepared by exposing a photoactive compound to form a latent pattern of nuclei for crystal growth and treating the latent pattern of nuclei for crystal growth with a metal salt solution to give a metal particle-deposited pattern; forming an electroless Ni-plated layer on the metal particle-deposited pattern; and forming an electroless Cu-plated layer on the electroless Ni-plated layer. Exhibiting improved black tone, which is achieved only by a selective multilayer plating process, without using expensive vacuum sputtering apparatus or a photolithographic process, the black matrix can be applied to various flat display devices. In addition, due to improved electric conductivity, the black matrix can be used in an electromagnetic interference filter, without employing an additional front surface blackening process.

A liquid crystal display device is provided. The liquid crystal display device includes: a liquid crystal display panel having an upper substrate and a lower substrate, a backlight assembly; a top cover surrounding the liquid crystal display panel, and a pad located on an upper surface of the lower substrate. The pad distributes a force applied by the top cover to the lower substrate, thereby reducing light leakage of the backlight assembly.

An air purifier including: a filter which removes contaminants from air passing therethrough; a fan which generates a flow force to pass air through the filter; and a rotating body rotatably mounted in the air purifier and defining a flow path around the fan, a discharge direction of the flow path being varied by rotation of the rotating body.
摘要:
A clothing dryer including a first exhaust duct mounted inside the clothing dryer and adapted to exhaust air from the clothing dryer and a second exhaust duct to be inserted on the first exhaust duct. A pressing portion is mounted on the first exhaust duct to press both the first and second exhaust ducts, and a fixing portion is affixed to a rear surface cover of the clothing dryer so as to fixedly maintain the first exhaust duct relative to the rear surface cover. A positioning portion is provided to couple the pressing portion to the first exhaust duct and to prevent additional insertion of the second exhaust duct beyond a predetermined length. Thereby, the first and second exhaust ducts are able to be easily connected to each other while preventing optional adjustment of a connection length therebetween, and the first exhaust duct is stably kept so as not to rotate when it is assembled in the clothing dryer. Further, the first and second exhaust ducts are self-sealed to each other.
摘要:
A recording medium read/write method and apparatus are disclosed. The present invention records version information of a corresponding recording medium as read/write control information within the recording medium. The version information includes write compatibility version information and read compatibility version information. The read/write apparatus efficiently performs the read/write of the recording medium with reference to the version informations recorded within the recording medium.
摘要:
A VCSEL includes a substrate having a partially removed portion; a metal-assisted DBR having a metal layer and a first mirror stack, wherein the metal layer is located at the partially removed portion of the substrate; an active region having a plurality of quantum wells over the metal-assisted DBR; and a second mirror stack over the active region, wherein a number of alternating layers of the first mirror stack is substantially smaller than a number typically required for a VCSEL without the integrated metal reflector. Such a metal-assisted DBR is especially useful for a long-wavelength VCSEL on a InP substrate or a red-color VCSEL on a GaAs substrate.
