Abstract: An apparatus and a method for detecting a phase delay of a resolver are provided. The apparatus includes a resolver configured to output a signal corresponding to a rotation angle of a motor, an excitation signal generator configured to generate an excitation signal using a square wave signal, and a controller configured to differentiate the signal to obtain a differential signal, detect a time when the differential signal meets a reference voltage as a peak time of the signal, and detect a phase delay time of the signal based on the peak time of the signal and an edge time of the square wave signal.

Abstract: The present invention relates to a document processing system using augmented reality and virtual reality, and a processing method therefor. The document processing system of the present invention shares contents of an object so that one user can write the contents of the object at the location of the object displayed in an augmented reality or virtual reality image to write and store various types of virtual documents and allow other users to view the virtual documents in the augmented reality or virtual image. The document processing system writes and shares the virtual documents by using a mobile terminal capable of expressing augmented reality or virtual reality. The document processing system shares the virtual documents between mobile terminals in a P2P method or a method of using a server.
