Abstract: Provided is a system and method for creating and providing a mosaic image based on an image tag-word by a mosaic service providing server, which includes: determining each tag-word for each image and classifying a plurality of images according to the determined tag-word; determining a target image among the plurality of images; providing a pixel image selection interface for selecting a pixel image for mosaicizing the determined target image based on the tag-words of the plurality of images; and creating a mosaic image for the target image based on the pixel image selected through the pixel image selection interface.

Abstract: Disclosed is a realization method of a speed signal of a motor using a linear Hall-effect sensor that may include the steps of: determining coordinate values on a x-y coordinate system using a Hall signal in the form of a sine wave of a linear Hall-effect sensor, evaluating a summed coordinate value of the above coordinate values, calculating the angle (?) formed by a summed coordinate value and the x axis; determining the quadrant of the resulted angle (?), and determining a speed signal by dividing the final motor displacement value by the rate of time change.

Abstract: Disclosed is a realization method of a speed signal of a motor using a linear Hall-effect sensor characterized by comprising the steps of: by using a Hall signal in the form of a sine wave of a linear Hall-effect sensor, determining coordinate values on a x-y coordinate system of the position sensor; evaluating a summed coordinate value of the above coordinate values; calculating the angle(?) formed by a summed coordinate value and the x axis; determining the quadrant of the resulted angle(?); and determining a speed signal by dividing the final motor displacement value by the rate of time change.
