A position-controlled wave power generating apparatus. A position-controlled wave power generating apparatus is included a floating part floatable on a body of water, a motion conversion unit coupled to a floating part, a power generating unit generating electricity using a generator connected to a motion conversion unit, and a position control unit positioned below a water surface to generate a thrust from the energy of waves.
摘要:
A method and apparatus for efficiently transmitting data in an MIMO communication system are provided. The method includes receiving first Channel State Information (CSI) fed back from a plurality of terminals; requesting feedback of second CSI from the respective terminals, the second CSI differing from the first CSI; and determining the terminals to be grouped by using at least one of the first CSI and second CSI, when the second CSI is fed back from the respective terminals.

Disclosed are cross-layer optimization method where information about lots of dynamic changes in wireless environment is shared and cross-layer optimization is implemented and abstraction layer component. Multimedia transmission layer operating method where optimization of first layer and second layer is implemented by using service information provided from first layer having transmission layer and network layer and second layer lower than datalink layer. The operating method includes upward abstraction step where service information provided to second layer is processed and processed service information is provided to multimedia transmission layer and downward abstraction step where indication information provided from multimedia transmission layer is processed and processed service information is provided to second layer. Consequently, there is advantage that all layers share diverse information about lots of dynamic changes in wireless environment, and the diverse information can be controlled to allow transmission where QoS is ensured more effectively.

Disclosed herein are a method of changing a receiving mode in a mobile terminal, and a mobile terminal thereof. The method includes entering a charging ready mode when the mobile terminal is positioned adjacent to an external wireless power transmitting module; determining whether the receiving mode of the mobile terminal is a vibration mode; and, when the receiving mode of the mobile terminal is the vibration mode, changing the receiving mode of the mobile terminal to a non-vibration mode.
摘要:
A method and apparatus for expanding a bandwidth of an input narrowband voice signal is provided. The narrowband voice signal is analyzed separately for each frame, and a Degree of Voicing (DV) and a Degree of Stationary (DS) are calculated depending on the analysis. A Degree of Difficulty of Bandwidth Expansion (DDBWE) of the narrowband voice signal is calculated based on DV and DS. Bandwidth expansion is controlled according to DDBWE.
