20110084735	SCART INTERFACE CONTROL CIRCUIT AND VIDEO DEVICE USING THE SAME - A SCART interface control circuit outputs a mode switch signal to a switch signal pin of the SCART interface according to standby, widescreen and normal modes of video signals. The SCART interface control circuit comprises a first voltage circuit, a second voltage circuit, a voltage combination circuit and an amplifier circuit. The first and second voltage circuits output first and second voltage signals according to the video signal modes, respectively. The voltage combination circuit combines the first and second voltage signals into a combination voltage signal. The amplifier circuit amplifies the combination voltage signal so as to output the mode switch signal for indicating the video signal modes.	04-14-2011

20100148710	APPARATUS AND METHOD FOR CONTROLLING A BLDC MOTOR - An apparatus for controlling a BLDC motor includes a frequency controller configured to increase frequency of a drive signal that is applied to the motor to reach a first target speed at a relatively low speed region. The apparatus also includes a sensorless controller configured to observe location of a rotor of the motor at the low speed region, and provide a control signal to the motor by comparing a command speed with an estimated speed based on detection of a voltage and/or a current of the motor at a relatively high speed region. Further, the apparatus includes a control unit configured to select one of the frequency controller and the sensorless controller based on the speed of the motor.	06-17-2010
