Abstract: Disclosed herein are a virtual controller client mobile terminal-based virtual game controller and a remote control system using the same. The remote control system includes a virtual controller server and a virtual controller client. The virtual controller server generates button setting information including mapping relationship between key inputs and virtual input messages, transfers the button setting information, extracts a key input from a virtual input message, and provides the key input to the application. The virtual controller client specifies an arrangement and attributes of virtual buttons based on the button setting information, generates a virtual button screen on the touch screen of the mobile terminal, generates a touch input message based on touch event objects generated based on touch signals for regions corresponding to the virtual buttons, and converts the touch input message into a virtual input message and outputs the virtual input message.

Abstract: A method of processing data in a memory system including a control unit and a hybrid memory device having a first memory and a second memory, includes; receiving first write data, storing the first write data in the first memory and assigning a first group state from among a plurality of group states to the stored first write data in response to first attribution information, completing a data processing operation in the memory system directed to the stored first write data that changes the attribution information associated with the stored first write data by monitoring of the first attribution information using an operating system running on the memory controller, and changing the first group state assigned to the stored first write data to a second group state from among the plurality of group states, the second group state having a different priority than a priority for the first group state.

Abstract: An apparatus and method for controlling adaptive reclosing based on transient stability of a power transmission line are disclosed. The apparatus includes a power angle calculation unit, an integral square error (ISE) second-order differential calculation unit, a stability determination unit, and a disconnection signal generation unit. The power angle calculation unit acquires the instantaneous value of a power angle based on voltage and phase angle measurement signals. The ISE second-order differential calculation unit acquires the instantaneous value of the second-order differential of the ISE of the power angle. The stability determination unit determines whether a system is stable or unstable based on the transitions in the instantaneous value of the second-order differential of the ISE.
