  • Patent number: 8732842
    Abstract: A method and an apparatus which permits intuitive management of a variety of digital contents stored in a mobile device. In a method for managing the contents, the mobile device determines a type of the content when a play of the content is ended. If the content is digital rights management (DRM) content, the mobile device checks a license count for authorized access to the DRM content and then determines whether or the license has expired or will expire shortly. If the license has expired, the mobile device removes the license-expired DRM content, or alternatively transfers the license-expired DRM content to a specified folder.

  • Patent number: 8321091
    Abstract: Provided is a backward motion control technology for a car. The car comprises a backward-motion control terminal, a control signal converter, and a backward-motion controller. The backward-motion control terminal outputs a first backward-motion control signal corresponding to a backward velocity and a backward direction of the last trailer according to a user's operation. The control signal converter converts the first backward-motion control signal to a second backward-motion control signal which corresponds to a backward velocity and a backward direction of the car. The backward-motion controller controls the car based on the second backward-motion control signal so that the last trailer moves backward by the backward velocity and the backward direction corresponding to the first backward-motion controlling signal.
