Abstract: Provided is a semiconductor device for compensating for an internal skew without training with an external device. The semiconductor device includes a signal generating unit configured to generate and output a reference signal, a first receiving unit configured to receive the reference signal and output a first output signal, a second receiving unit configured to receive the reference signal and output a second output signal, a delay unit configured to delay the first output signal by a certain time and output a delayed signal, a sampling unit configured to sample the second output signal based on the delayed signal and output sampling data, and a skew controlling unit configured to control the delaying unit based on the sampling data.

Abstract: A data processing device includes a clock converter, a data converter, ad an error detector. The clock converter is configured to receive a first clock signal, convert the first clock signal into a second clock signal, and output the second clock signal. The data converter is configured to receive first data, convert the first data into second data using the second clock signal, and output the second data. The error detector is configured to check whether the first clock signal is in a first clock state or a second clock state upon the first data transitioning to a first data state, and output an enable signal to the clock converter upon determining that the first clock signal has transitioned to the first clock state from the second clock state.

Abstract: Provided is a root mobile router and the operating method thereof in a dynamically composed moving network, capable of forming a self-configuring ad-hoc network between wireless personal area networks (WPANs) of each user in a moving network and supporting a stable connection between the network and the Internet. The method includes the steps of: receiving state information of multiple access networks and selecting an optimal access network in order to connect to the Internet; receiving a result of the selection and activating an interface of the selected access network; changing the selected access network to the activated access network interface; and updating routing path information automatically and stably transmitting an IP packet to the Internet through the selected access network interface. Therefore, a personal mobile terminal can be utilized as a mobile router.

Abstract: The present invention relates to the monitor having ribs for fixing a CRT comprising a CRT, a shield cover which is assembled enclosing said CRT from behind and a monitor case composed of at least two covers which enclose said CRT and said shield cover, and are joined one another by joining members, wherein the ribs for fixing the CRT are formed protruding from the inner surface of said monitor case in accordance with the shape and contours of the outer periphery of the CRT so that the CRT is fitted into the ribs and secured by joining force between said covers which are joined by said joining members. Since the CRT is fixed by the binding force between the covers comprising the monitor case and by said fixing ribs for the CRT, fixing lugs at each edges of the CRT are not necessary. Accordingly, there arises a merit that the size of the monitor can be reduced close to the actual screen size.
