The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

A radar tracking apparatus and method are provided. The radar tracking apparatus includes an &#x3b1;-&#x3b2; tracking filter, wherein the &#x3b1;-&#x3b2; tracking filter includes: a tracking index unit calculating a tracking index for obtaining &#x3b1; and &#x3b2; filter gains of an &#x3b1;-&#x3b2; tracking filter, based on changes in the measurement error covariance of a radar-measured value that occur when the measured value of target is converted from a polar coordinate system to a rectangular coordinate system; and a filter gain update unit calculating the variations of &#x3b1; and &#x3b2; filter gains, based on the partial differential coefficient of the changing rate of the &#x3b1; and &#x3b2; filter gains with respect to the changing rate of the tracking index and the variations of the tracking index, and updating the &#x3b1; and &#x3b2; filter gains.

Disclosed is a low power and high density source driver and a current driven active matrix organic electroluminescent device having the same, in which all elements operate at a normal voltage and all circuits of the source driver are shielded from a high voltage of a panel. The source driver includes: a shift register for generating an enable signal for storing data; a data latch circuit for storing digital data inputted from an exterior; a line latch circuit for sequentially storing the data in response to the enable signal and outputting the stored data in parallel at one time in response to a load signal; a current type digital-to-analog converter for converting the digital data outputted from the line latch circuit into an analog signal, the analog signal being outputted in a form of a current signal; and a high voltage shield circuit for transferring the output of the current digital-to-analog converter to source lines of an external panel and for shielding internal circuits from a high voltage of the panel. The shift register, the data latch circuit, the line latch circuit, the current type digital-to-analog converter and the high voltage shield circuit are driven at a normal voltage.
