Abstract:
본 발명은 원 칩 형태로 심장 질환자의 체내에 삽입되어 심장 질환을 검출하는 피크 심장 박동 검출 시스템에 관한 것으로, 특히 고속으로 빈맥성 이상상태 또는 서맥성 이상상태를 판단할 수 있는 시스템에 관한 것이다. 본 발명은 피크 검출 모듈을 통해 심실 또는 심방 신호를 센싱하여 피크를 검출하고, 검출된 피크 정보를 통해 심장의 이상상태를 판단한다. 좀더 자세하게, 본 발명은 검출된 피크의 문턱 레벨이 최소 문턱 레벨 이탈 후 경과시간을 측정하여 빈맥성 이상상태 유무를 판단하고, 최소 문턱 레벨 유지 시간을 이용하여 서맥성 이상상태 유무를 빠르게 판단함으로써 하나의 심장 박동 검출 시스템에서 빈맥성 이상상태와 서맥성 이상상태를 모두 판단할 수 있다.

Abstract:
PURPOSE: A method for determining boundary strength in a deblocking filter is provided to simplify some parts of a boundary strength generation process by an encoding/decoding condition. CONSTITUTION: An integrated comparison unit(240) compares the identity of a reference image and motion vector in X, Y directions among neighboring blocks. A logical unit(210) determines boundary strength by discriminating the coding type of a macro block. A second logic unit(220) determines boundary face intensity by using an encoding residual coefficient. A third logic unit(230) determines the boundary face intensity through the operation result of the integration comparison unit. According to the intra prediction coding of a processing macro block, a clock gating unit(250) controls the integration comparison unit and the operation of the third logic unit and the second logic unit.

PURPOSE: A de-blocking filter apparatus of a pipeline structure using a vertical filter and a horizontal filter reusing the data is provided to reduce the entire buffer occupancy by removing the use of pre-buffer. CONSTITUTION: A buffer memory(210) stores the row direction data of a macro block. A B buffer memory(220) stores the column direction data of the macro block. A horizontal filter(260) performs horizontal filtering operation about a vertical edge by one or more pipe stages by the row direction data. A vertical filter(270) performs vertical filtering about the horizontal edge.

Abstract:
PURPOSE: A network automatic protection system is provided to protect a network device by disconnecting the power source of a network when a stroke of lightning is generated near the network. CONSTITUTION: A lightning stroke detection sensor(120) senses the lightning stroke near a first network(110). A cable connection device(130) generates lightning stroke generation estimation information according to the signal of the lightning stroke detection sensor. A first lightning stroke interruption control device(140) comprises a sensor transceiver, a controller, and a network power disconnecting part. The sensor transceiver receives the lightning stroke generation estimation information. The controller generates a first network turn-off request based on the lightning stroke generation estimation information. The network power disconnecting part disconnects the power source of the first network by the first network turn-off request or a network user.
Abstract:
PURPOSE: A system and a method for detecting heart-pulse are provided to accurately detect the peak of a ventricle signal or an atrium signal from the heart of a patient with a tachycardia disease. CONSTITUTION: A peak detecting unit(104) detects the peak of a ventricle signal or an atrium signal according to an adaptive threshold level. After the maintaining time of the adaptive threshold level is passed, the peak is re-detected. A system determining unit(114) indicates the disease in the heart based on a detected peak interval. A feedback data processing unit(116) regulates the maintaining time of the threshold level based on a pre-set value.
Abstract:
PURPOSE: An image decoding method and a device thereof are provided to reduce image decoding time by performing deblocking filtering differently according to a characteristic of an image. CONSTITUTION: A target area for performing filtering by a frame unit is configured according to a characteristic of an image(510). The characteristic of the image is at least one between size and resolution of the image. A macro block included in the target area is deblocking filtered by the frame(520). A macro block not included in the target area skips the deblocking filter(525). The target area is an area except for the outer portion corresponding to size or the rate determined in the frame according to a characteristic of the image.
