Abstract: An electronic device and a method of operating the same are provided. The electronic device includes a controller configured to receive a baseband signal corresponding to an infrared ray (IR) signal for controlling a peripheral device, to determine a first carrier frequency corresponding to the baseband signal based on remote controller code information included in the baseband signal, and to combine the first carrier frequency with the baseband signal; and a transmitter configured to transmit the baseband signal combined with the first carrier frequency to the peripheral device.

Abstract: A remote control apparatus and method for controlling a function of a display apparatus are provided. The remote control apparatus includes a communications device for communicating with a display apparatus; buttons for receiving a user command relating to function control of the display apparatus; a jog switch for allowing directional movement manipulation and push manipulation; and a controller for, after the user command is input through the buttons, generating and sending a control signal to set a different function of the display apparatus based on a manipulation state of the jog switch.

Abstract: A method of determining a broadcast reception state of a broadcast receiving apparatus includes receiving a broadcast signal using a tuner; checking a reception state of the broadcast signal; changing a wireless communication connection state of the wireless communication module if the reception state of the broadcast signal is abnormal and rechecking the reception state; and determining the reception state as an abnormal reception state due to interference with a wireless communication frequency if a result of rechecking the reception state indicates the reception state is normal.

Abstract: An organic rankine cycle (ORC) turbo generator for prevention of penetration of a working fluid is provided, which can block penetration of the working fluid from a turbine into a generator, thereby improving the efficiency of power generation. The turbo generator comprises: a turbine including a turbine housing, a turbine blade and a fluid injection nozzle; a generator including a generator housing connected to the turbine housing, a rotor rotatably mounted inside the generator housing and a rotary shaft mounted to the turbine blade, and a first bearing and a second bearing mounted at the front and rear ends of the rotor; and working fluid penetration-preventing means adapted to block the pressure generated from the turbine so as to prevent the working fluid injected from the fluid injection nozzle from being penetrated into the generator.
