Abstract: PURPOSE: An indoor location recognition system and a location recognition method thereof are provided to accurately determine a location by supporting multiple cells or multiple tags in a wireless sensor network. CONSTITUTION: One or more location recognition devices(110) include a tag. The location recognition device transmits packets for determining a location. A coordinator anchor(120d) selects a specific location recognition device for determining the location from the one or more location recognition device by allocating time slots. A plurality of anchors responds for the packets transmitted from the selected specific location recognition device. The location recognition device determines a location by measuring packet response time from the anchors.

Abstract: PURPOSE: A method is provided to use a vessel electronic device interface designed according to the existing NMEA-0183 without change of hardware such as replacement of a device in the NMEA-2000 standard, thereby reducing replacement cost and time resulted from change of a communication standard. CONSTITUTION: A reception unit converts a message transmitting through RS-422 of the NMEA-0183 communication protocol to the USART(Universal Asynchronous Receiver/Transmitter) communication protocol. The control and conversion unit analyzes and converts the converted message through the reception unit using an 8bit CAN MPU chip, AT90CAN128-16AU and outputs a NMEA-2000 type message.

Abstract: PURPOSE: A method for minimizing the malfunction of an EPIRB(Emergency Position Indicating Radio Beacon) with an enhanced seawater sensing method is provided to launch distress alarms by forming conductivity when four contact points have the same resistance in the automatic mode of the EPIRB. CONSTITUTION: A method for minimizing the malfunction of an EPIRB with an enhanced seawater sensing method is as follows: Seawater resistance values are measured by a Kelvin double bridge circuit. According to the variation of the measured seawater resistance values, an EPIRB is separated from an automatic release device only in a completely submerged state.

Abstract: PURPOSE: An intelligent image monitoring method for ship is provided to supply the convenience and expandability of a hardware configuration in the implementation of a monitoring system by detecting movement by an image monitoring system by using an image. CONSTITUTION: An obtained image frame is converted into a gray scale. After the binarization of the converted image frame, a GMM(Gaussian Mixture Model) is applied. A value having the change of pixel among result values caused by the application of the GMM is determined as a white pixel value. The white pixel value is counted. The completed frame of the next page is inputted. The white pixel value of the image frame is counted. The movement is detected in comparison with a count value and a threshold value.

Abstract: 본 발명은 알루미늄 합금판으로 제작된 간단한 보강재만으로도 충분한 구조강도를 확보할 수 있는 알루미늄제 레저선박의 초경량 선체구조에 관한 것이다. 본 발명에 따르면, 늑골 및 거더가 아닌 소수의 보강재를 사용하더라도 레저선박에 필요한 구조강도를 충분히 확보할 수 있을 뿐만 아니라, 늑골 및 거더와 같은 보강재의 과도한 사용을 생략함으로써 레저선박의 경량화가 가능해진다. 또한 한 가지 두께의 알루미늄 합금판으로 선체를 제작하므로 용접가공이 용이하여 작업공수와 제작기간을 상당히 단축시킬 수 있다.
