Abstract: A method for transmitting and receiving multimedia files using a WUSB(Wireless Universal Serial Bus) is provided to enable a user to download a multimedia file using a WUSB, without the necessity of executing a complicated cable connection, to actively select and regenerate a multimedia file, and to automatically regenerate a multimedia file. In case a terminal accesses a multimedia file server for the first time, the multimedia file server executes information registration work for the terminal(S220). Then the multimedia file server creates a list of multimedia files, which can be regenerated in the terminal, and transmits the created list to the terminal through a WUSB host(S240,S250). The terminal selects one among the received list and transmits a multimedia file transmission request message(S260,S270). The multimedia file transmission request message is delivered to the multimedia file server through the WUSB host(S280). The multimedia file server transmits the requested multimedia file to the terminal through the WUSB host(S290,S300). The terminal regenerated the received multimedia file(S310).

Title: Motor controller and out-of-control detecting method

Abstract: A motor controller by which out-of- control can be correctly detected in a short time by a simple calculation using a controlled variable of a motor and the safety of a machine such as a crane can be improved. The coordinate system of the voltage and current of an AC motor are converted into a coordinate system of two axes (d, q) to control the AC motor, and out-of-control is detected from the d- and q-components of the voltage or current. Using the exciting current feedback value Id which is the d-component of the current and the torque current feedback value Iq which is the q-component, if a value computed according to Thetai =tan-1(Iq/Id) increases above a predetermined value, the motor is judged to be out of control.
