Abstract: A controller and method for operating a plurality of capacitors of a first phase, wherein the first phase is one of a plurality of phases applied to the motor, a plurality of first switching elements of the first phase, and a plurality of second switching elements of the first phase. The plurality of capacitors charge DC voltage from a battery that applies voltage to the motor. The plurality of first switching elements convert the DC voltage to AC voltage. The plurality of second switching elements switch so that any one of the plurality of capacitors or the plurality of first switching elements is selectively connected to the motor.

Abstract: A method and a device for registering three-dimensional data are disclosed.

Abstract: The present disclosure relates to a method and system for providing large-scale group communications and, more particularly, to a method and system for providing a real-time service to a plurality of geographically distributed terminals on the same session with little degrading in image quality. A large-scale group communication method according to at least one embodiment may include connecting each of a plurality of geographically distributed terminals to one of a plurality of distributed data transfer systems (DTS) on a same session and transmitting respective media data through the connected DTS.

Abstract: Disclosed is a method and system for allowing a server system to control a video structure of a client system through a video of an optimized size and to transmit the controlled video structure in a system in which video conference is remotely available. The method includes a step of allowing a control unit of any one client system to request a main control unit of a server system to change the video structure which includes coordinates and video size; and allowing the main control unit to make a change so as to coincide with the request of the control unit of the client system, which has requested the change of the video structure being currently outputted to a video conference monitor, and to transmit the change to a control unit of each client system.
