A washing machine and unbalance detection method using the same, which is capable of efficiently detecting unbalance of a rotation tub. A washing machine includes: a washing motor rotating a rotation tub accommodating laundry; a motor velocity detection unit detecting a velocity of the washing motor and outputting a motor velocity signal; and a controller determining whether unbalance of the rotation tub occurs according to an unbalance level determined on the basis of a velocity ripple of the motor velocity signal, and controlling the washing motor according to the determination result. A method of detecting unbalance of a rotation tub accommodating the laundry in a washing machine includes: driving a washing motor in order to rotate the rotation tub; detecting a velocity of the washing motor, and outputting a motor velocity signal; extracting a velocity ripple of the motor velocity signal, the velocity ripple being generated while detecting the velocity of the washing motor; operating the extracted velocity ripple, and detecting an unbalance level; and comparing the detected unbalance level with a reference value, and determining whether the unbalance of the rotation tub occurs.

A median filtering method makes a plurality of pixel data into a block of fixed unit area which includes a central pixel and a plurality of ambient pixels adjacent to the central pixel. Pixel data within the unit area is divided into sub unit areas which are smaller than the unit area. The data value of the divided pixel data is arranged in a fixed order for each of the sub unit areas. An intermediate value is determined from the arranged pixel data in each of the sub unit areas. An average value of the intermediate values which are extracted from each of the sub unit areas, and the central pixel data is determined corresponding to the central pixel of the unit area with the average value.

A method and system for supporting an XQuery trigger in XML-DBMS based on relational DBMS is provided. In an Ubiquitous environment where XML data are incessantly generated by an enormous number of objects, so as to overcome inconvenience and its resultant reduction of performance in which a user should query after checking a change of XML-DBMS one by one, in XML-DBMS based on relational DBMS, the present invention supports an XQuery trigger technique based on SQL trigger automatically executing insert, update and delete statements, and a storage or external procedure related with the change of data when a change of data is generated at a specific table in a conventional relational DBMS.
摘要:
Two-dimensional and three-dimensional optical coherence tomography is obtained by differential imaging of full-frame interference images using a white light source. Full-color tomographic imaging is also possible by processing the three-color channels of the interference images. A technique is described to obtain two-dimensional OCT images with full natural color representation. In a particular embodiment, the interference image is acquired using a color camera and the three-color channels are processed separately, recomposing the final image. In an additional embodiment, the interference images are acquired using separate red, blue and green light sources and the three color channels are combined to recompose the final image.

Disclosed is a high voltage bobbin of a fly back transformer for outputting high voltage. The high voltage bobbin of the invention comprises a bobbin body having a central hole for receiving a low voltage bobbin wound with a low voltage wire; input and output terminal sections integrally formed in upper and lower portions of the bobbin body and mounted with pluralities of input and output terminal pins; a plurality of insulating film layers wound on an outer surface of the bobbin body; high voltage wires each wound between two adjacent ones of the insulating film layers; and input and output hooks integrally formed on the outer surface of the bobbin body. The input hook catches a first one of the high voltage wires before the first wire is wound on the bobbin body, and the output hook catches the first wire wound on the bobbin body before the first wire is extended to the outside. The invention excludes winding a first insulating film on the high voltage bobbin before winding a first wire on the high voltage bobbin in order to save fabrication cost as well as decrease the number of process steps thereby enhancing the competitiveness of the high voltage bobbin and thus the fly-back transformer.
