Caller information providing apparatus and transmitting method in mobile communication network

Abstract: A caller information providing system and caller information transmitting method in a mobile radio communication network is disclosed. When a call comes in, the present invention provides a user at the terminating mobile station a picture information of a caller or caller information including a picture information, audio information, and/or character information of the caller.

Data transmission method and device in wireless communication system

Abstract: A data transmission method and device are provided in a wireless communication system with user equipment (UE). A UE transmits uplink data through sounding reference signals (SRS) and a physical uplink shared channel (PUSCH) in a SRS subframe. A single carrier-frequency division multiple access (SC-FDMA) symbol allocated to said SRS and the SC-FDMA symbol do not overlap within said SRS subframe.

Apparatus for controlling power of processor having a plurality of cores and control method of the same

Abstract: Embodiments of an apparatus and methods for controlling power of a processor having a plurality of cores can independently control individual or selected cores and power supply circuits corresponding to the cores based on, for example, an operation state of the processor or a power mode. Embodiments of an apparatus for controlling power of a processor having a plurality of cores can include a plurality of power supply units each capable of independently supplying a supply power to a plurality of cores provided in one processor, a unit for checking at least one among a use state, a use amount and a power mode of each core and for turning on/off each checked core, and a unit that contacts with the unit for checking for controlling the power supply units in response to an on/off operation of each core.

Ultrahigh-density phase-change data storage without the use of heating

Abstract: Non-volatile memories based on scanning probes offer very high data densities, but existing approaches require the probe to be heated, which increases the energy expenditure and complexity of fabrication. Here, we demonstrate the writing, reading and erasure of an ultrahigh-density array of nanoscopic indentations without heating either the scanning probe tip or the substrate. An atomic force microscope tip causes microphase transitions of the polystyrene-block-poly(n-pentyl methacrylate) of a block copolymer to occur at room temperature by application of pressure alone. We demonstrate a data storage density of 1 Tb in(-2), which is limited only by the size of the tip. This demonstration of a pressure-based phase-change memory at room temperature may expedite the development of next-generation ultrahigh-density data storage media.
