摘要： A terminal device may backup data in a cloud server. The cloud server may generate a virtual apparatus to perform substantially the same operations as the terminal device, and may install an application in the virtual apparatus prior to the application being installed in the terminal device, thereby performing a virus check before the application is installed in the terminal device. In addition, the terminal device may store backup data in the cloud server. If the terminal device malfunctions, the terminal device may be restored by receiving the stored backup data from the cloud server.

摘要： A terminal may backup data in a cloud server. The cloud server may generate a virtual device to perform substantially the same operations as the terminal, and may install an application in the virtual device if the application is determined to be unreliable by the terminal. The cloud server performs a reliability evaluation of the unreliable application and transmits the results of the reliability evaluation to the terminal. In addition, the terminal may store backup data in the cloud server. If the terminal malfunctions, the terminal may be restored by receiving the stored backup data from the cloud server. The terminal may remotely execute an application installed in the virtual device.

摘要： A frequency up and down converter, in which, when down converting a high frequency signal into an intermediate frequency signal or up converting an intermediate frequency signal into a high frequency signal by controlling switching elements using a local oscillator signal, a signal with a frequency to be converted is controlled a number of times during one cycle of the local oscillator signal, whereby the local oscillator signal with a frequency lower than an original frequency may be used. Transistors are added in parallel to switching transistors disposed in a frequency down conversion unit or a frequency up conversion unit, and local oscillator signals with predetermined phases and pulse widths are provided to the gates of the transistors such that a high frequency signal or an intermediate frequency signal is transferred to an output terminal at least two times during one cycle of a local oscillator signal.
